Steel Building Features


How We’re Different

Panel Overlap

Mayflower Steel Buildings

Panel overlap

No caulking is required for waterproofing because the last 9″ of panel is smooth allowing the panels to fit snugly together. This makes assembly less difficult and saves you 30-40% on construction time.

Competition

Competition's panel overlap

The last 9″ of our competitor’s panels is crimped, preventing it from fitting snugly together. This makes it more difficult to assemble because more alignment with drift pins is required adding 30-40% more construction time. Caulking is also required for waterproofing taking up even more time because each overlap requires four rows of caulking to prevent leaks from occurring.

Panel Crimping

Mayflower Steel Buildings

Panel overlap

Crimps are closer together and smaller in depth preventing buckling problems. This adds 25% more strength.

Competition

Competition's panel overlap

Crimps are farther apart and larger in depth creating buckling problems and a weaker panel.

Hear What Our Customers Have to Say

“I needed a building because the old one had fallen down. It arrived and I had a 19-year old young lad help me and we erected it together. It was fun putting it up, it was very easy to follow the directions, if I ever needed another building I’d do the exact same. I’ve got my workbench in it, I’ve just unpacked all my stuff becuase of lack of space with the other building falling down and generally store all my tools, signs and equipment, whatever I have. I can now pull my mower in here. If I move everything I can pull my tractor in here if I want to work on it. I can just about do everything – it worked out great! Ijust love it. I can stay in here – live in here. If my wife kicks me out I might move in here.” – Nursery owner, Florida.
