The humid and rainy climate has made stainless steel door covers a "perishable item" - the owner of a community in Kunming reported that less than a year after the installation of his door covers, the paint began to peel off at the corners, exposing the iron sheet inside; some door covers in other users' homes were severely rusted due to long-term contact with ground moisture at the bottom. The core of these problems is the failure to choose the right Yunnan stainless steel door cover manufacturer that adapts to Yunnan's climate.

Reliable Yunnan stainless steel door cover manufacturers will make special treatments according to Yunnan's climate: in terms of material, 304 stainless steel is selected for home decoration scenes. Its chromium content is ≥18%, which can form a stable oxide film on the surface to resist moisture corrosion;

If the tooling budget is limited, 430 stainless steel can be selected, but the surface must be chrome plated. The thickness of the plating is more than 0.1mm, which can extend the service life by 3-5 years. In terms of technology, the welding area of the door pocket is fully welded + polished, which is not only beautiful, but also prevents water vapor from penetrating through the weld; a 5cm high waterproof baffle will be installed at the bottom to prevent water vapor from eroding the ground.

When purchasing, be wary of the "low price temptation" - some small manufacturers use 201 stainless steel to pass off as 304 stainless steel. Such products will be attracted by magnets, while authentic 304 stainless steel is almost non-magnetic. It is recommended to choose a Yunnan stainless steel door cover manufacturer that can provide material spectrum testing reports.
