Natural Metal Panel Systems

Enhance your project with the timeless beauty and lustre of natural metals such as aluminum, zinc, copper or stainless steel.
Available in numerous finishes, these materials have the capability to evolve and add unique character to building facades over time.


Single-Skin Modular Panel System

SurFlex™ is a pressure equalized, single-skin modular panel system that has been tested to the American Architectural Manufacturers Association (AAMA) 508 standard for Pressure Equalized Rainscreen (PER) systems.  This dry joint system uses formed panels with  interlocking joints.  SurFlex™ does not require clips or extrusions and can be easily installed directly onto building substrates.  Manufactured using an automated production process, SurFlex™ is one of the most economical and cost-effective panel systems on the market.

For either a subtle or dramatic effect, SurFlex™ has numerous design and pattern possibilities that assist in showcasing a very modern and contemporary look to exterior facades. As shown below, these include: Standard, Perforated, 3-Dimensional or Tapered options

SurFlex™ is a dry joint system designed, engineered and manufactured by Sobotec. Modular panels create a pressured equalized rainscreen system that does not require clips or extrusions. SurFlex™ eliminates exposed rivets and fasteners at the panel perimeter, providing a crisp, clean appearance. SurFlex™ has been proven and tested to the following specified performance requirements:


  • ASTM E1233:     Cyclic Static Air Pressure
  • ASTM E330:       Structural Performance
  • ASTM E28:         Air Infiltration
  • ASTM E331:       Water Penetration
  • AAMA 508:         Pressure-Equalized Rainscreen System


Sobotec’s SurFlex™ panel system is adaptable to different project conditions. Our system design allows for modifications without sacrificing performance. The system integrates with flashings, closures and trims manufactured by Sobotec. Selecting a single source provider like Sobotec allows for efficient integration of these key building elements creating a rainscreen system which meets the highest design and performance requirements.


All SurFlex™ panel systems are made in North America, using recycled material. Applicable for LEED credits, SurFlex™ provides a high degree of sustainability as the panel system can be reused or recycled at the end of the product's lifecycle. Manufactured using a lean process, SurFlex™ can assist projects to achieve zero-waste when the designs are optimized.  This allows projects to reduce their overall environmental impact and carbon footprint.

Dry Joint Pressure Equalized Rainscreen (PER) System

The SL-2000P system is another low-maintenance PER system with numerous design and fabrication options.  Similar to the SL-1000P, this system incorporates solid metal materials at the panel joints. The wall attachment, air/vapour barrier seals and joint treatment are to the Sobotec SL-2000 standards, yet uses solid aluminum plate material.  The joint filler for this system can also vary in both color and joint size.  This systems meets the same testing criteria of the American Architectural Manufacturers Association (AAMA) 508 standard for PER systems.  The SL-2000P system can also be used with natural metals such as zinc, copper and stainless steel. Yet aluminum plate is most often used when requiring a painted surface.

Special Features

  • Pressure Equalized Rainscreen System
  • Ventilated cavity allows wall to breathe
  • Joint filler allows for variable color and reveal size
  • Low-maintenance, flexible panel design
  • Concealed air barrier membrane provides improved weather resistance
