EN 10169 DX51D+Z Color Coated Steel Coil 0.12–1.20mm 700–1250mm for Roofing and Construction Panels

1．Product Overview

EN 10169 DX51D+Z color coated steel coil is used for roofing sheets, wall cladding, building panels, and home appliance parts that require a finished color surface and reliable substrate protection.

The product combines a hot dipped galvanized steel base with a controlled paint coating system. The zinc layer provides corrosion protection for the steel substrate, while the painted surface improves appearance, weatherability, and color consistency for visible applications.

2．Technical Solution

The coil is produced with a galvanized steel substrate and an organic coating system. The zinc coating range is 20–275g/m², allowing selection according to the service environment and required corrosion protection level.

The top surface uses 10–20 micron polyester plus 5 micron primer. The back surface uses 5–7 micron or 7–8 micron polyester plus 5 micron primer. Available paint systems include polyester, SMP, and PVDF for different levels of weather resistance and outdoor durability.

4．Application

This color coated steel coil is suitable for roofing sheets, wall panels, steel structure buildings, warehouses, workshops, airport buildings, storage facilities, and home appliance panels.

It is commonly used where the finished product requires a clean painted appearance, stable forming performance, and corrosion protection for long-term service.

5．Processing

• The coil can be supplied for cut-to-length sheet production.
• It can be slit into narrower widths for roofing sheet and wall panel fabrication.
• It is suitable for roll forming, bending, profiling, and general sheet processing.
• Protective film can be applied on the top side when surface protection is required during processing, transportation, or installation.

6．Advantages

• The galvanized substrate provides corrosion protection with 20–275g/m² zinc coating.
• The 0.12–1.20mm thickness range covers common roofing and panel fabrication requirements.
• The 700–1250mm width range fits mainstream roll-forming and cladding production lines.
• Polyester, SMP, and PVDF paint systems support different weather exposure requirements.
• The defined top and back coating structure helps maintain stable coating quality.
• Coil ID 508mm / 610mm and max. 13 MT coil weight are suitable for standard processing equipment.

7．How to Choose

• Choose polyester for standard roofing sheets, wall panels, and general building applications.
• Choose SMP when improved weather resistance is required.
• Choose PVDF for higher UV exposure and longer outdoor service requirements.
• Choose higher zinc coating levels for humid or more exposed environments.
• Choose thicker material when higher panel rigidity is needed.
• Confirm color, gloss, protective film, coil ID, and final processing method before production.
