{dede:global.cfg_gsname/} | Updated: 2020-01-19 03:22:09
Manhole covers are usually found in all corners of various cities. This type of manhole cover is used in all places where there are sewers. They are generally divided into round and square shapes. There are also known as rafters or cast iron rafters or rainwater rafters. Sewer manhole covers generally need to meet the following characteristics. The load-bearing condition is better. The second is to have good anti-theft properties. In case of loss, it is unthinkable. The third is to have good fixing performance. For example, it cannot be topped by rain or rain when it rains heavily. Washed away. Drainage manhole covers are generally provided for drainage in the city center when it rains, and are also called rainwater rafters or cast iron rafters. The material is generally cast iron with a gap in the middle to facilitate the smooth flow of water into the well. There is usually a row of strong sticks on the outside to block dirt or other debris.
Steel grate rainwater manhole covers are available in multiple models to suit different span loads and requirements. The material is usually Q235 or 304.
Light structure: The solid grid pressure welding structure makes it have high load-bearing. Uses: It is widely used in platforms, walkways, trestle bridges, trench covers, etc. in the fields of petrochemicals, power plants, water plants, sewage treatment plants, municipal engineering, environmental sanitation engineering, etc. Manhole covers, ladders, fences, guardrails, etc., common specifications are 20 * 5, 25 * 5, 25 * 3, 32 * 5, 32 * 5, 40 * 5, 40 * 3, 50 * 5, 65 * 5, 75 * 6, 100 * 8, 100 * 10 and so on.
Hot-dip zinc surface treatment makes it have quite good anti-corrosion ability and durable: Hot-dip zinc surface treatment makes it have pretty good anti-corrosion ability, easy to hoist and so on; its common specifications are 5 * 5, 6 * 6, 8 * 8mm, with beautiful surface gloss; good ventilation, lighting, heat dissipation, explosion-proof, non-slip performance; beautiful surface gloss; good ventilation, lighting, heat dissipation, explosion-proof, non-slip performance; anti-fouling, light structure, twisted square steel is made of disk It is made by drawing and twisting square moulds
Uses: Widely used in platforms, walkways, trestle, trench covers, manhole covers, ladders, fences, guardrails, etc. in the fields of petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, sanitation engineering, etc. Cover plate non-slip tooth profile and section I, steel grid plate (grid plate) Features and uses: Features: high strength, gutter cover cross bar: round steel made of Q235A or 304 stainless steel, twisted square steel, Ditch cover square steel or hexagonal steel,
Light structure: The solid grid pressure welding structure makes it have high load and easy lifting, etc .; beautiful appearance and high strength. It is recommended to choose standard sizes for design and construction. Our company can design and produce various sizes or other functions according to user requirements.
Features of rain cover:
1. Powerful anti-theft performance: The production of composite manhole cover manufacturers generally uses unsaturated resin, glass fiber and other materials to be compounded through a special production process. 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 formula, to ensure the penetration of composite manhole cover in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of 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 and changeable, harsh and demanding places. The manhole covers produced by Baist composite manhole cover manufacturers have been tested by the 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 logos 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 appearance and color that are the same as various stone pavements.
