Light steel keel ceiling ,,,
Commonly used is 50 to 50 system ,,,
Light steel keel, the surface after the heat crossing zinc treatment, and long no rust, no deformation ,,,
State regulations installed on the light steel keel on the gypsum board, as a class A fireproof material
Wood keel because the water is too large, and love deformation ,,, no fire, so you can see
Large place, no one is covered with wooden keel. The
There are two real problems: 1 "with wood keel, the effect is not bad, and the cost is not cheap ,,, now light steel 50 keel and 3 * 5 wooden cost
Light steel keel has the following advantages: light steel keel long unchanged. Light steel keel, the surface of high galvanized, long no rust, more could not be pest ants. Light steel keel is non-combustible material, no fire hazard Light steel keel environmental protection beyond wood material; light steel keel installation no noise, connected firmly, and to ensure environmental health; light steel keel is a new ceiling material, widely used in home and engineering The Wooden wood ceiling damage: the absorption of air in the air, especially in the northeastern weather, thermal expansion and contraction, inevitable deformation, leading to gypsum board cracking and deformation; wood material easy insects, ants and other organisms, harmful to humans. Wood material strength is not enough, it is easy to produce gypsum board subsidence, deformation and other issues; code nail connection easy to loose, shedding wounding; woody materials flammable, easy to cause fire; wood material keel applications will use fire retardant coating, Material in the installation, there is a strong "formaldehyde" gas volatilization; wood keel in the installation, must use nail gun, the noise is great, and woods flying, stimulate the body skin; wood ceiling, partition is already eliminated A structure, the project has been not allowed to use. From the construction cost and cost of considering the difference between the two little, light steel keel construction costs lower.
Landlord or light steel bar! One word: province.
Light steel keel can be down from the roof down 1-2 meters, for the air conditioning, fire, communication, weak left there are maintenance mouth ,,, people can stand on the light steel keel repair equipment (at this time, the main keel must be 60 main dragon 60 * 27 * 1.2MM),
This is the wood keel will never be able to do
Before ,,, home decoration because the construction is relatively small ,,, hanging under the back and very small, so the carpenter with the wooden side
. But the improvement of living standards ,,,, the use of light steel keel is a big trend ,,,,, in foreign countries are doing so
Domestic, many of the current decoration company, also used the light steel keel ,,, I know that OKorder is the East Yi Sheng, ,, Long hair ,,,,,
3> light steel keel can make a variety of modeling roof, wood keel can not do ,,, is done, the effect is very bad ,,,
4> light steel keel construction fast ,,, good maintenance ,,,,
