St Helens Depot

From our depot in St Helens we believe we have an excellent mix of stock in reversing mill plate in S275JR/S355JR/S355J2 & 400HB and strip mill coil in DD11/S275JR & S355JR. We keep a wide range of thicknesses and sizes in mill certified sheet and plate, as well as prime over-rolled sheet and plate in non-standard sizes.

We pride ourselves on being the UK’s leading supplier of miscellaneous plate in S275/S355. It doesn’t hold a mill certificate but can be offered with/without a lab certificate for non critical certified applications. In an industry where every penny counts, miscellaneous plate offers great savings over prime certified plate!
