Corrosion Resistance
The G90 galvanized coating is the key to the corrosion resistance of Sunnyda galvanized square tubing. We offer steel tubes with zinc coating thicknesses ranging from 30 to 275 g/m², with multiple grades available.
The zinc coating protects your steel from moisture, chemicals, and air exposure, helping prevent rust and corrosion. You get reliable performance even in wet, humid, or chemical environments. This extends the tubing’s service life and reduces replacement and maintenance costs caused by corrosion.
Materials and Processes
Sunnyda galvanized square tubing is made from zinc-coated steel compliant with ASTM A500B/A513 standards. This material combines the strength of steel with the corrosion resistance of zinc. This ensures your tubing has the strength you need for structural support while resisting corrosion. In terms of manufacturing processes, we employ both cold-rolling and hot-rolling techniques. You get excellent quality because every tube is produced under strict process control.
Dimensions
You can choose sizes that match your project requirements. We know your conditions, so we offer a wide range of galvanized square tubing specifications. Whether for light-duty structural applications or heavy-duty industrial equipment support, you can find the appropriate wall thickness specification. This helps you reduce cutting time and improve installation efficiency.
You can choose from a wide range of sizes to fit your project:
- Wall thickness: 0.25 mm to 2.5 mm
- Size range: 5/8″ to 4″ square tubing
- Length options: 10 ft, 12 ft, 14 ft, 24 ft
We can also customize larger sizes to meet your specific needs.
High Strength
In the construction and industrial sectors, the strength of steel tubing is critical. Sunnyda galvanized square tubing features a high yield strength of 46,000 psi and a tensile strength as high as 58,000 psi. This means your structure stays strong and stable under load. Additionally, you get a strong strength-to-weight ratio, making transport and installation easier. It reduces shipping costs and installation complexity while improving construction efficiency.
Extended Lifespan
When you choose Sunnyda galvanized square tubing, your tubing can last up to 50 years with proper use. Whether used as foundation supports for large-scale buildings or in piping systems for industrial facilities, Sunnyda galvanized square tubing performs reliably. You spend less on maintenance and replacement.
