Steel roofing sheets can be purchased by manufacturers and suppliers in several types of materials like corrugated steel, terne coated metal, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum and other type of different combination’s. Typically, they are available in sizes, shapes and gauges.


A coated steel sheet can be obtained from.50-12 meters in total with thickness of.40mm to.7mm and efficient width of 1000 mm. These components has been in existence for up to two hundred years. It’s very popular for roofing inside the construction industry because of its outstanding anti-corrosion and excellent thermal properties. Coated steel sheet can also be fire resistant and enjoys high rating to be a weather tight building material. It’s very versatile and flexible and could be formed into a multitude of structural and aesthetic building decors. Coated steel sheet can be a blend of aluminum-zinc alloy while others.

Corrugated steel roofing sheets have been in demand for several years. These come in numerous colors and finishes. The sheets might be procured in lengths from 0.5m around 10m and could be useful for several types of roofing projects.
Stainless galvanized corrugated panel (double standing seam) for several years have produced top quality and technically proven roofing products to the construction industry. These thin and materials have excellent anti-corrosion, visual attractiveness and also mechanical properties making them quite definitely widely used by architects, owners and developers.

A polyester coated aluminum sheet features a precision rolling coating system using infrared heating technology. It’s four roller coating line and thickness using a top molecular polymer as monomer and alkyd. The coating is ultraviolet rays (UV) and inclement weather resistant. Its gloss finish might be classified as matte and glossy and it is paint surface has luster and smoothness in it.

In terms of Prepaintedcgi sheet, check out some of its technical specifications. Its base metal is high tensile steel which has a coating mass of 120 GSM. The coated STD it’s: 277/JIS 3302 which has a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 depending on IS: 513 respectively.

Another specialized type of steel roofing sheet may be the crimped curved sheets which bring new and innovative look and style. The combined curves and contour shapes and angles produce various building products. Advantages of this steel roofing sheet is you get less cladding material dependence on covering a curve, less framework support dependence on roofs and avoidance of many flashings and capping. Result is important construction financial savings.

When it comes to the galvanized steel sheet, to remain quite definitely widely used within the last century. Now it is a base material to the Polyester and Plastisol roofing coated sheets. Galvanized steel sheet delivers its top quality Plastisol sheet which is quite sturdy. Plastisol is primer coated and the PVC rolled in it extends its lifespan to about Three decades. It is also fade and scratch resistant and enjoys a top fire resistance rating.

Think about the galvalume sheet steel? This steel material is a 55% Al-Zn coated steel sheet designed for roofing projects. Many architects, building owners and developers/contractors approve this galvalume steel roofing sheet because of its versatility, long term performance, beauty and quick and easy installation.
