The surface of the manhole cover is full of patterns, with crosses, herringbone, and other patterns. The pattern on the manhole cover is mainly used for anti-slip, and the surface of the manhole cover has a unique anti-slip pattern, mainly to increase friction and prevent rain, snow, The ice covered slipped pedestrians. If it is raining or snowing on a smooth iron plate, it is easy for pedestrians to slip on it. If an elderly person or a child is walking on top of it, the consequences are even more unthinkable. It is likely that as soon as a few ribs are broken, they will be severely killed. In addition, you can make different marks on the top, such as the manufacturer, contact information, and the affiliated units of the manhole cover. In some places, art manhole covers are also made. This depends on the poor use environment, such as making a community on the surface. Posters, etc.
Now on the market, various manhole covers produced by various Shandong composite manhole cover manufacturers use different materials, but several characteristics are similar:
1. Powerful anti-theft performance: Composite manhole cover manufacturers generally use unsaturated resin, glass fiber and other materials to compound materials through special production processes. After high-temperature grinding and pressing, the product has no recycling value. Extracting rebar is not so easy.
2. Service life: Through the use of high-performance resin, glass fiber and special production process formulas, the penetration of the composite manhole cover in glass fiber is ensured, and the adhesion between the two is greatly enhanced, so that the material is not affected by cyclic loading. Internal damage occurs, thereby ensuring the service life of the product and the same superiority of other resin composite manhole covers, effectively eliminating the disadvantages of poor adhesion.
3. High temperature / low temperature resistance, good insulation performance and strong corrosion resistance: the product is corrosion-resistant, non-toxic and harmless. No metal additives. Can be used in complex, changeable, harsh, and demanding places. The manhole covers produced by Baist composite manhole cover manufacturers have been tested by relevant national authoritative testing agencies, and have obvious acid and alkali resistance, corrosion resistance, anti-aging and other indicators have reached product quality specifications.
4. Beautiful and practical, high-grade: According to the needs of high-end customers, we can make personalized logos with complex LOGO and multiple colors on the same manhole appearance, making the patterns delicate, bright and clear. According to customer requirements, we can make all kinds of imitation stone with the same appearance and color.
5. Strong carrying capacity: the bottom adopts a special design structure, and the continuous reinforcing fiber filaments used are all made from the material to ensure that the fiber filaments and glass fiber cloth are integrated into one, so that the product has a certain carrying capacity.
6.Environmental protection, non-slip, low noise: the manhole cover does not slip after the car is rolled, there is no reverse ear noise and pollution.
