The main profile wall thickness is 1.8mm, and the frame and fan are designed flush, with a flat and smooth surface.Square pressing line design, stronger three-dimensional sense.The internal opening and broken bridge structure can balance ventilation and protection functions.Standard configuration 304# stainless alloy gauze, it can prevent mosquitoes and particles from entering indoor, with a higher protection coefficient.The double lock points design of the gauze fan, effectively solves the problem of gauze fan shaking.Glue injection expansion corner code process effectively increases splicing strength,

stabilizes structure, and has better load-bearing capacity. Integrated circular arc angle protection, with a flat and seamless appearance, anti-knock and scratch.Standard configuration PA66 Nylon heat insulation strip, effectively achieving heat preservation and insulation performance.EPDM composite foam sealing rubber strip for better soundproof and waterproofing.Three seals at the opening position,effectively ensure air and water tightness; The obvious of drainage structure ensures smooth drainage and good sealing.
