Square Tube

Square Tube

Square Tube is an extruded product that is widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary concern. Square Tube has square corners inside and outside, with no weld seam.

Carbon Stainless Aluminum

Carbon

GradeDescription
A500 Gr-BStandard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.
A513Offers high weldability and is used frequently in structural applications in bridges and buildings as well as in both the automotive and appliance industry.

Stainless

GradeDescription
304Among the most commonly used grades across the industry, it offers resistance to corrosion. Has good formability and can be readily welded by all methods.
304LExtra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties.
316Better 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.
316LExtra 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.
409Lowest cost in terms of stainless, used in automotive exhaust systems. It's resistance to oxidation and corrosion is good, the finish or look does not matter.

Aluminum

GradeDescription
6061Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
6063Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
