Kind words from our customers:

  • “I have enjoyed working with GWY. Their people know their product well. Their prompt response and delivery of the product is as good as any service Ogeechee Steel has ever had the pleasure of doing business with.”

  • “GWY has been a great company to work with. My company requires receipts for all credit card purchases and GWY has made this very easy. With rental equipment this usually isn't the easiest to deal with but they have made this process very smooth. I get a weekly receipt emailed to me without having to ask for it. They also have great customer service and are very helpful and friendly. Would definitely recommend.”
