Wuxi Yansheng Technology Co., Ltd., a trusted manufacturer established in 2017, specializes in high-quality steel products for global construction markets. Our Prepainted Hot Rolled Galvanized Steel Coil GI Color Coated Building Material combines the strength of hot-rolled steel with superior corrosion resistance of galvanized coating and a durable color finish. This product delivers an ideal balance of aesthetics, longevity, and cost-effectiveness for roofing, cladding, and structural applications. With a factory spanning 1,000–2,000 square meters and annual export value exceeding US$50 Million, we ensure consistent quality and timely delivery to overseas clients.
Key Features & Technical Specifications
- Excellent Corrosion Resistance: Hot-dip galvanized zinc layer (60–180 g/m²) protects the base metal, while the color coating adds an extra barrier against moisture and UV.
- Versatile Color Options: Available in RAL standard colors, metallic finishes, or custom shades to meet architectural requirements.
- Superior Adhesion & Flexibility: Prepainted coating (polyester, PVDF, SMP, HDP) is applied via continuous coil coating process, ensuring uniform thickness and excellent formability without cracking.
- Lightweight & High Strength: Hot-rolled substrate provides robust mechanical properties; typical yield strength ranges from 280–550 MPa (depending on grade).
- Easy Installation & Low Maintenance: Color-coated surface resists staining and fading, reducing long-term upkeep costs.
- Eco-Friendly Option: Our products comply with RoHS and REACH regulations (upon request), making them suitable for green building projects.

Frequently Asked Questions
- Q: What is the difference between hot rolled and cold rolled prepainted galvanized coil? A: Hot rolled substrate has thicker gauge and higher strength, suitable for structural applications like roofing. Cold rolled offers better surface finish for decorative uses. Our product uses hot rolled base for superior durability.
- Q: Can you supply custom colors outside the RAL range? A: Yes, we can match specific color codes or provide painted samples for approval. Color consistency is maintained using spectrophotometer checks during production.
- Q: How do you ensure the coating does not peel during forming? A: We use high-quality paint with excellent flexibility (e.g., PVDF or HDP), and conduct T-bend and cross-cut adhesion tests to ensure performance.
- Q: What is the minimum order quantity (MOQ)? A: For standard sizes and colors, MOQ is 1 coil (approximately 3–5 tons). For custom specs, MOQ may be higher; please inquire.
- Q: Do you offer samples before bulk order? A: Yes, we provide free samples (size A4) with only freight collect. Custom painted samples are available at a nominal cost.
- Q: What packing do you use for export? A: Coils are packed with anti-rust paper, plastic film, steel straps, and edge protectors, suitable for sea freight. Additional waterproof packing can be arranged.
- Q: How long does delivery take? A: Standard production takes 15–20 days after deposit. Express delivery for urgent orders may be discussed.
- Q: Does the price include the cost of certification? A: Prices are typically ex-works or FOB; certification costs are included for standard compliance. Additional certifications (e.g., CE, ASTM) can be provided but may incur extra charges.
