Prepainted aluminum coil —— Rolling door
Whether it is the storefront of a shop, a factory warehouse, a residential area, or an underground garage, rolling shutter doors are an indispensable protective and decorative function. There are various types of rolling shutter doors on the market, and aluminum alloy rolling shutter doors have become the preferred choice for many scenarios due to their lightweight, durability, and aesthetic advantages - their core panel is made up of high-quality color coated aluminum coils spliced together.
As an innovative enterprise specializing in the coating, research and development, production, and application of color coated aluminum coils, Litong Aluminum Industry has added strength to aluminum alloy rolling shutter doors with high-quality color coated aluminum coils!
01 Supported by high-quality substrate, all performance is fully utilized
Aluminum coil
Litong Aluminum Industry selects high-quality aluminum alloy substrates from 1 series, 3 series, and 5 series for the application scenarios of rolling shutter doors, ensuring product quality from the source. Compared to traditional materials, aluminum coils have multiple advantages: they are lightweight yet high-strength, weighing much less than steel, yet possessing strength comparable to steel, effectively resisting external impacts; At the same time, it has excellent plasticity, weather resistance, and corrosion resistance, and is not afraid of outdoor wind, sun, rain, and snow erosion. Its service life can reach more than 20 years, greatly reducing maintenance costs in the later stage.
Whether in the hot and sunny southern regions or the cold and harsh northern environments, Litong colored coated aluminum coils can stably perform, keeping the aluminum alloy rolling shutter doors in good condition for a long time and safeguarding the safety of every space.
02 Empowered by roller coating technology, online appearance and quality
Aluminum coil
A good substrate requires a good process. Litong Aluminum Industry adopts a three roll two coating process. The aluminum coil is processed by a leveling machine to ensure the flatness of the board surface and avoid problems such as warping and deformation. Then, the board surface is coated.
In terms of coating treatment, we first use a degreasing and passivation process to remove impurities on the surface of the substrate, greatly improving the adhesion of the coating and making the color more durable and less likely to peel off; Using the synchronous process of three coatings and two baking, layer by layer reinforcement, the surface coating is flawless and color free, and the visual texture is fully stretched. Color coated aluminum coils not only have a beautiful appearance, but also have excellent wear resistance and scratch resistance. They are not easy to scratch or peel off during daily use and maintain a brand new appearance for a long time.
03 High cost-effectiveness, preferred material for rolling shutter doors
Aluminum coil
Compared to traditional materials, aluminum coils are more cost-effective in terms of quality and cost. And Litong Aluminum Industry, from substrate selection to process control, from quality inspection to factory delivery, checks layer by layer to ensure that every roll of color coated aluminum coil meets the standards. Whether it is the production of aluminum alloy rolling shutter doors in various scenarios such as shops, factories, residential areas, etc., choosing Litong color coated aluminum coils means choosing worry free, reassuring, and secure!
Litong Aluminum Industry injects lasting vitality into every rolling shutter door with high-quality color coated aluminum coils, safeguarding space safety and lighting up building aesthetics!
