The surface of low cost galvalumed steel plate is characteristic of smooth, flat and rich star flowers, and the base color is silver white. The coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon. The production technology of aluminizing zinc is similar to that of the galvanizing steel plate and aluminizing plate. The 55% al - Zn alloy coating has superior corrosion resistance when both sides are exposed in the same environment. The 55% al - Zn alloy coating has not only excellent corrosion resistance but also excellent adhesion and flexibility.
The long-term corrosion resistance of metal coating products mainly depends on the melting rate of coating and coating thickness, the melting rate of galvanized steel plating is higher than that of 55% aluminum-zinc alloy coating. Therefore, the service life of 55% al - Zn alloy coating is longer than galvanized steel plate.
Galvalume steel plate is similar to the silver-white beautiful appearance of the galvanized steel plate and excellent appearance and processing, especially in the steel plate rarely appear processing part crack, the processing part durability is more excellent. In addition, the heat resistance is far better than the galvanized steel plate, thermal reflection than galvanized steel plate more than two times. Uncoated products used in the roof and partition plate can get the effect of energy saving.
Aluminum plating zinc plating layer coating adhesion is relatively good, and therefore without Weathering such as pretreatment, can also directly coated on the advertisement board and usually use plank.

At the end of 2012, Hengze PPGI prepainted galvanized steel coil coating business division successfully developed xizi Otis and Chongqing Otis elevator rolls, and the stable supply of nearly 10,000 tons within a year, becoming the largest elevator rolls supplier of Otis. In September 2013, signed the first batch of elevator volume orders with Tianjin Otis, and mass produced the products on a monthly basis. Shanghai Otis has also carried out close cooperation with Hengze color coating business department since 2013. In recent years, in addition to Otis, constant ze in the elevator industry also has an in-depth cooperation with many well-known brands at home and abroad, including deo elevator, Suzhou, matt yunda Toshiba, Guangzhou, Shenyang, Shanghai Fuji, etc., some of the elevator factory orders are already on a monthly production, some elevator manufacturers also have entered the stage of batch manufacture. Hengze is looking forward to cooperating with more elevator industry leaders in the future to jointly promote the new environment-friendly material -- high quality PPGI prepainted galvanized steel coil in the elevator.
Compared with cold-rolled powder spraying roll (after spraying roll), the advantages of PPGI prepainted galvanized steel coil (pre-spraying roll) lie in the following five points:
1. Environment-friendly processing:
The national requirements for environmental protection are more and more strict, after the powder spraying process is replaced by the color coating process is the trend, change to the color coating coil can eliminate the powder spraying produced by the exhaust gas, wastewater, and even completely abandon the powder spraying line, and Hengze elevator with PPGI prepainted galvanized steel coil has passed the environmental ROHS verification, is a real green environmental protection product.
2. Production capacity is effectively released:
Because the elevator is sent to the processing workshop for the flat, cut size coil, so the post-processing process is omitted, can be directly bent, assembled as a finished door or cage coil, capacity can be greatly increased.
3. Better anti-corrosion durability:
Traditional cold rolling powder spray roll is single-layer spraying, easy to corrosion and cracking; The PPGI prepainted galvanized steel coil is multi-layer coating high-temperature curing, the surface adhesion is stronger, the durability is more superior, the use of many years will not appear shell, crack, peeling powder roll easy to appear defects.
4. More uniform coating thickness:
After the coating roll surface uneven, uneven thickness, PPGI prepainted galvanized steel coil can be strictly controlled according to customer requirements, the back film thickness, and coating density is better.
5. The protective film fits more tightly:
Due to the graininess of the surface, the protective film cannot fit tightly on the roll, which is prone to blister, wrinkle, and other defects. In the process of assembling the elevator, the protective film is easy to break and fall off, so the purpose of protecting the roll cannot be achieved. Hengze elevator with low cost PPGI prepainted galvanized steel coil has a mirror coating effect, added to the PPGI prepainted galvanized steel coil production process to make the protective film closer to the roll, not only will not affect the bending and other processing processes, but also can protect the roll from damage in the process of processing and assembly.
Service and outlook:
With the increasingly strict environmental protection requirements in China, it is becoming more and more obvious to develop and replace the environmentally harmful coating technology elevator roll with the environmentally harmless coating technology elevator roll. In order to keep pace with The Times, the business department of hengze cheap PPGI prepainted galvanized steel coils has developed and improved new functions of elevator rolls, forming a series of specifications and varieties of elevator rolls from practical type to European standard high-grade environmental protection type, which can meet the needs of different customers.
