Description of Color Rolled Galvalume Steel Coil for Roof
Aluminum zinc coils is a kind of coated steel coil/sheet. 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. Aluminum zinc coils 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.
Main Feature of Color Rolled Galvalume Steel Coil for Roof
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
Applications of Color Rolled Galvalume Steel Coil for Roof
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

1. What is the minimum order quantity ?
Our MOQ is 50mt for each size. And we will consider to give more discount if you make big order like 1000 tons and more. Further more, the more appropriate payment term your offer the better price we can provide.
2. How long can we receive the product after purchase?
Usually within thirty working days after receiving buyer’s advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-25 days, but the shipment will depend on the vessel situation.
3. How to guarantee the quality of the products？
We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q:I'm a hiker and cook on a camp fire with a canteen cup. So which would be a better material for cooking on a campfire with, aluminum or stainless steel?
- Direct fire will kind of ruin stainless steel. I've screwed up several stainless steel pans cooking directly on a campfire. I have to agree with wildflower the best route by far in a small cast iron pan. They are pretty heavy though.
- Q:ive made lots of knives but they are dark and not shiny. how do i polish a knife and make it shiny
- If the steel knife is dark and not mirror-shiny, then it is probably carbon steel and not stainless steel. If they are carbon steel, then you cannot polish it to a mirror finish - sorry. If there's any rust on them, you can use a very-fine grit sandpaper to remove. Do not put carbon steel knives in the dishwasher, and dry them thoroughly after hand-washing. For long-term storage (meaning you don't plan to use the knife within the next few weeks), wipe the blade a bit with some mineral oil, then store the blade portion of the knife in a plastic bag.
- Q:Is it faster to smith steel or mithril in Rinescape assuming I'm going to mine everything myself?Mining level: 76Smithing level: 55
- steel, it will take you way to long to mine mithril ore, and all the coal. also if you make steel plate bodies they actually sell becuase people use it to make steel titian pouches
- Q:How are steel coils used in the production of steel locks?
- Steel coils are used in the production of steel locks as they provide the raw material required to create the lock components. The coils are processed and shaped into various lock parts such as the housing, shackle, and key mechanism, which are then assembled to form the final lock product.
- Q:How long do steel coils typically last?
- The durability of steel coils is known to last for decades, as it is influenced by various factors including the quality of the steel, maintenance and care, as well as the specific application they are used for. The design of steel coils is generally focused on ensuring longevity by being resistant to corrosion. When properly cared for, regularly maintained, and used within recommended guidelines, steel coils can have a lifespan ranging from 20 to 50 years or more. However, external factors like exposure to harsh environments, extreme weather conditions, and the level of stress they endure can impact their longevity.
- Q:Explain your answers please. I was watching mythbusters and they bought a steel coffin over a wooden one because they thought it would hold more dirt. Now how come bridges that have been made of wood lasted way longer than steel bridges? Or rollercoasts for example.
- steel.
- Q:I have a need to connect various stainless steel tubes and fitting together and was wondering how to do it. I know a TIG welder is an option but have heard rumors that there is a way to solder it in much the same way you affix copper pipe. Perhaps with higher heat and different flux. I need step by step and maybe suppliers of the materials. Thanks in advance and please I do not need the call a plumber answers as I've gotten in the past
- Compression Ferrel connections are the best. for small diameter pipe and tubing. A local hardware shop can supply you with the necessary parts and pieces and can also give you a step by step procedure/self help brochure. This will also allow you to install any valve or t or blank in the piping system. The only tools required will be wrenchs and a tube/piping cutter for this type of installation. Brazing is accomplished by heating the base metal and then the rod. There are different types of brazing rod such as brass, bronze etc.. you will also need a can of flux to coat the rod or you can buy the rod pre-coated. If the seam is flat metal you can use the heat from the brazing tip to make the filler rod follow the direction you want. This also includes vertical such as on an auto body. I would suggest practicing this in a safe area. Always utilize a fire extinguisher, brazing goggles, welding gloves and wear a long sleeve shirt for your protection.
- Q:What are the common methods of joining steel coils?
- The common methods of joining steel coils include welding, mechanical fastening (such as bolts or screws), and adhesive bonding.
- Q:How are steel coils used in the manufacturing of springs?
- Steel coils are used in the manufacturing of springs by being compressed or wound into a helical shape, which provides the necessary flexibility and resistance to support various applications.
- Q:What is the shelf life of a steel coil?
- The duration for which a steel coil remains usable depends on several factors, including the type of steel, storage conditions, and protective measures implemented. Steel coils can generally be stored for a few months to several years. If a steel coil is stored appropriately in a controlled environment with suitable temperature, humidity, and ventilation, its lifespan can be extended. Moreover, if the coil is coated with protective substances like oil or anti-corrosion coatings, its shelf life can be further prolonged. However, if a steel coil is exposed to unfavorable storage conditions such as high humidity, extreme temperatures, or corrosive substances, its shelf life can significantly decrease. Rust and corrosion can occur due to exposure to moisture and oxygen, leading to a decline in quality and structural integrity. To maximize the shelf life of a steel coil, it is crucial to store it in a well-ventilated, dry area, away from direct sunlight and corrosive substances. Regular inspections and maintenance, including cleaning and reapplication of protective coatings, can also help preserve the coil's quality. Ultimately, it is essential to consult the manufacturer or supplier of the steel coil for specific recommendations regarding shelf life, as different types of steel may have varying levels of durability and specific storage requirements.
