"We hired Johnson Iron Works to erect a 253 kilowatt pre-engineered long-span solar carport. Jay Johnson was very easy to communicate and work with and quickly developed a plan to overcome fabrication issues that were identified after the materials arrived on site. Johnson Iron Works completed the job on time, and on budget. We were very happy with our decision to work with Johnson Ironworks and look forward to our next project with them."
