Trapezoidal Profile and Tiles

Profiled Sheets :-
These sheets are available in various thickness profiles, colours & sizes like steel cold rolled sheets and cold rolled steel strips. The pre-painted / plain / cold / hot rolled coils base material are loaded on hydraulically operated uncoiler. Then, with the help of pinch rollers, the open end of the coil is brought under the first set of rollers and the coil automatically moves through the various sets of rollers in the forming machine till the sheet takes the desire shape.

When sheet reaches final stage of forming, it is cut to the desired lengths with the help of hydraulically operated automatic cut- off machine. The speed of production & pressure on roller is controlled using computerized controls.

Tiled Sheets :-
The profiled round rib sheets is fed mechanically to the computer controlled tiling machine which is programmed to produce the tile shape at a pre determined pitch on the sheets.
