CORRUGATED PROFILES

SOME TYPES OF COMMONLY USED CORRUGATED PROFILES:

Asbestos Cement Big Six Asbestos Cement Trafford Galvanised Iron Profile (G.I) Indal Profile (Aluminium Sheet) Tiger Steel Profile Metacolor Profile Interarch Profile Lloydeck Profile

APPLICATION AREAS:
As highlighted earlier, these Polycarbonate Corrugated Sheets are used principally in industrial applications which include Industrial skylights, Strip lighting and North light glazing. However, these corrugated roofing sheets may also be used in commercial buildings, infrastructural complexes and residential applications. Following are a few typical application areas:

Skylights in railway stations & bus stands Skylights for large warehouses Natural lighting for operational areas in airports, ports, cargo complexes etc. Terrace coverings, chajjas and private extensions. Green houses for critical cash crops, sensitive to climatic changes. Schools & educational institutions. Weather protection for aquaculture ponds. Bus Q shelters

These polycarbonate roofing sheets can be deployed to harness sunlight for a wide range of applications thereby reducting or eliminating the need for artificial lights during day time.

AVAILABILITY & DIMENSIONS OF CORRUGATED POLYCARBONATE SHEETS:
Polycarbonate corrugated sheets are available in matching profiles to most of the contemporary corrugated roofing sheets. The dimensions are generally governed by the customers requirements and hence we offer tailor-made solutions in terms of choosing the right product and the dimensions in which it is required for a particular application. An island skylight configuration would require polycarbonate corrugated sheets in dimensions identical to the corrugated roofing sheets. In strip-light & north-light configurations it may be varied as per recommendations of the Architect / Consulting Engineer. The maximum limit is subject to the process area limitation which can be upto 1100mm in width and a maximum of 4.270mm in length (14Feet).

New corrugated profile is rapidly being introduced to the industry by either existing players as part of their improvement and modernization plans or by new / emerging companies. Innovation has always been at the core of Flextituff Industries and we continue to strive towards providing user friendly solutions, within stipulated cost and time frames.
