Manufacturing Process of Steel Structure Factory Buildings

1.Design and Engineering
Structural engineers create detailed drawings and 3D models based on project requirements.
Load calculations, material selection, and connection details are determined to ensure safety and durability.
2.Material Preparation
High-quality steel is procured and inspected.
Steel plates, beams, and columns are cut, drilled, and shaped according to design specifications.
3.Fabrication
Steel components are welded, bolted, or riveted together in the factory.
Surface treatment, such as sandblasting and primer coating, is applied to prevent corrosion.
4.Quality Control
Each component undergoes strict inspection for dimensions, welding quality, and surface finish.
Non-destructive testing (NDT) may be performed for critical parts.
