Choosing the right thickness for decorative stainless steel is crucial for decorative projects, as it directly impacts the decorative effect, structural strength, service life, and project cost.
There's no single "correct" thickness, but following the following principles will ensure you make the most appropriate choice.
Core Principles for Selection
Choosing suitable decorative thickness depends primarily on three factors: Application Site, Panel Size and Finish Technology.
1. Application Site
① Interior Applications
Wall cladding, ceilings, cabinet doors, elevator interiors; These sites have lower requirements for structural strength .Common thickness range: 0.6mm-1.2mm.
l 0.6mm-0.8mm:Suitable for flat walls and ceiling, cost-effective, easy to bend and shape.
l 1.0mm-1.2mm: More commonly used, with better flatness and rigidity, less prone to dents or ripples, suitable for areas with high traffic (such as elevator cars and elevator doors).
② Exterior Applications (curtain walls, column cladding, signs) It needs to withstand wind, rain, and temperature fluctuations. Common thickness range is 1.5mm - 2.0mm .
l 1.5mm-2.0mm: Suitable for small and medium-sized curtain wall units and outdoor decoration.
2. Selection by Panel Size
Under the same application, the larger the size of the plate, the required thickness should be increased accordingly to prevent the middle part from sinking and deforming.
l Small Panels (e.g., 1m x 1m):Can use thinner plates.
l Large Panels (e.g., 1.2m x 2.4m or larger):Must use thicker material to maintain a flat, rigid appearance. For a large interior wall, 1.2mm or thicker may be necessary.
3.Consider the Finish Technology
The desired finish can influence the required base material thickness:
l Hairline,Mirror(8K),PVD(Titanium)Coating:These processes require extremely high substrate flatness. If the base material is too thin (e.g., less than 0.8mm), it is prone to deformation during processing, affecting the final result. Therefore, to achieve the best surface effect, it is recommended to choose a thickness of 0.8mm or above.
By following the guidelines above, you can choose the most cost-effective and effective stainless steel decorative panel thickness for your projects.
