Learn the Basic Types of Steel Roofing Sheets

Steel roofing sheets are sold by manufacturers and suppliers in various kinds of materials like corrugated steel, terne coated stainless-steel, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum and other sort of different combination’s. Typically, they come in different sizes, shapes and gauges.


A coated steel sheet is available from.50-12 meters long with thickness of.40mm to.7mm and efficient width of 1000 mm. This fabric has been in existence for nearly 190 years. It is extremely popular for roofing from the construction industry for the 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 is extremely versatile and flexible and can be formed into a numerous structural and aesthetic building decors. Coated steel sheet can be a blend of aluminum-zinc alloy among others.

Corrugated steel roofing sheets have been around in demand for decades. They are available in numerous colors and finishes. The sheets may be procured in lengths from 0.5m as much as 10m and can be useful for many kinds of roofing projects.
Stainless steel galvanized corrugated panel (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 driving them to a lot 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 which utilizes a higher molecular polymer as monomer and alkyd. The coating is ultraviolet rays (UV) and inclement weather resistant. Its gloss finish may be classified as matte and glossy and its particular paint surface has luster and smoothness in it.

In relation to corrugated galvanized sheet, take a look at a number of its technical specifications. Its base metal is high tensile steel using a coating mass of 120 GSM. The coated STD it’s: 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 sort of steel roofing sheet will be the crimped curved sheets which bring new and innovative look and design. The combined curves and contour shapes and angles produce various building products. Features of this steel roofing sheet is that you simply get less cladding material requirement for covering a curve, less framework support requirement for roofs and avoidance of many flashings and capping. Outcome is critical construction financial savings.

In relation to the galvanized steel sheet, they are a lot in demand for the past century. Now it is a base material for that Polyester and Plastisol roofing coated sheets. Galvanized steel sheet delivers its excellent Plastisol sheet which is quite sturdy. Plastisol is primer coated along with the PVC rolled with it extends its life time about 3 decades. It is usually fade and scratch resistant and enjoys a higher fire resistance rating.

Think about the galvalume sheet steel? This steel materials are a 55% Al-Zn coated steel sheet suited to roofing projects. Many architects, building owners and developers/contractors approve this galvalume steel roofing sheet for the versatility, long-term performance, beauty and ease of installation.
