Description

Galvanized Square Tubing

Galvanized square tubing is made by forming and welding galvanized steel coils, or by hot-dip galvanizing black carbon steel welded square tubes. The galvanized square tubing produced by Yuantai Derun is produced using the two methods mentioned above. It has the advantages of wide coverage, uniform wall thickness, tight and sturdy welds, and high zinc layer thickness, making it a very popular metal building material.

Strictly Follow The Acceptance Standards For Galvanized Square Pipes During Production

Galvanized square tubings are generally judged based on the appearance of the product to determine whether they are qualified. If there are missed plating, pitting, white spots, double skin, bubbles, green discoloration on the surface of the outer wall of the square tube, and the frequency of occurrence is too high, it is determined as an unqualified product. But in product standards, there is a specified range of deviations for products, which is the "allowable deviation" of dimensions. If you have any questions, please contact the customer manager of Yuantai.

Theoretical Weight Calculation Formula For Galvanized Square Tubing

Calculation formula for ordinary square tubes per meter: (length+width) * 2 * wall thickness * 0.00785=weight per meter, while calculation formula for hot-dip galvanized square tubes: (length+width) * 2 * thickness * 0.00785 * 1.06=weight per meter

Application

The galvanized square tubings produced by Yuantai Derun are applied in industries such as construction, steel structures, shipbuilding, fitness equipment, mechanical equipment, large agricultural machinery, carports, photovoltaic projects, greenhouses, truck manufacturing, aviation equipment, and power equipment.

Galvanized Square Tubing For Carports

When building an open-air carport, galvanized square tubing is one of the raw materials used. It not only provides strong support, but also effectively prevents structural corrosion of the carport, greatly improving the service life of galvanized square tubing.
