The environmental math is real. Melting recycled scrap in an EAF uses about 75% less energy than smelting virgin iron ore in a traditional blast furnace. CO\u2082 emissions drop by 58\u201370% per ton. And at end of life, every steel stud is 100% recyclable \u2014 it goes right back into the furnace and becomes another building. Not downcycled. Not landfilled. Recycled into the same product, indefinitely.<\/p>\n
The U.S. already sits on a scrap reservoir of over 4 billion tons and growing. That’s not a supply-chain vulnerability \u2014 it’s a domestic advantage. Especially in a year when tariffs have pushed imported steel prices up over 20%, the fact that most CFS comes from domestically melted scrap isn’t just a sustainability story. It’s a pricing and supply story too.<\/p>\n
What this means for your next project<\/strong><\/p>\n If you’re a developer weighing steel framing against wood or concrete, the carbon conversation has shifted. Cold-formed steel framing carries some of the lowest embodied carbon of any structural material \u2014 not because of a marketing claim, but because of what it’s actually made from.<\/p>\n If you’re a factory owner or fabricator, the material you run through your roll-former was never mined. It was recycled.<\/p>\n And if you’ve never thought about where a steel stud comes from before reading this, now you know. It was probably someone’s car.<\/p>\n FAQ<\/strong><\/p>\n What is cold-formed steel made from? <\/strong>Cold-formed steel is made primarily from recycled scrap metal \u2014 old vehicles, appliances, demolished buildings, and manufacturing offcuts \u2014 melted in electric arc furnaces and reformed into sheet steel. EAF steelmaking uses 80\u2013100% recycled scrap as its raw material input.<\/p>\n Is cold-formed steel framing sustainable? <\/strong>Yes. CFS is one of the most sustainable structural framing materials available. It is made from recycled scrap, produced in electric arc furnaces that use 75% less energy and emit 58\u201370% less CO\u2082 than traditional blast furnaces, and is 100% recyclable at end of life without any loss in quality.<\/p>\n How much U.S. steel comes from recycled scrap? <\/strong>Approximately 70% of all U.S. steel is now produced in electric arc furnaces using recycled scrap, and that figure is projected to reach 90% by 2040.<\/p>\n Can steel be recycled indefinitely? <\/strong>Yes. Steel can be melted and reformed without degrading its structural properties. A steel stud removed from a demolished building can be recycled into a new stud for a new building. This makes steel one of the few truly circular construction materials.<\/p>\n The wall panels in your building most probably started life as scrapped vehicles, old appliances, and demolished structures. Here’s how.
