Process Features

• Hot-Dip Galvanizing Process: The substrate adopts hot-dip galvanizing technology, which ensures uniform zinc layer, strong adhesion and stable anti-corrosion performance, laying a solid foundation for the overall anti-corrosion effect of the product.
• Full-Automatic Roller Coating Technology: Adopt imported automatic roller coating equipment to apply primer, topcoat and back coat in sequence. The coating thickness is precisely controlled, the coating is uniform and smooth, without missed coating or uneven thickness, ensuring product consistency.
• High-Temperature Curing Process: The coated steel coil is cured in a high-temperature oven at 180-220℃. Under precise temperature and time control, the coating forms a dense and hard protective film, which greatly improves the wear resistance, scratch resistance and color fastness of the product.
• Precise Surface Treatment: Before coating, the substrate undergoes degreasing, pickling, water washing, chemical conversion and other multi-step treatments to thoroughly remove oil stains, rust and impurities on the surface, enhancing the adhesion between the substrate and the coating.
• Full-Process Quality Control: Set up multiple quality inspection nodes from raw material incoming inspection, process inspection to finished product inspection, including salt spray test, adhesion test, color difference test, thickness test, etc., to ensure that each batch of products meets the quality requirements.

Application Scenarios

• Prefabricated Building Field: Exterior walls, roofs and interior partitions of prefabricated houses, mobile homes, temporary construction offices and container houses, suitable for rapid construction projects such as urban renewal, construction camps and disaster relief housing.
• Commercial & Residential Building Field: Roofing, wall cladding, canopies and decorative panels of shopping malls, office buildings, hotels, villas and high-rise residential buildings, enhancing the aesthetic value and durability of buildings.
• Infrastructure Construction Field: External protection and decoration of warehouses, workshops, stations, airports, bridges and power facilities, adapting to the harsh environment of infrastructure projects.
• Special Vehicle & Equipment Field: Side panels, cabins and interiors of containers, trucks, RVs and special vehicles, with light weight and good anti-corrosion performance, reducing the weight of vehicles while ensuring service life.
• Interior Decoration Field: Ceilings, wall panels, furniture panels, cabinets and decorative parts, providing a variety of color and pattern options to meet personalized decoration needs.

Core Selling Points

• Dual Anti-Corrosion & All-Climate Adaptation: Hot-dip galvanized substrate + high-adhesion coating forms a dual anti-corrosion barrier, which can adapt to diverse harsh environments such as coastal high-salt fog, Middle East high-temperature drought, European and American rainy and humid areas, and effectively solve the problem of easy corrosion of building materials in special climates.
• Personalized Customization & Aesthetic Upgrade: Support full-process customization of color, pattern, thickness and size; rich color system and surface effects can match different architectural styles and regional aesthetic preferences, realizing the integration of decoration and protection, and improving the grade of the project.
• Cost-Effective & Efficient Construction: Integrate multiple functions such as anti-corrosion, decoration and waterproofing, eliminating the need for secondary painting and multiple construction procedures, shortening the construction period by 40% and reducing labor costs by 30%; light weight design reduces transportation and loading costs, and long service life reduces later maintenance and replacement costs.
• Flexible Order & Global Service: Accept small MOQ (minimum order quantity) trial orders, which is convenient for customers to test the market; provide customized seaworthy packaging to adapt to long-distance sea transportation; support FOB, CIF, DAP and other flexible trade terms, and cooperate with well-known logistics companies to ensure on-time delivery to global ports; professional technical and after-sales teams provide one-stop solutions.
