Cor-ten weathering steel S355JW sheet & plate A/B
Our sheet, plate and other parts are cut to order with our High definition XPR Plasma CNC machine, and on thinner sheets our fibre laser. Edges are always fully dross and burr free, squareness is assured both on the top side of parts and ISO 2 to 3 quality on edge bevel. Our XPR Plasma is the very latest brand new technology, we can also cut your own custom parts and have a instant online pricing and ordering system for these if required, of course you can still contact us directly for quotation.

Corten steel specification
Definition: Weathering means that due to its chemical composition the COR-TEN A steel, when utilized unprotected, exhibits increased resistance to atmospheric corrosion compared to unalloyed steels. This is because it forms a protective layer on its surface under the influence of the weather. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In general the covering layer offers protection against atmospheric corrosion in industrial, urban and country-side climate. In cases of particular air pollution by aggressive agents conventional surface protection is recommended. Coating is absolutely necessary in cases of contact with water for long periods, when permanently exposed to moisture, or if it is to be used in the vicinity of the sea. The susceptibility of paint coats to undercreepage by rust is less in the case of weathering steel than in the case of comparable non-weathering steel.
Application: The steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions.
Density of this 20mm thickness material is 7.85 g/cm3, or 157 kg per square meter of material.
We cut our steel on a state of the art industrial plasma CNC machine. It is the highest accuracy model produced by Esprit Automation Ltd the "Lightning HD" and coupled to this machine is Hypertherms latest XPR 300 plasma. This offers us the best possible edge quality, cut and bevel in the 2-3 ISO range on the edges. Accuracy is our priority, we will also set out to ensure we have the best machinery with the best accuracy we can find to use in our business.
