Mechanism Material and Coating: What to Consider?
The durability of a mechanism is directly related to the quality of the raw material used and the surface coating. The right material determines the product's lifespan.
Steel quality
The load-bearing parts of the mechanism should be made of steel of sufficient thickness and strength. Thin or low-quality sheet metal bends under load and undergoes permanent deformation.
Galvanized coating
Galvanized (zinc) coating protects steel against corrosion. It is a basic requirement, especially for products to be used in humid environments.
Electrostatic powder coating
- Provides both an aesthetic and protective surface.
- More resistant to scratches and impact than galvanizing.
- Blends with furniture design thanks to color options.
Which one, under which conditions?
In dry indoor spaces, galvanizing is often sufficient. For visible parts or demanding use conditions, powder-coated surfaces should be preferred. Stainless steel, on the other hand, is ideal for applications requiring the highest durability.
Material selection is not a cost item but a long-term investment.
Frequently Asked Questions
What is the difference between galvanising and powder coating?
Galvanising adds a zinc layer over the steel to delay corrosion; it is thin and metallic. Powder coating is applied electrostatically and cured in an oven, producing a thicker coloured layer that resists scratching and impact better and looks finished on visible parts.
Does coating increase load capacity?
No. Capacity comes from the thickness and geometry of the load-bearing steel. A coating protects the surface: it extends life but carries no load.
Which option suits humid environments?
Where moisture is constant — bathrooms, kitchens, spaces open to the outside — chrome plating or an electrostatic powder-coated surface is preferred. For heavy, sustained humidity, stainless steel should be considered.
