Thick sheet cut to length line

Thick sheet cut to length line

The thick sheet cut to length line is generally used for jobs like uncoiling, straightening, measuring, cross-cutting to length and stacking of various materials such as cold or hot rolling carbon steel, tinplate, stainless steel, and other kinds of metal with coated surfaces.

Features of thick sheet Cut to Length Line:

1. Our cut to length line uses a roll feeding, AC servo drive.

2. It has a fully digital length control system that ensures fast positioning with little error.

3. It has a hard chrome plated surface and is durable and abrasion resistant.

4. It is used together with a hydraulic shear or an air-clutch shear to carry out fast shearing and convenient clearance adjustment.

5. Our cut to length line is suitable for hot rolling carbon steel, tinplate, stainless steel, and other kinds of metals with coated surfaces.
