Product Description
The steel strand composite interface is welded at high temperature, the surface copper layer is higher than 0.254mm, there is no residue, and the joint surface will not show corrosion; the surface copper layer is thick (the average thickness is more than 0.4mm) ; it has strong corrosion resistance, long service life(more than 40 years ) and reduce the maintenance labor intensity.
The steel strand is produced by cold rolling and hot drawing to complete the metallurgical fusion between copper and steel. Then ensure the perfect combination of copper layer and steel layer, which can be drawn arbitrarily like drawing a single metal.
Our company produce prestressed concrete steel strand, production strength level up to 1860MPa diameter up to 28.6mm, and supporting mature testing equipment.
