Simply put, it consists of two core parts:

Base material: stainless steel plate. Commonly used grades are 304, 304L, 316, 316L, 201, 430, etc., which are selected according to the application environment and cost requirements. Stainless steel provides excellent strength, toughness, corrosion resistance (especially the base layer) and fire resistance.

Surface layer: baking paint coating. Usually composed of primer, color paint (topcoat) and sometimes clear varnish. Under high temperature (usually between 150°C - 250°C), the resin in the paint cross-links and solidifies to form a hard, dense, uniformly colored, high-gloss paint film that is firmly attached to the metal surface.

1. Rich and diverse colors and gloss: This is its most prominent advantage. Almost any color (RAL color card, Pantone color card, etc.) and a variety of effects such as high gloss, matte, metallic paint, pearlescent paint, imitation wood grain, imitation stone grain, etc. can be provided to meet various design needs.

2. Excellent surface flatness and smoothness: After spraying and baking process, the surface is very flat and smooth, easy to clean, not easy to hide dirt, and the visual effect is high-end.

3. Enhanced corrosion resistance: The high-quality paint layer itself has good chemical resistance (acid and alkali resistance, solvent resistance) and weather resistance (UV resistance, humidity and heat resistance), providing an additional protective barrier for the stainless steel substrate, so that it can maintain a good appearance in more demanding environments. Especially for stainless steel with relatively poor corrosion resistance such as 201, the paint layer can significantly improve its overall anti-rust ability.

4. Good scratch and wear resistance: The paint film after high temperature curing has a higher hardness, and is less likely to be scratched or worn than ordinary spraying or PVC film (but not absolutely scratch-proof).

5. Easy to clean and maintain: The smooth and dense surface makes it difficult for oil, dust, etc. to adhere. Just wipe it with a damp cloth or neutral detergent on a daily basis.

6. Environmental protection: Modern baking paint processes mostly use environmentally friendly coatings (such as fluorocarbon coatings PVDF, polyester coatings PE, etc.), with low VOC emissions.

7. Retain some characteristics of stainless steel: such as strength, fire resistance (Class A non-combustible materials), and certain high temperature resistance (depending on the type of paint). 
8. Cost-effectiveness: Compared with complex processes such as pure stainless steel etching and embossing, or using higher-grade stainless steel (such as 316) to achieve better appearance and corrosion resistance, baking paint is a relatively economical and efficient way to achieve rich colors and surface effects.

Application fields of stainless steel paint plate
Due to its beautiful, durable and easy-to-clean characteristics, stainless steel paint plate is widely used in:

Architectural decoration: indoor and outdoor curtain walls, wall decoration panels, elevator cars, door covers, column wraps, ceilings, sunshades, etc.

Kitchen equipment: high-end cabinet door panels, refrigerator panels, range hood panels, disinfection cabinet panels, commercial kitchen equipment shells, etc.

Household appliances: washing machine panels, dryer panels, microwave oven panels, water heater panels, etc.

Furniture: office furniture, bathroom furniture, display cabinets, bar counters, etc.

Transportation:  interior decoration panels of subways, high-speed railways, ships, and buses.

Advertising logos: sign base plates, display racks.

Other industrial uses: clean room walls, laboratory countertops, equipment shells, etc.

Difference from ordinary spraying
"Baking" is the key: ordinary spraying may only be naturally dried or low-temperature baked, the cross-linking curing degree of the paint film is low, and the hardness, adhesion, and durability are far inferior to the paint cured by high-temperature baking.

Performance difference: Paint panels are usually much better than ordinary spray panels in terms of weather resistance, chemical resistance, hardness, wear resistance, adhesion, gloss durability, etc.

Aspects to note
Paint film damage: If the paint film is severely scratched or damaged due to bumps, the internal steel plate is exposed, and rust may still occur in this place under harsh conditions (although stainless steel itself is corrosion-resistant, the damaged edge may still become the starting point of corrosion).

Cost: Compared with ordinary stainless steel plates or spray panels, paint panels are more expensive.

Installation and handling: Careful operation is required to avoid bumps and scratches on the surface.

High temperature limit: Although the substrate is stainless steel, the paint layer has its upper temperature limit (usually not more than 150°C - 200°C, depending on the type of paint). Long-term high temperature will cause the paint film to discolor, powderize or even fall off.

Summary
Painted stainless steel sheet is a functional decorative sheet that perfectly combines the practical properties of stainless steel (strength, corrosion resistance, fire resistance) with the aesthetic decorative properties of paint (rich colors, gloss, flatness). It is widely used in construction, home appliances, home furnishing and industrial fields that have high requirements for beauty, durability and easy cleaning. When choosing, you need to pay attention to the material of the stainless steel substrate, the type of paint coating (such as PVDF fluorocarbon paint has the best weather resistance) and the quality of the processing technology.
