Wide choice to meet your needs

We offer a wide choice of tin-free steel – tailoring our products to meet your required strength, surface finish and forming requirements. Our foodsafe ECCS packaging material is produced using Tata Steel’s blackplate.

Bespoke tempering and investment in both batch and continuous annealing ensure that we can match requirements for a variety of applications.

We supply tin-free packaging steel in a choice of:

  • single reduced and double reduced steel grades – with material tempered to match your strength and ductility requirements
  • thickness (gauge) – with scope for downgauging thanks to our direct rolling operations which produce thin-gauge material with increased strength
  • surface finish – to meet your processing needs and product performance requirements
  • width - up to 1050mm but with extra-wide (1200mm) material under development for optimised operational flexibility and output
  • oils – for protection in transit


Reliable quality for efficient canmaking and product performance

We have a proven track record in ECCS manufacture. Our fully-traceable tin-free products benefit from the dependable quality of our blackplate feedstock and ongoing investment at our dedicated packaging steel mills.

All of our processes – from initial pickling, through rolling, annealing, tempering and chromium coating – are carefully controlled and monitored. Process control is combined with rigorous inspection to deliver:

  • reliable mechanical properties – including earing properties required for 2-piece drawn can production
  • consistently good shape and dimensional tolerances – for efficient processing
  • precise surface coating chemistry – for reliable lacquering
  • homogenous coating coverage – for corrosion resistance (although ECCS is not suitable for highly acidic can contents)
  • excellent surface finish – at a roughness to match your requirement and achieved through careful control of both direct and temper mill rolling


New tin-free steel development for REACH compliance

TCCT? (trivalent chromium-coating technology) is a sustainable, reliable replacement for conventional tin-free packaging steel. Developed by Tata Steel, TCCT complies with European REACH (Registration, Evaluation, Authorisation and restriction of CHemicals) regulations which ban the use of hexavalent chromium in electrolytic chromium coated steel (ECCS) manufacture.

Food-safe and suitable for a wide range of packaging applications, TCCT enables fast, repeatable processing. It is available in widths up to 1200mm for output optimisation. Key features include:

  • reliable mechanical properties – including earing properties required for 2-piece drawn can production
  • consistently good shape and dimensional tolerances – for efficient processing
  • homogeneous coating – ensuring reliable lacquering and corrosion resistance
  • excellent surface finish – at a roughness to match your requirement


Responsive service to suit your production demands

Our flexible, multi-site operations and robust supply chain infrastructure mean we can offer short lead times (as little as two weeks) to suit your production demands.

Packaging steel can be supplied in:

  • coil or sheets
  • DOS or ATBC oil

Our approachable ECCS experts are happy to advise you on the best products to meet your needs. Please contact us to discuss your requirements.
