Our Product Range Includes:
• Iron roof sheetings in two main materials, namely in zincalume and aluminium.
• Metallic structures - Cee and Zed purlins.
• All finishing accessories including screws, washers etc..
Zincalume
Zincalume is a coating of zinc and aluminum, which gives much superior resistance against corrosion as compared to galvanized iron. It adapts itself perfectly to the Mauritian climate and offers an excellent resistance to corrosion.
Furthermore, it is covered with a layer of primer of +- 7 microns and with a layer of paint going up to +- 25 microns.
Aluminium - Reynolux
We have established a partnership with ALCOA, the world’s leading aluminum producer. Reynolux differentiates itself by certain characteristics, making it the product ‘par excellence’ for constructions in coastal areas.
It is covered by a paint coat developed by Alcoa, the Duragloss 5000. The technical properties of DG 5000 are identical and even superior in comparison to the PVDF base paint. Its most striking properties are its resistance to abrasion, salt, humidity and to ultraviolet radiation. Aluminum products can give guarantee up to 15 years.
We provide a wide range of colours in both materials and are able to provide any colour for large projects. Our sheets are the largest available on the market as they have an effective width of 1000mm for the IBR panels and an effective width of 900mm for the corrugated panels.
The advantages of large sheets are:
• Ease in the handling of material as less sheets are necessary for area coverage.
• Time effectiveness.
• Better aesthetic appearance as less sheets are fixed against one another.

Profiles
Our profiles can be distiguished by their width. They are the largest profiles on the market, which means fewer sheets will be used to cover your surfaces.
Support
Whether you want to apply your iron sheets on metallic structures or timber structures (frames), Grewals offers you the solution. For a metallic structure, Grewals offers you the Galvanised steel purlins in either Cee or Zed format, available in any (several) dimensions.
Fixtures
Grewals is able to offer you a complete solution regarding your fixing accessories. Our offer includes the self drilling screws for application of your sheets on metallic structures and coach screws (tirefonds) for application on wooden structures to the plastic ‘malakoffs’ through the sealing washers.
Other finishing accessories
Finishing accessories including valleys, Ridge Cappings, and flashings are available up to 4 meters long and can be bent in different angles as requested by our customers.
On top of that, we also bend already profiled sheets (Bull nose) up to 90 degrees.
Do's
1. Metallic particles (after installation) should never be left on the iron sheets.
2. Regularly clean your iron sheets simply with water.
3. Avoid the accumulation of leaves and branches on your roof and in the gutters.
Dont's
1. Never use solvent on the iron sheets.
2. Never use metallic brushes, or other metallic materials which can damage the paint coating.
3. Never walk on the zones where there are no purlins, as much as possible.
Other finishing accessories
• An average of 5 screws per m² of iron sheeting must be considered.
• We recommend inox screws to be applied on aluminum iron sheetings in order to guarantee a better compatibility between the two materials.
