A snap ring (a portmanteau of "circle" and "clip"), also known as a C-clip, Rotor Clip, circlip or Jesus clip, is a type of fastener or retaining ring consisting of a semi-flexible metal ring with open ends which can be snapped into place, into a machined groove on a dowel pin or other part to permit rotation but to prevent lateral movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a Shaft. Circlips are often used to secure pinned connections.

In the past 30 years, the building materials industry has formed a diversified investment pattern, with a number of leading and strong technologies in China Building Materials, Beijing Jinluo, Shandong Shanshui, Conch Cement, Taihang Cement, Taishan Gypsum and Knauf Gypsum Board (Tianjin). Under the leadership of domestic leading enterprises, private enterprises and joint ventures in various regions have developed rapidly, such as Lafarge Shui On, Jiangsu Huaer Run, Guangdong CSG, Hebei Huida, Guangdong New Pearl, Guangdong Dongpeng and other enterprises. Among them, China National Building Material Group, as a central enterprise, is China's largest comprehensive building materials industry group. The Group relies on the capital, technology and management advantages of central enterprises, and focuses on the development strategy of “big building materialsâ€, accelerates the pace of restructuring and promotes China's cement, glass and paper. Industry integration and structural adjustment of industries such as gypsum board. In the field of gypsum board, the industry integration and productivity strategic layout have been basically completed, and the production capacity has accounted for more than 40% of the country, becoming the leading enterprise in the domestic gypsum board industry. In the field of glass, the flat glass industry and the world's three largest float technology “Luoyang Float†represent the enterprise Luobo Group as the platform to carry out the integration of the flat glass industry. In the field of cement, successfully reorganized a number of cement enterprises in the Huaihai Economic Zone, and expanded and strengthened Zhonglian Cement Co., Ltd.; in the six provinces and one city of the Southeast Economic Region, a large-scale strategic reorganization of cross-regional and cross-ownership was carried out in a market-oriented manner. And built the largest cement manufacturer in the Southeast Economic Zone - Southern Cement.
At present, the sales of China's gypsum board and other products continue to increase, and a certain foundation has been established in the world building materials market. The products have covered more than 100 countries and regions, the structure of export products has been continuously optimized, and the export growth rate of high value-added and deep processing products has accelerated. The trade surplus has further expanded. Although it was also affected by the financial crisis, in the first 11 months of 2008, the export of gypsum products was 489,300 tons, an increase of 23% over the same period of the previous year; the export value was 142 million US dollars, an increase of 42.1% over the same period of the previous year.
However, the financial crisis has also brought certain impacts on the development of China's building materials industry. As trade protectionism rises, related issues are more likely to be infinitely magnified. For example, the “China Gypsum Board Event†is an industry event facing the current building materials industry. China's building materials enterprises should establish confidence, unite and actively respond with relevant departments, identify the causes, safeguard the legitimate rights and interests of Chinese products, and maintain the international reputation of Chinese products.
On November 10, 2008, the state introduced ten measures to expand domestic demand and promote economic growth. These major infrastructure constructions are closely related to the building materials industry. At the two national conferences in 2009, the government clearly stated that “expanding domestic demand, ensuring growth, adjusting structure, and promoting people's livelihood†as the focus of the country's work this year, and promulgating and implementing a series of effective measures. The person in charge of the China Building Materials Association told the reporter that in the future, the building materials industry will study and practice the scientific development concept through the joint efforts of the whole industry, focus on the development law, innovate the development concept, change the development mode, and unswervingly adhere to the industrial restructuring. Realize the development of building materials industry for a longer period of time, higher level and better quality.
China's building materials industry has developed rapidly in the 30 years of reform and opening up
The 30 years of reform and opening up have been the rapid development of China's building materials industry for 30 years, and advanced productivity has been greatly developed. Among them, the cement industry has achieved “low investment and localizationâ€, and the new dry process has been rapidly promoted. Since 1978, the gypsum board has been imported from abroad for the first time with an annual output of 20 million square meters of gypsum board production line. It has reached 1 billion square meters. Among them, a large number of building materials enterprises with strong financial strength are also making continuous efforts on the road of independent innovation, improving process technology and increasing production, and have achieved remarkable results.
