What are the classifications of suspended ceilings?

1, light steel keel gypsum board ceiling. Gypsum board is made of gypsum ash as the main raw material, with additives and fibers. It has the properties of light weight, heat insulation, sound absorption, incombustibility and sawability. Gypsum board and light steel keel (pressed by galvanized steel sheet) are combined into light steel keel gypsum board. There are many types of light steel keel gypsum board ceiling, including paper gypsum board, decorative gypsum board, fiber gypsum board and hollow gypsum board strip. There are many specifications on the market. At present, as a partition wall, the light steel keel gypsum board ceiling is rarely used for ceiling modeling.

2, gypsum board smallpox. Mostly used in commercial space, generally using 600x600 specifications, with obvious bones and hidden bones. Keels are usually made of aluminum or iron.

3, splint smallpox. At present, decoration is commonly used. Plywood (also called plywood) is made by cooking and softening logs, cutting them into large pieces along the annual rings, drying, sorting, gluing, assembling blanks, hot pressing and sawing. It has the characteristics of light weight, high strength, good elasticity and toughness, and resistance to impact and vibration. Easy processing and finishing, heat preservation and the like. Smallpox usually uses a 5 cm splint. 3 mm is too thin and easy to arch, 9 mm is too thick. It is popular because it can easily create various shapes of smallpox, including arcs, circles and squares. But there is a disadvantage, fear of termites. The remedy is to spray termite control drugs. Plywood ceiling may fall off after painting for a period of time. The method is to brush varnish (varnish) before decoration, and then do another process after drying. The disadvantage of another splint is that the joints will crack. The method is to fill the joints with putty when decorating.

4, special-shaped strip aluminum gusset plate smallpox. Most of the home improvement materials are no longer used, mainly because they are not resistant to dirt and are easily deformed.

5. Square painted aluminum gusset ceiling. Use in kitchen, bathroom and other places that are easy to get dirty. It is the mainstream product at present.

6, stained glass smallpox. A variety of patterns, internal lighting. For local use only.

7, metal grid smallpox. The corridor or hall used in commercial space feels very modern.
