RAL 9012 Prepainted Galvanized Steel Coil 0.2–1.2mm with 700–1250mm Width for Roofing, Construction, and Appliance Panels

RAL 9012 Prepainted Galvanized Steel Coil 0.2–1.2mm with 700–1250mm Width for Roofing, Construction, and Appliance Panels

1. Product Overview

Prepainted galvanized steel coil is used where a finished color surface and basic substrate corrosion protection are required in the same material. In roofing sheets, wall panels, home appliance shells, and light fabricated building parts, the painted surface improves appearance consistency while the galvanized base helps protect the steel underneath.

For this specification, the coil is supplied in a thickness range of 0.2–1.2 mm and a width range of 700–1250 mm. This makes it suitable for cut-to-length production, roll forming, and general panel fabrication in building and appliance applications.

2. Technical Solution

Product performance is based on:

• Hot dipped galvanized substrate as the base protective layer
• Organic paint coating for surface finish and additional barrier protection
• Soft commercial quality or LFQ for common bending and profiling operations
• RAL color system for project-based appearance control
• Standard coil dimensions for mainstream decoiling and roll forming equipment

In practical use, the galvanized base mainly supports corrosion resistance, while the paint system affects surface durability, weathering behavior, and color stability. For visible panels, color consistency and forming performance are usually as important as substrate coating quality.

6. Advantages

• 0.2–1.2 mm thickness range covers common prepainted building sheet applications
• 700–1250 mm width range fits mainstream roofing and cladding lines
• RAL color selection supports architectural and appliance appearance matching
• CGCC and DX51D grades support general forming and panel fabrication
• 508 mm and 610 mm coil IDs are compatible with common industrial equipment
• Suitable for both visible construction panels and appliance-related sheet parts

7. How to Choose

• General roofing and wall panels → polyester is commonly selected
• Projects requiring better weather resistance → SMP can be considered
• Higher UV and long-term exterior exposure → fluoropolymer paint is usually preferred
• Higher rigidity requirement → choose thicker sheet within the 0.2–1.2 mm range
• Visible architectural use → confirm RAL color, gloss, and whether protective film is needed before order

8. FAQ

Q1: Is this product PPGI or PPGL?
This specification is treated as PPGI, which uses a hot dipped galvanized steel substrate with a painted surface.

Q2: What is RAL 9012 used for?
RAL 9012 is a common light-colored architectural and panel finish used where a clean, bright surface appearance is required.

Q3: Can this coil be processed into roofing sheets?
Yes. It is commonly cut, slit, and roll formed into roofing and wall cladding profiles.

Q4: What is the difference between polyester, SMP, and fluoropolymer paint?
They are different paint systems. Polyester is common for standard projects, SMP is used for stronger weather demand, and fluoropolymer paint is generally selected for higher UV resistance and longer exterior service.

Q5: Why are 508 mm and 610 mm coil IDs important?
These are common coil sizes for industrial decoiling and roll forming equipment, so they improve compatibility with standard processing lines.
