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.

- Q:What are the potential dangers of handling steel coils?
- There are several potential dangers associated with handling steel coils. Firstly, steel coils are heavy and can pose a risk of physical injury if not handled properly. The weight of the coils can cause strains, sprains, or even more serious injuries if dropped or mishandled. This is particularly true when using manual lifting equipment or when attempting to move the coils without proper training or assistance. Secondly, steel coils often have sharp edges or protruding parts that can cause cuts or puncture wounds if not handled with care. These sharp edges can be especially hazardous when attempting to manipulate or position the coils during transportation or storage. It is important to wear appropriate personal protective equipment, such as gloves, to minimize the risk of injury. In addition, steel coils can become unstable if not adequately secured or balanced. Improper stacking or storage of the coils can lead to them shifting or falling, potentially causing serious injuries or damage. It is crucial to follow proper stacking and storage procedures, including using appropriate equipment and supports, to ensure stability and prevent accidents. Furthermore, steel coils are often stored in areas with limited space or uneven surfaces, increasing the risk of trips, falls, or collisions. It is essential to maintain clear and well-organized storage areas, free of obstacles or hazards, to reduce the likelihood of accidents. Lastly, steel coils can be subject to corrosion or rust, which can weaken the metal and compromise their structural integrity. This can increase the risk of the coils collapsing or breaking during handling, potentially causing injuries or damage to property. Regular inspections and maintenance of the coils, as well as proper storage in dry and well-ventilated areas, can help mitigate this risk. Overall, the potential dangers of handling steel coils include physical injuries from their weight and sharp edges, instability during transportation or storage, accidents due to limited space or uneven surfaces, and the risk of structural failure due to corrosion or rust. It is crucial to follow proper safety protocols, receive appropriate training, and use the necessary equipment to minimize these risks and ensure safe handling of steel coils.
