Twelfth Five-Year Plan building security door price / Jiangxi national security door manufacturers intensified energy conservation and introduction of the relevant rules, in this case, imitation copper industry to speed up technological innovation, product upgrades, improve quality pace, to the community launched a large variety of new environmentally friendly energy-saving products, so that the industry has been an unprecedented development. Several years ago, Chinese building windows and doors industry is small scale, technology and equipment times, low product quality status. For energy-saving windows and doors market, it has an engineering focus, invested a large amount of features, requires companies to have a relatively high design capability, exquisite processing technology and sophisticated construction technology, these small-scale enterprises for the formation of financial barriers. The large enterprise, with its deep strength and good reputation advantage quickly occupied a large market, highlighting the advantages of scale. Although China's energy imitation copper industry has been considerable development, but compared with the market demand, some problems still exist, the main manifestation has two aspects: First, the product of weather problems, the second issue is cost. All-weather product refers to adapt to different climatic conditions Chinese vast geographical requirements imitation copper products, can meet the northern winter heat, summer heat requirements, but also meet the standards southern coastal areas of anti-seawater corrosion and sunlight. Refers to the cost problem of how to get more into the new energy-saving imitation copper products currently still live in the old house where the ordinary people at home. Energy-saving imitation copper has now reached around the building energy efficiency design standards imitation copper product ratio is about 50%. At the same time due to the energy-saving technology products imitation copper content than ordinary products, the national quality inspection department of supervision and inspection efforts large "roadside shop" and "guerrilla" good reasons to follow suit, leading to the current value of energy-saving products Imitation copper much higher than ordinary products. Generally qualified energy-efficient windows and doors products margins between about 12% -15%, compared to less than 5% profit margin traditional products for doors and windows, energy-saving windows and doors is clearly more favored by the business. Therefore, in recent years many have a certain strength of profiles manufacturers and Fenestration companies have joined the energy-saving windows and doors industry in the past, so that the industry is expanding. So why windows ruled it? We know that because the building needs lighting, ventilation, easy to staff a person, so it is installed on the doors and windows, but after installing windows and doors, wind, rain, mosquitoes and easily invaded by interior doors, which requires structural doors contains open fan and translucent materials. Us on has preserved ancient buildings visible, then the window lattice points, and this was because the light-transmitting material is paper doors and windows, if the sub-grid is too large, the windows of paper is easily broken, and therefore the main object of the sub-grid is supporting translucent material; the 19th century, as a translucent material such as glass windows, doors and windows of the sub-cell size increased significantly, to the 20th century, the use of glass thickness from 3 mm to gradually increase to 5 to 12 mm, thickness and sometimes tens mm, especially glass appearance, making the main purpose of sub-grid of windows and doors by supporting translucent material into the ventilation, cell size is mainly composed of open ventilation fans to decide. After the beginning of this century, more and more high buildings, and with the widespread use of air conditioning and window profiles section increases, the thermal insulation of windows and doors put on top of its function, and therefore the requirements of sub-grid doors and windows as possible, its purpose mainly to meet the glass windows and doors component itself has enough wind pressure strength, if the building is no glass washing facilities or when considering outdoor cleaning glass is not easy for easy cleaning glass and sub-grid. If you observe, is not difficult to see that there is a big difference though all the doors and windows during the sub-grid mode. But all follow a common basic principle that the ideal is not random sub-grid windows, doors Co., Ltd. Yongkang days ___ building security door price / Jiangxi security door manufacturer
