Steel roofing sheets are sold by manufacturers and suppliers in a variety of types of materials like corrugated steel, terne coated stainless-steel, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum and other form of different combination’s. Typically, these come in various sizes, shapes and gauges.
A coated steel sheet can be obtained from.50-12 meters in total with thickness of.40mm to.7mm and effective width of 1000 mm. This material has been around for pretty much 190 years. It’s very popular for roofing from the construction industry due to the outstanding anti-corrosion and excellent thermal properties. Coated steel sheet is also fireresistant and enjoys high rating to be a weather tight building material. It’s very versatile and flexible and can be formed in a many structural and aesthetic building decors. Coated steel sheet could be a combination of aluminum-zinc alloy yet others.
Corrugated steel roofing sheets have been around in demand for decades. They come in many different colors and finishes. The sheets might be procured in lengths from 0.5m as much as 10m and can be utilized for many different types of roofing projects.
Metal stainless steel corrugated sheet (double standing seam) for quite some time have produced top quality and technically proven roofing products to the construction industry. These thin and lightweight materials have excellent anti-corrosion, visual attractiveness and mechanical properties causing them to be very much widely used by architects, owners and developers.
A polyester coated aluminum sheet has a precision rolling coating system using infrared heating technology. They have four roller coating line and thickness which uses a high 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 paint surface has luster and smoothness in it.
In terms of Corrugated galvanized iron sheet, take a look at a number of its technical specifications. Its base metal is high tensile steel with a coating mass of 120 GSM. The coated STD it is usually: 277/JIS 3302 with a yield strength of 240 Mpa. Its thickness and tolerance are 0.55mm &.6mm and + 0.03 depending on 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 that you simply get less cladding material dependence on covering a curve, less framework support dependence on roofs and reduction of many flashings and capping. Result is crucial construction financial savings.
In relation to the galvanized steel sheet, to remain very much widely used for the past century. It is currently a base material to the Polyester and Plastisol roofing coated sheets. Galvanized steel sheet offers its top quality Plastisol sheet which is quite sturdy. Plastisol is primer coated and also the PVC rolled into it extends its expected life to about Three decades. It’s also 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 ease of installation.
