Steel roofing sheets are sold by manufacturers and suppliers in a variety of varieties of materials like corrugated steel, terne coated stainless, aluminum coated, copper, aluminum-zinc, galvalume or galvanized steel and aluminum and also other kind 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 length with thickness of.40mm to.7mm and effective width of 1000 mm. These components has been in existence for up to 190 years. It is very popular for roofing within the construction industry for the outstanding anti-corrosion and ideal thermal properties. Coated steel sheet can also be fireresistant and enjoys high rating for being a weather tight building material. It is very versatile and flexible and is formed right into a countless number of structural and aesthetic building decors. Coated steel sheet is usually a blend of aluminum-zinc alloy and others.
Corrugated steel roofing sheets come in requirement for decades. They are available in a variety of colors and finishes. The sheets could be procured in lengths from 0.5m around 10m and is employed 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 to the construction industry. These thin and light-weight materials have excellent anti-corrosion, visual attractiveness and high mechanical properties making them a lot sought after by architects, owners and developers.
A polyester coated aluminum sheet carries 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 could be classified as matte and glossy and its paint surface has luster and smoothness inside it.
In terms of corrugated galvanized sheet, have a look at a few of its technical specifications. Its base metal is high tensile steel using a coating mass of 120 GSM. The coated STD it is really: 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 kind 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 get less cladding material dependence on covering a curve, less framework support dependence on roofs and removal of many flashings and capping. Final result is crucial construction financial savings.
In terms of the galvanized steel sheet, they have been a lot sought after within the past century. It’s now a base material to the Polyester and Plastisol roofing coated sheets. Galvanized steel sheet is proud of its excellent Plastisol sheet quite sturdy. Plastisol is primer coated and also the PVC rolled into it extends its life time to around Thirty years. It is usually fade and scratch resistant and enjoys a higher fire resistance rating.
What about the galvalume sheet steel? This steel material is a 55% Al-Zn coated steel sheet fitted to roofing projects. Many architects, building owners and developers/contractors approve this galvalume steel roofing sheet for the versatility, lasting performance, beauty and easy installation.
