Residential Sectional Garage Door
A typical version of an overhead garage door used in the past would have been built as a one-piece panel.The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The door is balanced by either a torsion spring system or a pair of extension springs.A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security
• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.

According to reports, Zhengzhou United New Materials Co., Ltd., located in Zhengzhou Economic and Technological Development Zone, started construction of the first phase of the project. The total investment of the project is 30 million yuan, covering an area of ​​23,000 square meters. It was completed at the end of December this year. At that time, the company will produce nano diamond-based deep-processed products such as nano-diamond slurry and nano-diamond polishing film, which will be widely used in hard disk, magnetic head, fiber-optic ceramic plug, chip and other precision elements. Surface processing of the device. The company's development and implementation of this new product has filled the domestic gap, and at the same time it can break the technological monopoly of foreign companies on China's precision polishing materials.
This is also an initiative to lengthen the industrial chain - Henan Province United Abrasives Co., Ltd., the parent company of Zhengzhou United New Materials Co., Ltd., independently developed the explosive synthesis of nano-diamonds and nano-polycrystalline diamond products, and the company is also domestic. The first company to successfully implement the industrialization of such products.
It is also known that compared with ordinary synthetic diamond, nano-diamond has better physical and chemical properties and higher added value. At present, only a few countries such as Russia, the United States and China can produce nanodiamonds internationally.
Attachment: Henan Province Joint Abrasives Co., Ltd. Henan Province Abrasives Co., Ltd. was established in 2003. A private enterprise specializing in the research, development, production and operation of micro, sub-micron and nano-sized superhard materials and related products. The company is located in Zhengzhou Economic and Technological Development Zone. It is a high-tech enterprise approved by the Science and Technology Department of Henan Province, a technological innovation integrity enterprise in Henan Province, and a high-growth high-tech enterprise in Zhengzhou. The company has two branches, Zhengzhou United New Materials Co., Ltd. and Zhengzhou United Energy Electronics Co., Ltd., and three production branches in Jiaozuo, Nanyang and Zhengzhou High-tech Development Zone. The company's assets have grown from the initial establishment of 3 million yuan. The current 80 million yuan, the total number of employees is 120.
The company vigorously implements the strategy of developing enterprises through science and technology, develops high-tech products as the enterprise goal, attaches importance to the absorption and cultivation of enterprise talents, and carries out technical cooperation. It has established stable technical cooperation with many institutions of higher learning and research institutes such as Beijing Chunchang Institute of Ceramics and Materials, Wuhan University of Technology, Zhengzhou University and Henan University of Technology. At present, the company has a total of 45 professional and technical personnel, accounting for 37% of the total number. Among them: 3 professor-level senior engineers, 5 doctoral students, 10 master students, and 27 other professional and technical personnel.
The company's products are mainly based on powder superhard materials and related products, including single-crystal, polycrystalline, nano-scale ultra-fine diamond micro-powder of all sizes from 125 microns to 40 nanometers. The products are of stable quality, advanced technology and well-equipped. At the same time, they have standardized production and test bases as well as international leading powder testing equipment. The company has independently developed an explosive method to synthesize nano-diamonds and nano-polycrystalline diamond products, and has become one of the domestic enterprises that implement industrialization of such products.
The company attaches great importance to market development, and sets up sales companies in the United States and Shanghai respectively. The products are 100% sold to the international market and are well received by customers in Europe, Japan and the United States. The products have attracted wide attention in the international superhard materials industry with their unique performance.
In the development, the company always pays attention to the expansion and extension of the industrial chain and takes the road of group development. Established two branches in 2005 and 2006 respectively, with Zhengzhou United Materials Co., Ltd. as the main body, focusing on the development of nano-diamond-based deep processing products - nano-diamond polishing liquid, nano-diamond polishing film, products applied to hard disks, The surface processing of magnetic heads, fiber-optic ceramic ferrules, chips and precision components, the development and implementation of new products can save a lot of foreign exchange for the country, and can also break the foreign technology monopoly of precision polishing materials; with Zhengzhou United Energy Electronics Co., Ltd. as the main body Focus on the development of energy-saving products targeting solar cells, as well as the development and production of various types of rechargeable batteries and charging control devices. Currently, the self-developed mobile solar system has applied for national patents, and the products can be put on the market in the near future. While carrying out scientific and technological research and development, the company pays great attention to the protection of intellectual property rights. At present, it has applied for 9 patents, of which 4 have obtained patent protection.
During the “Eleventh Five-Year Plan†period, the company plans to invest 160 million yuan, add 4 sets of dynamic pressure nano material synthesis equipment, 30 sets of static pressure synthesis equipment, 3 polishing liquid production lines and 2 polishing film production lines; realize new solar cell production line. Industrialization, the acquisition of 30 sets of test equipment. At the same time, we will continue to increase product research and development efforts, set up a research center for nano-diamonds and their products, and strive to have a place in the world of precision super-hard materials.
