As a joint-stock enterprise (formerly known as Shandong Valve Factory), we have been dedicated to the manufacturing of valves and valve cores for over 45 years. With a registered capital of 16.8 million yuan, covering an area of 60,000 square meters and a building area of 37,000 square meters, our company has experienced rapid growth since the restructuring in 2007. We are now fully capable of producing high-quality products that meet international standards, thanks to our skilled workforce, advanced technical equipment, efficient production processes, and well-equipped facilities. Our "Gaotian" tire valves are widely used in inner tubes, tubeless tires, and tire rims across various vehicle types.
We currently produce multiple series of valves, with nearly 100 different types, totaling over 200 million sets annually. In addition, we manufacture 8,000 tons of valve copper each year. Our commitment to quality and innovation is reflected in our certifications, including ISO/TS16949:2009 from ISR in November 2011, ISO9001:2008 from Beijing Zhongrun Certification Co., Ltd. in September 2013, and CE certification from National Quality Assurance (NQA) in March 2014.
Guided by the quality policy of "quality-oriented, honest and credible; continuous improvement, customer satisfaction," and the business philosophy of "tolerance, innovation, and integrity," we strive to build long-term partnerships with domestic and international customers, working together toward mutual success. Our goal is not only to deliver superior products but also to provide exceptional service and support to meet the evolving needs of the market.
Greenboard Steel
One of the main advantages of greenboards is their durability. The steel sheet base material is strong and long-lasting, while the green coating is resistant to scratches, stains, and other types of damage. This makes greenboards a good choice for high-traffic classrooms where the writing surface may be subject to frequent use.
Greenboards are also easy to clean. The non-porous surface can be wiped clean with a damp cloth or eraser, making it quick and easy to maintain. Additionally, the green color of the board provides a high contrast for writing with chalk or markers, making it easy to read from a distance.
Another advantage of greenboards is that they are less reflective than whiteboards, which can reduce glare and eye strain for students and teachers. The matte finish of the green coating also provides a more natural writing surface, which some people may prefer over the smooth, slippery surface of a whiteboard.
Overall, greenboards are a popular choice for schools due to their durability, ease of cleaning, and high contrast writing surface. While digital whiteboards and other high-tech tools have become more common in some schools, greenboards remain a reliable and effective teaching aid in many classrooms.
