EN10169 Z120 RAL 8045 ASTM A792 Colour Coated Sheet

1.Product Overview

Pre painted steel sheet is used where a coated metallic substrate and a finished color surface are both required in one material. This configuration is positioned for roofing sheets, wall panels, cladding parts, and general fabricated sheet components that need practical corrosion resistance, stable appearance, and direct downstream processing.

In this specification, the sheet is supplied at 0.5mm thickness, 1000mm width, and 3000mm length with a Z120 coating level and a polyester based paint system. That combination is typically selected for projects that need a balance between formability, surface appearance, and standard exterior panel use.

2.Technical Solution

The product uses a prepainted coating system built on coated steel substrate. The top side uses 15 micron polyester plus 5 micron primer. The back side uses 5-7 micron back coat plus 5 micron primer. In practical fabrication, this coating build supports surface consistency during cutting, bending, and panel forming.

For exterior use, actual service life does not depend on paint layer alone. It is also affected by coating weight, substrate type, panel design, drainage condition, cut edge exposure, and the actual atmosphere at the installation site. For roofing and cladding applications, correct overlap design and fastener detailing remain important to maintain corrosion performance at edges and joints.

3.Specifications

4.Application

• This material is suitable for roofing sheets, wall cladding, façade panels, and general building sheet fabrication.
• It can also be used for light industrial panels, vehicle related exterior panels, furniture components, and electrical equipment housings where a finished painted surface is preferred over post-paint processing.
• For roofing and cladding use, it is more suitable where panel geometry, drainage, and cut edge control are properly designed.

5.Processing

• The sheet can be supplied with or without top side protective film according to handling and installation requirements.
• It is suitable for cutting, bending, roll forming, profiling, and general sheet metal fabrication.
• When the final part has visible surface requirements, film protection and clean handling practice help reduce scratching during transport, storage, and fabrication.

6.Advantages

• The 0.5mm x 1000mm x 3000mm configuration is practical for direct sheet use in roofing and cladding fabrication.
• The Z120 coating level and polyester paint system provide a standard coated structure for general exterior panel applications.
• The top coat and primer system supports appearance consistency and routine forming operations.
• Custom RAL color selection helps match project appearance requirements.
• The broader production range in this series allows size and coating adjustment for different fabrication routes.

7.How to Choose

• Choose 0.5mm when the project needs a practical balance between panel rigidity and forming efficiency.
• Choose Z120 when the application is a general coated sheet project and the environment does not require a heavier metallic coating level.
• Choose polyester for standard use, SMP for better weather exposure, and PVDF when the project has stricter UV and long term finish retention requirements.
• Choose protective film when the painted surface will be exposed to repeated handling before installation.

8.FAQ

Q1. Is this page for a fixed sheet size or a full product range
This configuration is presented as 0.5mm x 1000mm x 3000mm, while the same series also covers wider production ranges in thickness and width.

Q2. What is the coating structure on the top side
The top side uses 15 micron polyester plus 5 micron primer.

Q3. What is the back side coating structure
The back side uses 5-7 micron back coat plus 5 micron primer.

Q4. Can the color be customized
Yes. Color can be supplied according to the RAL card or project requirement.

Q5. Can this sheet be used for roofing and wall panels
Yes. It is suitable for roofing sheets and wall panel fabrication when the panel design and installation details are matched to the service environment.
