What is the HDG Square Hollow Section?

Square Hollow Section (SHS) is a welded structural grade tubing that is available in either type A513 or A500 Grade B, depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, manufacturing and repairs.

Steel square tube is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, frames, etc.

Its box-shape configuration allows for much greater strength and rigidity compared to angles or channels. This steel shape is easy to weld, cut, form and machine with the proper equipment and knowledge.

Metals Depot stocks hundreds of sizes of square tube at wholesale prices in ready to ship precut and mill lengths or you can order just what you need custom Cut to Size in any quantity. 

How to produce the Square hollow sections?

Hot-dip galvanizing is a form of galvanization. It is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). 

When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. The process of hot dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys.
