High quality guardrail cap posts
Advantages
1. Light weight: the weight of nylon is only 1/7 of cast iron, so that it is easy to carry and install, greatly reduce the labor intensity of workers at the same time, but also can greatly reduce the "artificial" loss rate, in addition, because of the difference in materials, also reduce the heart of the criminals coveted. Therefore, the recycling reuse rate of nylon column shoes (column cap) is more than 50% higher than that of ordinary metal column shoes.
2. Corrosion resistance: especially in the downhole long-term humid environment, the corrosion resistance of nylon is far more than that of cast iron and wood. Practice has proved that the service life of nylon column shoes (column caps) is more than three times that of traditional column shoes.
3. Easy recovery: due to the thick pressure of the coal seam, the old column shoes often can not be recovered, causing waste to the economic benefits of coal mine, mining costs rise, the new nylon column shoes (cap), as long as slightly pull the recovery chain, you can pull out, the resistance is greatly reduced.
4. Good toughness: iron shoes and wooden column shoes, iron shoes pouring process is easy to produce trachoma, easy to break, the organization of wooden shoes is soft and easy to break, often can not be used reciprocately. Resulting in high mining costs. In short, the use of nylon column shoes (column cap) can effectively reduce operating costs, greatly improve the comprehensive benefits of enterprises.
