Why The Iron Institute

Built From
the Inside Out

01
Domain expertise, not software guessing
Every piece of content comes from years of working in steel pipe distribution. If it's in here, it's been verified against the actual standard.
02
The nuance that changes the answer
A53 can be seamless — most people don't know that. P91 Type 1 and Type 2 share the same UNS number. India is not TAA compliant despite producing fully ASTM-certified pipe.
03
Mobile-first, field-ready
Designed for the person standing next to a pipe rack, not the engineer at a second monitor. Fast, readable, works on the phone you have with you.
04
Grows with the industry
Bar, beam, fittings, flanges — the same tool suite expanding across every form of steel. One place built for everyone from buyer to engineer to field hand.

"The field engineer shouldn't have to open four tabs, a PDF, and a spreadsheet to figure out if 6-inch SCH 40 A106 Grade B meets the pressure requirement.

That answer should take ten seconds."
