Cold-rolled ribbed steel intensity level roughly the same countries, both in the upper and lower cold-drawn steel ribbed 550Mpa manufacturers specifications 4─9mm. For ordinary reinforced concrete structures, such as pouring the slab, foundation slab of muscle force and distribution muscle, muscle building shear distribution ribbed cold drawn steel bars, beams, etc. stirrups. Mechanical properties of reinforced international standards ISO10544─1992 (E) provides as follows: yield strength 500Mpa ribbed cold-drawn steel, tensile strength 550Mpa, elongation (gauge 5 times the diameter) of 12% (Note: The extension of the set δ10≥ 8% rate instead δ5≥12%). The new cold-finished production line equipment went into operation in 2008 in Anyang, the corresponding national standard GB13788-2008 also released at this time. The new cold-rolled ribbed steel cold-rolled ribbed steel unlike in the past, the new production line has tempered steel cold drawn steel ribbed supplier, the product strength, ductility and yield point have increased. The new production line factory steel, its strength has reached 550MPa. Construction with ribbed steel cold drawn, cold drawn steel ribbed Jiangxi, Henan Province, Ding Ding Ding Ding Industrial Co., Ltd. provided by.
