Multi-Layer Structure: Hairline Stainless Steel + Steel Plate Spraying
1. Material structure and process design
Surface material:
Hairline Finish: Made of 304 stainless steel (thickness 0.3-1.5mm), formed into a straight texture through cold rolling process, with a delicate touch and anti fingerprint properties, suitable for decorative surfaces in direct contact.
It can be overlaid with etched or PVD coatings (such as titanium gold, rose gold) to enhance the visual effect.
Bottom material:
Spray coated steel plate: Cold rolled carbon steel (thickness 0.5-3.0mm) is selected, and the surface is electrostatically sprayed (powder/fluorocarbon coating). The color can be customized, balancing cost and weather resistance.
2. Composite process steps
Laminated bonding:
Use epoxy resin adhesive or hot melt adhesive film to bond the hairline stainless steel with the sprayed steel plate, and control the pressure (5-10MPa) and temperature (120-150 ℃) to enhance the bonding strength;
The edges are laser welded or bent to avoid the risk of delamination.
Spray coating process:
The surface of the steel plate needs to be phosphated first to improve adhesion, with a spray thickness of 50-150 μ m, supporting matte, metallic paint or imitation wood grain effects.
3. Application scenarios
Architecture and Elevator Decoration:
Elevator door panel: The surface is made of brushed stainless steel to enhance the texture, and the bottom layer is coated with steel plate to reduce the overall cost (compared to a fully stainless steel structure, the cost is reduced by 30% to 50%);
Curtain wall and column wrapping: Composite structure reduces weight (15%~20% lighter than full stainless steel), suitable for high-rise building decoration.
Home and Industrial Design:
Furniture panels: such as cabinet doors and coffee table countertops, with a surface layer that is scratch resistant and a bottom layer that is coated with steel plates for support;
Electrical casing: such as refrigerator side panels and air conditioning casings, with a composite structure that balances appearance and corrosion resistance.
Maintenance suggestion:
Wipe the surface of the stainless steel with a neutral cleaner to avoid scratching with hard objects;
Regularly check the integrity of the coating on the bottom sprayed steel plate, and repair paint for rust prevention in case of local damage.
