  • 5 star review  I have been working with Roman Grigoriev to erect a 25 x 30 Steel Alpine building. He has been very helpful in answering my questions, as I have never done this before and needed some guidance as to what steps to take to get the building up. He has been excellent at keeping my costs down and getting me the right accessories! So far, I've been very impressed and look forward to keep learning the process. He has been helping me along the way and has "simplified" the process helping me to feel more comfortable getting to the final stage. Thanks!

    5 star review  Just a short note to say ... thanks. Roman has been very helpful with my pursuit of a structure that is suitable to my needs. At this writing, I am still in my decision-making process. This said, Roman continues his assistance providing information and solid advice. I look forward to continuing my inter-actions with Roman. Cheers.

  • 5 star review  Roman thanks for your professionalism offering us a quote for steel building. The quote was very professional and Roman customer services was perfect. Unfortunately, our company decided for a different concept of construction but I am really satisfied with the Metal Pro Building sales service.

    5 star review  We are in the process of erecting our 40 x 50 steel rigid frame building we purchased from Oliver at Metal Pro Buildings. So far the experience has been flawless. We received exactly the building we ordered and any question we had was always answered by Oliver. He made certain contractual commitments to us that he lived up to. We are very happy with our building and particularly the service we have received. We would definitely buy another building through Oliver and Metal Pro in the future...
