The materials of grille ceiling are plastic, aluminum and iron. The smaller the spacing, the higher the price, of which plastic is the cheapest and aluminum is the most expensive.

grid ceiling specifications: the standard is 11mm or 15mm, and the heights are 41mm, 61mm and 81mm.

the grid size of aluminum grille is 51 x 51 mm, 75 x 75 mm, 111 x 111 mm, 125 x 125 mm, 151 x 151 mm and 211 x 211 mm respectively.

the normal specifications and dimensions of sheet grating are: 11*11mm, 15*15mm, 25*25mm, 31*31mm, 41*41mm, 51*51mm and 61*61mm.

Grille ceiling lamps can be installed in ceilings, and are widely used in large shopping malls, restaurants, bars, waiting rooms, airports, subways and other stations, which are elegant and beautiful and last as long as new. It is one of the commonly used ceiling materials for decoration companies and is well received by customers.

Grille ceiling construction process:

1. Derrick-spring the ceiling elevation line-brush black paint above the elevation line-install water, electricity and ventilation pipes-install the surrounding mineral wool board ceiling-initially install the metal grille-set the arch position and height of the ceiling-

2. Find rules for the plane position of ceiling: Because the shopping malls on each floor are 1.21 m long from east to west, 34.7m wide from north to south, and the spacing between columns is 8.1m*8.1m, the vertical or parallel relationship between metal grating and mineral wool board, ceiling, ceiling and wall and column must be properly handled. Therefore, the relevant axes should be measured to the facade of wall column, and the rules for plastering should be found according to this datum line, so as to ensure the wall. Take this as the datum of the plane position of the ceiling.

3. Form and height of arching of grid suspended ceiling: This project is not suitable for arching because its longitudinal dimension is too long. The arching should be in the short north-south direction, and the arching height can be about 1/211 of 8m column spacing. The plane position of the fire-fighting spray head should not coincide with the grating strip, and both directions should be straight. For this reason, a pedal bend greater than 911 can be made at the upper end of the fire-fighting sprinkler riser to fine-tune the plane position of the spray head.

4. Retention of equipment inspection holes: Because all kinds of pipes in the grille ceiling are equipped with regulating valves, inspection holes must be retained at corresponding positions, and the inspection holes are not in vertical and horizontal rows. For this, the following methods can be adopted: firstly, cut into holes, then add corner aluminum around the holes (the corner aluminum is painted with the same color as the grille first), and the corner aluminum lower skin is recessed into the grille lower skin by 2mm. Finally, adjust and assemble the grille strips cut from the holes and put them on the corner aluminum.

5. Joint treatment between the ceiling and the column: L21mm*21mm angle aluminum can be used for the connection with the square column, which can achieve the effect of coordination with the keel of the ceiling edge of the mineral wool board, and the connection with the column can be closed by φ 35 stainless steel pipe ring edge.
