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.

What should I do if the pool pump is clogged?
As the best place summer summer swimming pool, swimming pool safety and health is also more and more important. Swimming pool pump sometimes blocked, how to deal with it? Why swimming pool pump anti-clogging performance of the pump more and more attention, there are two main reasons: First, the cost of swimming pool water treatment increases. Industrial companies are working to reduce the water consumption per unit of production, which makes the sewage solids and fiber content is higher and higher. Second, sewage pumps are increasingly using energy-saving measures, that is, speed regulation drive, and speed regulation can not guarantee that the pool pump will not be blocked. For the frequent blockage of the pump impeller problems, the initial operation of the swimming pool equipment will be used every block will be Qing, blocking the overnight approach. Although this avoids downtime, but often disassemble the pump body, resulting in increased wear and tear of the pump orifice ring and other components at the same time each block costs a lot of manpower. In order to change this kind of situation, install the carbon steel to reject the dirty box in the water inlet of the pump, and has 45 degree inclination. Filter inside the box to filter impurities again to avoid blockage. Monthly team on the pollution 1 to 3 times the pollution. Swimming pool pump rotor blade morphology is divided into two kinds, respectively, the swirl blade and cutting blade, the blade of these two forms is the most widely used. The swirling impeller does not move in the medium being transported, guides the medium to be pumped into the pump chamber according to the principles of fluid dynamics, and the pumped medium flows by the impeller. In this way, long fibers or solids in the pumped liquid medium are also pumped out together. The cutting blades, can be a large block of solid material chopped, so no longer blocked. In addition to being over clogged, precautionary efforts are also important. Routine maintenance of pool pumps: Check and regularly clean the batter baskets. When cleaning, do not knock the batter. Washbasin if damaged, should be promptly replaced; regular inspection pump head seal. If there is any damage, please replace it in time; keep the motor clean, keep the motor air outlet unobstructed; Occasionally, the motor shaft seal will be worn, should be promptly replaced; Winter should clear the pump head water, clean the pump inside and outside, Store the pump in a dry and well-ventilated room. High anti-blocking performance Swimming pool pump can make the swimming pool water treatment better, reduce labor costs.
