ã€China Aluminum Industry Net】 The system of short standing edge aluminum-magnesium-manganese metal system The standing edge bite system is a 360-degree double-folding surface support roof system. The rib crown of the roof panel is closed with a mechanical lock, and the folded roof is completely Impervious and waterproof. Regardless of the shape of the building, it can fully engage the joints. There is no nail hole in the entire roof, which not only allows the roof to flex freely when the temperature changes, but also avoids the temperature stress, and eliminates the hidden danger of water leakage caused by the system screw fixation. Its special three-dimensional arc processing can be installed in different dome sizes. The outer plate of the roof is made of aluminum-magnesium-manganese alloy plate, and the connection is made by vertical occlusal connection. The roof system is connected to the main body in a floating manner, completely absorbing the displacement of the main body.

Its characteristics are: elegant and beautiful, the overall light and elegant, partial and smooth, adapted to a variety of architectural styles. The overall structure of the drainage and waterproof, the drainage slope of the double-biting of the standing edge should be greater than or equal to 10 degrees, and the drainage slope of the single-edged standing edge should be greater than or equal to 30 degrees. Three-dimensional curved arc-specific modeling easy processing.
The main features:
The structure is simple, light and safe;
Meet the requirements of architects and users for arc, spherical and three-dimensional curved arc and other special geometry roofing requirements;
The vertical height is small, the loss of aluminum plate is small, the system load is small, and the structural stability is high;
The system uses a combination of fixed fasteners and sliding fasteners to absorb the displacement caused by thermal expansion and contraction and prevent plate deformation or cracking.
System performance:
Fire Performance The fire resistance of roofing materials is very important. It relates to the safety of the general public and does not allow any insecurity. The materials used for the standing seam roofing system are non-combustible materials. In the event of an accident such as a fire accident, the roof system will not burn and no toxic gas will be produced. Therefore, the roof system provided by the company is completely reliable in terms of fire protection.
The energy-saving performance of the roofing system is very dexterous, and the system recommends the use of insulation wool. Energy-saving materials: It is recommended to use 100-thick aluminum foil insulation wool with good sound-absorbing and heat-insulating properties. This material is of great help to sound absorption, and can be fully paved without cold bridges. It is placed under the profiled steel plate and made of steel mesh. To support.
The acoustic treatment of the system is very important for the noise treatment of metal roofs. If it is not handled properly, it will have a detrimental effect on future use. Therefore, this system has done a lot of processing in terms of noise reduction: a multi-layer structure consisting of a panel, a flat plate, and a profiled steel plate on the roof, together with the sound absorption effect of the insulation cotton, the noise reduction performance of the roofing system will be much better than General roofing system. The roofing system has its unique treatment method to reduce indoor noise. A three-dimensional ventilation noise reduction screen set between the panel and the heat-ablated aluminum foil can achieve the effect of blocking outdoor noise, and can also play the role of ventilation. Excluding indoor agglutination condensate, three-dimensional ventilation noise reduction mesh is composed of reinforced modified asphalt membrane layer and polyamide composite ventilation material. It is a three-dimensional uniform nylon mesh mat, with various thickness, generally adopting 5-8mm. Thick as a roofing material.
The lightning protection roof system is closely connected with the overall lightning protection system of the structure, and the problems of lightning damage and electrostatic accumulation are fully relieved. The metal plates in the roof of the system are all good external maintenance system materials, and aluminum magnesium manganese alloys are good conductors. A single monolithic plate not only provides watertightness, but also is a good conductor, even if the overlapped area does not affect its lightning protection performance. The actual construction method is to hide and make a grounding under the roof panel every 6-10 meters in the vertical and horizontal direction of the metal roof, install a corner code at the grounding point, one head is fixed on the purlin, and the other head is fixed on the T-code bearing. The ground fixed on the purlin can be connected to the lightning protection system constructed by other units.
