Areas we serveHouston, TexasHarris County
Grazco, LLC is a pipe and steel fabrication company in Houston, not a desk that subcontracts the weld. The shop does precision welding and fabrication for Houston plants: process spools, structural steel, pressure vessels, and the field tie-in, from the same company. Fabrication companies in Houston often split shop and field. This one does not.
The address is 408 Northville St, Houston, TX 77037, in north Houston. Crews drive south to the Ship Channel, west toward the Energy Corridor, and out to the suburbs listed on this site. Refinery, chemical-plant, and oil-and-gas work is the usual call. A small shop repair is the same phone line.
Work we take in Houston
Pressure vessels and high-pressure pipe
Houston vessel work is quoted here first: shells, nozzles, weld repair, and the high-pressure pipe that ties in. Send the code and the inspector with the drawings.
Process piping and spools
Cooling-tower, chill-water, and process spools are fabricated on Northville Street and installed by the field crew, including B31.3 and B31.8 work when that is the spec.
Shop and field welding
TIG, GMAW, and sub-arc, with X-ray when the specification requires it. Pipe welding near the shop is a short haul. Contract welding goes to the plant.
Structural steel fabricators, stainless, and specialty alloys are on the services list. Start with ASME pressure vessel fabrication, process piping and spool fabrication, and certified X-ray TIG, GMAW, and sub-arc welding if you are sorting a bid.
Suburb pages cover the cities that show up most often with this shop: Barker, Katy, Crosby, Huffman, Conroe, Willis, Cleveland, and Rosenberg. Other Houston-area cities are listed on areas we serve without their own pages.
