Mostly used in agricultural buildings, corrugated roofing sheets feature repetitive folds on their surface. Because of their unique shape, they offer years of reliable utility and enhanced strength. Their corrugated design with ridges and grooves make them stronger than before. The wavy construction paves the way for increased strength across smaller surface areas.

Because of the special corrugated shape, flimsy and lightweight metals like aluminium can also be equipped to undergo decades of weather beating. As per the pollution levels prevailing where they are installed, corrugated sheets have to be maintained every 5-10 years. Completely durable and eco-friendly, these roofing sheets are ideally used for protecting garages, porches and sheds.

Galvanised steel sheets form the base material for different types of corrugated sheets, such as the ones coated with polyester paint or protected by PVC plastisol coated roof sheets.
Agricultural buildings often use polyester painted sheets because of their medium-length lifespan and economic efficiency.
PVC Plastisol coated corrugated sheets are very durable. They comprise steel sheets treated with primer paint and PVC rolled on their surface. These roofing sheets don’t scratch or fade easily and typically can last for around 25-30 years.

the product Although there are still 2.0mm thick resin tile products on the market, but it is recommended that you do not choose this thin thickness of resin tile, because the thickness of the product is too thin, can not achieve the impact strength, the product is easy to break. Second, the product formulation raw material quality ASA synthetic resin tile surface uses ASA weathering engineering resin material as the product weathering protective layer, and the good weathering grade ASA resin raw material cost price is higher, so if the manufacturer adds too much proportion of calcium powder, reduce the resin The protective layer, then the product cost is reduced a lot, but the product life can not be guaranteed.ans it consists of one layer manufactured in a factory. A PVC roofing membrane is made of thick, flexible UV-resistant thermoplastic material; it may also contain polyester or fiberglass, resins, pigments, plasticizers and other chemicals. The thickness of the roofing membrane varies by manufacturer.

Versatility of PVC Roofing

Although white is a common color since it reflects the sun’s heat, different colors are available. Lighter colors like tan, grey or cream are preferred, and some newerpes of PVC roofing contain reflective elements and are also Energy Star or Cool Roof rated. Some brands of PVC roofing can be customized with colors or logos. Some brands have a design which looks like conventional shingles from a distance.

PVC roofing can be made to fit nearly any flat roof shape, and is considered a fire safe material. This type of prefabricated flat roofing material is also inexpensive and has good general weather resistance. However, it is normally not used in areas with heavy rains or snow. PVC roofing is also may become brittle in very cold weather. Most PVC roofing membranes are designed to last about 15 to 20 years, although some premium products may have longer warranties.

Installation Process

Some PVC membranes come in panels, while others are adhered to the roof deck, and other others held down by stone or concrete. Some brands of PVC roofing are fleeced cushioned, which allows the membrane to be installed on rough substrates. Many types of PVC membranes are hot welded or fused together to make waterproof seams. Specialized welding equipment is used to join the roofing components together.

Installing and maintaining flat roofing is very different than installing standard asphalt shingles. The longevity of PVC roofing often depends on the skill of the installer and the quality of the seams. Homeowners should choose an experienced roofer who has worked with PVC roofing extensively. All PVC roofing should also be inspected every 6 months so any potential problems can be quickly fixed.
