How much is the keel spacing of PVC gusset ceiling

The light steel keel has a ceiling keel and a partition keel according to the use, and there are V-type, C-type, T-type and L-shaped keels according to the cross-sectional form.

1) Product specification series: The main specifications of the partition keel are divided into Q50, Q75 and Q100. The main specifications of the ceiling keel are divided into D38, D45, D50 and D60.

2) Product marking method: the marking order of light steel keel is: product name, code, width of section shape, height, steel plate thickness and standard number.

For example, the cross-sectional shape is "C" type, the width is 50mm, the height is 15mm, and the steel plate thickness is 1 smm, and the ceiling keel is marked as: Light steel keel for construction DC 5 0 XIS XI SGBllg sl

3) Appearance quality: The shape of the light steel keel should be flat, the edges and corners should be clear, 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, tumoring, and falling off. For defects such as corrosion, damage, black spots, pitting, etc., the provisions of Table 2 81 should be complied with when tested according to the prescribed method.

During the appearance quality inspection, visual inspection should be carried out under the condition of bright light at a distance of 0 5m from the product. The surface of the light steel keel should be galvanized and rust-proof, and the amount of double-sided galvanizing is: not less than 120g m*m for excellent products, not less than 100g m*m for first-class products, and not less than 80g m*m for qualified products.

Light steel keel thickness The thickness of light steel keel varies from to to. Under normal circumstances, most people will choose light steel keel when using paper gypsum ceiling, thin gypsum board to use thin keel, gypsum thick to use a thicker keel. There are two kinds of galvanizing of keel, one is hot-dip galvanizing and the other is cold-dip galvanizing.

The price of hot-dip galvanizing is high, and the price of cold-dip galvanizing is low. The ceiling keel is composed of a bearing keel (main keel), a covered keel (auxiliary keel) and various accessories. It is divided into three series: D38 (UC38), D50 (UC50) and D60 (UC60).

D38 is used for hanging point spacing 900-1200mm without people on the ceiling, D50 is used for hanging point spacing 900-1200mm on the ceiling, D60 is used for hanging point spacing 1500mm on the weighted ceiling, U50, U60 for the covering keel, it is used with the bearing keel. The wall keel is composed of transverse keel, vertical keel and transverse brace keel and various accessories, with Q50 (C50), Q75 (C75), Q100 (C100) and Q150 (C150) four series.
