Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.

During the CIMT2011, the Japan Machine Tool Industry Association held a press conference on the macroeconomics, machine tool industry trends and the Great East Japan Earthquake. Nakamura Kenichi, president of the Japan Machine Tool Industry Association, pointed out that "the order value of the Japanese machine tool industry exceeded 1 trillion yen for five consecutive years from 2004 to 2008, but due to the financial crisis, the order amount in 2009 was only 411.8 million yen. In the past 30 years, in 2010, in the context of strong demand from Asian countries such as China, the total amount of orders reached 978.6 million yen, up more than 130% year-on-year, of which export demand rose by 166% to 671.1 million days. Yuan, returned to the fourth level of history.†Nakamura Kenichi expects that the order amount in 2011 will reach 1,100 billion yen, up more than 12.4% year-on-year. According to data released by the Japan Machine Tool Industry Association, in February 2011, Japan received orders from Asian countries at 45.66 billion yen, a record high for two consecutive months. Orders from China's motor, automobile and general machinery industries were active, and China's orders accounted for 40% of Japan's total exports. At the same time, the North American market has seen a clear recovery trend. Regarding the impact of the Japanese earthquake and tsunami incident on the airport industry, Nakamura said that most machine tool manufacturers are located in the central and western parts of Japan, and the direct damage to the machine tool industry is not serious, and the impact on overall production is relatively light. However, due to tight power supply, Japan will adopt power-limiting measures, while domestic gasoline and other fuel supply is insufficient, which may bring inevitable indirect losses to the machine tool industry.
