This kind of bolt adopts hot-dip galvanizing method. It forms a zinc oxide diaphragm or zinc hydroxide diaphragm on the surface of anchor bar, plate, nut and drill. It not only has anti-corrosion feature, but also is beautiful.
1. The roads’ slope supporting and reinforcement of coal and metal mine.
2. The surrounding rock support of roadway and well-bore during military engineering.
3. The foundation support in chemical equipment.
4. The reinforcement in special conditions.
1. Good resistance to corrosion, environmental and nuisance-free, the property of products is stable.
2. The adhesion between zinc oxide diaphragm and products’ surface is strong.
3. Enduring and durable, has longer life than common products.
