Product Description
Description
This production line mainly rolls diameter of 3.5—13mm and ordinary low carbon tray bar or low alloy tray bar with multiple cold rolling and a ribbing rolling, which finally forms reinforcing steel with three-side crescent shape ribs. It's widely applicable to highway, airport, irrigation works, city planning and construction engineering.
