Key Benefits

 

 

Prevents water build up

Due to the unique shape, corrugated roof sheets help water run downwards and keeps your roof top clear.

Durable

A corrugated roof sheet that is made from metals like steel or aluminium lasts for years and needs very little maintenance apart from a coat of paint occasionally.

Lightweight

Apart from being durable, these sheets are also lightweight making it easier to handle and install. It also does not increase the weight of the building structure.

Withstand weather conditions

Equipped to survive all weather conditions, corrugated sheets provide a protective barrier to your establishments and never rusts.

Rot resistant

Unlike most roofing material, corrugated metal roof sheets do not rot. Most metal sheets are also protected with a layer of chemicals to stop the formation of algae.

 

Galv. corrugated sheets application

 

 

Galvanised Corrugated Sheeting is a traditional profile often used on roofing and side cladding.
● This thick galvanised single skin corrugated sheet has many uses in commercial, domestic, industrial and agricultural buildings and can be used simply as a single skin of corrugated cladding.
● To over clad an existing roof or as part of an insulated build-up system

 

How much should corrugated roofing sheets overlap?

 

 

Residential garages

For a standard garage with a flat slope roof, basic overlap of 2 corrugations is sufficient to ensure there is no leakage through the joints.

 

Industrial warehouses

Since the roof span wider areas in large structures, an extra coverage overlap of 15 to 24 inches is recommended, to withstand large volumes of water.

 

Agricultural buildings

Here too, a basic 2 inch overlap will work, especially for small barns and agricultural settings, though it is recommended to add an additional layer of sealant for waterproofing.

 

 

 

QUALITY INSPECTION

All goods will be inspected after finishing manufacture, a series of tests will be carried out, such as

1) Thickness test;

2) Width test;

3) Zinc coating test;( including both Physical Detection & Chemical Detection)

4) Hardness test,

5) Tensile Yield Strength test.

We ensure that all products confirm to the requirements of the order and relevant international standards.
