Plywood ceiling Plywood ceiling is usually used for the current decoration of living room and bedroom. Plywood (also called plywood) is made by cooking and softening logs, cutting them into large pieces along the annual rings, drying, sorting, gluing, assembling, hot pressing and sawing. It has the advantages of light material, high strength, good elasticity and toughness, impact and vibration resistance, easy processing, coating and insulation. General ceiling with 5mm plywood, 3mm plywood is too thin and easy to arch. Second, the special-shaped materials of aluminum gusset plate for ceiling are mainly divided into three types: strip, square and grid. Striped painted aluminum gusset ceiling is a kind of strip aluminum gusset, which is generally suitable for walkways and other places, and is helpful to weaken the sense of long and narrow in design. Square aluminum plates are divided into 300mm×300mm and 600mm×600mm specifications. The former is suitable for dirty places such as kitchens and toilets, while the latter is often used in commercial places such as offices. Square aluminum gusset plates can be divided into two types: microporous and non-porous. The main advantage of microporous aluminum gusset plate is that it can breathe air, so that moisture in wet areas such as toilets can enter the top through pores, avoiding the formation of water droplets on the board. When grating aluminum buckle plate, be careful that someone uses stainless steel and iron to fake it. To verify whether it is pure aluminum or impure aluminum or stainless iron, you can use magnets to verify that real aluminum does not attract magnetism, and inferior aluminum or fake aluminum can attract magnetism. But this method is not a complete solution, because unscrupulous merchants can also forge this feature by degaussing. Third, the plastic steel ceiling plastic steel is a reinforced type of PVC, and its strength is greater than that of PVC. Commonly used in kitchens and bathrooms. Advantages: 1, low price; 2. There are many styles and colors; 3, simple installation; 4. Small flat-fell seam gap. Compared with aluminum gusset plate, its disadvantages are: 1, short service life and easy aging; 2, it is easy to change color after a long time; 3, it is not easy to clean, and it is easy to generate static electricity; 4, the texture is slightly worse, after all, the material is different. Fourth, the decoration of stained glass ceiling, in addition to material selection, is mainly the size ratio of modeling. The former should be handled according to the specific situation, while the latter should be calculated on the basis of ergonomics and aesthetics. In terms of height, the indoor clearance height of home decoration should not be less than 2.5m, otherwise try not to make ceiling, and choose gypsum line frame for decoration. If the light steel keel gypsum board ceiling or plywood ceiling is used for decoration, the joints should be sealed with gypsum powder first, then sealed with paper, and then the bottom layer should be painted. Ceiling construction, no matter what kind of material, we must remember one thing: sealing! In case mice and cockroaches nest in it.
