What's the difference between light steel keel and wooden keel ceiling? What is the current market price difference?

Light steel keel has the following advantages: light steel keel remains unchanged for a long time. Light steel keel, the surface of which is highly galvanized, does not rust for a long time, and is not easily troubled by insects and ants. Light steel keel is a non-combustible material, so there is no fire hazard. The environmental protection of light steel keel completely exceeds that of wood material. Light steel keel installation without noise, firm connection, and ensure environmental hygiene; Light steel keel is a new type of ceiling material, which is widely used in families and projects. Harm of wooden ceiling: Wood materials absorb moisture in the air, especially in the northeast weather, which will inevitably expand with heat and contract with cold, leading to cracking and deformation of gypsum board; Wood materials are easy to breed insects, ants and other organisms, which are harmful to human body. The strength of wood materials is not enough, which is easy to cause problems such as gypsum board sinking and deformation; Code nail connection is easy to loosen and fall off, which may hurt people; Wood materials are flammable and easy to cause fire; Fire retardant coatings will be used in the application of wooden keel, and colloidal materials will be used for bonding during installation, which has strong "formaldehyde" gas volatilization; When installing wooden keel, nail gun must be used, which is noisy and wood chips fly around, irritating the body and skin; Wooden ceiling and partition wall are a kind of structural mode that has been eliminated, and they are no longer allowed to be used in engineering. Considering the construction cost and construction cost, there is little difference between them, and the construction cost of light steel keel is lower.
