The keel in the integrated ceiling includes a variety of different keel materials. However, since different materials are installed in the same ceiling frame, the integrated ceiling has requirements for the type and size of the keel material used. In other words, not all keels can be used in integrated ceilings.
The types of keel materials that can be used in integrated ceilings and their dimensions are as follows:
First, the wooden keel
These keels are made of soft wood materials such as pine or fir. The wooden keel should be straight, without distortion, hard bends and splits. The section size of the main keel is 40mm×60mm, the section size of the secondary keel should be 30mm×40mm, and the section size of the sling should be 50mm×70mm.
Second, light steel keel
The light steel keel of the suspended ceiling should be 50 series. The wall thickness of the galvanized sheet should not be less than 1mm. The main keel and connecting parts should be galvanized, and the coating should be intact and intact. The keel should be straight, without bending or distortion. The lifting ribs of the light steel keel should be made of steel bars, and the fixing parts are made of angle steel. The specifications are generally 30mm×30mm×3mm. Both the hanging ribs and the fixed angle steel should be brushed with anti-rust paint.
The ceiling metal keel is generally made of light steel and aluminum alloy. It has the characteristics of light weight, high rigidity, good fireproof and seismic performance, convenient processing and installation, etc. According to the section of the profile, there are U-shaped keel and T-shaped keel. For example, the partition keel has the advantages of light weight, high strength, good corrosion resistance, etc. It can be used as a skeleton material for lightweight partition walls, mainly used with paper gypsum board and its products, and can also be used with other plates such as: GRC board, FT. Plates, Aite plates and other materials are used together.
Third, aluminum alloy keel
When selecting such keel, it should be noted that the wall thickness should not be less than 0.8mm, and the surface should be treated by anodizing, spray or baking paint. When purchasing, pay attention to the surface of the anti-corrosion layer should be intact, no damage. A qualified aluminum alloy keel should be straight and free of distortion.
The keel is selected to match. When purchasing an aluminum gusset, it is best to purchase it together with the matching keel to prevent inconvenience caused by the type mismatch. For the bathroom that needs to install the ceiling lamp, exhaust fan, Yuba and other electrical appliances, it should be noted that the installation position should be reserved in advance and fixed on the keel, otherwise the aluminum gusset plate will fall off due to excessive force.
Four, triangular keel
The triangular keel is also called the T-shaped keel. It is a commonly used material on the ceiling. Because its shape is a triangular shape, it is called a triangular keel. The triangular keel is one of the paint keels. The triangular keel is a triangular metal skeleton for building which is made of high-quality continuous hot-dip galvanized strip and rolled by cold bending. Usually used together with light steel keels, the light steel keel is U-shaped.
Different materials of the keel play different roles in the integrated dragon skeleton, so the size of the keel also differs depending on its position in the integrated pylon. Source: Dali Daily
