Heavy Fabrication – FAQ
A heavy metal fabricator manufactures large, high strength metal components and assemblies using processes such as cutting, forming, machining, and welding. Heavy fabrication is commonly used in construction projects, infrastructure builds, heavy machinery and mining equipment.
A heavy fabrication shop processes thick materials and manufactures welded assemblies designed for industrial applications. Typical projects include machine frames, equipment structures, equipment skids, supports, enclosures, and structural weldments.
Look at manufacturing capabilities, welding certifications, equipment capacity, production experience, and the number of processes performed in-house. Companies with integrated fabrication and welding operations often provide better quality control and shorter lead times
Yes, Seaborn manufactures both heavy sheet metal components and thick plate fabrications. This allows customers to source structural components, formed parts, enclosures, and welded assemblies from a single supplier.
Material thickness depends on material type and part geometry. Our equipment supports both sheet metal and heavy plate processing. We can laser cut up to 2” thick steel.
Engineering drawings and CAD models are preferred because they improve quotation accuracy and reduce project lead times. For quoting a properly toleranced PDF, or detailed dwg / dxf etc. are perfect.
