Structural beam fabrication is the process of designing, manufacturing, and assembling steel or other metal beams that are used in construction and engineering projects. These beams are designed to provide support and stability to the structure above, and to withstand various stresses such as weight, bending and twisting.

The process starts with the design of the beam, which takes into account the specific load and performance requirements of the project. The design considers factors such as the type of structure, the weight it will bear, wind loads and more. The steel or other metal used for the beam is cut to the correct length, bent, and shaped according to the design specifications. After the beam is manufactured, it goes through a quality control process to ensure that it meets the required standards and specifications.

Finally, the beam is assembled and welded together to form the final product. This process is usually done on-site, where the beam is lifted into place and fixed to the structure.
