Welcome to inquire! Contact: Liu. Cold-rolled ribbed steel Advantages: Good rolled ribbed Bond properties between steel and concrete. So for members, essentially eliminate the anchorage zone cracking components, wire slippage and damage the phenomenon, and increase the carrying capacity and anti-cracking ability of member ends; reinforced concrete structures 8.5mm steel wire rod, crack width than light round 8.5mm steel rod rebar spot, even smaller than hot-rolled rebar. Cold-rolled ribbed steel (commonly known as cold rolled rebar) in recent years developed a new, highly efficient, energy-efficient buildings 8.5mm steel rod rebar suppliers, which in ordinary low-carbon or low-alloy rod rod , multi-channel cold-rolled or cold-drawn and a reducing indentation, the final form of reinforced with two or three sides of the crescent-shaped transverse surface ribs. Because of its high strength, good plasticity, strong bond (bond with concrete anchor capacity increased from 2 to 6 times), and thus have developed rapidly.
