Overview

To meet your application and processing requirements, we offer reliable ECCS packaging steel in a wide choice of grades, thickness, surface finish and width

Our electrolytic chromium coated steel (ECCS) for packaging is well-proven in a range of applications. Providing an excellent substrate for lacquering, this tin-free steel is available in a wide choice of grades, thickness and surface finish to suit your processes and applications.

To ensure compliance with upcoming European legislation, we have developed a sustainable, replacement for conventional tin-free packaging steel, TCCT, available from Tata Steel Nederland. Find out more about TCCT here .

Packaging and related applications for our tin-free steel include:

easy-open ends
classic (standard) ends
twist-off caps
2-piece DRD
speciality packaging
microwaveable cans
bakeware

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 1070mm
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

Responsive service to suit your production demands

Our flexible, multi-site operations and robust supply chain infrastructure mean we can offer short lead times 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.
