Services
Welding and fabrication for heavy industrial work.
A Houston steel fabrication company for process piping, ASME pressure vessels, structural steel, specialty alloys, plate rolling, and full-service metal repair — shop and field.
Industrial fabrication services from one shop
Plants comparing welding and fabrication companies usually need more than a single process. Grazco, LLC takes heavy industrial fabrication that runs from spool pipe welding and ASME pressure vessel fabrication through structural steel, duplex and specialty alloys, plate rolling, and steel fabrication and metal repair.
Full-service welding, fabrication, and metal repair stays at 408 Northville St. Field crews cover Greater Houston, including the city pages for Houston, Barker, Katy, Crosby, Huffman, Conroe, Willis, Cleveland, and Rosenberg.
