"I would highly recommend Factory Steel Overstock. Their core philosophy may be a departure from most companies but this should be encouraging rather than off putting. All of our interactions from inception and planning to receipt of the building were flawless and handled in a professional and courteous manner.  We estimate a savings of over 30% V's dealing with a more traditional company."  - C.H. on 3/7/16 posted on BBB website

Thank you Factory Steel and John and his team for a job well done. One of my fears was buying a steel building and having to ship it outside the country, and wondered what would happen if something goes wrong. You walked me through the process and gave me sound advice as this was new to me. You have made my building process so easy. You responded to every email and phone call. Thank You So Must and I’m recommend you to every in the Bahamas.   PS  3/27/2018
