Our continuous cold Rolled screw flight  have good rigidity without welding line on the surface. We can manufacture the spirals with the outer diameter ranged from 90mm~600mm, inner diameter ranged from 25mm~350mm and blade thickness of 3.5mm, 5.0mm and 6.0mm.

Material: high quality carbon steel Q235

Manufactured by our special technology, our endless cold-rolled spirals have the following features compared to traditional spirals:
1. Good smooth finish, uniform shape and high precision. It's conducive to
material conveying, reduce the product damage, and to increase the transporting efficiency.
2. Easy installment, improve the work efficiency and reduce the production cost.
3. Under the physical and chemical surface treatment, the spirals enhances the
anti-rust property and improves the appearance of screw conveyors.
4. After cold rolling, the spirals will be hardened, which will enhance greatly
the rigidity and the wear-resistance, say by one time. The HB value is 240.
