FAQ

Why does stainless steel have magnetism?
Austenitic grades are normally non-magnetic, but cold-working can induce martensite → weak magnetism. Use spectral or ID-fluid testing for accurate grade check.
Why does stainless steel rust?
Surface contaminants (iron dust, chloride, acids) break the passive film. Regular fresh-water rinse and avoid contact with carbon steel prevents corrosion.
Can the cover be walked on?
Yes, flange distributes load; rated for 120 kg static point load when fully bedded on silicone.
Do I need sealant on the snap-in part?
Snap gasket gives splash-proof seal; for hose-down or deck-wash areas, add silicone to screws for 100 % watertightness.
Is the plastic UV-resistant for tropical climates?
UV-stabilized ASA/PC blend, 5-year UV-B test shows <3 % color fade.
Can I get a square version or different color?
Square model ZB1302 and custom RAL colors available from 50 pcs MOQ, 3-week lead time.
