10mm steel wire rod manufacturers | Dingding cold rolled | 10mm rebar rod provided by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) is a professional enterprise, "cold-rolled ribbed steel CRB550", the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Liu. Specified in the specification beams, columns ends stirrups to be encrypted, its purpose is to ensure that under seismic loads and vertical frame beam plastic hinge zone and column ends have sufficient shear capacity, while also increasing the stirrups of concrete constraint for 10mm rod rebar suppliers to ensure the realization of the beam hinge mechanism to ensure ductility column ends, to prevent buckling of longitudinal reinforcement. From watching these purposes, is to ask the stirrups sufficient number and density, in order to improve the shear capacity of beams bend ductility. Steel hooks. There are three forms, namely semi-hook, hook and straight oblique hook. After the steel bending, bend endothelial contraction, skin extending the length of the same axis, forming a circular bend, bent after cutting size larger than the size of 10mm rebar wire rod mill, consider bending adjustment value. Reinforced apex 2.5d 10mm diameter rebar rod manufacturers, flat part 3d. Steel hooks to increase the length of the theoretical value: to turn semicircle hook for 6.25d, for direct hook to 3.5d, for oblique hook for 4.9d.
