Overview
Drywall roll forming machines are used to continuously bend and form metal or steel coils into customized drywall studs and track profiles. They offer an efficient automated solution for high volume drywall framing production.
Key details about drywall roll forming machines:
- Also called stud and track roll formers
- Form C-studs, U-channels, top and bottom tracks from coil strips
- Range from basic 5-10 station to high speed 50 station machines
- Roll widths up to 2.5 m, thicknesses up to 3 mm
- Speeds from 10-100 m/min
- Provide profiles as per design specifications
- Reduces labor and improves flexibility compared to traditional framing
Drywall Framing System Overview
Drywall construction uses a framing system of metal vertical studs and horizontal tracks to create the interior wall framework. Drywall panels are then attached to the framing to build partitions.
- Framing provides the structural support for drywall walls and ceilings
- Made of galvanized steel for strength, fire safety, mold resistance
- Channels and studs interlock through bent tabs to assemble framework
- Sizes determined by building codes and load requirements
- Spacing of studs is typically 16 or 24 inches on center
Key framing components produced by roll forming:
- C-studs – C shaped vertical studs used to frame interior walls
- Top and bottom tracks – U shaped channels that attach to floor and ceiling
- Header tracks – Reinforced channels over openings like doors
- Furring channels – Hat shaped strips used on ceilings
