Aluminum grille ceiling construction technology
Aluminum grilles have become a popular ceiling material in recent years, offering an open view, good ventilation, and a clean, modern appearance. Their neat lines and clear hierarchy make them ideal for contemporary interior designs. They are easy to install and remove, which has made them a top choice in the decoration market. Aluminum grilles can be divided into two main types: grooved and flat, each suitable for different design needs. The installation process begins by determining the ceiling height using a laser level or water level. Marking the wall with a chalk line ensures accuracy. Next, iron expansion bolts are used to fix the ribs on the ceiling, and light steel keels are installed beneath them to maintain a level surface. If the span of the grille is less than 3 meters, no additional support is needed. Then, aluminum corner profiles are fixed along the horizontal line using cement nails. The aluminum grilles are assembled on the ground before being lifted into place. Once assembled, they are secured to the aluminum angle iron, with a thin wire connecting the middle section directly to the light steel keel for stability. When marking the layout, a water level is used to copy the horizontal points on all walls and corners. If the walls are long, additional points should be marked. A level line is then created from the reference line to the desired ceiling height, using a chalk line along the walls. This forms the base of the grid structure. Main keels are also marked from the center of the ceiling outward, spaced about 1000 mm apart, with fixed points every 900–1000 mm. Additional supports may be added if there are beams or pipes that require more secure fastening. Hanging rods are fixed using expansion bolts. A 6mm rod is commonly used, and the rods can be made from cold-drawn steel or coiled steel, though the latter must be straightened mechanically. One end of the rod is welded to an L-shaped corner bracket, with the hole size matching the rod and bolt diameter. The other end is threaded or attached using a pre-made hanger. All rods must be rust-proofed before installation. Holes are drilled into the ceiling using an impact drill, slightly larger than the expansion bolt diameter. Light steel keels are then hung from the rods. For lower ceilings, this step can be skipped. Standard 38mm light steel keels are typically used, spaced 900–1000 mm apart. They should be installed parallel to the room's walls and arched at 1/200 to 1/300 of the room’s span. The overhang of the keel should not exceed 300 mm; otherwise, additional supports are required. Main keels are joined end-to-end, with adjacent joints staggered for stability. After installation, the keels should be roughly levelled. If the suspended ceiling exceeds 15 meters in span, a large keel must be added every 15 meters to the main keel, and vertical keels must be securely welded. Spring plates are then connected to the light steel keel using suspension wires, spaced 900–1000 mm apart. The spring clips are then attached to the hangers. Main and secondary grids are pre-assembled according to the design plan. Finally, the finished grille ceiling is placed into the main keel opening using a hook and lifted into position. Once fully installed, the ceiling is adjusted to ensure it is level and properly aligned.
