Floor & Roof Trusses

Trusses are what we build. Every one is engineered, cut, and inspected in our Chicago shop before it leaves the yard, for residential, commercial, and industrial projects across Illinois, Indiana, Wisconsin, and Michigan.

Floor Trusses

Floor trusses are engineered structural components used to support flooring systems with exceptional strength and stability. They use a grid-like design of interconnected triangular web members, which lets them span long distances and open up larger rooms without additional supports underneath.

Those open webs are also what make them practical to build with: ductwork, plumbing, and electrical run straight through the floor system instead of forcing you to drill joists or drop a ceiling. Light, cost-effective, and suited to residential, commercial, and industrial projects alike.

Roof Trusses

Roof trusses span long distances too, giving you open and versatile interior spaces. They are precision-engineered to meet the specific load requirements of the building and can be shaped to suit the architecture: regular, scissor, gambrel, cathedral, attic, monopitch, and more.

Strength, cost-effectiveness, and design flexibility are why they are the common choice for residential, commercial, and industrial roofs.

What we build

  • Trusses from 12″ to 24″ deep
  • Flat roofs with sloped trusses, from regular up to 100 lb loads
  • Scissor trusses and regular common roof trusses from 20′ to 46′ wide
