Steel roofing sheets can be bought by manufacturers and suppliers in a variety of types of materials like corrugated steel, terne coated stainless-steel, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum as well as other sort of different combination’s. Typically, they are available in various sizes, shapes and gauges.


A coated steel sheet is available from.50-12 meters in total with thickness of.40mm to.7mm and efficient width of 1000 mm. This material has been in existence for up to 200 years. It’s very popular for roofing within the construction industry due to its outstanding anti-corrosion and ideal thermal properties. Coated steel sheet can be fire resistant and enjoys high rating for being a weather tight building material. It’s very versatile and flexible and can be formed in a many structural and aesthetic building decors. Coated steel sheet is usually a mixture of aluminum-zinc alloy and others.

Corrugated steel roofing sheets will be in interest in decades. These come in many different colors and finishes. The sheets might be procured in lengths from 0.5m approximately 10m and can be used for many different types of roofing projects.
Metal galvanized corrugated panel (double standing seam) for many years have produced good quality and technically proven roofing products to the construction industry. These thin and materials have excellent anti-corrosion, visual attractiveness and also mechanical properties which makes them greatly in demand 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 safe from nature’s elements. Its gloss finish might be considered matte and glossy and its paint surface has luster and smoothness inside.

In relation to galvanized iron 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 is really: 277/JIS 3302 which has a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 as per IS: 513 respectively.

Another specialized sort of steel roofing sheet could be the crimped curved sheets which bring new and innovative look and style. The combined curves and contour shapes and angles produce various types of building products. Attributes of this steel roofing sheet is that you get less cladding material requirement of covering a curve, less framework support requirement of roofs and avoidance of many flashings and capping. Outcome is crucial construction cost benefits.

When it comes to the galvanized steel sheet, they are greatly in demand for the past century. It’s now a base material to the Polyester and Plastisol roofing coated sheets. Galvanized steel sheet delivers its good quality Plastisol sheet quite sturdy. Plastisol is primer coated and the PVC rolled involved with it extends its lifespan to around 3 decades. Additionally it is fade and scratch resistant and enjoys a top fire resistance rating.

Why don’t you consider the galvalume sheet steel? This steel materials are a 55% Al-Zn coated steel sheet fitted to roofing projects. Many architects, building owners and developers/contractors approve this galvalume steel roofing sheet due to its versatility, long lasting performance, beauty and quick and easy installation.
