 High Corrosion Resistance Galvalume Steel Coil for Roofing Sheet and spare parts

Galvalume steel coils  Min/Regular Spangle  Zinc coating: 60-275g/m2  Hot Dipped 55% Aluminum Zinc Alloy Coated Steel by the Hot-Dip Process  Hot Dip Galvalume steel coil EN 10327 JIS G3321, ASTM A792M 55% AL-ZN coated 
The hot dip galvalume steel is a kind of coated steel. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative. 
More than 50 worldwide customers none-risky experiences approved.  DeQiang Steel has been exporting steel coils to more than 50 countries directly. Our long term supply extends to USA, UK, Germany, Italy, Spain, Belgium, France, Poland, Greece, Ukraine, Belarus, Russia, Turkey, Egypt, Saudi Arabia, Iran, Ethiopia, Niger, Brazil, Colombia, Chile, Peru, Australia, New Zealand, etc.

1. Corrugated steel sheet introduction: Corrugated steel sheet is one of the most corrosion resistant corrugated materials offered in the architectural roofing and siding panel market. Unlike normal galvanizing, this metal material is an actual combination of aluminum and zinc to provide excellent protection.Corrugated steel sheet will give you a great product that lasts longer than the traditional galvanized finish. 
2. Corrugated steel sheet main structure: Corrugated steel sheet is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot-dip process described in Production Methods. The nominal coating composition is 55% aluminum and 45% zinc. A small but important amount of silicon is included in the coating alloy.
3. Corrugated steel sheet application scope: Corrugated steel sheet is most commonly used for commercial, agricultural, and industrial purposes, however, it is now also being recognized as an excellent form of residential roofing. Corrugated steel sheet is also known as sinusoidal, corrugated iron or wriggly tin.
4. Corrugated steel sheet main features: 1)Combine the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc. 2)Preferred product for long-term resistance to atmospheric corrosion 3)Superior corrosion resistance. 4)Easy to install, high strength and lower costs 5)Galvanized corrugated sheet is widely used as walls or roofs for factories, warehouses, garages, exhibition centers
5. Corrugated steel sheet installation tips: 1)Prepare the roof surface by removing any old roofing, rotten wood, and adding roofing felt to the entire surface. 2)Calculate the number of sheets of corrugated metal needed. Divide the area of your roof by the size of the sheets you will be using.  3)Place your first metal sheet in a corner of the roof, flush against the surface. 4)Nail in the first metal sheet to the wood of the roof.  5)Place the second metal sheet alongside the first with an overlap of 3 to 4 inches (10 cm).  6)Nail the second metal sheet to the roof.

6. Tools you'll need when install corrugated steel sheet: 1)Sheets of corrugated metal 2)Metal ridge caps 3)Roofing felt (if needed) 4)Nails 5)Hex screws 6)Washers 7)Hammer 8)Drill

Product Description PPGI: 1, Introduction: Color coated steel coils(sheets), i. E. PPGI, also called prepainted steel coils(sheets), are made of galvanized steel coils(sheets) with polymer coatings as surface. It's a new enclosure material and building board with characteristics of light-weighted, heat preserved&insulated, easily installed with bright colors.
2, Production Process: Pretreatment(Degreasing)_Drying_Chromating_Paint Basic Oil_Cooling_Drying_Color Coating_Cooling_Film-covering_Rolling Up
3, Characteristics: Good at corrosion resistence. Besides zinc coating of the basic plate of galvanized steel sheet, the color coating as the surface has double lifetime to ensure better anticorrosion effect.
With excellent cold bending molded manufacturablity, PPGI products can be processed or directly used as final product. As being light-weighted and conveniently transported, they're widly used to replace wood to save energy.
There're thousands of colors can be chosen as per different application. Any color plays well in decoration.
No pollution with high recycling rate, PPGI coils and sheets are strongly recommended as enviroment-friendly products by the government.
4, Appliance: Thanks to the above characteristics, color coated steel coils and sheets are widly used in construction, furniture industry, transportation industry, ect.
5, eye bands and 4 circumferential bands in steel, galvanized metal fluted rings on inner and outer edges, galvanized.
