Study the Basic Types of Steel Roofing Sheets

Steel roofing sheets are offered by manufacturers and suppliers in various types of materials like corrugated steel, terne coated metal, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum along with other kind of different combination’s. Typically, they come in sizes, shapes and gauges.


A coated steel sheet is available from.50-12 meters in length with thickness of.40mm to.7mm and effective width of 1000 mm. This fabric has existed for almost 200 years. It is very popular for roofing within the construction industry because of its outstanding anti-corrosion and excellent thermal properties. Coated steel sheet is also fire resistant and enjoys high rating if you are a weather tight building material. It is very versatile and flexible and could be formed in to a numerous structural and aesthetic building decors. Coated steel sheet is usually a mix of aluminum-zinc alloy and others.

Corrugated steel roofing sheets have been around in requirement for several years. They come in a number of colors and finishes. The sheets might be procured in lengths from 0.5m approximately 10m and could be utilized for many different types of roofing projects.
Metal roofing sheet (double standing seam) for several years have produced excellent and technically proven roofing products for that construction industry. These thin and materials have excellent anti-corrosion, visual attractiveness and high mechanical properties making them greatly sought after by architects, owners and developers.

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

In relation to galvanized iron sheet, check out a number of its technical specifications. Its base metal is high tensile steel using a coating mass of 120 GSM. The coated STD it is really: 277/JIS 3302 using a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 as per IS: 513 respectively.

Another specialized kind 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 basically that you get less cladding material requirement of covering a curve, less framework support requirement of roofs and reduction of many flashings and capping. End result is critical construction personal savings.

In relation to the galvanized steel sheet, they are greatly sought after in the past century. It is currently a base material for that Polyester and Plastisol roofing coated sheets. Galvanized steel sheet offers its excellent Plastisol sheet quite sturdy. Plastisol is primer coated and the PVC rolled with it extends its lifespan to around 3 decades. It’s also fade and scratch resistant and enjoys a higher fire resistance rating.

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