High accuracy, low material wastage; Smooth surface finish, good rigidty, easy to weld and assemble. 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.Should you feel interest in this products or other related product range, please don't hesitate to contact us.We have two types of helicoid flights:Type 1: Continuous/Endless Cold Rolled Screw FlightFeature: a continuous one-piece helical formed bar, to be cut at any length. They're formed on specialised forming equipment to precise diameter and pitch. Suitable for shaftless applications or to fit onto most pipe size. Size range: Outer diameter-----90mm~600mmInner diameter-----25mm~350mmBlade thickness------3mm, 3.5mm, 5mm, 6mmMaterial: now only mild carbon steel available.  Type 2: Sectional FlightFeature: individual turns cut from mild, stainless and abrasive resistant steels which are formed into a helix with the desired outside diameter, pitch and inside diameter to fit the specified size. Finished flight is the same thickness in the full cross section from ID to OD. Size range: Outer diameter-----100mm~1500mmInner diameter-----40mm~720mmBlade thickness------3mm~50mmMaterial: mild carbon steel, wear resistant steel and stainless steel.
