Trapezoidal Profile and Tiles
Profiled Sheets :-
These sheets are available in various thickness profiles, colours &
sizes. 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.
