Standing Seam Metal Roll Forming Machines

Standing seam metal roll forming machines are an essential equipment for manufacturers of metal roofing and siding panels. This comprehensive guide provides an overview of standing seam roll formers, their working, types, applications, specifications, suppliers, installation, operation, maintenance, and benefits.

Overview of Standing Seam Metal Roll Forming Machines

Standing seam metal roll forming machines create corrugated or interlocking raised seams on metal panels. The seams enable joining of panels and provide mechanical strength. Roll forming converts flat metal coils into shaped panel profiles by progressively bending the strip through consecutive roller dies.

What is a Standing Seam Metal Roof?

A standing seam metal roof has raised seams where panel edges fold over each other. The vertical seams interlock panels together from eave to ridge. This allows panels to expand and contract freely with temperature changes. Panels are attached to the structure without penetration of the metal surface.

Advantages of Standing Seam Metal Roofs

  • Durability – Lasts 50 years or more with minimal maintenance
  • Wind and fire resistance – Seams allow flexibility during high winds
  • Leak resistance – Water runs off with no penetration points
  • Energy efficiency – Reflective surface and thermal break under seams
  • Aesthetics – Available in variety of colors with attractive seams

Roll forming is a continuous bending process which converts a flat strip of sheet metal into a desired cross-sectional shape by passing it through consecutive roller dies. Each die makes a small incremental bend until the final profile is achieved. Standard components of a roll former include:

  • Coil feed unit
  • Feed table with pinch rolls
  • Roller station unit with roller dies
  • Cutoff press
  • Output table

The sheet is pulled from the coil through the rollers by drive rolls. Roller stations make the longitudinal bends while transverse dies make ribbing or embossing. Cutoff dies shear the panels to required length.

How Standing Seam Roll Forming Works

The roll forming process shapes metal coils into panels with raised seams in a continuous process:

  1. Coil strip pretreated for corrosion resistance is loaded on the powered de-coiler which feeds the strip through an initial leveling stage.
  2. The strip enters the forming section and passes through consecutive roller stations. Each set of rollers makes a incremental bend until the complete panel profile is achieved.
  3. Seam rollers fold over the edges longitudinally to form interlocking standing seams. Transverse dies can make ribs for added rigidity.
  4. After forming, the cutoff press shears the strip to required panel length based on preset parameters.
  5. Conveyors transport finished panels to the exit for inspection and downstream processes like coating, accessories or palletizing.
  6. Roller stations are equipped with quick change tooling to allow fast die changeovers for different seam configurations.
  7. Automatic controls synchronize the roller stations and cutoff operation for continuous high-speed production.
