Standard PEB designs cannot accommodate the complex geometric and load requirements of modern, multi-tier industrial processing plants. The project illustrated above demonstrates our capability to execute highly customized steel structures. By utilizing advanced Building Information Modeling (BIM), we resolve spatial conflicts between structural steel, heavy overhead cranes, and mechanical routing before fabrication begins.
While standard H-beams are sufficient for many projects, this facility utilizes heavy-duty steel pipes—Circular Hollow Sections (CHS)—for its primary columns. CHS profiles provide superior compressive strength and equal multi-directional bending resistance, making them highly efficient for tall structures subjected to complex wind or seismic shear forces.
