The core competitive advantage of this soundproof partition keel is its professional acoustic optimization design. The C-shaped cross-section with widened flanges forms a sealed sound insulation cavity, which can effectively weaken the transmission of impact sound and air sound. The reserved 15mm-wide sound insulation cotton slot can be filled with glass wool or rock wool, further improving the sound insulation performance by 8-10dB. The 6063-T5 aluminum alloy material has good extrusion forming performance, ensuring consistent product dimensions and structural strength. The anodized surface treatment forms a dense oxide film, which has excellent corrosion resistance and does not release harmful substances, meeting the indoor environmental protection requirements of medical and educational places. The standardized mounting holes and matching connecting accessories realize quick assembly, reducing on-site construction time by 40% compared with traditional partition keel installation methods. It has passed the Class A2 fire rating test, meeting the fire safety standards of commercial buildings.
The product has a standard length of 3600mm, with optional thicknesses of 1.0mm, 1.2mm and 1.5mm. The C-shaped cross-section has a web height of 75mm, flange width of 30mm, and the inner slot width of 15mm for sound insulation cotton installation. The material is 6063-T5 aluminum alloy, with tensile strength up to 160MPa and yield strength up to 110MPa, complying with ASTM C754 and EN 1716 building partition material standards. The anodized silver gray surface treatment has a film thickness of 10-15μm, with excellent scratch resistance and corrosion resistance. The dimensional tolerance of the keel is ±0.3mm/m, ensuring the flatness and verticality of the partition wall. The products are packed in plastic woven bags with moisture-proof treatment, with 15 pieces per bag, with a total net weight of about 68kg. The supporting connecting pieces and screws are sold separately, forming a complete partition installation system.
It is suitable for various indoor partition projects requiring high sound insulation standards, including office building tenant partitions, hotel guest room partitions, KTV rooms, recording studios, school classrooms and hospital wards. It can be matched with various partition panels such as gypsum board, calcium silicate board and fireproof board, forming a complete partition system. It is especially suitable for commercial places with high sound insulation requirements, such as conference centers, exhibition halls and entertainment venues. The installation process does not require complex welding operations, and the modular connecting pieces can realize quick positioning and fixing, reducing the technical requirements for on-site construction workers. The environmentally friendly surface treatment meets the indoor air quality standards, and will not cause secondary pollution to the indoor environment.
