Metal Construction News highlighted a major advancement in steel fabrication technology — and The Purlin Mill was at the center of it. By installing the first 40-foot Jorns JDB Double Bending Machine in North America, The Purlin Mill became the only U.S. manufacturer capable of delivering bent metal products at this scale and precision.
What Makes the Jorns Double Bender Unique?
The Jorns Double Bender (JDB) has been providing architectural advantages worldwide for more than 20 years, but The Purlin Mill’s 40-foot model represents a new era of capability in the U.S. market.
Key Capabilities Include:
- 49” maximum throat depth for deep, complex profiles
- 40’ maximum bending length for large-scale parts
- Material range: 30-gauge to 11-gauge steel, 4.0 mm aluminum, and 2.0 mm stainless steel
- Clean, accurate bends that eliminate waste and rework
Unlike conventional folding machines, the Jorns Double Bender produces:
