The rainwater grate is made of welded flat steel and twisted square steel or flat steel and flat steel. Rainwater grate has the advantages of beautiful appearance, good drainage, high strength, more specification and low cost, so the steel grid plate rainwater grate is usually used.
With the development of technology using resin or plastic reinforcement reinforced inorganic filler to form a new composite water grate. Rain grate has very strict standards in the production process, and the product quality is well guaranteed. At the same time, it also costs for a very reasonable product. During use, by welding process and connecting other functions, reduce production costs. The product is treated with a galvanized appearance, but damage cannot be avoided over time. To prevent damage to the product, we should pay attention to the product maintenance.The reason for the product damage is the change of the specifications after the long-term use of the product, resulting in the insufficient structural bearing capacity. And its structure will cause the deformation defects of the product by various accidents, resulting in the weakening of the component section and the cracking of the joints.Under the temperature difference, the structure or connections crack.
One layer of the rainwater grate surface is an abrasion resistant layer, which is made of anti-aging, acid, alkali and UV resistant unsaturated polyester epoxy resin adhesive and artificial synthetic steel jade sand in 80~120 order.Using artificial synthetic steel jade sand, iron powder, diamond sand, etc., with high wear resistance, and using epoxy powder fine sand, to make the nodular cast iron grate has the ideal wear resistance performance. Because diamond sand, steel jade sand is a raw material for grinding wheels, sand paper, they are more wear than raw iron.
Five characteristics of rainwater grate
Rainwater grate will generally have some characteristics, with these characteristics suitable for our use can be considered a qualified product, the following for you to introduce the qualified rainwater nodular cast iron grate should have five characteristics.
1. anti-sinking function: the design cleverly connects the well ring manhole cover together, so that the force of the manhole cover is evenly dispersed into the whole highway, so as to effectively resolve the power of downward pressure.
2. self-regulation function, the complete name is the self-regulation type settlement prevention manhole cover, which can automatically adjust the height of the manhole cover according to the downward pressure force of the manhole cover.
3. anti-theft function: the manhole cover cannot be opened without a special key from the outside.
4. anti-shift function, not only the sinking is effectively controlled, but also the left and right displacement.
5. noise prevention function, regardless of how many years, after the wheel rolling will not make a little noise.
