Ceiling T grid roll forming machines are used to produce T grid profiles for suspended ceiling systems. They form metal coil into the characteristic T shape through a series of progressive roll forming stations. Ceiling grids provide an exposed structure to support ceiling tiles or panels in commercial and residential buildings.
This comprehensive guide will cover all aspects of ceiling T grid roll forming machines including:
Overview of Ceiling T Grid Roll Forming Machine
A ceiling T grid roll forming machine takes flat metal coil as input and processes it through a series of roller dies to continuously form the strip into the final T shaped profile. The formed T grids are used as support systems for modular dropped ceilings.
The grid layout creates a frame to support ceiling tiles and provides access to the plenum space above the ceiling for electrical, plumbing and HVAC systems. T grid profiles provide an exposed and aesthetically pleasing ceiling with easy access to the space above.
Main Components
- Uncoiler
- Feeder
- Roll forming stations
- Hydraulic system
- Cutoff device
- Finishing stations
Working Principle
The uncoiler holds the coil of flat sheet metal that is fed into the roll former. The feeder has punching and notching units to create holes or slots in the strip before forming. In the roll forming section, the strip goes through a series of progressive dies and bending rolls that gradually shape it into the T profile with the web and flange. Hydraulic cylinders precisely control the rolls for accurate forming. After rolling, the cutoff device shears the formed grid to the desired length. Additional operations like punching, notching, branding and hardware insertion can then be done at finishing stations.
