Materials

We are frequently asked about materials in terms of weight, strength, cost, corrosion resistance, weldability, finishes and where best to use each type. This is important since materials seriously affect the function and cost of a product.

As a general guide, mild steel, galvanised sheet, Zintec and Aluzinc weigh the same and have the same strength. Galvanised sheet and Zintec are about 7% more expensive than mild steel and Aluzinc 100% more expensive. They have varying degrees of corrosion resistance depending on how they are worked.

Stainless steel weighs about the same as mild steel, is twice as strong, harder and about 4 times as expensive.

Aluminium is one third the weight of mild steel, 75% as strong and costs about the same.

Further information about treating these materials can be found in Finishes.
