Properties

Amstrong® steels are characterised by high ductility, controlled internal purity, fine grain structure and low carbon content.

On request, Amstrong® may be delivered with an improved surface finish on black hot-rolled product called MASC (Micro Adhesive Scale). Contact our commercial teams for further information.

Advantages

Amstrong® steels combine:

With their high strength, they are an excellent choice when weight-saving is a priority, and are frequently used to replace structural steels.

Applications

High strength Amstrong® steels are used in a wide range of applications in transport (earth movers, trailers, agricultural and railroad machinery etc), profiling (racks etc) and building (cranes, safety barriers, light poles etc). Significant weight reductions can be achieved by using Amstrong® steels, especially for cranes and heavy vehicle trailers, thus allowing a larger payload.
