When installing light chandeliers, it is necessary to preset 400 × 400mm 18mm thick multi-layer boards at the mounting position. The board surface is flush with the wood keel side. The multi-layer board must be fixed to the floor of the structural floor with φ8 expansion bolts and fixedly connected to the ceiling wood keel. The weight must not exceed 30kg.

Light weight ≤ 2kg ,need to add wooden clogs when fixing.

Chandelier weight≤2kg

The weight of the lamp ≤ 4kg. When fixing the wood keel, the lamp base needs to be fixed to the wood keel with 3 self-tapping screws on each side.

When installing heavy chandeliers, a hook must be preset on the bottom surface of the structural panel, and the load-bearing rate of the hook should be determined according to the weight of the proposed lamp. Ultra-heavy lamps (> 8KG) and electric fans with vibration must be hung by themselves, and there must be no stress relationship with the ceiling.

Points to note when installing lamps

1. Downlights and quartz spotlights with a weight of less than 1kg can be directly installed on the light steel wood keel plasterboard ceiling decorative panel; lamps with a weight of less than 3kg should be installed on the secondary wood keel; lamps with a weight of more than 3kg should be directly hung on the building Load-bearing structure.

2. The chandelier itself has a certain length. Pay attention to the height of the floor when installing. When the floor height is ≥3m, you can choose chandeliers and ceiling lamps. For rooms with a floor height of 2.6-2.7m, the length of the installed chandeliers should not exceed 40cm.

When the floor height is less than 2.6m, you can choose a semi-chandelier or a pendant lamp with a diameter of 38 ~ 57cm to reduce the visual proportion.

3. When installing multiple chandeliers, pay attention to the position and length of the lamps. You can install the chandeliers at the same time as installing the ceiling, so that the position and height of the lamps can be adjusted based on the wood keel grille in the ceiling.

4. Pay attention to safety when installing lamps on the suspended ceiling. Generally, the ceiling used in the living room is relatively heavy. It is necessary to ensure that the ceiling is not damaged during installation and that the lamps do not fall off. The lamp should be fixed on the embedded hook or bolt, and the lamp cannot be installed directly on the ceiling wood keel.

5. The installation of the lamp must be installed in combination with the wall material to avoid the lamp being too close to the wall, which will cause direct light to the wall in the later stage, which will adversely affect the wall construction!
