Installations to Existing Structures

Hatch Installations

our structural welders installed three hatches into water purifying tanks at a water treatment facility in the Des Moines, Iowa area.

Temporary Mezzanine

a cement company needed a large piece of equipment transferred from an upper level of a building down to the ground for transport. Our structural welding team crafted a platform 80 feet in the air that would then maneuver the damper over the side of the building.

Staircase Installations

with OSHA’s new rule surrounding fall protection standards for fixed ladders, many facilities have been opting to install staircases in lieu of using ladders and harnesses

Emergency Repairs

When it comes to welding, accuracy and precision are key and here at McMahan we take pride in our high-quality, structural welding services. Whether you’re adding on to an existing structure, or you’re looking for a quick fix for a work hazard, we are ready to help.

Over the years we have worked on different structural projects around the greater Des Moines area and Ames, and have even travelled as far as Sioux Falls, South Dakota and Omaha, Nebraska. Some of these projects include adding a handrail to the top of a water tower, reinforcing damaged steel columns, and adding a staircase to a cat-walk system.
