High Static Load Capacity Roof Panel

BRUCHAPaneel® Roof DP

From a construction perspective, BRUCHA Roof Panel DP is a warm roof solution with steel sheet outer shells, polyiso insulation core thicknesses between 1-6″, and very high load-bearing capacity ideal for saddle and single pitched roofs. The trapezoidal shape of the upper rib elements provides excellent stability and can easily be adjusted, regardless of the sub-structure, to meet static requirements (roof pitches of 3° and up possible).

The BRUCHA Roof Panel DP can be quickly and easily installed in a single operation, saving costs. Our panels are resistant to all weather conditions, can be mounted on any sub-structure purlins (wood, steel, concrete, etc…), and quite suitable for renovating older non-insulated roofs. The panels feature a triple sealing system, offering optimum protection against condensation, and can be readily integrated with BRUCHA Fire Protection Roof panels (DP-F) without additional adapter profiles.

  • Rib profile/height: trapezoidal, 1-5/8″ (42mm)
  • Rib spacing: 13-1/8″ (333mm)
  • Metal gauge: 0.0236″ (0.6mm) – approx. 9% thicker than 26 gauge.  (Alternative metal gauges available upon request.)


  • Standard 25 μm polyester surface coating.  (Panels are shipped without a protective PVC film — if required, please specify with order.)
  • Standard profile 1 (Profile 2 and 3 available on request)
  • Metal gauge: 0.0197″ (0.5mm)  (Alternative metal gauges available on request)

insulation core

  • PIR rigid foam manufactured in continuously foamed process, approx. 95 % closed cells; shear resistant bond with steel sheet.
  • Absolutely no chlorofluorocarbons or halogenated chlorofluorocarbons; pentane foaming agent.
  • Density approx. 2.5lb/ft³ (40kg/m3)

panel connection

  • Formed external steel overlaps the adjacent panel’s outer rib profile. Steel overlap possesses a capillary break to inhibit moisture movement.
  • The special joint profile also overlaps panels at the inner connecting surfaces.
  • Integral Triple Sealing System provides additional reliability, achieving reliable tight connections and optimal condensation protection.
  • See diagram on Product Data Sheet for a visual description of panel connecting features.

testing & certifications
