Paint keel keel Specification and classification
In the industry of suspended ceiling and partition wall, keel suspended ceiling is widely used, and keel is divided into two series, namely Lightgage Steel Joist And paint keel.
Let me introduce the specifications of these two keels in detail:
Light steel keel is divided into: 38 main keel, 50 main keel, 60 main keel, medium keel, 75 vertical keel, 75 heaven and earth keel, 100 vertical keel, 100 heaven and earth keel, 150 vertical keel, 150 heaven and earth keel, corner bead , U-shaped side dragon, L-shaped side dragon, 50 vertical keels, 50 heaven and earth keels.
The specifications of 38 main keels are divided into 0.6, 0.8, 1.0, 50 main keels are divided into 0.7, 0.8, 1.0 non-standard, 1.0 national standard, 1.2 non-standard, 1.2 national standard, 60 main keels are divided into 0.8, 1.0, 1.2,
The middle keel is divided into 0.35, 0.43, 0.45 and 0.5, and the L-shaped side keel is divided into 0.45, The specifications of U-shaped side keel are 0.35, 0.4, 0.45, 0.6150 vertical keels are 0.8, 1.0, metal corner beads are 0.45, 50 vertical keels are 0.5, 0.6, 50 vertical keels are 0.5, 0.6, 75 vertical specifications are 0.4, 0.5 non-standard, 0.5 national standard, 0.6 non-standard, 0.6 national, 0.7, 0.8, 75 days and ground are 0.4, 0.5 non-standard, 0.5 national standard 0.6, 0.7100 vertical keels are divided into 0.5, 0.6, 0.7, 0.8100 heaven and earth keels are divided into 0.5, 0.6, 0.7150 heaven and earth keels are divided into 0.8; The commonly used specifications are 3m, 3.5m and 4m, which can be customized by the manufacturer according to customer needs.
Painted keel is divided into 32 series, 38 series A type, 38 series B type, 32 groove series, 32 narrow edge plane series, 32 narrow edge groove series. The 32 series is divided into 32 metric systems and 32 imperial systems. The 32 metric system is divided into 32 metric large T, medium T and small T; 32 inch system includes 32 inch system large T, medium T and small T; 32 The corners in the metric system and the imperial system are the same kind of corners, that is, the corners are not divided into the metric system and the imperial system; So the 38 series A corner I will mention later is called 38A corner, and the 38 series B corner is called 38B corner. 38 series A is divided into 38A metric system and 38A British system, including 38A metric large T, medium T and small T; 38A British large T, medium T, small T; Type 38B is divided into type 38B metric large T, medium T and small T; 38B British large T, medium T, small T.
32 groove series is divided into black line English large T, medium T and small T; Black line metric large T, medium T, small T; White line English large T, medium T, small T; White line metric large T, medium T, small T; In addition, the corners of 32 groove series and 32 series are the same kind of corners, that is, 32 corners.
32 Narrow edge plane series is divided into narrow edge plane big T, small T, 32 narrow edge groove series is divided into narrow edge black line big T, medium T, small T; Narrow white line Large T, Medium T, Small T. Among them, the edges and corners of 32 narrow sided plane series and 32 narrow sided groove series are the same kind of edges and corners, that is, narrow edges and corners. Also called L side angle, it is also called unequal side angle.
