Introduction

This frequently asked questions document is designed to guide business owners, builders, contractors, engineers and consultants on Galvanized Beams benefits; it covers all primary aspects of galvanized beams application, production process, grades, standards, galvanization types, coating thicknesses, customization, and many more.

Galvanized Beams

Q1: What Are Galvanized Beams?

Galvanized Beams are steel or iron beams that have been passed through a rich galvanizing process. Galvanizing involves applying a zinc coating to steel beams in order to provide greater protection against corrosion and achieve rust-free protection, hard surface coating and durability. Galvanizing forms a barrier through its zinc sacrificial anode properties which prevent any corrosive elements to reach the underlying steel.

Galvanized Beams can be designed and manufactured in many structural steel shapes and profiles including:

I Beam; H-beam; C Beam; W Beam; T Beam; WT Beam; U Beam, ST Beam; Wide Flange Beam; S Section; HSS; etc…

They are available in a wide range of grades, sizes, strengths, chemical composition and mechanical properties that respond to all countries’ standards and building codes.

Galvanized Beams are an economical alternative to aluminum and stainless steel, it can be easily machined, welded or cut using regular steel tools.

Q3: What Are The Processes Involved In Galvanizing Beams?

The process of galvanizing beams involves applying a thick, robust layer of zinc coating to the beam steel surface. Galvanized Beams passes by the following steps:

Surface Preparation

This step is very important as steel beam materials should be perfectly cleaned to enable steel and zinc proper reaction.

Degreasing

The process consists mainly of removing organic contaminants such as oil, grease, dust from metal surfaces.

Galvanized Beams

Pickling

To remove mill scale and rust the steel beam materials are immersed in an acid bath of hydrochloric or sulfuric acid.

Fluxing

The material is finally fluxed into a bath of an aqueous solution of zinc ammonium chloride to retards further steel oxidation and promotes steel and zinc reaction.

Galvanizing

This process involves immersing the complete beam steel material in a bath of 98% pure molten zinc until it reaches 850 degrees Fahrenheit temperature. This operation is for objective to enable a complete metallurgical reaction of steel and zinc in order to form one pure zinc layer and three zinc-iron intermetallic layers.

Pre-inspection

Pre-inspection is conducted to ensure galvanized beam materials have the required design characteristics, coating quality, proper holes and bracing, etc…

Final Inspection

This is a visual check which ensures galvanized beam has the required appearance and uniformity specifications, a variety of laboratory tests and magnetic thickness gauge test are performed to check the conformity of galvanized beams thickness and zinc coating.

Galvanized Beams

Q4: What Are The Materials Used To Produce Galvanized Beams?

Zinc Coating

Using Zinc in the galvanization process can ensure very efficient and long-term anti-corrosion protection to galvanized beams even in the most corrosive environments. This is due to its chemical and physical properties. The zinc coating can also, protects galvanized beams from galvanic corrosion or bi-metallic corrosion in case it’s drilled, cut, or when inserting uncoated fasteners.

Zinc coating forms a protective layer that acts as a barrier that prevents the steel from being in contact with air, water and other environmental issues. Through its amphoteric oxide, basic carbonates, hydrated sulfates and strong alkalinity, zinc reacts like a physical metallic barrier that offers an excellent resistance to abrasion and protects underlying steel beams from being exposed to atmospheric conditions.

Q5: Why Zinc Is Used In Galvanized Beams?

Galvanization act as a barrier between the steel and the atmosphere. Because of its electropositive (active) metal characteristics when steel is exposed to the atmosphere, zinc acts as a barrier between the steel and the atmosphere and continues to protect steel through galvanic corrosion.

Zinc has many advantages when used in the galvanization of steel beams, below are some reason why it’s preferred instead of other metals:

Durability

Zinc is essential to ensure the longevity of galvanized beams; it can easily provide protection for over 100 years maintenance-free if galvanization is professionally applied.

Oxidation Protection

Zinc provides long-term sacrificial/catholic protection and prevents sideways creep deterioration of galvanized beams. Because Zinc is more reactive than any other metal type, it can protect galvanized beams from oxidation (loss of its electrons). Zinc acts “sacrificially” to a steel beam, this means that when zinc is in contact with steel it will react with oxygen more readily than iron and acids will attack the zinc rather than the steel beneath it and hence, Zinc will be oxidized instead of the iron.

