A conservative architectural service-life position; the Chrysler Building’s stainless-steel roof, installed in 1930, remains a documented long-service reference. Exact life depends on grade, coating, exposure and detailing.
Discuss a project Material detail · Tin-coated and specialist stainless
Strength with a quieter surface.
Tin-coated stainless can mature towards the muted grey character associated with traditional sheet-metal roofs, while offering low weight and little scrap value. Decorative stainless is a separate design family and should be specified by exact grade and finish.

Important
All on-screen colours are illustrative. Current manufacturer literature and a physical sample govern the final selection.
Warranty terms differ by manufacturer, product, grade and application. Use the current written terms for the selected UGINOX, Roofinox or specialist stainless-steel system.
Tin-coated products lose initial brightness over time; pace and evenness depend on exposure and orientation.
Specification lens
Separate heritage intent from product shorthand.
‘Terne-coated’ is often used loosely. The specification should name the modern product, coating, stainless grade and approved details—not rely on a historical label.
Strong fit
- Churches and heritage roofs where lead theft, weight or budget is a concern.
- Durable roofs, flashings and details needing strength at low thickness.
- Selected façades or features where a precise specialist stainless finish is intended.
Resolve before selection
- Which grade is suitable for the coastal, industrial or rural exposure?
- Has conservation or planning approval accepted the proposed lead-replacement appearance?
- Are soldering, isolation, protective film and patination expectations documented?
Manufacturer finish library
Compare named products—then verify them in the hand.
These are manufacturer families, not Copperclad-created colour names. The chips orient the conversation; an official current sample remains the decision tool.
UGINOX Patina
Aperam
UGINOX Patina is tin-coated stainless steel for roofs, gutters and façades. Its initial metallic surface gradually develops a matt grey patina; K41 and K44 are different ferritic grades selected to suit the environment.
UGINOX Patina K41Tin-coated matt finish; grade subject to exposure
UGINOX Patina K44Tin-coated finish for different environmental conditions
Selection noteK41 and K44 are grade choices, not two decorative colours. The correct grade must follow the manufacturer's environmental compatibility guidance.
TIN
Roofinox
Roofinox TIN is a modern lead-free, pure-tin-coated stainless roofing surface often described in the terne tradition. The finish is intended to patinate towards a muted grey appearance.

Selection noteConfirm UK availability, exact grade, environmental suitability, soldering method and written warranty for each project.
Specialist architectural finishes
Rimex Metals
Rimex produces patterned, textured, coloured, embossed and other specialist stainless finishes. These serve a different brief from tin-coated roofing and require an exact finish reference before they are shown as a Copperclad offering.

Patterned stainlessSpecify the exact Rimex pattern
Coloured stainlessSpecify colour, process and application
Selection noteSpecify the exact Rimex finish, exterior application and performance requirements before samples are selected. Decorative Rimex finishes are not a substitute for a tin-coated roofing system.
Material consultation
Discuss the project. Then request the right samples.
Tell us whether the priority is a lead-replacement roof, a muted contemporary envelope or a decorative stainless feature. We will identify the relevant product family and arrange meaningful samples for a qualified project.
