Roofing Sheets type and their Requirements

Roofing Sheets plays a crucial role in safeguarding buildings, people, and equipment from various weather conditions such as strong winds, rain, water, noise, heat, and cold. To meet the specific needs and requirements of different customers, it is important to provide the right type of roofing solution. The durability of roofing materials relies heavily on galvanized and protective coatings that are directly applied to the steel base. Steel has been a widely used building material for its recyclability. In order to create top-quality pre-coated sheeting, a multi-layer coating system is applied to high tensile steel strip that is already zinc-coated. This coated sheet is then oven-cured to ensure superior adhesion. The end result is a sheet with exceptional resistance to corrosion and weather conditions, along with high strength and abrasion resistance.

Roofing Sheets Types:

There are various types of roofing sheet available pertaining to specific needs and requirements.

PVC Plastisol coated

The pre-finished steel sheet is coated with a high-quality PVC Plastisol, providing a 200-micron layer. This coating boasts an embossed leather grain finish, which not only enhances its appearance but also contributes to its longevity. Typically, this sheet offers a lifespan of 15 to 25 years before requiring maintenance or repainting, and it can last for over 40 years in normal environments. Moreover, it exhibits excellent resistance to scratches and damage, ensuring its durability over time.

Polyester Paint coated

The smooth enamel coating applied to the sheet has a thickness of 25 microns, making it a cost-effective option while providing outstanding weather resistance. Generally, this coating offers a lifespan of 8 to 12 years before requiring maintenance or repainting, and it can exceed 20 years in normal environments. However, it offers only moderate resistance to scratching. Both sheet types come in a wide selection of colors, allowing customers to choose based on their desired aesthetics and performance requirements. Additionally, both types feature a light grey enamel coating on the reverse side.
