roof wall panel roll forming machine

Roof wall panel roll forming machines are essential equipment in the metal building and construction industry. This guide provides a detailed overview of roof wall panel roll forming machine technology, applications, specifications, selection criteria, and more.

Overview of Roof Wall Panel Roll Forming Machines

Roof wall panel roll forming machines, also known as roofing rollformers or roof panel rollformers, are designed to continuously bend and form metal coils into roof and wall panels used in metal building systems.

These machines transform flat metal stock into finished roofing or siding panels with shaped profiles by passing the material through a series of progressive roller dies. The rollers bend the metal incrementally as it moves through the machine to gradually form the desired panel shape and dimensions.

Roof wall panel roll forming provides an efficient, high-speed process to mass produce interlocking roofing and wall cladding panels in long lengths from thin gauge metal coils.

Roll formed roof and wall panels offer many benefits compared to traditional building materials:

  • Durable, lightweight, and corrosion resistant metal construction
  • Large panel sizes reduce seams and speed up installation
  • Insulated panels provide increased energy efficiency
  • Low maintenance and long service life
  • Fire resistance and storm resistance
  • Design flexibility and aesthetics

With precision roller dies, these machines can form roofing and siding panels in a wide variety of industry standard and custom profiles. Common panel styles include standing seam, batten, box rib, corrugated, and many more.

Roll formed panels are essential components of modern pre-engineered steel buildings, cold storage facilities, warehouses, aircraft hangars and commercial structures. They are also increasingly used in residential building construction.

Typical Components of a Roof Panel Roll Forming Line

A complete roofing panel production line includes several key pieces of equipment engineered to work together:

  • Uncoiler – Feeds metal coil stock into the roll former
  • Sheet guiding system – Keeps the coil sheet aligned and tensioned
  • Roll forming mill – Progressive dies shape the panel profile
  • Hydraulic system – Provides power and pressure to roll dies
  • Sheet cutting system – Cuts panels to length after forming

Many roll forming lines also integrate additional in-line processes:

  • Decoilers – Allow use of multiple coils for continuous production
  • Accumulators – Allow different line speeds between processes
  • Embossing stations – Add raised patterns to the panels
  • Cut-to-length saws – Precisely cut panels on demand
  • Hole punching – Punch slots for fasteners and interlocking edges
  • Stacking systems – Automatically stack cut panels

Advanced roof panel roll forming equipment can be quite complex, but the basic principle uses incremental roller dies to gradually reshape flat sheet metal into roofing profiles.

Typical Materials and Finishes for Roll Formed Roof Panels

Roll forming technology works with a wide selection of metals to produce roofing panels:

  • Galvanized steel
  • Galvalume coated steel
  • Aluminum
  • Copper
  • Zinc
  • Stainless steel
  • Titanium

These base metals are also available with different coatings and finishes:

  • Galvanized (zinc) coating – Corrosion protection
  • Aluminum-zinc alloy coating – Advanced corrosion resistance
  • Cool paint roof coatings – Solar reflective colors
  • Printed paint finishes – Custom color and patterns
  • Stone coatings – Granular mineral finishes
  • Weathering steel – Natural rust patina finish

Insulated metal roofing panels with foam or fiberglass cores are also manufactured on specialized lines equipped with fillers.

The most common metals used are galvanized, Galvalume, and pre-painted steel due to the optimum balance of strength, formability, corrosion resistance, and cost. Aluminum, stainless steel, and copper provide higher durability and aesthetic options.

Typical Specifications and Profiles of Roll Formed Roof Panels

Roll formed roof panels are produced in a vast selection of industry standard and proprietary profiles in different sizes, thicknesses, and strengths.

Some of the most common panel profiles and dimensions include:

Standing Seam

  • Widths: 12″, 16″, 18″
  • Rib height: 1.5″, 2″
  • Metal thickness: 24ga to 22ga

Corrugated Panel

  • Corrugation size: 2.67″x0.5″ or 5″x1″
  • Widths: 26″, 29″, 36″
  • Metal thickness: 24ga to 29ga

Box Rib Panel

  • Rib height: 1″, 1.5″, 2″
  • Rib spacing: 6″, 8″, 12″
  • Widths: 26″, 29″, 32″, 36″

  • Spacing: 8″,12″, 16″, 24″
  • Widths: 24″, 26″, 29″, 36″
  • Metal thickness: 24ga to 29ga

Custom or specialized roofing profiles are also possible. Common options include:

  • Vee-Rib, U-Rib, Trapezoidal Rib
  • Shadow lines, beads, flutes
  • Striated, diamond plate, embossed textures
  • Flat pan, plank, diamond decking
  • Shingles, shakes, tile looks

Roll formed metal panels can replicate almost any roofing profile imaginable with the right roller dies. Complex geometries may require a larger roller pass sequence and more forming stages.

The metal thickness used ranges from 0.014″ (24ga) to 0.040 (22ga) for steel and 0.032″ (20ga) to 0.125″ (1/8″) for aluminum. Copper panels can be produced from 16oz to 20oz thick stock.

Heavier gauge metals provide greater rigidity and span capability but are harder to form without stretching or cracking. Thinner gauge metals offer flexibility and easier forming but may not be suitable for all roof load conditions.

Roll Forming Production Capacity

Production capacity of a roof panel roll forming line depends on:

  • Line speed
  • Operating hours per shift
  • Number of shifts per day

Higher speeds, extended hours, and added shifts can greatly increase output.

Typical line speed range:

  • Steel panels – 40 to 200 ft/min
  • Aluminum panels – 80 to 300 ft/min

Output capacity range:

  • 20,000 to 40,000 SF per 8 hour shift

On a single shift basis with average line speeds, a typical production rate is:

  • 1,000 to 1,500 square feet per hour
  • 8,000 to 12,000 square feet per 8 hour shift

So a single roll former can produce from 100,000 to over 1 million square feet per month if run 24/7.

Adding multiple roll forming lines can increase capacity to meet higher volume demand.
