Rebar Shape size: Length and tolerance. Length. Steel is usually delivered by length, specific length of delivery should be specified in the contract. Length tolerance. Reinforced by the length of time of delivery shall not be greater than the allowable deviation of ± 25mm; when asked when the minimum length 10mm rebar manufacturers, the deviation is + 50mm; 10mm when asked when the maximum length of rebar, the deviation is -50mm. Bending and ends. Steel cut ends should be honest, should not affect the use of local deformation. Reinforcement of 8-50 mm nominal diameter 10mm rebar sales, recommended 8,12,16,20,25,32,40 mm diameter. Ribbed steel bars in concrete main tensile stress. Ribbed steel due to the role of the ribs, and concrete have greater bonding capacity, and thus better able to withstand external forces. Ribbed steel is widely used in a variety of building structures, especially for large, heavy, light and thin-walled high-rise building structures. 10mm 10mm rebar steel manufacturers _ _ Gansu cold-Ding Ding Ding Ding Industrial Co., Ltd., Henan Province by.