Water Corrosion

Because Zinc is an amphoteric metal that has a pH near neutral, it can provide a good corrosion resistance rate to galvanized beams in soft, hard and distilled water.

Galvanized Beams

Soil Corrosion

Due to the neutral slightly alkaline pH of soils, and because of its chemical and physicochemical properties, limited corrosion is likely to occur to galvanized beam placed in soils.

However, in order to protect steel beams from the aggressiveness of soil corrosion and prevents pitting of galvanized beams in soil and deterioration, galvanized beam coating thickness should follow the guidelines of ASTM G51-18 standards Test Method for Measuring pH of Soil for Use in Corrosion Testing.

Q6: Why Builders Prefer To Use Galvanized Beams?

Builders from different industries prefer to use Galvanized Beams for their proven reliability, versatility, sustainability and for the outlined advantages below:

Lowest cost and highest Strength

Galvanized Beams are an economic substitute to other commonly used expensive protective beam steels such as aluminum and stainless steel beams. In addition to being affordable, galvanized beams offer high strength, durability and excellent corrosion resistance.

Performance in all environments

Because of its protective galvanized coatings which consist of insoluble zinc oxides, hydroxides, basic zinc salts and carbonates properties, galvanized beams provide great corrosion resistance in the harshest environment, in soil, water, concrete, etc…

Warm Dry Atmospheres

Galvanized beams can perform well under the most extreme hot temperatures (392 F/ 200 C maximum). Due to its zinc protective properties, galvanized beams remain very stable in warm dry atmospheres, the layer of zinc formed reacts as a protective patina that prevents a further reaction between the galvanized coating and the air.

Galvanized Beams

Atmospheric moisture

Either in atmospheric moisture, air salinity, humidity, rainfall or sulfur dioxide pollution, galvanized beams zinc oxide patina remains stable and non-reactive unless it’s exposed to aggressive chlorides or sulfides which are crucial to the longevity of galvanized beams.

Coastal Areas

Despite the rate of corrosion which increases in coastal areas due to marine atmosphere soluble chlorides, sea sprays, saltwater, distance from the sea, wind speed and direction. Galvanized beams offer optimum protection in most marine environments. A hot-dip galvanized structural steel of >1/4-inch thick can last 75-80 years to first maintenance even in the most corrosive coastal environment.

Furthermore, the local rate of weathering of any given galvanized beam coating can be reliably predicted and exactly calculated to suit the required application and avoid any unexpected surprises.

Industrial areas

Industrial areas are generally characterized by an aggressive corrosion rate because of air emissions which cause coating consumption due to atmospheric impurities, phosphates, sulfurous gases, sulfides and chemicals of industrial facilities plant exhaust and truck emissions.

In spite of that, galvanized beams still can secure sustainable and adequate protection for the light industrial corrosive environment, while, in heavy industrial areas characterized by extremely corrosive conditions, reinforced galvanized beams coatings are recommended in addition to a resistant paint system.

Aesthetically pleasing

Galvanized beams are rapidly becoming a top choice in modern architecture; it offers endless design and aesthetics to the interior and exterior of structural steel (AESS), it allows maximum span to be achieved, space efficiency along with and optimum corrosion protection.

Galvanized Beams

Durability and Longevity

Galvanized beams are generally expected to last up to 100 – 150 years without maintenance; this life expectancy may be reduced if exposed to insecticides or aerial spraying of fertilizers as they are harmless to zinc coatings.

Reliability

Galvanized beams are designed and manufactured and regulated under specific international standards including minimum coating thicknesses to be applied to different steel beam applications. Whereas, galvanized beams coating performance and lifespan can be predicted, tested and measured.

Complete Protection

Galvanized beams surface is completely protected, even inaccessible areas, recesses and sharp corners are covered properly by zinc coating. While, several inspections and quality checks are conducted according to ensure Galvanized beams maximum performance, reliability, corrosion protection and compliance with international standards.

