Material Selection: Choose based on the degree of environmental corrosion. For general indoor and urban environments, 304 stainless steel is sufficient; for coastal areas, near chemical plants, or roads that may come into contact with de-icing salt, it is recommended to use 316 stainless steel, which has stronger corrosion resistance.
Load-Bearing Rating Determination: Select products with appropriate load-bearing standards based on the actual load (static and dynamic load) of the cover's installation location to ensure safety. Refer to relevant national or industry load-bearing rating specifications.
Size and Opening Design: The cover size must match the reserved trench. The size and spacing of the drainage holes (opening ratio) must meet the expected drainage volume requirements, while preventing high heels, bicycle wheels, etc., from getting stuck.
Surface Treatment: Common surface treatments include natural color (brushed, polished), electroplating, sandblasting, etc. Different treatments affect appearance, anti-slip performance, and fingerprint resistance; selection should be based on aesthetic and functional requirements.
Installation Points: The installation foundation should be flat and firm to ensure the cover is placed stably without shaking. The overlap between the cover plate and the trench should be secure; anchor bolts or clips should be used for fixation if necessary. After installation, check that it is flush with the surrounding ground to avoid tripping hazards caused by height differences.
Post-installation maintenance: Although stainless steel is corrosion-resistant, it is not rust-free. During long-term use, regular inspections should be conducted to remove debris accumulated in the crevices, preventing the long-term accumulation of highly corrosive media such as chloride ions. The surface can be wiped clean with water or a neutral detergent to keep it clean.
