crash barrierIt is a typical cold-formed steel product with advantages such as good impact resistance, low cost, long service life, higher safety, and green environmental protection. The width of the fence board is 310mm, and the thickness is 3MM and 4MM. One ton of guardrail board can be laid: 80 meters for 3mm thick and 61 meters for 4Mm thick. Each kilometer weighs 12.3 tons with a thickness of 3MM and 16.388 tons with a thickness of 4MM.
The current highway guardrail panels are usually made of galvanized steel plates, which causes problems including:
1. Steel plates are prone to oxidation and rusting;
2. Easy to scratch the car;
3. The production cost is relatively high;
4. Light impact force can easily cause deformation of guardrails;
5. The production process is prone to pollution.
crash barrierIts characteristic is that the board body is made of high molecular weight PVC material, which does not require anti-corrosion, spraying and other treatments in production, truly achieving green environmental protection. At the same time, due to the significantly lower cost of PVC material compared to steel, its overall cost is low; The mechanical structure of the guardrail board is M-shaped, with reinforcement holes parallel to the direction of the board in the board body. Glass fiber is hot-melt coated in the reinforcement holes as reinforcement ribs. At the same time, two rows of reinforcement holes and reinforcement ribs are set at the protruding part of the board body to enhance the impact resistance strength.
