Welcome to Wuxi Yansheng Technology Co., Ltd. — a trusted manufacturer established in 2017 with a factory spanning 1,000–3,000 square meters and annual export value exceeding US$50 million. Our PPGI Prepainted Galvanized Steel Coil and Galvalume Color Coated Sheet Options represent the pinnacle of quality and versatility for modern construction and industrial applications. Engineered with advanced coating technology, these products deliver exceptional corrosion resistance, vibrant color retention, and outstanding durability, making them an ideal choice for roofing, wall cladding, and structural components.
We offer a comprehensive range of prepainted steel coils and sheets, available in various substrates, including galvanized steel (GI) and galvalume (GL). Our products are produced with strict quality control and come in a wide selection of colors, coating formulations (polyester, HDP, PVDF, SMP), and surface textures. With ISO9001, ISO14000, OHSAS18001 and other certifications, we ensure every coil meets international standards. Below are the key features and specifications you can expect.
Key Features & Specifications
Superior Corrosion Resistance: The galvalume substrate (55% Al, 43.5% Zn, 1.5% Si) provides excellent protection against rust and chemicals, extending service life by up to 3 times compared to standard galvanized steel.
Vibrant Color Coating: Our PPGI/PPGL lines use highly advanced coating systems: Polyester (PE) for basic applications, High Durability Polyester (HDP) for enhanced UV resistance, Polyvinylidene Fluoride (PVDF) for premium weather resistance, and Silicone Modified Polyester (SMP) for industrial environments.
Flexible Size Options: Thickness from 0.12mm to 2.0mm, width from 600mm to 1500mm, all customizable to your exact project requirements. Coil weight ranges from 3 to 10 tons, and slit coils are available upon request.
Excellent Formability: The steel core is manufactured with precise temper rolling, ensuring excellent flexibility for bending, cutting, and profiling without cracking the coating.
Aesthetic Versatility: Choose from over 200 RAL colors, plus metallic, wood, stone, and custom effects. Surface finishes include smooth, embossed (stucco), wrinkle, and matte.
Eco-Friendly Production: Our paint lines use low-VOC coatings, and the entire process complies with ISO14000 environmental management standards.

Frequently Asked Questions (FAQ)
Q1: What is the difference between PPGI and PPGL?
A: PPGI uses galvanized steel substrate (zinc coating), while PPGL uses galvalume substrate (aluminum-zinc alloy). PPGL offers superior corrosion resistance especially in humid or coastal environments, but both are excellent options depending on your budget and environment.
Q2: What colors and coating types are available?
A: We offer all RAL colors and custom colors. Standard coating types: polyester (PE) for indoor or low-exposure applications; HDP for exterior roofing; PVDF for premium weather resistance and color retention; SMP for industrial environments.
Q3: Can you provide cut-to-length sheets instead of coils?
A: Yes, we supply both coils and cut-to-length sheets (custom sizes). Please specify your required length and quantity when ordering.
Q4: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 5 tons. For custom colors or special coatings, MOQ may be 10 tons. Contact our sales team for exact details.
Q5: How long does delivery take?
A: Standard production time is 15–25 days after deposit receipt, depending on order quantity and customization. We ship from multiple ports to optimize logistics.
Q6: Do you provide free samples?
A: Yes, we can send small samples (e.g., A4 size) free of charge; you only pay for shipping. Larger samples may require a nominal fee.
Q7: How is the product packaged for export?
A: Each coil is wrapped with anti-rust paper, plastic film, and metal straps. Sheets are packed in wooden crates or pallets. All packaging meets international shipping standards.
Q8: What certifications do you hold?
A: We are certified with ISO9001, ISO14000, OHSAS18001, SA8000, HACCP, and several other quality and management system standards. Certificates are available upon request.
