Product Introduction: Comprehensive Steel Solutions for Refrigerator Panels
Different components of refrigerators have distinct performance requirements for steel—door panels require high aesthetic appeal and resistance to deformation, side panels prioritize strength and scratch resistance, while back panels must balance heat dissipation and corrosion resistance. Wanzhi Steel provides precisely matched steel grade solutions for each component, ensuring high production yield and long-term reliability for the entire appliance.
With production bases in Shandong and Tianjin, Wanzhi Steel specializes in customized OEM solutions for home appliances. We offer on-demand customization of RAL color codes, orange peel/matte textures, coating thickness, and substrate thickness, and support sheet leveling, slitting, and cut-to-length services.
Recommended Steel Grades for Different Panels of Refrigerators
| Refrigerator Component Locations | Recommended Steel Materials | Common Processes & Surface Finishes | Product Details |
| Refrigerator door panel | Pre-painted color-coated steel (PCM), VCM laminated PVC/PET film steel, 304 stainless steel sheet | RAL color, high gloss/matte; metal sheet + brushed film, pearlescent film, etc. | View VCM |
| Refrigerator left and right side panels | Pre-painted color-coated steel (PCM), textured embossed color-coated steel | Orange peel texture, matte pre-coated finish | View PCM |
| Refrigerator back panel | GI hot-dip galvanized steel, GL aluminized zinc steel | Metal surfaces, simple rust-preventive oil treatment | View GI/GL |
VCM Laminated Steel
The front door panel of a refrigerator is the most visible and frequently touched part of the appliance, so it must be visually appealing and functional (e.g., scratch-resistant, fingerprint-resistant). VCM laminated steel meets these requirements. If your budget is limited, you can also consider PCM steel.
Popular Products
High-Gloss Mirror VCM
A high-gloss PET/PVC film is applied to the surface of the metal sheet, exuding luxury; Used for high-end refrigerator panels and luxury appliance display surfaces.
Textured Effects
A variety of textured films, including brushed, pearlescent, wood grain, leather grain, and ice-patterned finishes, to support differentiated refrigerator designs.
Functional Features
Anti-fingerprint and anti-static functional films. Designed for kitchen environments with grease and dust, VCM steel surfaces are easy to clean and leave no fingerprint marks even after long-term use.

PCM Pre-painted Color-Coated Steel
Refrigerator side panels consist of two panels—left and right—and are areas where a significant amount of steel is used. For cost-effectiveness, PCM color-coated steel is typically chosen, with common colors including white and gray. Among these, orange peel textured color-coated steel can conceal minor defects in the base material and enhance scratch resistance.
Popular Products
RAL9003 Signal White Coated Steel
A pure, high-gloss white that is the mainstream standard color in the home appliance industry. Suitable for refrigerator front doors and side panels; gray is also commonly used.
Orange Peel Texture Coated Stee
Features a uniform, fine embossed pattern that directly enhances the steel sheet’s surface strength and minimizes the visibility of scratches, making it the top choice for refrigerator side panels.
Functional Color-Coated Steel
Available with antimicrobial, oil-resistant, self-cleaning, and anti-static coatings to meet the needs of specialized kitchen, medical, and high-end refrigerator applications.
