Wide Coil Sizes and Grades

Standard widths of coil is 1219mm (4’) but other widths can be supplied on request up to a maximum of 1524mm (5’). 

Thickness from 0.4 - 3.0mm available.

Wide Coil Characteristics

Made from stainless steel AISI 304/316.

They offer good formability, corrosion resistance, toughness and good mechanical properties. As a result they are widely used for insulation and engineering applications. These grades are non-magnetic in the annealed condition.

Wide Coil Corrosion Resistance

These steels exhibit excellent resistance to a wide range of atmospheric, chemical, textiles, petroleum and food industry exposures. 

Type 316 and 316L exhibit better corrosion resistance than type 304.

Weights and Packaging

Coil weights from 1000 - 2000 kgs, other weights upon request.

Can also be supplied in sheet from, 2000 x 1000mm - other sizes on request. Export packed in weather proof packing suitable for container shipping.

Fumigation of wooden packing materials can be arranged if required.
