Metal Roofing Sheet manufacturer

Steel is the most frequently used metal roofing sheets in both residential and commercial applications, mainly due to its lower cost. Pushpak metal roofing sheets have a better service life with aluminum asphalt coating. Metal roofing sheets manufacturers use variety of metals and alloys including galvanized steel — hot-dip zinc galvanized G-90 and G-60 steel (a less expensive gauge steel, often used in low-end, low-cost corrugated and ribbed metal panels), Galvalume steel — zinc and aluminum-coated steel (a more expensive and longer-lasting coating compared to G-90 galvanized steel), stone-coated steel (G-90 galvanized steel), aluminum, copper, zinc, terne (zinc-tin alloy), and stainless steel. Zinc provides superior corrosion protection in most environments’ accounts for its successful use as a protective coating (Zn 90, Zn 120, ZN 275) for iron and steel products and in many exposure conditions.

Steel sheets: a sustainable Choice

All of the steel roofing products manufactured and distributed by Pushpak are designed to give residential, commercial and industrial end-user durable and more eco-friendly options than traditional materials. Metal sheets are 100% recyclable at the end of their lifecycle as a roof while having 25-95% recycled content, depending on the material used in contrast to other roofing material.
Longevity: Steel roofs last longer than non-metallic roofs, with a general lifespan of 40-70 years.

Fire and Weather Resistant: Steel sheets are incombustible thus can't catch fire. Steel roofing retains up better than any other roofing material under extreme weather conditions of heavy rain, hail, extreme temperatures, high winds, and even earthquakes. They resist wind damage better than other roofing sheet material.

Style Variety: Steel roofing is customizable and available in a wide range of styles. It imitates other materials' physical properties while offers all the durable qualities of steel such as wood shingle, clay tile, and asphalt shingle. And with new technologies in pre-painted galvanized iron(PPGI) and pre-painted galvalume steel(PPGL) surfaces, metal roofing also offers a wide array of colors to choose from.

Cost-Effective with low maintenance: Steel roofing can be quite cost-effective compared to expensive clay tiles, slate, or wood shake shingles for commercial places while providing an aesthetic look. Aluminum asphalt roof coating which forms a shiny, tough, reflective surface helps to keep inside of a building cooler in summer, decrease heating and air conditioning costs. Coupled with its weather-resistant qualities, steel roofs resist the growth of mold and fungus.

Lightweight: Steel roofs reduce the stress on a home’s structure since it is much lighter than materials such as tile. Heavier roof materials may require a roof to undergo structural repairs which can result in thousands of additional costs.

Pushpak Metal Roofing Sheets is available in primarily in Galvanized and Galvalume Steel.
• Galvanized Steel: Is formed cold rolling of a layer of Zinc to protect an inner layer of steel from corrosion. This coating helps extends the life of a steel panel and slows the corrosion process. And because of these corrosion-resistant properties, galvanized steel is the most common steel roofing material.
• Galvalume Steel: Similar to Galvanized, but rather than using a primarily Zinc coating, Galvalume uses a combination of Aluminum and Zinc. The Aluminum better protects against corrosion in certain environments than Galvanized, and also provides a smaller, smoother spangle for a more uniformed appearance.



Dimensions, Shapes and Coatings

• Thickness: Standard thickness is available in 0.50mm (TCT). It is also available in thickness of 0.60mm (TCT)
• Shapes: To be ready for installation, metal roofing materials have to be molded into specific shapes. Here are the most common ones:
Sheets: Sheet metal roofing made of long strips of metal which can be coupled in various ways, depending on the specific needs of the consumer.
Panels: Generally metal roofing panels have square or rectangular shapes with profiles in corrugated or curved shape sheets.
• Profiles: The sheets are available in trapezoidal and sinusoidal profiles.
Trapezoidal and corrugated profiles are generally used as the outer shell in a wall cladding in the construction sector.

Corrugated (Sinusoidal) Metal Roofing Profiles

Corrugated metal roofing consists of metal panels with a wavy pattern, designed to increase the overall resistance of a specific small area. Corrugated panels compare to other metal roofing are heavier because of more metal used in a given area. But, if a lighter material like aluminum is used for making these panels and roofing system lightweight as well. Corrugated roofing has been used in industrial buildings for a long time and with enhanced features, it began to be demanded in residential construction as well. You can find corrugated metal roofing made from stainless steel, aluminum, copper and zinc.

Trapezoidal Metal Roofing Profiles

Trapezoidal profiles are large structural roofing sheets that retain their high load-bearing capability and evolved from the corrugated profile. Trapezoidal profiles are widely used for load-bearing roof shells in dry constructions, room sealing, and slightly sloping roofs. Trapezoidal profiles are used in the roofing sector: As the load-bearing roof shell without thermal insulation, as the load-bearing lower roof shell in a single-shell with a thermally insulated roof on the top and also as the outer skin against the weather in dual-shell constructions. The profiled programme offered by specific manufacturers covers 50+ profile shapes with heights ranging from 10 mm to 200 mm. These profile sheets can cover spaces between the purlins is nearly 10 m. Roofs constructed with trapezoidal profiles have excellent sound suppression characteristics. The sound reduction assessments of up to 53 dB have been achieved. Dual-shell trapezoidal profile cladding walls are used to fulfill the high fire prevention requirements. Another well-known application area is a composite floor. The specially shaped steel trapezoidal profiles set the bonding between the concrete and the steel so that the advantages of the materials being used can be put to good use. Above all else the wide acceptance has resulted from the simple constructive training, the easy, fast assembly, the appealing formal style and last but not least, the cost-efficiency of the trapezoidal profile construction.
• Length: Lengths of metal sheets available as per user's requirements.
• Coatings: Most metal roofing materials should be covered with one or several layers of special paint/finish/coating to be protected from corrosion and other detrimental effects of the environment. These sheets are available in a standard range of colors like Tuscany red, night sky poppy red, Merlin grey, blue, olive green or light grey. However, tin, aluminum, and copper can maintain their durability even when left unfinished.
