WR-01: Cold-rolled plain rebar
The application of steel reinforcing bar in masonry construction can be traced back dates to the 15th century. With high tensile strength and bonding capacity with concrete, steel bar has long been used as embedding reinforcement of concrete. That is, reinforced concrete as we know it. Steel as raw material, processed into different forms and sizes of steel reinforcing bars by different processes. They were applied to different parts of the building structures, to play the role of tensile, anti-pressure and reinforcement.
