Construction Points cold-rolled ribbed steel bars: cold-rolled ribbed steel stacking. Cold-rolled ribbed steel bars should be timely approach, CRB550 steel sales, yard must sclerosis, drainage flow, CRB550 steel, open storage time not too long, to avoid excessive corrosion. Should be steel, grade, size and length of different stacked separately, CRB550 rebar spot prices, 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. Construction Points cold-rolled ribbed steel bars: cold-rolled ribbed steel processing. After straightening machine straightening of steel, the surface may not have obvious scratches; reinforced straight after should have a local bent, straight bars per meter and the total length should not exceed four thousandths of curvature. Tolerance cold rolled ribbed steel processing: Length of the reinforced ± 10mm, inner stirrup net size ± 5mm.