Galvanized Beams Quality Inspection

Galvanized beams coatings should appear sound and continuous, various testing methods are used to ensure providing the right galvanized beams coating thickness such as nondestructive testing, ultrasonic thickness gauge testing and laboratory run testing to monitor, measure and inspect galvanized beams coating thickness.

Easy and Faster Erection Time

Galvanized beams are delivered ready for erection, this saves significantly the assembly time and labor cost. No surface protection, painting or inspection is required. Thus, the complete structure can be assembled quickly and delivered for the next construction stage.

Galvanized Beams

Q7: What Is The Thickness Of Galvanized Beam Coating?

The galvanized Beams coating thickness depends largely on the gauge of the steel, and the environment where it will be used. Its soul meets the purpose of steel beam application.

Generally, galvanized beams’ coatings thickness range from 3-8 mils (75-200 microns).

For Hot-dip galvanized beams there no limit is set on the thickness while the thickness is 7mm.

To ensure the right normal coating thickness levels and adherence of galvanized beams coating, and eliminate stress on temperature cool down and thermal contraction, coating thickness should not exceed 10 mils.

Galvanized Beams coating thicknesses are measured using an appropriate magnetic devices; they are produced using batch hot-dip galvanizing standardized process which produces a quantifiable coating thickness. ISO 2178:2016 technical standards for Non-magnetic coatings on magnetic substrates and Measurement of coating thickness are applied.

Q8: What Are The Common Grades Of Galvanized Beams?

ASTM A653/A653M

ASTM A653 standard defines steel sheet, zinc-coated Galvanized or zinc-iron alloy-coated Galvannealed by the hot-dip process in coils and cut lengths. It states various zinc or zinc-iron alloy-coating weights or coating designations that can be applied to steel beams.

Galvannealed steel beams are produced through galvanizing and annealing process, to get a matte uniform grey color finish that can be easily painted, whereas galvanized beams coating provides a harder and more brittle finish.

Galvannealed beams are designated with an “A” like A40 and A60, while, galvanized beams are designated with a “G” (G40, G60 and G90).

G90 Galvanized Beams

G90 grade of galvanized beams follows ASTM A653 standards, they are hot dipped in zinc and coated with a minimum coating thickness of 0.9 oz/ft², this method takes into consideration the coating thickness on both sides of the steel beams or 0.45 oz/sq. ft. per side, this offers excellent corrosion resistance to galvanized beams and makes them more suitable for exterior applications.

Galvanized Beams

A60 Galvanized Beams

A60 galvanized beams grade offers 0.30 oz/sq. ft. per side, after being galvanized they are annealed to produce a surface that enables a smooth adhesion of paint.

A36 Galvanized beams

A36 Galvanized beams are a hot rolled, low carbon and low alloy steel that has been passed through a hot-dipped zinc-rich galvanizing process. This increases corrosion resistance while the advantage of low carbon content (less than 0.3% carbon) made it essential for general steel construction purposes as it offers more flexibility and extremely useful in forming, machining and welding.

ASTM A572-50 Galvanized beams I and H beams

ASTM A572-50 galvanized steel I and H beams are very popular, they are widely used in construction applications such as bridges, transmission towers, residential, commercial and industrial buildings. In addition to its economic price, it can provide more strength per unit of weight and optimum atmospheric corrosion. A572 has a higher tensile strength and yield point in comparison with A36.

ASTM A992 Galvanized beams

ASTM A992 is the preferred material for structural wide-flange galvanized beams, it offers more ductility, weldability and a maximum yield-to-tensile strength ratio of 0.85.

Galvanized Beams

Q9: What Are The Standards Governing Galvanized Beams?

ASTM A123

• Slightly shiny.

• Silver color.

• Grey color.

• Spackled surface.

• Grainy

• Matte

Q12: How Does Galvanization Protect Beams From Corrosion?

Protective Zinc coating used in the galvanized beams processed either by hot-dip galvanizing or electroplating technology forms an impervious barrier between the steel substrate and corrosive elements in the environment, and thus, transfer the rust created on the steel beams on the zinc layer and protect the galvanized from damage. Zinc being anodic it can also prevent moisture and any other corrosive substances such as corrosive chlorides and sulfides that might attack the galvanized beams.

Galvanized Beams

Q13: Are Galvanized Beams Waterproof?

