Cold rolled ribbed bar with LZ carbide three dimensional rolls roll, which rib accuracy and mark clear, at same time to improve the performance of steel, enhance the strength. It makes sure that the quantity of a rolling reach to 800-1500 tons. Carbide rolls can be repaired repeatedly, and greatly reduces the production cost, significantly improves the efficiency.
Recommended Grade: LZ30/LZ40
