Description of Prepainted Galvalume Rolled Coil
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 Prepainted Galvalume Rolled Coil
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.

- Q: why do you need to heat steel when hardening, molecules etc etc
- Metalurgy is a fascinating science which has been used to mark the ages of civilization: the Bronze Age, the Iron Age, etc. Ancient sword makers heated steel until the polished surface showed a straw color (which we now know to be about 550°F, and due to surface oxides) and then plunged the blade into a tank of water. The blade was quickly removed, repolished, and observed closely for heat transfer from the core returning the surface to straw color. If so, it was quenched again. This technique left the surface hard without making the blade brittle. Today the steel crystal lattice is known to be either face centered cubic (iron atoms at the corners of a cube and iron atoms centered in the faces of the cube) or body centered cubic ( iron atoms at the corners of the cube and an iron atom at the geometric center of the cube). Most experienced machinists can estimate the temperature of steel from the color of its surface oxides.
- Q: How are steel coils used in the production of storage racks?
- Steel coils are used in the production of storage racks as they serve as the primary raw material for manufacturing the rack components. These coils are typically cut and formed into various structural shapes, such as uprights, beams, and crossbars, which are then assembled to create the storage rack system. The strength and durability of steel make it an ideal material for supporting heavy loads, ensuring the stability and longevity of the storage racks.
- Q: How do steel coils contribute to the HVAC industry?
- Steel coils are an integral component of the HVAC (Heating, Ventilation, and Air Conditioning) industry and play a crucial role in the functioning and efficiency of HVAC systems. These coils are typically made from high-quality steel, such as stainless steel or galvanized steel, which ensures durability and resistance to corrosion. One of the main ways steel coils contribute to the HVAC industry is by facilitating heat transfer. HVAC systems use coils to transfer heat between the air and a refrigerant. In air conditioning units, for example, the evaporator coil absorbs heat from the indoor air, while the condenser coil releases heat to the outside air. The steel coils in these units provide a large surface area for efficient heat exchange, enabling the cooling or heating of the air as required. Moreover, steel coils also contribute to the overall energy efficiency of HVAC systems. By maximizing heat transfer, these coils allow HVAC systems to operate at optimal performance levels while consuming less energy. This not only helps reduce energy costs for users but also makes HVAC systems more environmentally friendly by minimizing energy consumption and greenhouse gas emissions. Steel coils in HVAC systems also contribute to the quality of indoor air. As air passes over the coils, any impurities, such as dust, dirt, or mold, can accumulate on the coil's surface. Regular maintenance and cleaning of the coils are essential to prevent the buildup of contaminants that could negatively impact air quality. Properly maintained steel coils ensure clean and healthy indoor air, which is particularly important for commercial buildings, hospitals, and other spaces where air quality is crucial. In addition to their heat transfer and energy efficiency capabilities, steel coils also provide durability and longevity to HVAC systems. Steel is a strong and resilient material that can withstand high temperatures, pressure, and environmental stressors. By using steel coils, HVAC systems can operate reliably and efficiently for extended periods, reducing the need for frequent repairs or replacements. Overall, steel coils are a vital component of the HVAC industry. They enable efficient heat transfer, improve energy efficiency, enhance indoor air quality, and provide durability to HVAC systems. Without steel coils, the performance and effectiveness of HVAC systems would be significantly compromised, making them an indispensable element of the HVAC industry.
- Q: How do steel coils contribute to the agricultural sector?
- Steel coils contribute to the agricultural sector by being used in the manufacturing of agricultural machinery and equipment. These coils are used to create components such as plows, harrows, tillers, and seeders, which are essential for cultivating, planting, and harvesting crops. The durability and strength of steel coils make these agricultural machinery and equipment more robust, reliable, and efficient, thereby improving productivity and ensuring higher crop yields.
- Q: I bought a stainless steel water bottle today. I really like it, but there is no drinking spout, it just has a lid that screws on and off, and an open hole to fill it and drink out of. Is this normal for these bottles? Or do they usually come with a spout to drink from? I don't want to look like an idiot at the gym drinking from this cool bottle with no spout if there's supposed to be one! haha.
- That's normal. I'm sure there are caps that you can get that have a built in spout though.
- Q: I am getting a barn soon and I was debating between wood, and steel. I think steel would look nicer [painted of course] and I was wondering which is cheaper. Any extra info would be great. Thanks x

- Q: I plan to buy a bushcraft knife ..The blade made up by damascus steel.My question is ,is damascus steel is very strong ?
- So, there isn't a good answer to your question, because Damascus doesn't describe the actual materials properties of the steel, rather the mechanical construct of the steel. For example: A very common Damascus steel is to layer L6 with 1080 high carbon steel and forge weld the layers together to make a blank, anneal it, then grind it into your blade and heat treat it. (Massive over simplification) That type of Damascus steel is going to be a bit softer than one of the super high carbon exotics, but will be tougher in terms of ability to flex without taking a set, and not chipping out if the edge hits something hard. (assuming it is heat treated well) - edge between RC56 - 58 typically. Another common Damascus steel is layers of VG-10 steel and VG-1 steel also welded together, with the billet then annealed, ground, and heat treated. In this case, because you are using stainless steels you will get a much harder edge - RC 60 - 62 typically. It will have better toughness than plain VG-10, but certainly nowhere near what you can get out of L6 or 52100 or something of that sort. Generally, for a bushcraft knife you typically want something like the first type of Damascus because you are looking for a more all purpose tool, and typically a larger knife. The only problem is that in the bush the first types of steel typically rust. The second type is made up of stain resistant steels and will hold up better. So, this brings me around to - why exactly do you want a Damascus blade on your knife? Are you already looking at one you like? Thinkingblade
- Q: How are steel coils protected from corrosion?
- Steel coils are protected from corrosion through a process called galvanization, where a protective layer of zinc is applied to the surface of the steel. This zinc coating acts as a barrier, preventing moisture and oxygen from coming into direct contact with the steel, thus inhibiting the formation of rust and corrosion.
- Q: I juuuust got a new stainless steel sink only 5 months ago, and it already has a couple rust spots on it.What caused this?!
- if you leave any cast iron pans sit in the sink, rust will show or any silverware also, you can get rid of them with scouring powder but dont scrub too hard or you will scratch the sink
- Q: How are steel coils used in the manufacturing of automotive exhaust systems?
- Steel coils are used in the manufacturing of automotive exhaust systems as they provide the necessary strength and durability required for this critical component. These coils are typically shaped and formed into various parts such as pipes, mufflers, and catalytic converters, which are then welded together to create the exhaust system. The steel coils also undergo additional processes like coating or galvanizing to enhance corrosion resistance, ensuring the longevity of the exhaust system.