Yes, Galvanized Beams are Waterproof, because of the zinc properties they stand up to corrosion even if submerged in water. However, parameters such as pH level, oxygen content, agitation, the water temperature can affect corrosion of zinc in a water environment.

So, to decide about the right galvanized beam coating that suits your application, it is better to identify the type of water. Water is classified under different types according to its mechanisms which determine the ultimate corrosion rate:

• Seawater

• Pure water(distilled water or de-ionized water).

• Natural freshwater.

• Potable water (treated drinking water).

Q14: Is The Cost Of Galvanized Beams Economic Compared To Other Corrosion Protection Systems?

Compared with paint protection performance, hot-dip galvanized beams has a less expensive initial cost because of it has a lower life-cycle cost, hot-dip galvanized beams remains the smart choice to ensure durable economical corrosion protection and eliminates recurring maintenance and surprising results.

For manufacturing facilities when the time-value of money, hot-dip galvanized beams throughout its life-cycle costs is very economic, while they remain the most cost-efficient materials to substitute stainless steel and aluminum beams.

Q15: What Is The Difference Between Galvanized Beams And Stainless Steel Beams Price?

Galvanized Beams cost is almost similar to untreated steel beams, stainless steel costs five times higher than galvanized beams while Niobium Alloys Beams are very costly.

Galvanized beams are widely used as stainless steel alternatives, especially, in applications where superior life-cycle and corrosion resistance are needed without the cost of stainless steel. Galvanized beams can also provide a typical crystallization pattern or spangle as stainless steel beams.

Galvanized Beams

Q16: Is Galvanized Beams Better Than Stainless Steel Beams?

Galvanized beams are more ductile, easier to work than stainless steel, it can be easily machined, welded formed, and cut. It can provide maximum corrosion protection. Whereas, stainless steel has more strength and can also resist corrosion efficiently.

Q17: How Long Can Galvanized Beams Last?

Hot-dip galvanized beams can provide up to 250 years of corrosion protection and can last up to 75 years in harsh corrosive environments.

Q18: What Is The Difference Between Pre-Galvanized Beams, Batch Hot Dipped Galvanized and Electro-Galvanized Beams?

Pre-Galvanizing or Mill-Galvanized

This method is performed at the steel mill and involves the same process as hot-dip galvanized beams; it’s applied to steel beams with a specific shape. The rolling metal sheet passes through a cleaning process, followed by being dipped in a pool of hot molten zinc, cut to size and then recoiled.

The advantage of the pre-Galvanizing method is that it enables rapid processing for large quantities of steel beams and offers a more uniform coating compared to hot-dip galvanizing. The only disadvantage is that once the galvanized beams are cut, the edges where the steel is cut are left exposed.

Batch Hot-Dip Galvanization

This galvanization type involves cleaning the steel either chemically or mechanically or even both, followed by being fluxed to rid any residual oxides that remain after the cleaning process. After these processes, the steel is dipped into a liquid bath of heated molten zinc at a temperature of 449 °C (840 °F) to form a metallurgical bond.

Hot-Dip Galvanization has many advantages, it’s more economic; it can be applied to complex beam shapes and can be performed quickly.

Galvanized Beams

Electro-Galvanizing

Unlike Pre-Galvanizing and Hot-Dip Galvanization production methods, Electrogalvanizing does not process galvanization in a molten bath of zinc. Instead, this process utilizes a running electrical current in an electrolyte saline/zinc solution with a zinc anode and steel conductor to transfer zinc ions onto the base roll metal sheet continuously. To ensure the smoothest zinc coating grain refiners are added.

Electro galvanizing ensure a good coating thickness precision and uniformity. It offers also, a thinner zinc coating than the one achieved by the hot-dip galvanizing method, this can reduce corrosion protection.

According to International Zinc Association, hot-dip galvanizing and electroplating have become very popular and mostly used all over the World for all construction and industrial applications.

Q19: What Is The Difference Between Zinc Electroplating Beams And Galvanized Beams?

Galvanized beams process involves applying a protective zinc coating to steel beams to prevent rusting.  The most common method used is hot-dip galvanizing where steel beams are fully dipped in a bath of molten zinc.

