1. Construction preparation
how to install metal furring channel ceiling？ The first step is to deepen the design drawings, determine the direction and relative position of various professional pipelines, and determine the elevation of the ceiling bottom; The concealed works inside the ceiling of each profession have passed the acceptance inspection.
2. Snap the horizontal line of the ceiling elevation
According to the 1-meter level control line, measure from the level line to the design height of the ceiling and add the thickness control point of the cover panel. Use a line gauge to lay out the line and mark the position line of the edge keel.
3. Divide the keel dividing line
Determine the position of the suspension rod point on the floor, use a laser plumb to project and mark it.
4. Install ceiling suspension rods
Use expansion bolts to fix the suspension components, with a spacing of no more than 1.2m, and the distance between the suspension rods and the wall edge shall not exceed 30cm; Use an impact hammer to drill holes, and the aperture should be slightly larger than the diameter of the expansion bolt.
5. Install the main keel

The cantilever section of the main keel should not exceed 30cm. When the length of the suspension rod is greater than 1.5m, anti support should be installed.
6. Install secondary keel
The installation of secondary keels should be closely attached to the main keels, with a spacing controlled between 30-60cm. The secondary keels should be connected to the main keels with connecting cards, and secondary keels should be added around the maintenance port. Check the arching condition of the keel using a line gauge (the arching height is 1/200~1/300 of the room span).
7. Wood keel anti-corrosion treatment
Suspended ceiling wooden products shall be coated with fireproof coating at a rate of 500g/m2. The fireproof coating shall be applied in two coats, with a thickness not less than 0.3mm.
8. Install the cover panel

The width of the keel at the joint should not be less than 4cm; A gypsum board should be fixed from the middle to the four sides, and screws should be slightly embedded in the board surface, but should not damage the paper surface. According to the factors at the end of the equipment, during the installation of the gypsum board, mark the hole position and open holes one by one according to the size requirements after the installation of the gypsum board is completed. The distance between gypsum board joints shall not exceed 5mm; Fixed gypsum board nail holes should be treated with rust prevention and leveled with putty.
