Steel roofing sheets can be bought by manufacturers and suppliers in numerous varieties of materials like corrugated steel, terne coated stainless steel, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum along with other type of different combination’s. Typically, they are available in various sizes, shapes and gauges.
A coated steel sheet is accessible from.50-12 meters long with thickness of.40mm to.7mm and efficient width of 1000 mm. This material ‘s been around for almost 200 years. It is rather popular for roofing inside the construction industry due to the outstanding anti-corrosion and ideal thermal properties. Coated steel sheet is also fire resistant and enjoys high rating for being a weather tight building material. It is rather versatile and flexible and is formed in a multitude of structural and aesthetic building decors. Coated steel sheet could be a combination of aluminum-zinc alloy among others.
Corrugated steel roofing sheets will be in interest in several years. These come in a variety of colors and finishes. The sheets may be procured in lengths from 0.5m as much as 10m and is useful for many kinds of roofing projects.
Metal corrugated ceiling system (double standing seam) for countless years have produced good quality and technically proven roofing products for that construction industry. These thin and light-weight materials have excellent anti-corrosion, visual attractiveness as well as mechanical properties which makes them very much in demand by architects, owners and developers.
A polyester coated aluminum sheet carries a precision rolling coating system using infrared heating technology. They have four roller coating line and thickness which uses a higher molecular polymer as monomer and alkyd. The coating is ultraviolet rays (UV) and inclement safe from nature’s elements. Its gloss finish may be considered matte and glossy and its particular paint surface has luster and smoothness inside.
In relation to Prepaintedcgi sheet, examine a number of its technical specifications. Its base metal is high tensile steel using a coating mass of 120 GSM. The coated STD is IS: 277/JIS 3302 using a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 much like IS: 513 respectively.
Another specialized type of steel roofing sheet is the crimped curved sheets which bring new and innovative look and style. The combined curves and contour shapes and angles produce various kinds of building products. Advantages of this steel roofing sheet is you get less cladding material requirement for covering a curve, less framework support requirement for roofs and removal of many flashings and capping. Result is critical construction cost benefits.
With regards to the galvanized steel sheet, they’ve been very much in demand within the past century. It is now a base material for that Polyester and Plastisol roofing coated sheets. Galvanized steel sheet offers its good quality Plastisol sheet which is quite sturdy. Plastisol is primer coated along with the PVC rolled involved with it extends its expected life to about 3 decades. Additionally it is fade and scratch resistant and enjoys a higher fire resistance rating.
How about 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 the versatility, long term performance, beauty and quick and easy installation.
