Audited Supplier
Steel structure buildings have excellent mechanical properties, high steel strength, good toughness and ductility, can stably bear heavy loads, and ensure safety in disasters such as earthquakes.
Its construction is efficient, prefabricated in the factory and assembled on site, which greatly shortens the cycle and reduces equipment and manpower requirements. The space is flexible, and large-span column-free space can be achieved, and the layout can be adjusted conveniently in the later stage. It is also environmentally friendly and sustainable, with less construction waste and a steel recycling rate of over 90%, which is in line with the concept of green development.

In the production and construction process of steel structure buildings, modern process equipment is the core support for us to achieve efficient and high-quality delivery of projects. The automated cutting equipment is equipped with a CNC system with a cutting accuracy of ±0.5mm, which can accurately cut various types of steel to meet the needs of complex components and reduce material waste; the intelligent welding robot is equipped with intelligent sensing technology, and the welding speed is 3-5 times faster than manual work. The quality of the welds far exceeds the industry standard and can operate stably in harsh environments; the digital coating production line uses automated spraying equipment to accurately control the thickness and uniformity of the coating. The closed environment operation is both environmentally friendly and can improve the anti-corrosion performance of the steel structure by 5-10 years; the large crawler crane at the construction site has a maximum lifting capacity of 1,000 tons, and cooperates with the intelligent control system to ensure accurate and correct component installation.
Tiankai Southeast was jointly initiated by "Henan Tiankai Group" and "Zhejiang Southeast Grid Co., Ltd." (stock code: 002135). In August 2020, a strategic cooperation agreement was signed to establish Tiankai Southeast Green Building Technology (Henan) Co., Ltd. The first phase covers an area of 108 acres and has an investment of about 400 million yuan to create a production base with an annual output of 60,000 tons of steel structure processing capabilities.
Tiankai Southeast will use the steel structure and grid system technology and resources independently developed by Southeast Grid, share the top ten core technologies of Southeast Grid, more than 200 patented technologies and scientific and technological research and development results and academician workstations. It specializes in design, manufacturing, installation, prefabricated housing, multi- (super) high-rise steel structures, large-span space tube truss steel structures, plant steel structures, green building materials and other prefabricated building production and manufacturing enterprises.
The company's factory covers an area of 50,000 square meters, divided into four workshops, with 8 professional production lines, 58 cranes of various tonnages, a maximum lifting capacity of 50 tons, and a monthly production capacity of 6,000 tons. It mainly produces box columns, cross columns, round tube columns, welded H-beam columns, welded H-beams and box trusses, special-shaped giant steel structures, steel truss floor decks and other products.
We strictly control quality at every step and are committed to providing customers with high-quality and reliable steel structure products.
