Ceiling manhole: high-quality aluminium alloy The surface is painted at 200 ℃, and the color is generally white, which can also be made according to customer requirements other Color and specification can be made into square or rectangle, which can meet the decoration requirements of any ceiling. The inner core of the access opening can be removed from the outer frame for easy installation and maintenance. Access hatch (currently the mainstream access hatch in the domestic market) Gypsum Double aluminum edge inspection trimming [1] (hole) is based on high gypsum Glass Reinforced fiber and aluminum alloy are the base materials, and the products are made by reverse die extrusion. All the raw materials have high degree, high environmental protection, and high cost performance. They are the preferred products in the international decoration industry. In recent years, it has also been widely recognized in the domestic decoration industry! Product features: 1. It is very artistic: the manhole and Ceiling material To form an intact whole, unlike other material manholes (holes), which have obvious connection bulges and affect the appearance, will greatly improve the decoration effect and grade. 2. Height: after the high gypsum powder is used for the production manhole and treated by special process, the product surface is smooth, not deformed, and has excellent weather resistance and durability. 3. Environmental protection and fire resistance: gypsum and glass fiber are Class A materials, which fully meet the needs of building fire safety. 4. Closure: the frame cover at the intersection is made of special profiles, so it has high closure and good decorative effect and appearance. 5. Easy installation: the installation method is the same as that of gypsum board ceiling. Application environment: relevant departments, high hotels, villas and other high places. The aluminum alloy manhole (the earlier and more common open type manhole) is finished with aluminum alloy profile, galvanized iron plate and plastic spraying. The color of the manhole is divided into two types: matt and bright. It was earlier applied to decorative ceiling and is also known. Product features: 1. Good quality: made of aluminum alloy, light weight, strong bearing capacity, no rust, no deformation. 2. Arbitrariness: Any size can be customized, without high abrasive cost and quantity restrictions (such as triangles and polygons). 2. Anti mildew: In the high temperature environment, the dense material of the manhole makes it difficult for mold to grow, which relieves the annoyance of porous sound absorbing materials that are prone to mold breeding. 3. Easy to install: easy to install and fix, it only takes 1-2 minutes to install one. 4. High cleanliness: it can effectively avoid the occurrence of micro dust, and is an ideal choice for places with clean requirements. 5. Easy to use: It is easy to open during maintenance, without special tools. Application environment: Aluminum alloy composite manholes in office buildings, schools, relevant departments, shops and other offices (currently higher than other manholes, produced for customization) are made of special aluminum profiles, oxidation, and special processes. Their aesthetic degree is the same as that of gypsum double aluminum edge inspection manholes. The difference is that the closure is higher, and the gap is only 1mm, Its greater advantages can be customized in any size, all aluminum alloy, better quality! Product features: 1. Arbitrariness: Since this manhole is not affected by the mold, any size can be customized, without high abrasive cost and quantity restrictions. 2. Flexibility: It can be inclined with different cover plates, not affected by thickness, and suitable for groove modeling. 3. Good quality: Made of aluminum alloy, light weight, strong bearing capacity, no rust, no deformation. 4. Closure: the frame cover at the junction is made of special profiles, so it has high closure (smaller than the gypsum double aluminum edge closure gap, which can be ignored), and has a good decorative effect and appearance. 5. Easy installation: the manufacturer has punched holes around the frame profile, which saves installation costs. Application environment: high business buildings, high hotels, villas and other high places. Aluminum alloy composite lower flip manhole (for higher quality, more convenient for lower flip) The aluminum alloy composite lower flip manhole is made of the same material as the aluminum alloy composite manhole. The difference is that the profile is more special and special accessories, which are made by complex processing! Product features: 1. It is more convenient: this type of maintenance can be opened by pushing up slightly to turn down, which is very convenient. 2. Flexibility: It can be inclined with different cover plates, not affected by thickness, and suitable for groove modeling. 3. Arbitrariness: Since this type of manhole is not affected by the mold, any size can be customized, without high abrasive cost and quantity restrictions. 4. Good quality: Made of aluminum alloy, light weight, strong bearing capacity, no rust, no deformation. 5. Easy installation: the manufacturer has punched holes around the frame profile, which saves installation costs. Application environment: high business buildings, high hotels, villas and other high places. Wall access openings (for wall pipe maintenance) are made of aluminum alloy profiles, galvanized sheets, stainless steel locks, and connectors. The color of the access openings is divided into two types: matt and bright. A new generation of wall access openings. Product features: 1. Good quality: made of aluminum alloy, light weight, strong bearing capacity, no rust, no deformation. 2. Anti mildew: In the high temperature environment, the dense material of the manhole makes it difficult for mold to grow, which relieves the annoyance of porous sound absorbing materials that are prone to mold breeding. 3. Easy to install: easy to install and fix, it only takes 2-3 minutes to install one. 4. Easy to use: It is easy to open during maintenance, without special tools. Application environment: wall pipes and various drainage pipes are suitable for broadcasting rooms, hospitals, theaters, classrooms, concert halls, libraries, recreation halls, theater lounges, general offices, shops, hotels, restaurants and gymnasiums.
