Flat-door waterproof cabinet technology upgrade, sealing structure breakthrough again
May 18, 2026, Industry News —— Addressing pain points of traditional outdoor enclosures such as insufficient waterproof reliability, easy door deformation and rapid seal aging, the flat-door waterproof enclosure has completed its 3rd-generation technical upgrade, focusing on sealing system and structural strength.
Key upgrades:
Flat-door rabbet + double-layer seal: An inner annular rabbet with dual inner/outer foam strips creates a labyrinth seal, improving waterproof performance by 40%;
Reinforced door frame hinges: Thickened galvanized hinges with multi-point locking prevent door sagging and gap widening after long-term outdoor use;
Diversion waterproof design: A top drainage channel guides rainwater away automatically, avoiding water pooling on sealing surfaces;
Weather-resistant sealing material: Modified PU foam strips withstand extreme temperatures (-40℃~+85℃) and aging, extending service life to over 10 years.
Test results show the upgraded product performs excellently in high-pressure water spray, temporary immersion and temperature cycling, with significantly improved protection stability.
