Gujian Robotics

杭州固建机器人科技有限公司

Gujian Robotics (Hangzhou Gujian Robot Technology Co., Ltd.) is a Chinese construction-robotics company that develops welding robots, robotic workstations and automated production lines for building steel structures and related heavy fabrication. The company was registered on 30 July 2018 in the Xiaoshan Economic and Technological Development Zone, Hangzhou, Zhejiang Province, with Qiu Tian as legal representative. Its official website describes the business as robot technology, machine vision, industrial internet of things and artificial intelligence applied to steel-structure production, climbing-frame welding, building-materials production data management and smart steel-structure factories, and names the company's robot brand Gu Jian Robot.

Background. According to company profiles published in 2020, the founder started robotics work at the Hong Kong University of Science and Technology in 2008, joined the robot control system R&D and industrialisation team at Googol Technology (Shenzhen) in 2010, and in 2013 co-founded Foshan Googol Automation Technology with Googol Technology and the Foshan research institute of Guangdong University of Technology, focusing on welding-robot system integration. Core team members are described as coming from HKUST, Zhejiang University, Hunan University and Central South University, with expertise in motion control, mechanical design, construction technology and steel structures. The company reports a headquarters and market centre in Hangzhou, an R&D base in Shenzhen, a mechanical manufacturing base in Foshan and an engineering implementation centre in Changsha.

Products. Gujian's current flagship is a dexterous welding robot marketed with the line that it lets beginners weld easily. Trade coverage in 2026 describes it as a portable robot arm that mounts on large workpieces through a strong permanent-magnet base, so it can work on vertical, overhead and inverted steel surfaces. Operators teach weld paths by dragging the torch by hand rather than programming, then choose the weld type (for example fillet or groove) on a tablet, with parameters drawn from a cloud welding-process library built with the Zhejiang Baidun Welding Technology Research Institute. Target markets named are steel structures, bridges, shipbuilding and nuclear power equipment; the company reports one customer purchase of more than 50 units and a shipbuilding case where welding efficiency more than doubled. These figures are company claims.

Earlier products are fixed robotic welding workstations and automated lines for climbing-frame guide rails, walkway plates and safety frames used on building sites, covering material handling, cutting and welding with rotating positioners, automatic torch cleaning and a central control system. A BIM-driven construction steel-structure production line developed with Zhejiang Construction Engineering Group was listed in Zhejiang Province's 2019 key R&D plan and as a 2020 provincial digital smart factory, and the company's welding systems were deployed for China Railway No. 2 Engineering Group on the Peiying Jinxiucheng project.

Intellectual property. A 2020 company profile listed 4 invention patents, 24 utility-model patents and 4 software copyrights; a 2025 industry list article cites 9 invention and 33 utility-model patents.

Ownership. Business-registry data shown on 36Kr list two shareholders, Shanghai Jiante Big Data Technology Center (limited partnership, 70%) and Qiu Tian (30%), and no external financing rounds.
