Construction Points cold-rolled ribbed steel bars: cold-rolled ribbed steel stacking. Cold-rolled ribbed steel bars should be timely approach, yard must sclerosis, drainage flow, cold-rolled steel wire rod company, open storage time not too long, to avoid excessive corrosion. Should be steel, grade, size and length of different stacked separately, cold-rolled steel wire rod, take a head together, set clear signs. Check the design files: mainly check design drawings, design documents review comments, the original design units issued reinforced substitution lists. Cold-rolled ribbed steel Technical requirements: Grades and chemical composition. Manufacture of steel wire rod should be consistent with GB / T 701, GB / T 4354 or other relevant standards. Delivery status: reinforced by cold delivery. Low-temperature tempering allow cold rolling. Mechanical properties and process performance: When bending test by bending parts of the surface can not crack.
