Fabrication refers to the process of manufacturing the steel components that will later be assembled into the structure. The key steps involved typically include:
Design & Engineering : The first step is creating detailed structural and architectural designs, often customized to the client’s specifications. These designs help define the size, shape, and structural needs of the building.
Material Selection: High-quality steel and other materials are selected based on factors like strength, durability, and environmental conditions. Steel is the primary material used for PEBs due to its flexibility and strength-to-weight ratio.
Cutting and Shaping: The steel components, like beams, columns, purlins, and roof panels, are cut, shaped, and fabricated in a factory setting. CNC machines, plasma cutters, and other advanced technology may be used to ensure precision.
Welding and Assembly: The fabricated parts are welded together or bolted to form larger components, such as frames or trusses. This is often done using automated machines, although manual labor may also be required.
Pre-assembly: Before shipping to the construction site, some PEB components may undergo a pre-assembly phase to check for fit and function, ensuring that everything aligns correctly for the final build.
Quality Control: Throughout the fabrication process, strict quality control measures are followed to ensure that all parts meet industry standards and are free from defects.
Transport to Site: Once the fabrication is complete, the parts are packaged and transported to the construction site, where they are ready to be assembled into the final structure.
The benefit of PEBs is that the materials are often mass-produced and pre-engineered in a way that reduces on-site construction time, allowing for faster project completion.
