Cold-rolled ribbed steel production equipment: cold-rolled ribbed steel production equipment based on the number of rolls in two and three-roll-shaped roll shape. Three-roll mill capable of rolling active high strength (1500MPa) 9.5mm cold-rolled steel spot straight, large diameter (ФR12) cold-rolled ribbed steel bars. Because it does not depend on the tractor, but by direct income roll raw materials, so its raw materials and finished products can be either rod can also be straight. Cold-rolled ribbed steel construction elements: randomly selected from each batch of steel two specimens, a tensile test, do a straight cold-rolled steel bending test, the test results should be consistent with the tensile strength. When one of the indicators do not meet the above requirements, should be reinforced batch fetch double the number of samples to be retested, there is still a specimen fails the retest, the judge failed batch of steel, the construction site should be cleared . 9.5mm cold-rolled strip steel factory direct | Dingding cold rolled | Shandong cold-rolled strip steel straight by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
