High Weather Resistant Aluminized Zinc Color Coated Steel Coil (PPGL)

 High-weather-resistant aluminized zinc color-coated steel coil is a high-performance building material. It solves the common pain points of traditional steel materials. Many traditional steel products rust easily. They have short service life and high maintenance costs. On-site painting also brings low efficiency and unstable quality. Our product balances protection, aesthetics and economy for your projects.

 Our high-weather-resistant aluminized zinc color-coated steel coil uses a special substrate. The substrate has a gold-proportion alloy coating. It includes 55% Aluminum, 43.5% Zinc and 1.5% Silicon. We combine it with a multi-layer organic coating process. This structure gives the product strong weather resistance. It can withstand long-term exposure to harsh outdoor environments. It does not fade or corrode easily. It works well for projects that need long-term stable performance.

 Premium Weather & Corrosion Resistance

Engineered with 55% aluminum-zinc-silicon substrate and high-performance topcoat, it withstands ≥1000 hours of salt spray testing and 2500 hours of QUV UV aging (≥85% gloss retention). The self-healing aluminum oxide layer effectively resists humidity, acid rain and industrial corrosion, suitable for coastal and harsh outdoor environments.

 Excellent Processing Performance

Outstanding T-bend formability and strong coating adhesion ensure no peeling or cracking during shearing, bending and deep drawing. Uniform coating thickness across the full coil delivers consistent protective and decorative performance.

 Long-Term Cost Effectiveness

With a service life of 15–25+ years (depending on coating grade), it greatly reduces maintenance and replacement costs. High solar reflectivity also reduces building cooling loads, delivering lower total lifecycle cost than standard PPGI.

 Construction & Roofing Systems

Primarily used for corrugated roofing sheets, exterior wall cladding, and sandwich panels. It performs exceptionally well in coastal, industrial, and high-humidity climates, delivering superior UV resistance and anti-corrosion performance that extends building service life with minimal maintenance.

 Industrial & Agricultural Facilities

Applied to factory enclosures, storage tanks, grain silos, poultry barns, and greenhouse structures. Its aluminized zinc substrate withstands chemical fumes, humidity, and temperature swings, making it a reliable choice for demanding operational environments.

 Automotive & Transportation

Suitable for commercial vehicle bodies, refrigerated truck panels, bus siding, and railway interior partitions. The material balances high strength, light weight, and lasting corrosion protection, supporting durable and cost-effective transportation components.

 Home Appliances & General Fabrication

Utilized for appliance housings, roller shutters, garage doors, and outdoor billboards. Its uniform paint finish and excellent formability enable precision fabrication while maintaining consistent color retention and surface quality over time.

 

 We provide professional export packaging for our products. The standard packaging includes waterproof and moisture-proof paper, steel belt fixation and wooden pallet. This packaging protects the products from moisture and damage during transportation. It ensures the products arrive at your place safely.

 We have flexible delivery arrangements. The lead time is 7-15 days for small batch orders after receiving the deposit. For large batch orders, the lead time is 15-30 days. We adjust the time according to your order quantity. We have sufficient production capacity to ensure on-time delivery.

 We ship the goods from two main ports in China. You can choose Qingdao Port or Tianjin Port for delivery. Both ports have perfect logistics networks. They can support global sea freight and land freight to your destination.

 The minimum order quantity is one container, though the minimum for trial orders is negotiable. We welcome small-batch trial orders from new customers. With an annual production capacity of 200,000 tons, we are able to ensure a stable supply for large-scale projects.

Our full product line holds globally recognized certifications including ISO 9001 quality management system and CE safety marking, ensuring strictly standardized production and smooth EU market access. Independently tested by SGS and BV third-party bodies, they fully comply with RoHS and REACH environmental regulations. Complete inspection reports and official certification documents are available to support your project compliance requirements.
