  • Kept our project on schedule

    We needed a quick turnaround on B Decking for the canopy over the main entrance at Grand Design’s new Customer Support Center… [Structural Deck] was able to deliver the material within 2 days of my order and kept our project on schedule.

  • Great product at a great price

    We chose to use [Structural Deck] for B-decking because the level of service… is always second to none. Great product at a great price point. Highly recommend.

  • They over exceeds every deck supplier in the business!

    R.W. Welding Inc. has been in business for 23 and we have purchased metal decking from other suppliers over the years and recently have purchased some galvanized b decking from StructuralDeck.com and I got to tell you WOW!!! What a difference! They over exceeds every deck supplier in the business! I would highly recommend them for your metal decking supplier!
