The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding.
Square tubes are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Square tubes are generally used for maintenance and structural purposes. Some examples of applications would be building construction, railings, and sign posts. They are measured by their outside dimensions and their wall thickness.
Rectangular tubes are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Rectangular tubes are generally used for maintenance and structural purposes. Some examples of applications would be building construction, railings, and truck frames. They are measured by their outside dimensions and their wall thickness.
Rectangular Tube is commonly available in Aluminum, Stainless Steel, Hot Rolled Steel and Cold Rolled Steel. It can be cut to your exact specifications.
We manufacture variety of customized cold roll forming profiles based on customer's requirement. We have a team of experts who assures 100% defect free product.
It is manufactured from cold rolled steel which is then zinc coated and clear passivated. This ensures its strength and corrosion proof properties. Available in various lengths and slotted and un-slotted (perforated) profiles for easy attachment and wiring.
