Quarto, CPP and cold rolled plate, in the grades that build the toughest applications.

Stainless steel plate takes over when the job asks more of the material than sheet can give.

Pressure vessels. Structural fabrication. Chemical process plant. Nuclear containment. Heavy cladding. Whatever the application, the grade, the form and the certification all matter.

We hold the plate grades and forms your project relies on.

Grades held in stock

1.4301/1.4307 (304/304L)

The everyday austenitic plate grade. Low carbon for improved weldability in thicker sections. Excellent corrosion resistance. The default for food, dairy, chemical and general fabrication.

1.4401/1.4404 (316/316L)

Molybdenum-added, low-carbon austenitic. Better chloride and pitting resistance. The 'L' variant offers low carbon for improved weldability in thicker sections. The choice for marine, chemical, pharmaceutical and offshore applications.

1.4003

Utility ferritic grade. Cost-effective plate where general durability and moderate corrosion resistance are enough.

1.4462 (2205 Duplex)

Duplex grade combining austenitic and ferritic structures. Roughly twice the yield strength of standard austenitic plate, with excellent resistance to chloride stress corrosion cracking. Used in oil and gas, chemical processing, desalination and heavy structural applications.

Forms we hold

  • Quarto Plate to BS EN 10088-2, ASTM A240 and ASME SA240, for larger sizes and heavier gauges
  • CPP (Continuously Produced Plate) to BS EN 10088-2, ASTM A240 and ASME SA240, for consistent supply and economical procurement
  • Cold Rolled & Descaled Plate to ASTM A240 and ASME SA240 in 304/304L and 316/316L, from 2mm to 6mm thick, for tighter tolerances and better surface finish
  • Treadplate for non-slip flooring and access applications

Non-standard sizes, specialist grades and thicker gauges are available to order through our worldwide supplier base.
