Hollow Metal Xpress Joins SDI

December 19, 2013 PHOENIX, Arizona Hollow Metal Xpress (HMX) is the newest manufacturer to join the Steel Door Institute’s select membership. This brings SDI’s membership to 12 manufacturers.

The approval process included an onsite audit by steel door and frame engineers that certified HMX as meeting SDI’s rigorous standards. They had to meet other business criteria as well, such as selling products primarily through distributors in at least 15 states.

Based in Phoenix, AZ, HMX has roots in manufacturing hollow metal doors and frames manufacturing that go back 25 years. “We created our Project Services division in 2011 to compliment and add to the quick-ship services our company was founded upon,” said Steve Gay, Vice President and General Manager of HMX. “Joining an elite organization like SDI was the natural next step in our company’s development. We believe our SDI membership proves what we’ve been saying all along: HMX manufactures doors and frames that are consistent and of high quality.”
