Product Description

PPGI galvanized steel coil — also called pre painted galvanized steel coil or color coated steel coil — is produced by applying multiple layers of paint onto hot-dip galvanized steel on a continuous coating line. The result is a decorative, corrosion-resistant material that combines the protection of zinc with the beauty and durability of modern paint systems.

At JGT Group, we supply pre painted galvanized steel coil with base thicknesses from 0.15mm to 2.0mm and widths from 600mm to 2000mm. Top coatings include polyester (PE), silicon modified polyester (SMP), high durability polyester (HDP) and PVDF, applied as two-coat or three-coat systems with matching back paint.

Available in hundreds of RAL colors plus custom shades, our coils meet EN 10169, ASTM A755, JIS G3312 and GB/T 12754 standards. Smooth and embossed finishes are offered, and coil coating weights range from Z40 to Z275.

With an annual output of 200,000 tons, JGT Group is a reliable pre painted galvanized steel coil manufacturer and supplier serving customers in more than 100 countries. We support customized colors, dimensions, slitting and packaging, and every shipment includes a mill test certificate.

Main Features

1. Durable Decorative Finish

The pre-painted surface provides a smooth, uniform, attractive finish that retains its color and gloss for decades. PPGI eliminates the need for on-site painting, saving labor and time while delivering a consistent, factory-quality appearance on every panel.

2. Wide Range of Paint Systems

We offer polyester (PE), silicon modified polyester (SMP), high durability polyester (HDP) and PVDF coatings to match every environment and budget. PE suits general indoor and mild outdoor use, while PVDF provides exceptional UV and weather resistance with a service life of 25–30 years in severe climates.

3. Excellent Corrosion Protection

PPGI combines the sacrificial protection of the zinc coating with the barrier protection of the paint film. This dual protection system delivers outstanding resistance to corrosion, fading and chalking even in coastal, industrial and high-humidity environments.

4. Superior Formability & Coating Adhesion

The paint system is applied with precise film thickness and curing control, ensuring strong adhesion that survives stamping, bending, roll-forming and profiling without cracking or peeling. Grades are available for demanding deep drawing operations.

5. Hundreds of Colors & Finishes

Available in more than 300 RAL standard colors plus custom shades, with smooth, embossed and wood-grain finishes. Whether you need standard building colors or a branded custom shade, we can match your requirement with consistent batch-to-batch quality.

6. Consistent Quality & Factory-Direct Supply

Each coil is tested for paint adhesion, film thickness, color consistency, chemical composition and mechanical properties, with a mill test certificate provided for every order. As a factory-direct supplier, JGT Group offers competitive pre painted galvanized steel coil prices with reliable on-time delivery.

Applications

Pre painted galvanized steel coil combines aesthetics with durability for countless applications:

🏗 Building & Construction

Roofing sheets, wall panels, sandwich panels, corrugated sheets, purlins, roller shutters and prefabricated buildings, where color and weather resistance are essential.

🏠 Home Appliances

Refrigerator shells, washing machine housings, microwave ovens, water heaters and air conditioner panels, where a smooth decorative finish is a key buying factor.

🪑 Furniture & Interior

Steel cabinets, lockers, shelving, office partitions and storage systems that require an attractive, durable and easy-to-clean surface.

🚪 Doors & Roller Shutters

Garage doors, roller shutter doors, security doors and window frames, combining strength with color stability in outdoor service.

💨 Ducting & HVAC

Ventilation ducts, cable trays and trunking where a pre-finished surface avoids on-site painting.

📦 Other Applications

Solar mounting frames, fencing, signage, grain silos and general metal goods. Our engineering team can recommend the most suitable coating system and color for your project.

FAQ 

Q1. What is PPGI galvanized steel coil?

PPGI galvanized steel coil, also called pre painted galvanized steel coil or color coated steel coil, is hot-dip galvanized steel strip coated with multiple paint layers on a continuous coating line. It combines the corrosion protection of zinc with a durable, decorative colored surface.

Q2. What is the difference between PE, SMP, HDP and PVDF coatings?

PE (polyester) is the economical standard choice for general use. SMP (silicon modified polyester) offers better weather resistance. HDP (high durability polyester) provides excellent color and gloss retention for coastal and industrial areas. PVDF is the premium system with 25–30 years of service life in severe climates.

Q3. What is the difference between PPGI and PPGL?

PPGI is pre-painted galvanized coil with a zinc coating as the substrate, while PPGL is pre-painted galvalume coil with a zinc-aluminum coating. PPGL offers better heat reflection and corrosion resistance in some environments, and is commonly used for roofing in hot climates.

Q4. What colors are available?

We supply more than 300 RAL standard colors, including red, blue, white, grey and green building shades, plus custom colors matched to your samples. Embossed and wood-grain finishes are also available.

Q5. What is your MOQ and delivery time?

Our MOQ is one 20' container (about 25 tons), and trial orders are accepted for samples. Standard production lead time is 7–15 days after deposit, depending on specification and quantity. We ship from Tianjin Port, China, and can arrange FOB, CIF, CFR and DDP terms.

Q6. Can you provide customized sizes and processing?

Yes. We offer slitting, cut-to-length, edge trimming and custom packaging. You can specify base thickness, width, coating weight, paint system, color, inner diameter and coil weight according to your production needs.

Q7. Do you provide quality certificates?

Every order includes a Mill Test Certificate covering paint film thickness, coating weight, chemical composition and mechanical properties. Third-party inspection such as SGS, BV and TUV is available upon request.
