Hebei ted steel processing co., LTD., founded in 2011, the specialty is engaged in the steel bar welded mesh production and distribution, covers an area of 108 mu.In May 2012 by the Chinese steel structure association mat reinforcement branch absorption into the member.
Cold rolled ribbed steel bar is one of my company product, is introduced in detail as follows:
Cold-rolled ribbed steel grades by the CRB and reinforced the tensile strength of the minimum.C, R, B respectively (Cold - rolled), cold-rolled Ribbed (Ribbed), steel bar (Bars) the first three words of the English alphabet.Cold rolled ribbed steel bar was divided into CRB550, CRB650, CRB800, CRB970 and CRB1170 five grades.CRB550 for ordinary reinforced concrete with steel, other brand for prestressed concrete reinforcing steel bar.
Cold rolled ribbed bar has the following advantages:


1, high strength steel, can save material and reduce the project cost.Grade LL550 cold rolled ribbed steel bar compared with hot rolled round steel, used in cast-in-place structure (especially LouWu cover) can save 35% 40% ─ of steel.Such as considering no hook, steel more savings.According to the steel market price, each using a ton of cold rolled ribbed steel bar, can cut down the cost of steel 800 yuan.


2, cold-rolled ribbed the bond anchorage between reinforcement and concrete performance is good.Used in components, therefore, fundamentally eliminate the anchorage zone of cracking, steel wire slip and failure phenomenon, and improves the end bearing capacity and crack resistance of the component;In reinforced concrete structure, the crack width is better than a light round bar, even smaller than hot rolled reinforced bar.


3, elongation than the same kind of cold steel cold rolled ribbed bar.
