Steel specification: the distance between the end joints bend steel not less than 10 times the starting point of the bar diameter. Construction steel tensile force can not tell, the pressure of 7.5mm cold-rolled straight rebar spot, pull the handle to accept. Reinforced joints transverse spacing of not less than the bar diameter. Welded steel welders must engage after passing the examination certificates. Former steel welding, weld test must be carried out according to the construction conditions. 7.5mm cold rolled steel welded before each batch straight rebar procurement, welding processes and parameters should be selected trial welding, weld quality standards after the trial 7.5mm cold-rolled strip steel production plant directly before it is welded . Mechanical properties of steel: the mechanical properties of steel are mainly tensile, cold, toughness and fatigue resistance, etc., tensile properties also include the yield point, tensile strength and elongation. Different manufacturers, different specifications of steel should be tested in batches according to the current regulations of the State of reinforced inspection, inspection of steel only for processing. Unknown number of reinforced steel, subject to inspection can be processed using the rear. 7.5mm cold-rolled straight rebar prices | cold rolled steel straight | Ding Ding Ding Ding cold rolled by Industrial Co., Ltd., Henan Province.
