Carbon Steel & Stainless Steel: high spec, wide choice

From our beginning as a small steel plate supplier, we have progressively expanded our range of services and now we can deliver finished parts ready for assembly. For instance, we have worked with specialist sub-contractors to provide a complete tank farm ready for on-site erection.

Our focus is on the supply of highly specified, quality steel plate products with one of the most diverse stock ranges available anywhere in the world, running from carbon manganese through to super duplex stainless steel. Whatever your ex-stock steel plate requirement, the chances are we can offer a speedy supply solution.

Our strategically located warehouses and processing facilities in the UK , Belgium, U.A.E. and Singapore allow us to ship to you quickly wherever you may be in the world; and our sales engineers and procurement specialists will advise on the best products for your needs.


Whether you need an offshore specification plate in Singapore, an HIC plate in Brazil or a pressure vessel plate in Bradford, we have the stock and logistical skills to deliver what you want when you need it.

Plates are available in a wide range of carbon manganese, alloy, and stainless steels in numerous specifications and grades.
