3-8 Tons RAL 1013 Ppgi Steel Coils For Building

Product Introduction

PPGI (Pre-Painted Galvanized Iron) steel coils are high-performance metal materials made by coating galvanized steel coils with a protective paint layer through surface pre-treatment, coating application, and baking. The base material is high-quality galvanized steel, and the surface is coated with durable finishes such as Polyester (PE), Silicone Modified Polyester (SMP), High-Durability Polyester (HDP), or Polyvinylidene Fluoride (PVDF) to enhance corrosion resistance, weatherability, and aesthetics. PPGI steel coils are widely used in construction, home appliances, transportation, and agriculture, making them ideal for roofing sheets, wall panels, doors, windows, and appliance enclosures.

Features & Advantages

1. Superior Corrosion Resistance – The galvanized layer provides basic protection, while the color coating enhances durability, ensuring resistance to harsh environments such as humidity and acid rain.
2. Aesthetic Versatility – Available in various colors and textures, including glossy, matte, wood grain, and camouflage, catering to different design needs.
3. Excellent Mechanical Properties – High tensile strength and flexibility allow for easy stamping, bending, and welding, making it suitable for various processing requirements.
4. Long Service Life – High-quality coatings effectively prevent rusting and fading, extending the product lifespan to 15-30 years.
5. Eco-Friendly & Cost-Effective – PPGI steel coils are recyclable, promoting sustainability while reducing maintenance costs.

Applications & Technical Principles

Due to its outstanding performance, PPGI steel coils are widely used in various industries:

• Construction – Roofing, wall panels, ceilings, fences, rolling doors, and decorative structures.
• Home Appliances – Refrigerator panels, washing machine bodies, and air conditioner enclosures.
• Transportation – Shipping containers, truck bodies, and garage doors.
• Agriculture – Greenhouses, farm warehouses, and storage barns.

Technical Principle: The manufacturing process of PPGI steel coils involves continuous coating technology, which includes surface degreasing, chemical treatment, primer and topcoat application, and high-temperature curing. This ensures a uniform and strong adhesion of the coating, improving durability and corrosion resistance, making the product suitable for various demanding environments.
