Cold-rolled ribbed steel bars after use Hot rolled steel (wire rod or straight) through 6.5mm cold-rolled strip light reducing rod rebar spot, rolled rib and eliminate stress into a new and efficient reinforcement. In LL550 cold-rolled ribbed steel reinforcement substitution level I can save more than 35% of steel; with LL650 and LL800 cold-rolled ribbed steel cold Roberts replaced with small prestressed 6.5mm cold-rolled steel wire rod procurement can improve member ductility and impact resistance. Cold-rolled ribbed steel structure design elements: concrete strength selection. For reinforced concrete structures in a class environment, the concrete strength grade of not less than C20, for in two, three environmental reinforced concrete members strip cold-rolled steel plate, the concrete strength grade not less than C30; for kitchen , bathrooms and other damp indoor environment sector, due to its small size plates, such as its strength grade concrete below C30, CRB550 grade steel can not be directly used HPB235 grade steel. 6.5mm cold-rolled steel wire rod price _ _ Jiangsu Dingding cold rolled strip cold-rolled steel plate provided by Ding Ding Industrial Co., Ltd., Henan Province.
