General Product Description

Polyester Indoor color coated steel from SSAB is available in a smooth surface and offers a wide range of colors and gloss options. 

It is used in e.g. ceilings, load-bearing profiles, doors, window frames, cabinets and interior walls. Polyester Indoor color coated steel is also used in products in metal fabrication and in claddings of the food industry.

Unless otherwise specified, the reverse side of the sheet is painted with a two-layer grey backside coating.

Polyester Indoor complies with current REACH regulations and is fully free of chromates.

SSAB’s color coated steels are all manufactured according to EN 10169.

Colors

Polyester Indoor color coated steel offers a wide range of colors and gloss levels. In special cases, the coating can be matched to customer's requirements.

Note for Metallic colors: To ensure tonal consistency of colors on a single exterior face, all material must come from the same production batch. Also the directionality of surfaces has to be consistent especially when sheets are cut to size.

Reverse Side Coating

Unless otherwise specified, the reverse side of the sheet is painted with a two-layer coating to further improve the corrosion resistance of the end product. The coating provides good adhesion properties to many adhesives and foams; nevertheless the compatibility needs to be tested case-specifically.

For easy material identification the reverse side of the sheet is stamped with the SSAB logo and the product name. The production date is marked to ease material traceability and can be referred to within the guarantee period. An arrow shows the direction of production to ensure installation in a uniform direction.

Protective Film

Temporary protective films are available for protection during processing and installation. Protective films are applied on the top side of the Product. Films will be centered to the strip meaning that typically there are small unprotected areas in both edges of the strip. Unprotected area may be cut away if customer so wishes. Joined film strip ends are marked with red tape on the edge of the product.

Products with protective film should be stored in dry and warm conditions, since the adhesion between protective film and color coating decreases both in high and low temperatures. Humidity changes also the adhesion properties and in worst case leaves the adhesive part of the film on the product surface.

Adhesion of protective film increases over time, eventually making it difficult to remove the film from the Product’s surface. Due to that, protective film is recommended to be removed from the material as soon as possible, but no later than six months from the manufacturing of the Product or after one month from the end product installation depending on which comes first.

Protective film decreases friction between coil windings, which creates a high risk of coil collapsing on thin gauge coils. Due to the risk of collapsing, SSAB does not recommend protective films for steel nominal thickness ≤ 0,60 mm. If protective film is essential, following precautions must be taken to minimize the risk of collapsing: Max coil weight < 5 tons and self-supporting coil protection shields must be used in the package.

Typical protective film thickness is around 45µm, max working temperature +80°C and max and min stripping temperatures +40°C & -10°C.

Protective film has a good resistance to forming but is susceptible to cuts. When working with material with a protective film, clean tools that do not damage the film, and appropriate methods are to be used. Cutting fluids are not needed because the film protects the material surface and reduces friction. Cutting fluids may also have negative impact on the protective film and its adhesion.

Protective films can be recycled as plastics, combusted or disposed via the municipal waste management system depending on the local waste management guidelines and regulations.
