Application and technological innovation of PPGI/PPGL coils in modern architecture

With the rapid development of the global construction industry, the selection and performance optimization of building materials have become the core of the industry's attention. Among them, pre-coated galvanized steel coils (PPGI) and pre-coated galvanized steel coils (PPGL) have gradually become important materials in the construction field due to their excellent corrosion resistance, aesthetics and economy.

Technical features: all-round optimization from substrate to coating

The core advantage of PPGI/PPGL coils lies in their multi-layer structural design and high-performance coating technology. Its substrate is usually cold-rolled steel or hot-dip galvanized steel as the basis. After precise surface treatment, it is covered with one or more layers of organic coating through a continuous coating process. These coatings not only give the material excellent UV resistance, weather resistance and corrosion resistance, but also provide a rich color selection to meet the diverse needs of architectural design.
Substrate selection: PPGI coils are based on hot-dip galvanized steel sheets, while PPGL uses galvanized steel sheets. Both have good mechanical strength and corrosion resistance, but PPGL has better durability in extreme environments because of the aluminum element in the coating.
Coating process: Coating is the core competitiveness of PPGI/PPGL coils. Modern coating technology includes multiple combinations of primer, topcoat and backcoat, among which the topcoat often uses materials such as polyester (PE), silicon-modified polyester (SMP) or fluorocarbon (PVDF). The application of different coating materials makes it suitable for different climatic conditions and usage scenarios, such as high temperature, high humidity or strong ultraviolet areas.
Environmental performance: With the popularization of the concept of green building, construction ppgi / ppgl coil have gradually introduced low VOC (volatile organic compound) coatings and recyclable processes in the production process, further enhancing their environmental value.

Application scenarios: from industrial plants to high-end residences

PPGI/PPGL coils have been widely used in multiple construction fields due to their excellent performance and flexibility. The following are several typical application scenarios:
Industrial buildings: In the construction of industrial plants and warehouses, PPGI/PPGL coils are widely used for roof panels and wall panels. Its light weight and high strength characteristics not only reduce the load on the building structure, but also significantly shorten the construction period. In addition, its excellent corrosion resistance enables it to cope with chemical erosion common in industrial environments.
Commercial buildings: In commercial buildings such as shopping malls and office buildings, PPGI/PPGL membranes add visual appeal to buildings with their rich colors and smooth surface texture. At the same time, their weather resistance and self-cleaning functions reduce later maintenance costs.
Residential buildings: In recent years, PPGI/PPGL membranes have gradually entered the high-end residential market, especially in roof and exterior wall decoration. Its good thermal insulation and waterproof properties make the living environment more comfortable and energy-saving.
Infrastructure: PPGI/PPGL membranes are also widely used in infrastructure projects such as bridges, tunnels and highway noise barriers. Its durability and weathering resistance ensure the long-term and stable operation of these facilities in harsh environments.
