Henan Yanding Steel Structure Engineering Co., Ltd.

Henan Yanding Steel Structure is a professional company focused on the production and research & development of LED display screen steel structures. The company was founded in 2014, and prior to that, the team had accumulated extensive on-site fabrication and design experience with LED large-screen steel structures. The company has senior welders and professional engineers. After years of practical exploration, and in collaboration with several experts from the Design Institute of Zhengzhou University, the company successfully developed in August 2019 a complete standardized production and installation solution for LED large-screen steel structures. This solution introduced the classic mortise-and-tenon technique, which is widely used in the LED structure field in China. The application of this technique is of milestone significance to the LED large-screen steel structure industry. It strongly promotes the overall quality of LED displays, enhances the core competitive value of products, and improves customer satisfaction. Our company holds four patents for mortise-and-tenon welding-free steel structures. These are professional certification documents issued by relevant national authorities to enterprises that meet technical standards. The certificates are mainly for construction companies combining traditional mortise-and-tenon techniques with modern steel structure technology, proving their capability in designing, producing, and constructing welding-free steel structures. Our company also has a mortise-and-tenon structure inspection report. This inspection report provides a comprehensive assessment of welding-free mortise-and-tenon steel structures, ensuring their safety and reliability. The inspection covers key indicators such as structural strength, connection stability, and durability. All tests are conducted according to national standards, and the results meet industry requirements.
