Light steel keel is what material to do
Construction process: 3.1 process: ball line, sub-file → do pillow belt (design requirements) → fixed along the top, along the keel → fixed keel keel → installation of vertical keel → installation doors, window frames → installation of additional keel → installation support keel → check keel installation → electrical pipe installation wall equipment → install a mask panel → fill the sound insulation material → install another panel panel → seam and angle treatment → quality inspection

Is the metal with the machine to do it
Materials and main equipment: 2.1.1 Light steel keel: the current wall works using light steel keel mainly support card series keel and through the series keel. Light steel keel main pieces along the top along the keel, strengthen the keel, vertical (horizontal) to the keel, cross the keel. Light steel keel accessories have support cards, Cato, angle care, connectors, fixtures, corners, pressure joints and so on. Light steel keel configuration should meet the design requirements. Keel should have product quality certificate. Keel appearance should be flat surface, angular straight, transition angle and trimming do not allow cracks and burrs, wheat noodles may not have serious pollution, corrosion and mechanical damage. 2.1.2 Fastening material: bolts, expansion bolts, galvanized tapping screws (2mm thick gypsum board with 25mm long screws, two 12mm thick gypsum board with 35mm long screws), wood screws, etc., should meet the design requirements. 2.l.3 Filling materials: glass wool, mineral wool board, rock wool board, according to the design requirements. 2.1.4 Gypsum board: Gypsum board should have product certification. Specifications should meet the requirements of the design drawings. General specifications are as follows: Length: according to the needs of the project to determine; Width: 1200mm, 900mm; Thickness: 9.5mm, 12mm, 15mm, 18mm, 25mm. Commonly used for 12mm. 2.1.5 Seam material: seam putty, fiberglass belt (cloth), 107 glue. 2.1.5.1 WKF joint putty: compressive strength> 3.0MPa, flexural strength> 1.5MPa, final setting time> 0.5h. 2.1.5.2 50mm Mesoporous glass fiber ribbon and fiberglass mesh: cloth weight> 80g / m2, mesh / in Breaking strength: 25mm × 100mm Cloth, warp> 300N Weft> 150N 2.1.6 Main machine: Plate saw, electric scissors, electric self-drilling, electric toothless saw, hand drill, nail gun, DC welding machine, scraper, line fall, by foot and so on.
