Product Description
Our prefabricated steel structure buildings are designed for efficient construction and overseas project delivery. Steel components, including columns, beams, end plates, and connection assemblies, are prefabricated in our factory according to approved engineering drawings. Components are clearly identified, organized, and packed for export to facilitate on-site assembly.
The building system primarily uses bolted connections, helping reduce on-site welding, simplify installation, and minimize construction activities at the project site. Depending on project requirements, wall and roof insulation systems, doors, and windows can be customized to meet functional and local building requirements.

- Factory-Based Manufacturing: Controlled production processes help maintain consistent fabrication quality and dimensional accuracy.
- Reduced On-Site Work: Factory-prefabricated components help reduce field welding, construction noise, and on-site waste.
- Efficient Installation: Clearly labeled components and bolted connections support organized assembly and can help shorten installation time.
- Adaptable Building Design: Structural layouts and building envelope options can be tailored to project requirements.
- Potential for Reuse: Steel components may be dismantled and reused where the connection design, component condition, and applicable regulations permit.
Our prefabrication process covers steel cutting, drilling, welding, end-plate fabrication, connection preparation, and surface treatment, as required by the project design. Dimensional inspections and fabrication checks can be carried out against approved drawings and specified tolerances.
Before shipment, components are identified and packed to support efficient handling, transportation, and installation at overseas project sites. English-language technical documentation, including installation instructions and relevant component information, can be provided according to the project scope.

- Office buildings
- Schools and educational facilities
- Apartment buildings
- Industrial buildings
- Modular public buildings
We supply clearly identified steel components with export packaging and English-language technical documentation. Component layouts, connection details, and installation instructions can be prepared in accordance with the approved project drawings.
Specifications and available configurations are confirmed during project engineering.

We provide prefabricated steel building components and structural solutions for international construction projects. Our business focuses on factory fabrication, component quality control, export preparation, and technical coordination for overseas installation.
Our product range includes prefabricated steel columns, beams, end plates, and structural connection components. Each project is coordinated according to its specified dimensions, structural requirements, and approved fabrication drawings.
By completing major fabrication operations before shipment, we help reduce on-site processing requirements and support a more organized construction process.
Dimensional inspection, connection-detail verification, surface protection checks, and component identification can be incorporated into the production process according to project specifications.
Clearly marked components and organized packing documentation help customers identify delivered materials and coordinate installation at the construction site.
We understand that international steel building projects require more than manufactured components. They also require clear documentation, coordinated packaging, and communication between suppliers, engineers, and installation teams.
Depending on the agreed supply scope, we can provide fabrication drawings, component lists, packing information, and English-language assembly instructions.
Our prefabricated steel structure systems can be configured for office buildings, schools, apartments, modular public buildings, and other applications. Wall and roof panels, doors, windows, and corrosion protection systems can be selected according to project needs.
We are committed to providing practical steel building solutions supported by clear specifications, coordinated production, and responsive project communication.
