Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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 Rolled steel Coil for Construction Roofing
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 Prepainted Rolled steel Coil for Construction Roofing
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.

- Q:What is steel made of and what is its molecular weight? It's for a project in chemistry class so if you have a website link as well, that would be great!
- Steel is an alloy consisting mostly of iron with a little Carbon thrown in. Steel is not a molecule, therefore, it does not have a molecular weight. Steel contains atoms of iron and carbon in a crystal lattice, along with various other alloying elements such as manganese, chromium, vanadium, and tungsten.
- Q:Which one has more electrical resistivity? Wood or steel? And why?I know that the resistivity depends on the material of the conductor, but i want a perfect explaination please.Thnx in advance :)
- Wood is made up of elements which are non-metals with a high electron affinity. Specifically, carbon, oxygen, hydrogen, and some nitrogen. Furthermore the covalent bond structure in wood means electrons are tightly bound and cannot move easily from atom to another. Not without adding a great deal of energy to the first. Steel is mostly iron, which is a metal. Metals have low electron affinity. The outer electrons in metals are bound very loosely, so that they can move from atom to atom using almost no energy. Metals tend to conduct electricity very easily.
- Q:How do steel coils contribute to earthquake resistance in structures?
- Steel coils contribute to earthquake resistance in structures by providing strength and flexibility. When used in the construction of buildings, steel coils can absorb and dissipate the energy generated by an earthquake, preventing it from causing significant damage. The high tensile strength of steel allows it to withstand the lateral forces and vibrations during an earthquake, ensuring the structural integrity of the building. Additionally, the ductility of steel allows it to bend and deform without breaking, further enhancing its ability to withstand seismic activity.
- Q:What are the different types of steel coatings used on coils?
- There are several types of steel coatings used on coils, including galvanized coatings, zinc-nickel coatings, aluminum-zinc coatings, and organic coatings.
- Q:What are the dimensions of steel coils used in the construction materials industry?
- The dimensions of steel coils utilized in the construction materials industry may differ based on specific requirements and applications. Nevertheless, there exist some commonly employed dimensions. In this industry, steel coils usually possess a width that spans from 600mm to 2,000mm, with the most frequently observed widths being 1,000mm and 1,200mm. The thickness of these coils can fluctuate between 0.4mm and 2.5mm, with the most commonly adopted thicknesses ranging between 0.6mm and 1.2mm. The inner diameter of the coil, commonly referred to as the core size, can vary from 508mm to 610mm, with 610mm being the predominant core size. Moreover, the weight of these coils can also differ, with typical weights ranging from 3 to 15 tons. It is important to emphasize that these dimensions might alter depending on specific project requirements and can be tailored to suit the demands of a particular construction project.
- Q:What are the different types of steel coil surface treatments?
- The different types of steel coil surface treatments include hot-dip galvanizing, electro-galvanizing, organic coating, and pickling and oiling.
- Q:What are the different types of steel coil handling devices?
- There are various types of steel coil handling devices, including coil lifters, coil tongs, coil hooks, coil grabs, and coil carriages.
- Q:I have a steel garage, it looks worn out hauled away? How can I maintain / repair it?
- Maintaining Your Steel Garage: # Clean your garage doors with a mild detergent using a soft car brush four times a year. # Clean the doors whenever they wash you car (washing your garage doors regularly will reduce the build up of corrosive elements) #Avoid using any abrasive cleaners or corrosive chemicals on or around your garage doors. # Avoid using salt near the garage door as it may corrode the door elements / hardware. Or you can paint your steel garage: #Step 1 Clean the door using a low-pressure sprayer. Combine 5 gallons of warm water and 1 cup of low-phosphate detergent to clean the surface. Rinse well and dry the surface. #Step 2 Lightly sand and smooth the scratches which do not go through to the metal substrate. Dust off sand residue. For a door with a baked on finish, use a powdered cleanser (diluted with water) and a soft brush to rough up the surface for better paint adhesion; do not use sand paper. Rinse with water and allow it to dry. #Step 3 Apply primer to areas where scratches permeate to the metal substrate to avoid future rusting or corrosion. Allow it to dry. #Step 4 Paint the door with an even coat of latex exterior house paint. If your steel garage has a dent check out the site(the last source link at the bottom)
- Q:I personally don't believe the story of 8 guys who flew small planes can navigate passenger jets into buildings hundreds of miles away with that precision. It just doesn't make sense.I am wondering what the story surrounding the molten steel was, how could molten steel have been produced when fuel from the planes wasn't hot enough (it melts at 2850 degrees)?
- that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
- Q:How are steel coils used in the manufacturing of marine equipment?
- Steel coils are used in the manufacturing of marine equipment as they provide the necessary strength and durability required for the construction of various components such as ship hulls, bulkheads, decks, and structural supports. These coils are typically used as raw material for cutting, shaping, and welding into the required shapes and sizes, ensuring the marine equipment can withstand the harsh conditions of the sea and maintain its structural integrity.
