Steel roofing sheets are sold by manufacturers and suppliers in several kinds of materials like corrugated steel, terne coated metal, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum along with other form of different combination’s. Typically, these 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. These toppers has been in existence for up to two hundred years. It’s very popular for roofing within the construction industry due to the outstanding anti-corrosion and excellent thermal properties. Coated steel sheet is also fireresistant and enjoys high rating if you are a weather tight building material. It’s very versatile and flexible and is formed in to a many structural and aesthetic building decors. Coated steel sheet can be quite a combination of aluminum-zinc alloy among others.
Corrugated steel roofing sheets have been around in demand for a long time. One can choose from numerous colors and finishes. The sheets may be procured in lengths from 0.5m as much as 10m and is employed 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 lightweight materials have excellent anti-corrosion, visual attractiveness and mechanical properties making them greatly in demand by architects, owners and developers.
A polyester coated aluminum sheet includes a precision rolling coating system using infrared heating technology. It’s got four roller coating line and thickness which uses a high 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 as well as paint surface has luster and smoothness inside.
On the subject of Corrugated galvanized iron sheet, examine several of its technical specifications. Its base metal is high tensile steel which has a coating mass of 120 GSM. The coated STD it’s: 277/JIS 3302 which has a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 according to IS: 513 respectively.
Another specialized form of steel roofing sheet may be the crimped curved sheets which bring new and innovative look and design. The combined curves and contour shapes and angles produce many types of building products. Benefits of this steel roofing sheet is basically that you get less cladding material requirement for covering a curve, less framework support requirement for roofs and removal of many flashings and capping. Outcome is significant construction cost savings.
In relation to the galvanized steel sheet, they have been greatly in demand within the last century. Now it is 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 the PVC rolled into it extends its life span to about 3 decades. It is usually fade and scratch resistant and enjoys a high fire resistance rating.
What 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 due to the versatility, long-term performance, beauty and easy installation.
