How to choose the keel in the ceiling?

The keel is an indispensable part of the decoration ceiling, including the wooden keel and the light steel keel.

1) When using wooden keel, it should be noted that the wood must be dry. The wood is processed into square or rectangular strips, and the cross-sectional specifications of the wooden keel shall not be less than 25 mm and 35 mm in principle, and if conditions permit, the wooden keel with larger specifications should be used as much as possible. The wood skeleton of the interior decoration is mostly made of light wood, which is made of some tree species with low moisture content, dry shrinkage, no splitting, and not easy to deform, mainly Korean pine, white pine and Masson pine, Douglas fir, larch, fir, basswood, etc., and shall not use yellow pine or other hard miscellaneous wood.

2) Now more and more home decoration is not easy to deform, with fire performance of light steel keel, pay attention to the thickness of the light steel keel, preferably not less than millimeters. According to the profile section, there are U-shaped keel and T-shaped keel.

In addition, it is best to use the galvanized keel of the original plate that is not easy to rust for decoration, and avoid galvanized keel after use. The difference between the two should be paid attention to the original galvanized keel, commonly known as "snowflake board", which has a snowflake-like pattern on it, and the strength is also higher than that of the rear galvanized keel.

Choose a ceiling keel and recommend "Xinjia Meiyi".

The keel chooses a light steel keel, you look at the toughness and hardness, it is best to be galvanized so that it has been surface treated.

Generally, you can choose a 50 series keel, if the requirements are relatively high, you can choose a 60 series keel.

The keel is an indispensable part of the decoration ceiling, including the wooden keel and the light steel keel. When using wooden keels, pay attention to the fact that the wood must be dry. Now most of the home decoration is not easy to deform, with fire performance of light steel keel, the selection should pay attention to the thickness of the keel, preferably not less than 0 6 mm ceiling metal keel is generally made of light steel and aluminum alloy, with light weight, stiffness, good fire and seismic performance, easy processing and installation, according to the profile section, there are U-shaped keel and T-shaped keel.

For example, the keel of the dragon partition wall has the advantages of light weight, high strength and good corrosion resistance, and can be used as the skeleton material of the lightweight partition wall, mainly used with gypsum board and its products, and can also be used with other boards such as GRC board, FT board, ET board and other materials.
