Cold Rolled Pre-Lacquered Steel Sheet 1.2mm 1250mm With Or Without Protective

Product Specification

Cold Rolled Pre-Lacquered Steel Sheet 1.2mm 1250mm With Or Without Protective Film

1.Product Overview

Pre lacquered steel sheet is used where a coated steel substrate and a finished color surface are both required in one material. This product covers 0.18mm to 1.2mm thickness and 700mm to 1250mm width, with optional protective film on the top side for surface protection during handling and installation.

The product can be supplied on galvanized steel, galvalume steel, or cold rolled steel base. That allows the sheet to be selected according to corrosion environment, fabrication route, and final appearance requirement.

2.Technical Solution

The sheet uses a multi-layer coating structure. The top side uses 15–20 micron polyester with 5 micron primer. The back side uses 5–7 micron, or 7–8 micron polyester with 5 micron primer. In practical use, this coating build affects surface durability, color stability, and resistance to handling damage.

Available coating systems include PE, SMP, HDP, and PVDF. PE is commonly used for general applications. SMP is selected where better weather resistance is needed. HDP is more suitable where higher coating durability is required. PVDF is generally used where UV resistance and long-term exterior performance are more important.

4.Application

• This material is suitable for construction panels, manufacturing components, automotive related parts, and shipbuilding related sheet applications.
• It can also be used for roofing, wall cladding, and interior decorative parts where a finished painted surface and a controlled sheet size are required.

5.Processing

• The sheet can be supplied in cut length for direct fabrication.
• It is suitable for cutting, bending, roll forming, and general sheet metal processing.
• When the finished surface needs better scratch control during transport or installation, the top side can be supplied with protective film.

6.Advantages

• The 0.18mm–1.2mm thickness range supports light to medium sheet fabrication.
• The 700mm–1250mm width range matches common panel and fabricated sheet routes.
• The 1500mm–5800mm length range supports both shorter fabricated parts and larger panel layouts.
• Multiple base metal options allow selection by corrosion environment and end use.
• Multiple coating systems allow the sheet to be matched to standard indoor use or more demanding exterior exposure.

7.How to Choose

• Choose galvanized steel base for general painted sheet applications where zinc coated substrate is required.
• Choose galvalume steel base when improved corrosion resistance and heat reflectivity are more important.
• Choose cold rolled steel base when the application is mainly for interior or protected-use fabrication.
• Choose PE for standard applications, SMP for stronger weather exposure, HDP for higher durability demand, and PVDF for long-term exterior service.
• Choose thickness according to panel rigidity, forming route, and installation span.