While Zinc electroplating or electro-galvanizing is the process of applying zinc to steel beams using a current of electricity to form a thinner coating.  Hot-dip galvanizing provides more corrosion protection than zinc plating. Electro-galvanized beams are more economic and easy to weld than hot-dip galvanized beams.

Galvanized beam finish provides a dull grey and a little rough appearance while zinc-plated beams are smooth and shiny.

Q20: What Does It Mean To ‘Double-dip’ Galvanized Beams?

Double-dipping in the process of galvanizing larger steel beams (a longer, wider or deeper than usual steel beam sizes) to fit into the relevant bath of molten zinc at approximately 460°C (860°F) to form zinc carbonate (ZnCO3).

The steel beam is partially galvanized, half or more of the beam steel is lowered into the pool of zinc. After achieving the required galvanized coating the remaining ungalvanized portion is processed.

Galvanized Beams

Q21: What Is ‘Cold’ Galvanized Beams?

‘Cold’ Galvanized Beams is more a marketing term than a Galvanization process; it’s used to describe coating steel beams with zinc-rich paint using normal paint tools such as blasting rollers and spray guns. This coating type is rich in zinc but it does not offer the durability and performance of hot-dip galvanizing in terms of abrasion resistance, corrosion protection and lifetime free maintenance.

Unlike galvanization which creates effectively a bond between the zinc and the beam steel of around 3,600 psi. ‘Cold’ Galvanized Beams paint contains binders and other elements which limit the connectivity of zinc particles and has bond strength with only a limited hundred psi.

Q22: What If the Steel Beam Is Of Large Size? Can It Still Be Galvanized?

Manufacturers can progressively process large-size steel beams by dipping the first half in a molten zinc bath, and immerse the other half in the zinc. This method is known as double-dipping.

Q23: Can Customers Specify The Quantity Of Zinc To be Used To Galvanize Beams?

No, the quantity or thickness of zinc to be used to galvanize steel beams is mainly dependants on steel chemistry and surface condition.

Galvanized Beams

Q24: Can Galvanized Beams Withstand High Temperatures?

Galvanized beams can perform well and ensure maximum protection even under constant exposure to higher temperatures ranging from 390 F (200 C) to 480 F (250 C).

However, under above 480 F (250 C) continuous exposure galvanizes beams might result in cracking the underlying zinc alloy layer and starts peeling.

Thus, low and moderate temperature climates are appropriate for galvanized beams purposes, while it’s not recommended to use hot-dip galvanized steel in an application above 480 F (250 C).

Q25: Can Galvanized Beams Be Painted?

Yes, galvanized beams can be painted; this process is named duplex coatings which combines galvanization and paint. It ensures double corrosion protection, extends the longevity of zinc coating and adds more aesthetics.

Q26: Does Galvanized Beams Cost More Than Painted Beams?

Galvanized beams are less expensive than painted beams on an initial cost basis. When a lifetime cost is considered along with corrosion protection, durability and maintenance also have a cost. Galvanized beams are more economic than painted ones it can last free of maintenance for more than 100 Years.

Paint coating requires periodic maintenance, and can last only for 30 Years. So painted steel beams are costly in the long run.

Galvanized Beams

Q27: How Can Galvanized Beams Prevent Wet Storage?

When galvanized beams are tightly stored in delivery boxes and especially in a humid and damp climate, moisture will accumulate on stored galvanized beams waiting to be shipped and cause wet storage stains. In order to provide customers with the highest quality galvanized beams, the manufacturer should:

Either remove standing water from the surface prior to delivery using a cleaner or nylon brush.

Store galvanized beams indoors or enable adequate air-flowing access between each galvanized beams article.

Q28: Are Slip-critical Connections Can Affect Galvanized Beams?

Galvanized beams have a lower slip coefficient being very smooth; however, to increase surface roughness. Slip-critical connections when used in galvanized beams; should be either abrasively blasted, brushed or painted with zinc-silicate paint.

Q29: Are Galvanized Beams Environmentally Friendly?

Zinc which mainly forms the beams’ galvanization composition is a natural element, so, it does not cause any harm to the environment. On the other hand, the galvanized beams production process is eco-friendly, sustainable and eliminates materials waste and increases the recycling rate.
