Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.

Distributed energy generation is the energy development mode that best reflects the advantages of energy conservation, emission reduction, safety and flexibility. The “12th Five-Year Plan†clearly proposes to promote the promotion and application of distributed energy systems. It is reported that the "Distributed Power Generation Management Measures" formulated by the National Energy Administration has entered the stage of soliciting opinions. The method will be introduced as soon as July, and will be sold to the grid through fund subsidies, redundant power grids, and property rights granted to investors. Measures to stimulate the development of distributed energy. This marks the biggest obstacle to the development of distributed energy will be cleared. Multi-support measures to stimulate development It is understood that the main forms of distributed energy systems include: gas cooling and heating triple supply, waste power generation, biomass power generation, small hydropower, small photovoltaics and wind power. In terms of project construction, the "Measures" is expected to fully open the planning, design, investment, construction, operation and other aspects, allowing distributed generation grid-connected access point user-side facilities. The so-called distributed generation refers to the power generation system or multi-connection system that is built in the vicinity of the user and the surplus power is sent to the local distribution network in addition to the self-use. Its main feature is that multi-purpose new power generation technology is beneficial to environmental protection; energy utilization efficiency is high, up to 60-90%; power supply capacity is small, voltage level is low; close to load center, access to distribution network; flexible operation mode, networkable Can not be connected to the Internet; electricity safety is more reliable than centralized power generation, and the probability of power outage is small. In addition, it can also solve the problem of power supply in remote areas. The reporter learned that the key to distributed generation is the operation and subsidy policy. In operation, distributed power generation is preferentially self-sufficient, and excess power can be used to access the Internet and sell electricity to the grid. In the subsidy policy, subsidies for electricity subsidies or subsidies for project construction funds will be adopted. For the self-sufficient self-use of electricity, the starting point of the subsidy for electricity is the level of the sales price actually paid by the user. For the part of the excess electricity, the starting point for the subsidy for electricity is the on-grid price of local desulfurization coal-fired power. In this regard, Han Xiaoping, an energy expert who has long tracked the development of distributed energy, believes that after ten years of gestation, distributed energy will usher in an outbreak. "The Fukushima nuclear power leakage incident and the emergence of off-grid accidents in domestic wind power bases have made the importance of distributed energy prominent, which has become the key to solving the problem. With the increase of natural gas supply and the solution of grid-connected problems, the development of distributed energy is developing. At this time, this has become the consensus of the Energy Bureau, enterprises and society.†According to relevant sources of the Energy Bureau, distributed energy is a major measure to rationally control the total energy consumption. “If the distributed power generation reaches 5% of the existing power generation capacity, it can replace 70 million tons of standard coal, which is equivalent to the construction of 64 large-scale coal-fired units of 600,000 kilowatts.†According to the introduction, China’s energy utilization rate is only 33% is about 10% lower than that of developed countries; China's energy consumption per unit of GDP is 2.5 times that of the United States, 5 times that of the European Union, and 9 times that of Japan. As a result, China is facing tremendous pressure on energy conservation and emission reduction, and expanding the development and utilization of distributed energy is one of the breakthroughs. Installed capacity is expected to increase tenfold in ten years. It is worth noting that developed countries have effectively promoted the development of distributed energy through planning guidance, technical support, preferential policies, and the establishment of reasonable price mechanisms and unified grid-connected standards. The CICC research report said that the government's removal of grid-connected barriers and subsidies will stimulate the rapid development of natural gas distributed energy. These obstacles are about to be cleared, and now the grid connection and subsidy issues will be resolved through the introduction of the Measures. In August 2010, the State Grid has formulated the “Technical Regulations for Distributed Power Access to Grids†to clear the barriers for distributed generation access to the grid from a technical perspective. From the perspective of foreign countries, the proportion of distributed energy in developed countries is quite high. Distributed energy generation accounts for 53% of the total in Denmark. Germany's distributed generation installed capacity reached 20%, with Japan and India reaching 14% and 18% respectively. There are more than 6,000 distributed energy stations in the United States, accounting for 7.8% of the total installed capacity, mainly based on natural gas combined heat and power and combined heat and power. The development of distributed energy in China is just beginning, and there is huge room for improvement. Taking natural gas distributed generation as an example, the current installed capacity is about 5 million kilowatts, less than 1% of the country's total installed capacity. In April 2010, the Energy Bureau proposed to build 1,000 natural gas distributed energy projects by 2011; to promote the use of distributed energy systems in large cities by 2020, with an installed capacity of 50 million kilowatts, a tenfold increase from 2010.
