Product Details

What is the mild steel square tube?

The square tube is a welded hollow square-cut steel tube that is specifically designed to be used in all types of construction projects. Either the type A513 or A500 Grade B, depending on its size and wall thickness. The square steel tube shape design allows for increased rigidity and strength compared to other steel product shapes. For the grade ideal for all structural applications, general fabrication, manufacturing, and repairs. Square steel tubes can also be cut, formed, machined, and welded to your exact specification. The shape configuration allows for much greater strength and rigidity compared to angles or channels. This steel tube shape is easy to weld, cut form, and machine with proper equipment and knowledge.

A500 Gr-B	Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.
A513	Offers high weldability and is used frequently in structural applications in bridges and buildings as well as in both the automotive and appliance industry.

Carbon Steel Structural Hollow Sections Packaging and Advantages

Types of Packaging:
Bundles (hexagonal)
Wooden Boxes
Crates (steel/wooden)
Special crates for Structural Hollow Sections with each radius separated
Packaging for Carbon Steel Seamless Pipe as per customer’s requirements

Mild Steel Square Tube Advantages:

High Strength
Resistant High Mechanical Stresses
Resistant to High Pressure
Resistant to High Temperature
Good Formality
Reusable

Stainless Hollow Section

304	Offers resistance to corrosion, has good formability and can be readily welded by all methods. One of the most commonly used grades across the industry.
304L	Extra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties.
316	Better pitting and corrosion resistance than 304, as well as higher strength at elevated temperatures. 316 can be used for valves, marine equipment, pumps, and chemical equipment.
316L	Extra low carbon avoids harmful carbide precipitation due to welding. Same excellent corrosion resistance as 316. It exhibits the same high strength, toughness and workability as 304 alloys.
