Protective coatings
The paint coating protects the sheet from weather and knocks, and gives the colour. Warranty length depends on the coating, not the steel. Colour on screen is always approximate - we send a sample before you order.
Four groups
-
Up to 30 years
Basic polyester
Gloss polyester PS25 and metallic PS25. UV resistance to RUV4 (EN 10169). For when price and a wide colour range matter most.
- PS25 - gloss, 25 µm
- PS25 metallic
-
Up to 35 years
Advanced polyester
Thicker matt polyester. Same RUV4 class, thicker film. For houses this group is usually enough.
- TOPMAT® 35 µm
- PMG35®
- ULTRAMAT®
-
Up to 50 years
Polyurethane
A 50 µm film holds corrosion better in towns and industry than polyester. Technical warranty - up to 50 years, aesthetic - up to 30.

Care
Any coating lasts longer if you inspect and wash the roof once a year.
- Inspection - once a year, preferably in spring.
- Washing - a soft brush and water up to 60 °C. A mild detergent (pH 6-7) is allowed.
- Pressure washer - max 100 bar, no closer than 30 cm, not square-on to joints.
- Do not use: scouring powder, nitro solvents, chlorine, ammonium chloride.
- Repairs during the warranty only with the installer's written consent and the right paint.
A repaired spot may differ from the next sheet - varnish ages in UV. Work-safety rules apply throughout.
