New: Docol® Tube Option
Docol® tube is now available for select chassis builds and components. It delivers roughly 10–15% higher strength than 4130 with improved fatigue performance and a smaller, more tolerant heat-affected zone. With a clean mill finish and consistent properties, it typically requires less prep, resists warping/distortion, and welds up more predictably — ideal for high-stress chassis work.
Weld compatibility: TIG/MIG; welds to 4130 and mild steel.
