Topper aluminum truss design catwalks will give your employees a feeling of security as they walk from one end to the other. It is typical to include a mid rail and toe rail for OSHA safety regulations on all catwalks, and a deck material such as Grip Strut or Perf-O-Grip. It is common to link a number of catwalks in succession to reach out hundreds of feet. Give us the pile locations and we’ll take care of the rest.
