Introduction

Structural steel columns are almost used in every building in the world; it has become one of the most prevalent construction materials that support the rapid development of modern architecture. But what exactly are structural steel columns? Why do builders use it? Are they sustainable and environmentally friendly? All of these questions and more will be thoroughly answered in this frequently asked questions document.

For more information about structural steel columns, please contact us at:

Q1: What Are Structural Steel Columns?

Structural steel columns  are vertical support structural members intended to carry the accumulative weight of steel structures, they are used to transfer loads from beams, floor/roof slab, or from a ceiling, to a floor or foundations. Structural steel columns are a compression members designed mainly to resist stress that comes from axial forces, bending moments, shear forces and lateral loads of wind or earthquake.

 

Q2: What Are The Applications Of Structural Steel Columns?

Due to its high strength to weight ratio, rigidity, versatility and cost benefits, structural steel columns are the material of choice in every construction site, they are used across a wide range of small and large construction applications including the following:

 

Buildings

Structural steel columns are a cost-effective building material used in all construction projects to maximize structure’s strength and durability and minimize the cost and speed up projects completion. They are widely used in different building types, ranging from low, mid and high rise buildings including industrial structures, manufacturing facilities, warehouses, hospital and school buildings, aircraft hangars, stadiums, metro stations, etc.

because of its outstanding properties, longevity and flexibility of design, structural steel columns are preferred by almost all architects, designers and contractors, its available in various grades that can offers excellent corrosion resistance even in the harshest environments. Unlike other building materials, structural steel columns are lightweight and take a little space. No matter is the overall size of the structure or floor space; structural steel columns can be designed to suit all architectural requirements in terms of size, shape and finishing.

 

Infrastructure

Infrastructure construction industry relies heavily upon structural steel columns more often than other materials; they are designed and fabricated with the main objective to provide high tensile strength and excellent stability, ductility and malleability that can withstand extreme loads of roads, railways, tunnels, bridges, oil and gas structures, and all other megaprojects. Because of its high level of corrosion resistance they are the most preferred building material for infrastructure applications situated over water or near coastal areas.

 

Ship Building

Structural steel columns are extremely useful in ship building industry; they are designed and manufactured to offer the necessary strength, weldability, and corrosion protection required to build resilient ship structures that ensure maximum safety on board and facilitate carrying precious cargo everywhere in the World. Structural steel columns can be fabricated to exact specifications, shapes, sizes and finishing to suit different ship applications including oil tankers, submarines, boats, ship loaders, etc.

 

Mining

Most of the mining sub-structures are built using structural steel columns wic can be designed to support mining screens, fluidized bed boilers, workshops, equipments used in the mining operations. To ensure durability and maintenance free application, structural steel columns can be protected by hot-dip galvanization or powder-coat painted to withstand mining sites abrasive conditions.

 

Energy

Structural steel columns are used in many energy steel structure applications including nuclear power, power plants, electric power, oil and gas infrastructures, pipelines, coal structures, transmission towers, wind turbines, catwalks and crossover bridges.

Q3: What Are The Benefits Of Structural Steel Columns?

Using structural steel columns in major construction project bring countless economic and environmental benefits; below we have outlined some of its main benefits:

Higher strength/weight ratio

Structural steel columns are designed and fabricated to be used as heavily loaded members in low, mid and high-rise buildings, towers, bridges, roads, etc. high-strength steel are used to provide high specific strength or strength/weight ratio.

High ductility

Ductility is an important factor in engineering, it’s defined as material’s capacity to absorb mechanical overload, because of its mechanical properties, structural steel columns can commonly withstand loads, sustain deformation and bending stress without failure.

High Toughness

Toughness specifies how much energy a structural steel column can absorb before rupturing and its ability to plastically deform without fracturing. In order to provide high toughness values and enable the whole steel structure to withstand high compressive stresses and strains, structural steel columns should be made from strong and ductile steel materials.

Versatility

Structural steel columns are the most versatile construction materials; they offer an incredible flexibility and freedom in designing iconic buildings, towers and bridges. Structural steel columns can be fabricated and customized at factory to suit customers functional and aesthetics requirements in colors, finishes, span, sizes, customization features, and more.

Saving space

Structural steel columns are structurally efficient, they can offer greater space saving when compared with reinforced concrete; for example, a 40×40 cm2 structural steel column can be used in similar application as a 100×100 cm2 reinforced concrete carrier. Moreover, structural steel column depths are 50% less than that of a timber column. Using structural steel columns offers high strength thinner wall thicknesses, while brick walls are space-consuming, more usable area can be achieved and less material will be used when building with structural steel columns. Thus, structural steel columns are the most cost-effective method to reach more open plans with an extended spans and a space free from intermediate columns or load bearing walls.

Durability

When wood rots, concrete cracks, a properly designed and fabricated structural steel columns can provide a lifelong durability, however, while structural steel columns do not corrode in applications which are not exposed to oxygen, water or chemicals, corrosion in other structures which are more exposed to aggressive environments can be addressed by using a cost-efficient and effective sacrificial protection techniques such as zinc coatings, galvanization or other methods can be applied to steel surface to from a protective barrier.

