Precautions for construction of light steel keel suspended ceiling

Light steel keel is made of galvanized steel or thin steel plates rolled by a special rolling mill through multiple processes, with cross-sections in U-shaped, C-shaped, T-shaped, and L-shaped. Mainly used for equipping various types of gypsum boards, calcium plastic boards, sound-absorbing boards, etc., as keel supports for indoor partition walls and ceilings. Compared to wooden keel, it has the characteristics of high strength, fire resistance, moisture resistance, and easy construction. However, steel keel is made of pure steel, which is heavier and has similar properties to light steel keel. The difference in material is that light steel keel is made of thin steel plate, while steel keel is made of pure steel.
Key points for the construction of light steel keel suspended ceiling:
1. Snapping lines: Use a spirit level to mark horizontal points on each corner of the room and pop out a horizontal line.
2. Fixed suspension rods: In general, expansion bolts are used to fix the suspension rods. For non human suspended ceilings, if the length of the suspension rod is less than 1000, it can be used φ If the suspension rod is greater than 1000mm, it should be used φ 8 suspension rods should also be equipped with reverse supports.
3. Installation of side keels: When installing side keels, lines should be marked according to the design requirements. The L-shaped galvanized light steel strip should be fixed to the embedded wooden brick with self tapping screws along the horizontal keel line on the wall. The concrete wall (column) can be fixed with shooting nails, and the distance between them should not be greater than the distance between the secondary keels of the ceiling.
