The stainless steel grating drain cover is a steel product welded with flat steel into a square grid or plane in the middle. The one with surface galvanizing treatment is called a galvanized steel cover. The steel cover is made of carbon steel, and the surface is galvanized to prevent oxidation.
For the polymer concrete drainage ditch,the material polymer concrete is composed of synthetic resin, filler, and sand. When mixing, we add hardener and accelerator, and then fill it into the mould. After a few minutes of vibrating, the mould can be demolded to obtain the finished polymer concrete precast products. The difference between polymer concrete components and regular concrete is that the cementing material used is synthetic resin, not cement, but its technical performance is much better than ordinary cement. Compared with cement concrete, it has high hardness, high strength and significant performance of permeability resistance, corrosion resistance, abrasion resistance, freeze-thaw resistance and bonding properties.
