Who We Are
Shangqiu Factory, Export Team
Henan Laotie Steel Structure Engineering Co., Ltd. (河南老铁钢结构工程有限公司) manufactures steel structures in Shangqiu, Henan. The company was registered on 21 October 2025. Our team has 15+ years of export experience, with projects in 30+ countries.
The Shangqiu factory runs 5 production lines with a combined output of about 5,000 metric tons a month. From raw steel plate to fully fabricated, surface-treated, and trial-assembled steel structures — every step happens under one roof, ensuring complete quality traceability.
International sales are handled directly from our Shangqiu factory, so buyers deal with the people who make their steel. All products are CE (EN 1090), TÜV and ISO 9001 certified.
Our in-house engineering team uses Tekla Structures, SkyCiv, and PKPM to deliver code-compliant structural calculations and detailed fabrication drawings for every project — whether it's a 500 sqm workshop or a 30,000 sqm logistics center.
