Extruded aluminum foil composite duct Specifications: 3 m * 1.2 m * 2 cm (2.5) thickness can choose! 4 m length can be customized to produce or longer! Width is 1.2 meters wide Features: compression and strong, good construction, transportation convenient, good repair, ease of maintenance and high cost! First, the product name: extruded duct Second, product specifications: 3000 * 1200 * 20mm (Remark: Length processing) Third, the product description: extruded aluminum foil composite duct is widely used as a composite duct, it Double-sided embossed aluminum, the core material is flame retardant polystyrene foam disposable processing, the indicators in line with the national standard GB50423-2002 "Construction Quality ventilation and air conditioning engineering acceptance" and GB50045-95 "fire protection design of tall buildings specification. " Fourth, the product application: extruded aluminum foil composite duct is widely used in food processing, machinery manufacturing, electronics technology, textile companies and other places. V. Features: 1, economic and environmentally friendly products and low cost, chemical stability, will not mildew or decomposition, do not evaporate harmful substances. 2, light and durable goods inside as an independent bubble-enclosed structure, external embossed aluminum foil, with a high compression, non-absorbent, moisture-proof, airtight, low thermal conductivity, durable insulation, long life performance. 3, insulation performance is good product can effectively prevent the emergence of condensed water, protection from the indoor unit and ceiling condensation problems, but also has a higher energy effects. 4, the product looks nice variety of colored paint can be painted, decorated with requirements. 5, making maintenance simple and convenient products in the fabrication and installation of the construction site, just use simple special cutting tools, hand plastic forming, flanged combination of steel and accessories lifting with simple, light, and therefore, less labor, progress quickly save labor costs, reduce construction risks. Growth during use, any one, if damaged, can be free to cut the adhesive patch, maintenance very convenient.
