Cold-rolled ribbed steel bars in the middle floor of strong substitution Ⅰ grade steel, the original design of the cracks if they meet the requirements, then after substitution certainly can meet the requirements, do not go checking, of course, this other strong substitution must meet the minimum reinforcement ratio requirements. Floor slab, roof and distribution of reinforcement bars. Bar diameter is generally 5─10mm, floor slab stiffness due to generally higher, if the cold-rolled ribbed steel substitution Ⅰ grade steel plate, screw steel time quotes, generally only other strong wholesale substitution of steel plate, screw, do not make The width of crack. Cold-rolled ribbed steel bars welded mesh, especially for highway pavement, airport runways, large diameter sewer, drainage tunnels. Cold-rolled ribbed steel bars in overseas mostly in the form of mesh. Our industry standard "welded steel technical specification for concrete structures" JGJ / T114─97 been implemented. With the improvement of the level of industrialization of construction, welded steel applications will be gradually increased. Plate, screw steel pricing, plate, screw steel, cold-rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province.