Cost-Effective

Structural steel columns offers more economic benefits to builders, they are pre-manufactured off site at factory and delivered ready to be erected easily and quickly on-site. Furthermore, all drilling, welding, cutting, coating, finishing work is all completed at factory as needed. This minimizes costs of manpower and materials, while it speed up construction and help meeting project’s schedule. Compared to other materials such as concrete and wood, structural steel columns are lighter in weight and require less foundation.

Environmentally Friendly

Steel is the most recycled material on earth, when building reaches the end of its lifespan, structural steel columns can be reused or circulated in the recycling system. Moreover, most of structural steel columns are prefabricated in an environmentally responsible manufacturing facility that uses advanced technology machines that consume less energy and emit less CO2, this reduce negative impacts on the environment. Lean manufacturing production methods are applied also to eliminate waste of materials, improve efficiency and add value to structural steel columns.

Also, when structural steel columns are coupled with appropriate building design and materials such as high value insulation, they provide a comfortable and energy efficient interior that uses less energy, solar panels can be added to ensure a clean and renewable power.

Q4: What Are The Most Common Types Of Structural Steel Columns?

There are several types of structural steel columns which are used in different applications; they are available either with wide flange or tubular shapes as follow:

 

Hollow Structural Sections (HSS) columns

Hollow Structural Sections (HSS) columns are cold-formed steel tubes that are sapped in circular, rectangular, or square cross-section; they are mainly used for welded or bolted construction of various types of low, mid and high rise steel structures, bridges, and architecturally exposed buildings.

 

Steel Pipe columns

This type of structural steel columns is used mainly in exposed construction applications such as Architecturally Exposed Structural Steel (AESS), and for big offshore oil rigs and structures. They provide an aesthetically pleasant appearance, and high strength-to-weight ratio that ensure an excellent compression support and excellent torsional resistance.

 

Beam columns

H beams are widely used as structural steel columns in multi-storey buildings steel frames because of it can support axial and transverse loads, beam columns are called transversely loaded columns.

 

Universal Column (UC)

Universal columns are structural steel columns that are shaped as I or H capital letter; they are preferred in almost all construction applications because of its well performance under compression and buckling resistance. They are also known as Rolled Steel Joists (RSJ’s), I beams, H Beams or sections Beams.

 

Q5: Does Manufacturer Provide Structural Steel Columns Design?

Structural steel columns are designed mainly to fulfill structural integrity, durability and safety, different design analysis are conducted to ensure buckling and plastic resistance factors of structural steel columns in compression are fulfilled, this involve the determination of flexural-torsional buckling and elastic critical load minimum requirements. The design values of the loads including loads acting on columns from the influence area and cross-sectional area, safety coefficients are also calculated. The limit states Design (LSD) and the serviceability limit state design (SLS) have to be checked for each column to ensure overall stability, deflection, cracking, excessive vibration and fire resistance factors.

Q6: How Structural Steel Columns Are Protected Against Corrosion?

Structural steel columns does not need to be galvanized, primed or painted when they are used in construction with concrete or enclosed by building finishes, or when contact-type fireproof coating is applied. Corrosion protection should be applied only to structural steel columns that are exposed to corrosive environments with high humidity, water, oxygen or harmful compounds such as metal oxides, sulfates, sulfuric acid, chlorides. In this case, various forms of proven protective galvanization methods, high-performance coating systems and weathering steel can be used to provide long-term durability. Selecting the right type of corrosion protection is largely dependant to the determination of exposure severity, and initial cost versus lifecycle and future maintenance cost.

 

Q7: What Are The Finishing Types Of Structural Steel Columns?

Structural steel columns should be finished to a high standard to eliminate any corrosion or deterioration risk, especially when they exposed to high levels of atmospheric pollution or moisture. To provide an aesthetically pleasing appearance, steel surface should be firstly cleaned from any marks and grazes that may cause rusting risk, then it should be treated against corrosion using one or two methods of structural steel columns finishing, which are outlined below.

 

Galvanization

Galvanising is the most cost effective and efficient protective finish that can be applied to structural steel columns, it offer a superior protection against corrosion while it ensure a longer-lasting and maintenance free application in the most challenging environments. Galvanized structural steel columns can be exposed to high temperatures (up to 275°C); they can be also immersed in sea water, salt water, hot and cold water. Galvanization is applied by dipping the steel in molten zinc in order to form a metallurgical bonded physical barrier which will corrode in preference to the steel underneath the zinc, and in the meantime it prevent the underlying steel surface from being exposed directly to the atmosphere.

 

Primer

Primer paint is high in zinc phosphate, due this active corrosion-resistant material it is usually used before paint to ensure a better adhesion, increases lifespan, and provides additional protection. Primer paint is applied to structural steel columns to provide additional protection to steel surfaces that are exposed to corrosion, oxidation, and moisture.

 

Powder Coating

Powder coating is a free-flowing powder that can be applied to structural steel columns, the process involve applying electrostatically a dry finishing under heat to form a protective finish. This type of protective coating delivers an excellent resistance to corrosion, chemicals and weather. It’s a resilient rust inhibitor that is low in flammability and low also in toxicity and can last for up to 30 years.
