1. Structure:
Using the structure of pot bottom style (loading equally),other than the one of ribbing style (loading centrally),the strength supporting area will extend by more than ten or dozens of times. Therefore, the ability of strength sustaining will be more excellent.
2. Materials:
♥- Our Burglarproof Artistic manhole covers (shorted for GRP manhole cover) are made from composite materials such as glass fiber, resin, quartz, corundum etc..
♥- Applying wear-resistant and climate-resistant materials on the relief sculpture layer so that the products can be long-term used under different environment.
♥- Applying continuous reinforced fiber on the structure layer to ensure the products having sufficient sustaining ability. While some of other composite material manhole covers.
3. Design:
Infusing the manhole covers with the art of relief sculpture, designing individually to meet clients demands with artistic effect, promoting the culture feeling of our composite material manhole cover, the material is FRP, shorted for Fiber Reinforced Plastic
1.Anti-theft:
The anti-theft manhole cover is mainly to prevent thieves from stealing the manhole cover and avoid pedestrian accidents. It mainly adopts six different kinds of anti-theft methods: first: iron chain connection method; second: with hinge; third: anti-rotation technique, fourth: the bolt-blocking technique; fifth: the lock key method; sixth: the fork joint linkage
2.anti-sound
Anti-sounding is mainly to prevent the car and pedestrian fire objects from escaping when they pass.
3.anti-jump
A flexible cir-clip is added between the manhole cover and the manhole cover to fix the manhole cover on the well ring, thus solving the problem of the manhole cover jumping.
4. fall prevention
The manhole cover and the well ring are connected together by folds, so that the problem of fall prevention is well solved.
5.anti-displacement
