Red Iron.
Heavy-frame steel for the largest spans and tallest builds
The Numbers
Largest Commercial — Hangars, warehouses, arenas.
Pick red iron when the building has to go big — spans beyond 80 feet, eaves over 30 feet, or roof loads that need to carry cranes, gantries, or racking. Hangars, arenas, and large commercial warehouses live here. Longer lead time and more equipment on site, but nothing else matches it for clear span and height.
Engineered I-beam columns and rafters fabricated to project specific engineered requirements, shipped to site, and bolted together as a portal frame. Sheeted with metal panels, hot-rolled steel will stand the test of time. Although it has the longest lead-time and requires the most equipment, nothing does bigger better than Red-Iron.
Testimonials
“Nate and his experienced crew did a fantastic job erecting our 35' x 40' steel shop. I found NatMar through an internet search. I selected NatMar because they were local, displayed excellent expertise, and were competitively priced. Their communications and administration were flawless. The crew was always punctual, polite, and worked with care and attention to detail. We had some challenges along the way; however, everything was dealt with without any fuss or penny-pinching.”
“Nathan and his crew are top notch! They were able to fit in my small project between their bigger jobs which got me finished real quick. They do great quality work and I would highly recommend NatMar to anyone.”
“Complete project was good quality, on time, on budget and craftsmen were very professional. If I could find anything not perfect would be the screws scattered around post completion which is petty. Great job guys!”
“Nathan Margosian of NatMar Construction and his crew have been nothing but excellent. They have just completed a third building for me in the last year. Nathans customer service, punctuality at completion on time, and completing on budget is unmatched, all at a very fair and reasonable rate.
