Metal Curving Unistrut Roll Forming Machines

Ametal curving unistrut roll forming machineis an industrial equipment used to continuously bend and form metal coil strips into customized channel beam profiles with curved shapes. Unistrut, also known as channel strut, is a hot-rolled, mill finish plain channel used in construction for its versatile structural support capabilities.

Roll forming utilizes a series of consecutive roller dies to gradually shape sheet metal coil into structural profiles with high dimensional accuracy and consistency at a rapid production rate. Metal curving unistrut roll forming machines allow manufacturers to create lightweight, high strength curved metal support channels on demand as per application requirements.

Metal Curving Unistrut Roll Forming MachineTypes

Machine Type	Description
C Profile	Forms standardized C-channel sections with radiused returns
U Profile	Forms industry standard U-channel sections with tighter radii
Custom Profile	Creates non-standard channel profiles as per custom design
Variable Section	Roll forms channels with varying widths and depths
Curved Profile	Imparts continuous curvature along the channel length

Working Principle Of Metal Curving Unistrut Roll Forming

The working principle involves unwinding metal coil strip, feeding into a series of roller dies to gradually bend the strip, finally cutting into desired lengths:

Coiled steel sheet is loaded onto adecoilerwhich straightens and feeds the strip through the infeed guides
The strip passes through a series ofroller dieseach with custom profile engraved. Dies shape the strip incrementally.
Pinch rollersgrip and transport the strip through the consecutive dies at a set speed
Profiled strip moves through thepost-cutting sectionwith specific punch and die to shear cut as per length
Formed channels with curved profile are moved out on the exit conveyor/rollers
Advanced machines allowonline drillingand other secondary processing

Frequently Asked Questions

Q: What sheet metal thickness can be roll formed into curved unistrut?

A: Standard machines handle metal thickness from 0.5 mm to 3 mm for curved channels. Heavy duty machines available for 5 mm thickness capacity.

Q: What is the ideal unistrut size for curved profile?

A: 50 mm x 30 mm, 80 mm x 40 mm, 100 mm x 50 mm are common rolled channel sizes for curved structural sections. Custom sizes possible.

Q: What degree of curvature can be achieved in roll formed channels?

A: Up to 120 degree continuous curvature along 10 m length is possible. Maximum bend radius ratio ~1 is standard for structural channels.

Q: How to design custom curved unistrut profile and tooling?

A: Share CAD models of desired profile shape with machine manufacturer. Their design team engineers suitable roller dies and tooling.

Q: What factors affect price of these roll forming machines?

A: Type of customized features, production speed, raw material width/gauge capacity, overall stiffening levels and length, secondary processing needs.

Q: How much area is needed to install a curved C channel roll former?

A: Approximately 36 feet x 10 feet for machine (feed to exit conveyors) plus decoiler, shear and space for formed products.
