Aluminum grilles on the facade and ceiling
Aluminum grilles are a primary decorative material in many large-scale projects, mainly used for building exteriors and ceiling finishes. Their main structure, consisting of main and secondary ribs arranged in a grid pattern, alleviates the oppressive feeling caused by other closed ceiling structures, creating a continuous, flat visual effect and a structurally sound appearance.
Let's take a closer look at aluminum grilles.
I. Product Classification
Aluminum grilles are mainly divided into flat aluminum grilles and recessed aluminum grilles.
Recessed aluminum grilles are similar to flat aluminum grilles and are made from high-quality aluminum.
The difference is that recessed aluminum grilles are larger than flat aluminum grilles and have a groove of about 1 cm at the bottom, hence the name recessed aluminum grilles. The wider bottom of recessed aluminum grilles gives them a stronger three-dimensional effect and also provides good rigidity, making them less prone to deformation.
II. Material Properties & Performance:
Aluminum grilles, through specific shaped units and their combinations, allow for both concealment and transparency in interior ceiling finishes. The grilles are arranged vertically, horizontally, and diagonally, and are integrated with lighting fixtures, enhancing the overall artistic effect of the finish. They possess the following characteristics:
Create an open space, facilitating the arrangement of ventilation facilities and fire sprinklers without affecting the overall visual appeal;
Use high-quality aluminum alloy sheets, compatible with exposed grid systems;
Uniform color; guaranteed for 10 years for indoor use without discoloration;
Simple and convenient installation and disassembly; secure connections; each grille can be repeatedly disassembled and reassembled for easy maintenance;
Easily compatible with various lighting fixtures and devices; can be combined with downlights and fluorescent lights, and assembled according to actual needs for excellent results;
Highly consistent height, neat arrangement, clean and orderly lines, and distinct layers, giving a clean and spacious feel, avoiding dullness and monotony.
III. Precautions:
Aluminum grilles can be mainly divided into recessed aluminum grilles and flat aluminum grilles. Due to the large area of each floor, the vertical and parallel relationships between the metal grid and the mineral wool board, and between the ceiling and the walls/columns, must be carefully addressed. To this end, relevant axes should be transferred to the wall/column facades, and plastering should be done according to these baselines, ensuring that the wall surfaces are parallel to the axes and that adjacent surfaces are perpendicular to each other. This serves as the reference plane for the ceiling position.
Arching form and height of the grid ceiling: The arching height can be approximately 1/200 of the 8 m column spacing.
Because various pipes within the grid ceiling have regulating valves, inspection holes must be provided at the corresponding locations. The plane position of the fire sprinkler heads must not coincide with the grid strips, and both directions should be straight. Therefore, a step bend greater than 90 degrees can be made at the upper end of the fire sprinkler riser to allow for fine-tuning of the sprinkler head's plane position.
Provision of equipment inspection holes: Because various pipes within the grid ceiling have regulating valves, inspection holes must be provided at the corresponding locations, and the locations of these inspection holes are not necessarily aligned in a straight line.
The following method can be used to address this: First, cut holes, then add angle aluminum around the holes (the angle aluminum should be painted the same color as the grid). The bottom edge of the angle aluminum should be recessed 2 mm from the bottom edge of the grid. Finally, adjust and assemble the grid strips cut from the holes and place them on the angle aluminum.
Treatment of joints between the ceiling and wall columns: For connections to square columns, L20mm × 20mm angle aluminum can be used to achieve a consistent effect with the edge keel of the mineral wool board ceiling. For connections to round columns, a ￠35 stainless steel pipe can be used to enclose the edge.
The ceiling, composed of a continuous combination of grids, has distinct layers and a strong three-dimensional effect.
