Panel Curving

The first U.S. manufacturer to curve symmetrically designed structural panels, IMETCO is able to achieve the tightest curves in the industry and curve longer panels than most.

IMETCO offers several curving options, including a standard convex curve, a concave “reverse” curve, and a continuous and smooth concave-to-convex “S” curve.

These extraordinary S-shaped panels are truly a sight to behold as your eye travels along the reverse-curve radius and continues seamlessly along the tangent to the standard convex curve. These unique capabilities gives designers even more creative options to achieve this dynamic aesthetic.


Curving Long Panels? IMETCO’s Field Curving Capabilities Are Second to None

IMETCO’s field formed and field curved panels offer the same warranted, proven performance as those manufactured in our plant. This video shows field forming and field S-curving of Series 300 metal roofing panels on the Slidell Municipal Auditorium in Slidell, LA.

Panel Tapering

Our quality control does not begin in the factory, but rather with the dedicated engineering team that works closely with the designer and contractor on each and every project to eliminate installation challenges, reduce waste, and ensure that IMETCO’s tapered panels provide the stunning visual impact desired. Our dedicated manufacturing, engineering, and project management teams work closely with designers and contractors to address installation challenges, reduce waste, and maintain performance characteristics of the roofing system.

IMETCO panels are custom-tapered to ensure a perfect fit. Tapered panels, which can exceed 80 feet in length, are factory formed from a single piece of metal – not pieced together from joined metal. They are manufactured with stiffening beads adjacent to the vertical panel legs only, preserving the flat, clean look of the panel’s center.

Field Rolling & Curving

From our factory-quality forming equipment to our onsite fabrication experts, IMETCO’s field formed panels offer the same warranted, proven performance as those manufactured in our plant.

IMETCO’s field roll equipment is full-service factory-quality featuring 16 roll stations and tension leveling – it is not a scaled-down secondary or “portable” model. It is shipped with a de-coiler to your job site on a 45-foot trailer, then set up and operated on-site by the same talented metal craftsmen who manufacture IMETCO’s high-performance metal systems in our factory.

Spreader Bar

Long panels are often desirable, since end-laps are eliminated and visual continuity is maintained. IMETCO’s ability to form and ship panels up to 85 feet in length, and to field form longer panels, opens a world of possibilities.

However, once long panels are fabricated, whether in the factory or on the job site, the installer is still faced with getting them up on the roof. Lifting long and/or curved panels can dramatically increase the risk of injury or property damage if the proper equipment is not used, particularly when the installer uses lifting devices that are field-fabricated or “home-made.”

Improper lifting can also increase the likelihood of oil canning, weaken the structural integrity of the panels, and result in panel damage ranging from minor dings to total destruction of the panel.

IMETCO recommends using its Engineered Spreader Bar to lift long and curved metal roofing panels. Using this unique apparatus will help installers:

  • Limit liability
  • Reduce risk of injury or property damage
  • Protect the design and condition of panels
  • Maintain engineered quality of roofing panels
  • Expedite delivery of materials to elevated location
  • Increase productivity, which can reduce labor and crane rental costs

IMETCO’s Spreader Bar is composed of five individual 40-foot sections, which can be combined as needed to lift panels up to 220-ft in length.

IMETCO supplies a complete spreader bar assembly, which includes upper and lower rigging, tag lines, assembly tools and detailed instructions with photos and illustrations. The unique upper and lower rigging equipment supplied with every rental makes preparing panels for lifting remarkably fast and easy. It is easily adjustable to accommodate multiple rigging requirements on the same project, and very quick and simple to set up.

IMETCO’s Field Services department is available to consult with you on project site staging, and in collaboration with a national crane company, can also help you determine crane requirements and sizing for your specific project site.


Roof-mounted solar systems make the best use of available space, turning unused space into an energy-producing asset. Standing seam metal systems have been deemed by architects and solar designers as the ideal material for rooftop photovoltaic (PV) installations. In addition to its performance characteristics and long lifespan, standing seam roofing provides a more complimentary aesthetic to PV systems than other roofing materials.

Whether designing for solar power today, or keeping options open for tomorrow’s possibilities, IMETCO’s standing seam metal roofing products allow designers to plan for the future with profiles that will accept PV systems now or later.

PV is not only for new buildings. When an existing building needs a new roof, why not take the opportunity to install (or plan for) a PV system as well? Since standing seam metal roofs can be installed over virtually any type of roof, what once was a costly maintenance project can now become an energy-generating mission.

Two Types of Rooftop PV Technology: Crystalline and Thin-film

Polycrystalline modules offer higher annual energy production due to minimal temperature dependence and excellent low light response. Racks of these modules can be clamped securely to the seams of a metal roof without creating penetrations. While installers can use hat channels to mount racks on metal, a rated clamp designed for that specific metal profile helps prevent liability issues that can arise on large projects. With an engineered product, such as S5! clamps available from IMETCO, PV racks can meet the required wind uplift and load ratings without penetrating the roof.

Thin-film amorphous silicon technology panels feature a flexible membrane created from layers of silicon on a thin sheet of stainless steel. While this type of system is less efficient than crystal modules (and requires a greater coverage area to produce the same wattage), it is less expensive to manufacture. These thin film modules can be adhered to the pan of a Series 300 standing seam metal roofing panel and wired through the ridge cap with no penetrations for mounting or wiring. Grid pairing is also possible with thin film modules.

Perforated Panels

Perforated screen walls are available in Latitude, Cor-Pan and R-Panel systems in steel, aluminum and zinc.

Shop Drawing & Submittal Packages

A thoroughly engineered shop drawing package is crucial to the success of every project. In addition to the standard details that are available for download, IMETCO offers shop drawings that are produced in-house by IMETCO engineers and customized to the unique requirements of your project. This helps simplify and expedite resolution of any design challenge you may face during project planning and installation. These comprehensive, engineered packages help ensure optimum product performance, proper installation, and code compliance, thereby reducing potential liability for design professionals, installers, and building owners.

Shop drawing packages address myriad design and liability considerations, such as:

  • Wind uplift requirements
  • Water control, drainage and run-off
  • Ice damming
  • Snow retention
  • Watertight detaill
  • Thermal movement allowances
  • Aesthetic considerations
  • Proper product installation
  • Coordinating transitional conditions and adjacent building materials
  • Building code compliance
  • Optional P.E. stamping (available for any state)

For the Installer: Supporting Installation Guidelines and Drawings

Roofing contractors face many challenges on the job site. IMETCO’s shop drawing packages included detailed, illustrated step-by-step installation guidelines to help you with installation challenges such as:

  • Varied experience
  • Varied installation techniques
  • Language barriers
  • Training of new crew members
