Steel roofing sheets can be bought by manufacturers and suppliers in several types of materials like corrugated steel, terne coated stainless-steel, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum and also other sort of different combination’s. Typically, they are available in sizes, shapes and gauges.
A coated steel sheet is available from.50-12 meters in size with thickness of.40mm to.7mm and effective width of 1000 mm. This material has been in existence for up to 200 years. It is very popular for roofing within the construction industry due to its outstanding anti-corrosion and excellent thermal properties. Coated steel sheet can also be fireresistant and enjoys high rating to be a weather tight building material. It is very versatile and flexible and is formed in a countless number of structural and aesthetic building decors. Coated steel sheet can be quite a blend of aluminum-zinc alloy and others.
Corrugated steel roofing sheets come in interest in several years. One can choose from many different colors and finishes. The sheets may be procured in lengths from 0.5m around 10m and is utilized for many kinds of roofing projects.
Stainless-steel corrugated ceiling system (double standing seam) for countless years have produced good quality and technically proven roofing products for the construction industry. These thin and materials have excellent anti-corrosion, visual attractiveness and also mechanical properties making them very much sought after by architects, owners and developers.
A polyester coated aluminum sheet carries a precision rolling coating system using infrared heating technology. It has four roller coating line and thickness which uses an increased molecular polymer as monomer and alkyd. The coating is ultraviolet rays (UV) and inclement safe from nature’s elements. Its gloss finish may be classified as matte and glossy and its paint surface has luster and smoothness inside.
On the subject of Corrugated galvanized iron sheet, examine some of its technical specifications. Its base metal is high tensile steel having a coating mass of 120 GSM. The coated STD it’s: 277/JIS 3302 having a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 according to 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 types of building products. Advantages 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 significant construction financial savings.
In terms of the galvanized steel sheet, they are very much sought after for the past century. It is now a base material for the Polyester and Plastisol roofing coated sheets. Galvanized steel sheet is proud of its good quality Plastisol sheet which is quite sturdy. Plastisol is primer coated and also the PVC rolled into it extends its expected life to about Thirty years. It’s also fade and scratch resistant and enjoys an increased fire resistance rating.
Why don’t you consider 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 due to its versatility, long term performance, beauty and easy installation.
