In order to achieve good results, in addition to good decoration materials, perfect decoration skills are also very important. However, when decorating the main keel ceiling, many details must be paid attention to. For example, what is the thickness of the main keel of the ceiling? You know, whether it is too thick or too thin, it will affect the decoration effect. So let's first look at the thickness of the main keel of the ceiling.

Thickness of main keel of suspended ceiling

Light steel joists are divided into suspended ceiling joists and partition joists according to their uses, and V-shaped joists, C-shaped joists, T-shaped joists and L-shaped joists according to their cross sections.

(1) Product specification series: The main specifications of partition keel are divided into Q50, Q75 and Q 100. The main specifications of ceiling keel are divided into D38, D45, D50 and D60.

(2) Product labeling method: The labeling sequence of light steel keel is: product name, code, section shape width and height, steel plate thickness and standard number. For example, the C-shaped ceiling keel has a width of 50mm, a height of 15mm and a steel plate thickness of 1. Smm is marked as: Building Light Steel Keel DC Xixi No.50. SGB law firm.

(3) Appearance quality The light steel keel should be smooth and sharp, and the incision should not have burrs and deformation that affect the use. The galvanized layer is not allowed to have defects such as peeling, swelling and falling off. For corrosion, damage, black spots, pits and other defects. When the test is carried out according to the specified method, the provisions in Table 2-8 1 shall be met. When checking the appearance quality, visual inspection shall be carried out in bright light 0.5m away from the product. The surface of light steel keel shall be galvanized for rust prevention, and the amount of double-sided galvanized shall not be lower than 120g/m*m for high grade, 100g/m*m for first grade, and 80g/m*m for qualified products.

Thickness of main keel of suspended ceiling-thickness of light steel keel

The thickness of light steel keel varies from 0.4mm to 2.0 mm Under normal circumstances, most people will choose light steel keel when using gypsum ceiling, thin keel for thin gypsum board and thick keel for thick gypsum board. There are two kinds of galvanized keels, one is hot dip galvanized and the other is cold galvanized. The price of hot galvanizing is high, and the price of cold galvanizing is low. The ceiling keel consists of bearing keel (main keel), covering keel (auxiliary keel) and various accessories. It is divided into three series: D38(UC38), D50(UC50) and D60(UC60). D38 is used for suspended ceiling, with lifting point spacing of 900- 1200mm, D50 is used for suspended ceiling, with lifting point spacing of 900- 1200mm, D60 is used for counterweight suspended ceiling, with lifting point spacing of 1500mm, and U50 and U60 are decorative keels, which are used together with bearing keels. The wall keel consists of horizontal keel, vertical keel, horizontal lacing keel and various accessories. There are four series: Q50 (C50), Q75 (C75), Q 100 (C 100) and Q 150(C 150).

How to choose the main keel of suspended ceiling

1. How to choose the keel of the ceiling is an indispensable part of the decoration of the ceiling, including wooden keel and light steel keel. When using wooden keel, pay attention to the wood must be dry. At present, most of the family decoration uses light steel keel which is not easy to deform and has fire resistance. Pay attention to the thickness of the keel, not less than 0.6 mm, and choose the original galvanized keel that is not easy to rust in the decoration to avoid the galvanized keel after use.

2, the difference between the two should pay attention to the original galvanized keel commonly known as "snowflake board", with snowflake-like patterns on it, and the strength is higher than that of galvanized keel. The other is gypsum board. When choosing ceiling gypsum board, it is necessary to pay attention to the fact that paper and gypsum should not be separated, and the degree of fit is better. To test the strength of gypsum, you can pinch it with your nails to see if it is hard. If it feels soft, it is an unqualified product. Try to break off the corners of gypsum board by hand, and find that the ones that are easy to break and brittle are unqualified products.

3. General family decoration likes to use the ceiling wrench. How to choose PVC board and metal ceiling? At present, PVC boards and metal ceilings are mostly used in home decoration bathrooms and kitchens. When choosing PVC board, we should not only pay attention to the beautiful and smooth appearance, but also pay attention to the smell of the board. Adding boards with strong pungent smell is harmful to your health, so you should choose tasteless and safe product ceiling. When choosing the ceiling with gold foil, the thickness should not be less than 0.6 mm, otherwise it will collapse easily.

Through the above introduction, I believe that when decorating the main keel of ceiling, we should not only ensure the quality of materials, but also grasp the thickness. Of course, if you don't know anything, we suggest asking professional decoration masters and technicians to operate, so as to achieve better decoration effect.
