Spot steel plate, screw | Dingding cold rolled (certified) | plate, screw steel 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. Stirrups applications: frame structure under seismic action effects, beams, columns have a greater bending deformation, but the shear deformation is much smaller than the bending deformation, so when the beam column reinforcement for portrait subject require the reinforced plastic should be more important than the plastic stirrups requirements. That requires longitudinal reinforcement elongation should be larger than the stirrups. Since the provisions in the specification Ⅲ grade steel suitable for use as longitudinal reinforcement. Cold-rolled ribbed steel bars used as stirrups, when able to meet its plastic beams, shear deformation of the requirements of the column. Steel plate, screw steel wholesale manufacture, steel plate, screw steel surfaces should be clean shelf, adhesion of the oil, must be clean before the dirt, rust using rust can be combined with cold drawing process. Bar Straightening plate, screw steel, mechanical or manual available for straightening. After Bar Straightening prohibited after local bending, bending die, little wavy plate, screw steel manufacturing plant, its superficial injuries should not be reduced by 5% reinforced section. Reinforced steel cutting should be based on number, diameter, length and number, the length of match, first off a long break after a short feed material, minimize and shorten the steel short head, in order to save steel.
