• Weatherproof roof Skylight covers: Our attic skylight covers feature 304 stainless steel covers and frames for a rugged 50 kg /110 lb load that can withstand harsh weather such as hail, rain, wind and heavy use
• Rugged: Our roof access doors are made of high-quality galvanized steel with excellent wear and rust resistance. Suitable for a variety of structures, including residential buildings, commercial complexes, industrial plants, warehouses, hotels, restaurants and shopping centers.
• Enhanced security features: In addition to the sturdy structure, the roof access door can only be opened from the inside, effectively preventing unauthorized access to the building from the roof. This additional layer of security is especially valuable for residential and commercial properties where security is critical.
• Well-designed: A 90-degree opening and closing Angle, as well as hydraulic support rods, ensure easy access to the roof area and improve user safety. In addition, the simple on/off handle not only simplifies the opening and closing process, but also provides an intuitive mechanism for easy access to the roof with a simple grip and turn.
• Sealing rubber gasket: Sealing rubber gasket plays a dual role. It significantly reduces the friction noise generated during the opening and closing process, creating a quiet working environment. In addition, it acts as an effective barrier against rain, dust and debris, minimizing the need for internal cleaning.
