Used Bradbury Metal Stud Roll Forming Line | Galaxie Corporation, Wayne, Michigan, USA

This used Bradbury metal stud roll forming line is available from Galaxie Corporation. It forms galvanised steel studs and track in 3.625″ and 6″ sizes, with pre-punching and pre-cutting handled by two hydraulic presses ahead of the rollformer.

The line takes G60 galvanised steel from 0.021″ to 0.060″ thick, in coils up to 6,500 lbs. The rollformer is geared for up to 150 FPM, and finished-product throughput reaches 120 FPM at cut lengths of 8′–20′.

Key Features
