There has been a significant shift in the Indian roofing industry from conventional options like tiles to more value-for-money steel roofing solutions. The growth in industrial applications is a major cause for the same. This shift has created a huge demand for different kinds of sheets for protecting the roof in domestic, commercial, and industrial institutions. One of the best options that is available in the market is corrugated roof sheets – distinguished by its unique wavy design and its versatile uses.
What are corrugated roof sheets?
Corrugated roof sheets are fast becoming one of the most popular roofing solutions and can be distinguished by the repetitive folds on their surface. The unique shape of the sheets offers years of reliable utility and greater strength. The corrugated design on the sheets with ridges and grooves make them stronger and durable. Therefore, these wavy construction of corrugated rood sheets makes it ideal for use in smaller surface areas.
It may be noted that galvanised steel sheet usually forms the base for most types of corrugated sheets. It is usually coated by polyester paint or protected by PVC Plastisol. Polyester painted sheets are usually used in agricultural buildings for its medium-length lifespan and economic efficiency. On the other hand, PVC Plastisol coated corrugated sheets comprise steel sheets treated with primer paint and PVC rolled on their surface. These roofing sheets are very durable lasting for around 25-30 years.
In terms of corrugated sheet thickness, these roofing sheets are available in 3 gauges – 0.42, 0.48 and 0.60. While 0.42BMT is used mainly for domestic roofing, the 0.48BMT is more popular for commercial applications. Out of the three 0.60BMT is the heaviest and strongest of all.
In India, regular corrugated sheet price is in the range of ₹250/square meter to ₹500/square meter.
