1. Manufactured to EN 1433:2002.
Grates-Steel or cast iron
3. The advantage
A. Good compressive strength and flexural strength
Compressive stregth and flexural strength are 2-3 times of nondescript cement.
B. Acid and alkali resistance ,corrosion resistance.
The acid and alkali resistance can be up to PH1-10. Such as the snow-dissolving agents, has no effect on the drainage channel.
C. Smooth surface, maintenance free
The surface is smooth and dense,roughness coefficient is small. It's not easy to heap up sediment, self-purification, maintenance free.
D. Anti-freeze, penetration-resistance
The alternate freezing and thawing will reduce the property of cement , but have a small effect on polymer concrete. Because whining the polymer concrete, without the structure of water-absorption and water-desorption, permeability is 0, Thousands of testing prove this good quality.
The durable years of polymer concrete is longer than the cement concrete or other materials, almost without time limit
4. Application range: Square, station, parking lot , street, pedestrian zone, stadium, airport, park, exhibition hall, etc.
