Guidelines for our valued consumers:
We believe in customer satisfaction. We would like to thank you for trusting us and our services. Being a pioneer company it is our responsibility to provide you the best and guide you by our decades of experience. Kindly invest a few minutes of your time at the below mentioned instructions/guidelines for the betterment of your asset (Color coated Roofing Sheet).
Guard Film Removal
We advice our valued customers to remove guard film while installation of roofing sheets else moisture gets in and later onwards leads to colour peel off.
Protection from water/moisture ingress
Rain water or condensation is easily drawn between the surfaces of stacked sheets or they can be driven in by wind. The trapped moisture cannot evaporate easily so it can cause deterioration of the coating which may lead to reduced life expectancy or poor
Stack the sheets neatly and clear above the ground
If the materials are not required for immediate use, stack them neatly and clear above the ground. If left open, protect them with water proof covers.
Don’t let the stacked sheets get wet
If stacked or bundled roof sheet becomes wet, separate it without delay, wipe the sheets with a clean dry cloth and stack them separately to allow drying thoroughly.
If possible always stack uncovered sheets indoor and away from opening to outside.
We recommend you to use the materials immediately after purchasing to avoid storage problems
Avoid primer damage of the sheets with the help of a crane
If you have a crane available in your ongoing project site, use the crane to lift the roofing sheets directly from the delivery truck onto the roof frame.
Safe handling needed to avoid injury
Use clean dry gloves to handle coated steel sheets for your safety. Don’t slide the sheets over rough surfaces or over each other.
Avoid using lead pencil
It is advisable to avoid using lead pencils to mark on the sheets. The graphite content of a pencil can create an electric cell when it is wet and it causes deterioration of the finish. However you can use a string line with chalk dust or a fine felt-tipped marker.
Mask the holes wherever needed
Holes are often made by drilling or cutting by hole saw or jig saw. Mask the area around the hole to protect the paint from damage by swarf (metal scrap or abrasive particles resulting from cutting and drilling).
Careful while walking on roof
To avoid damage to the roof and oneself, walk carefully on the roof. One should keep weight evenly distributed over the soles of both feet to avoid concentrating the weight on either heel or toes. Always wear soft soled shoes instead of spikes and ribbed soles that pick and hold small stones, swarf or other objects that causes damage to the sheets. When walking parallel to the ribs walk at least on two ribs or corrugation. When you walk across the ribs, walk over or close to the roofing supports.
Fasteners should be of high quality
We recommend you to use top quality screw materials with metal bounded washers. Usage of poor quality screws may lead to early failure of the coated steel.
Proper maintenance of your roofing sheet
Factors that affect the long life of a roof (or wall) are an original design, the environment of the installation and the maintenance of the installation. Maintenance is the biggest factor and it includes
a) Regular inspection for problems before they become a major corrosion sites.
b) Where there is naturally washing by rain water (example roof)
there is usually no additional washing required. However, lack of this requires washing and cleaning, also specially near coastal or industrial influences. Establish a regular routine for washing your roofing sheets. Areas to be washed- include soffits, wall cladding under eaves and the underside of eave gutter. Washing should be done at least once every six months and more frequently in coastal or where high levels of industrial fall out occur to avoid accumulation of salty deposits or industrial dirts.
c) Where regular maintenance does not remove all the dirt wash
the surface with a mild solution of pure soap or non abrasive, soft cloth or soft bristle nylon brush, be gentle to prevent shining spots. Thoroughly rinse off the detergent with clean water. Never use abrasive or solvent cleaner (Like- turpentine, petrol, kerosene and paint thinners) on pre-painted steel surfaces.
d) Removal of leaves and other debris from gutters. e) Keep walls free off soil, concrete and debris near the ground.
Avoid contact with wet concrete
Adhesion between the concrete and AL-Zn coating is not good. Small splashes of concrete on coated steel are damaging and should be removed when wet. The aluminum in the coating will react with the wet concrete leaving the coating porous and prone to corrosion.
Avoid contact with soil
Al-Zn coated steel sheets are to be kept away from contact with soil. The contact between soil or moisture-retaining materials with AL-Zn coated steel sheets will ultimately result in corrosion of the material.
Gutter performs well if it is clean and flawless
The accumulation of debris (Leaf matter, dirt etc.) which results in continual immersion is the most common reason for unsatisfactory performance of guttering. Those particles should be removed and cleaned at regular intervals.
Usage of sealants
Always use good quality sealant to avoid leakage from flashings, capping and gutters.
Avoid corrosion caused by timber
We recommend you to use steel structure frames instead of wooden or timber frame, as the wooden timber may be wet and can produce moisture which will damage your coated sheet. However one may use dry CCA treated timber that must be sealed by painting prior to installation of the coated sheets.
Avoid corrosion caused by chimney
The fallout from boilers and heaters using wood, oil and other fuels can be unsightly and if neglected it can damage the surface on which it falls. Hence it is most important to ensure that the height of the flue is sufficient to create a good draft which will also result in reducing the concentration of the fallout. It is mentionable that corrosion has been found to be related with elevated concentrations of sulphurous products, wood acids and resinous combustion products which have condensed directly from the exiting flue gas. This is associated with the fuel type or inappropriate flue design.
