The ditch cover plate is mainly used with the drainage ditch, and the material and thickness of the product affect the use effect and life of the product. The more common ditch cover materials on the market include cast iron, composite materials and glass fiber reinforced plastic, etc., below, let's explain these materials and thickness.
1. Cast iron ditch cover plate. Cast iron ditch cover plate is a common cover plate material, the surface of the product is attached to a layer of paint, which can effectively avoid oxidation and corrosion, and the thickness of the cover plate is generally 25mm, 30mm and 40mm, the cover plate of this material has high strength, high hardness, reliable performance, etc., and has good wear resistance and corrosion resistance.
2. a steel plate ditch cover plate. Generally speaking, the shape of the steel plate ditch cover plate is similar to the cast iron ditch cover plate, and this material will be lighter, because it is made of steel plate welding, so it will be somewhat different from the cast iron ditch cover plate in terms of appearance and weight. The thickness of the steel plate trench cover plate is generally 2mm, 3mm and 4mm, etc. The main characteristics of this product are high strength, light weight, and not easy to deform.
3. a composite ditch cover plate. The more common materials of the composite ditch cover plate are resin materials, carbon fiber reinforced plastics, etc., and have excellent corrosion resistance, and the thickness of the composite ditch cover plate is mainly 25mm, 30mm and 35mm. It has the advantages of light weight, anti-slip shock absorption, and not easy to deform.
4. FRP ditch cover plate. This kind of cover plate is mainly made of FRP and resin, this product has the advantages of light specific gravity, high strength, corrosion resistance, etc., and the service life of the product is relatively long, the thickness of the cover plate is generally 25mm, 30mm, 35mm, etc., mainly has the advantages of easy disassembly and assembly, no deformation, beautiful molding, etc.
