Flashing roll forming machines are an essential equipment for manufacturers of metal building components like roofing, siding, panels, studs and more. This guide provides a comprehensive overview of different types of flashing roll forming machines, their key features, applications, specifications, suppliers, installation, operation, maintenance and more.
Overview of Flashing Roll Forming Machines
Flashing roll forming machines are used to form trim or flashing components from coil stock of various metals like steel, aluminum, copper etc. Flashing provides weather sealing, prevents moisture ingress and thermally insulates metal roofing and wall systems.
Roll formed flashing components include drip edges, rake trims, corner trims, head trims, jamb trims, sill trims and more. Flashing roll formers process flat strip stock into angled, v-shaped or box shaped profiles continuously.
Key benefits of using flashing roll formers:
- High production speeds up to 120 ft/min
- Capability to form complex and heavy gauge flashing up to 0.125 in thick
- Superior quality and consistency versus other methods
- Reduced material waste
- Lower labor requirements
- Ability to integrate with other downstream equipment
Types of Flashing Roll Forming Machines
There are two main types of flashing roll formers:
| Standalone Roll Formers | In-line Roll Formers |
|---|---|
| Configured as complete roll forming lines withdecoilers, pre-cutting, notching, punching, rolling stations, post-cutting and exit tables | Designed to integrate into existing manufacturing lines by removing decoiling and exit end functions |
| Require dedicated operator and floor space | Compact and flexible for tight spaces |
| Higher capacities and production | Lower capacities but seamless integration |
| Well-suited for high volume dedicated flashing production | Better for mixed products or lower volume flashing |
Key Components of Flashing Roll Formers
Flashing roll forming machines have the following key components in sequence:
- Decoiler: Feeds raw coil stock into the roll former
- Feeder: Controls stock flow into the forming stations
- Pre-cutting: Cuts sheet length prior to forming
- Punching & Notching: Punches holes or notches if needed
- Forming stations: Progressively forms the flashing profile
- Post-cutting: Cuts formed profile to length
- Exit table: Stacks or transfers finished product
Modern roll formers may also include pinch rolls for pulling stock through each station, servomotor-based controls, and integration of punching, notching, or embossing units between stations.
Flashing Profiles and Geometries
Common flashing profiles and geometries formed by flashing roll formers:
- 90° angles: For drip edges, corner flashings
- V-shaped: For rake trims, ridge caps, roof transitions
- Box-shaped: For parapet flashings, head flashings
- Complex angles & bends: For door/window jambs, sills, curved components
- Embossed patterns: For decorative finishes
Advanced 3D modeling and tooling design allows flashing roll formers to produce almost any geometry.
