High ductility cold-rolled ribbed steel equipment
High ductility cold-rolled ribbed steel equipment is a new type of high-efficiency and energy-saving steel widely used in industry, construction, highways, Bridges, subways, DAMS and other industries, also known as cold-rolled threaded steel. Its points are mainly reflected in the following five aspects;
1. the intensity is high. Its tensile strength is 1-2 times that of hot rolled steel bars,
2.its plasticity is good. Generally, the elongation of steel bars after cold drawing is 2.5%, while the high ductility cold-rolled ribbed steel bars are as high as 4% or even 8%.
3.double the grip. The anchoring capacity with concrete is increased by 3 to 7 times, and it is a more commonly used building material.
4.the concrete pouring operation can be carried out on the construction site to improve the operation efficiency by 50%;
5.high ductility cold-rolled ribbed steel bars can produce small specifications of threaded steel bars, more complete specifications.
