December 5, 2016Square 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.
Square Tube is commonly available in Aluminum, Stainless Steel, Hot Rolled Steel and Cold Rolled Steel. It can be purchased online and at any Metal Supermarkets location. It can be cut to your exact specifications.

APPLICATIONS of square tubing
Structural Steel Tubing can be used for a wide range of mechanical applications. It may be used either statically or dynamically. close tolerances, good surface, and thick structure make it perfect for parts such as structural assistance and parts, frames, racks, trailer beds and trailer elements, structural elements and supports for structures, highways, and bridges, conveyors, machine parts, guides, and supports, security and deck rails, indication posts, athletic equipment, ornamental usages and a large range of applications in commercial, construction, automobile, appliance, furnishings and agricultural markets.
