North America includes 23 countries, such as the United States, Canada, and Mexico. The steel structure markets in these countries are primarily based on American standards, with most of the implementation following U.S. steel structure guidelines. Additionally, the American Institute of Steel Construction (AISC) certification is one of the most authoritative system certifications in the world. It is a key indicator that a company's product production control meets U.S. quality management requirements and qualifies for the U.S. market. Henan D.R.Construction Group Steel Structure has held AISC certification since 2016 and obtained the Canadian Welding Bureau (CWB) welding system certification in 2017. It was the first company in Henan Province to achieve this certification, ensuring the competitiveness of its products in the North American market. With these certifications, the company has undertaken the Canadian hot-rolled steel plant renovation project and the Mexican steel box girder project, totaling more than 2,300 tons. It has accumulated extensive engineering experience in material procurement and welding process assessments for North American projects.
