Strenghtened construction of the cover permits for a fivefold resistance to pressure.
- Highest Quality all Karmat covers are produced with an A15 rating from the highest quality polimers resistant to high and low temperatures.
- Substantially increased resistance to pressure confirmed by independent laboratory testing
- The used UV stabilizer greatly increases the resistance of the cover against atmospheric factors and preserves their intensive color
- all screws and bolts used in the Karmat covers are made of corrosion resistant chromium-nickel
- a special anti-skid pattern was designed on the surface of the cover - the pattern is copyrighted in the Pattent Office
