Structural Steel

Posts, beams, columns and steel framing, fit and welded right where the steel stands, and repaired when a connection cracks or a post base rusts through. We weld for the property owner or for the contractor running the job, and the rig brings its own power.

Posts, beams and columns

Steel posts, beams and columns get cut, fit and welded in place, with base plates, cap plates and connection plates made to match what's already there. Every joint is ground to clean metal before the first bead goes in, because a structural weld starts with good fit-up.

Steel frames and balconies

A backyard balcony in downtown Sonora is a good example. The steel frame was fit up and welded on site in 3/8 inch channel, start to finish in a single day, with the owner kept in the loop from the first cut to the last weld. Real-world material conditions come with any job like this, so weld prep gets the time it needs.

Structural repairs

Steel that's cracked, rusted or bent gets cut back to sound metal, rewelded and reinforced with new plate where it helps. Much of this work happens on existing barns, shops and outbuildings, with the structure still standing.

  • Steel posts, columns and base plates
  • Beams, channel and tube steel
  • Balcony and deck support frames
  • Cracked welds and broken connections
  • Rusted post bottoms cut out and replaced
  • Barn and shop frame repairs
  • Purlins, girts and cross bracing
  • Gussets, clips and reinforcing plate

Up on the lift, for you or your contractor

Structural welding often means working overhead from a lift or a ladder, and the rig carries its own welder, torch and plasma cutter, so there's no need for power at the site. Plate and heavy sections in the 3/4 to 1 inch range are regular work. Whether you own the property or you're the contractor running the job, we show up ready to weld to your plans and your schedule.
