ML-300 3" Trapezoidal Panel
3" Trapezoidal panels can be factory formed and/or fabricated, for all substrates, at project locations. Utilizes concealed fasteners with a floating clip system.
Built to withstand the toughest conditions, our 3″ Trapezoidal standing seam panel is engineered for structural durability. Constructed from high-quality materials, this panel offers exceptional strength, ensuring stability and support for your building structure.
Designed to fend off the elements, including rain, wind, and UV rays, this panel provides superior weather protection for your building. With its robust construction and tight seams, it forms a barrier against moisture infiltration, preventing damage and preserving the integrity of your structure.
Engineered for durability and longevity, this panel offers years of reliable performance with minimal maintenance. Its durable finish resists fading, chalking, and corrosion, maintaining its aesthetic appeal for years to come. With our panel, you can enjoy peace of mind knowing that your building is built to last.
Unlike exposed fastener systems, our concealed fastening panel offers a sleek, streamlined appearance with no visible fasteners. This not only enhances the aesthetic appeal of your building but also provides added protection against water intrusion and potential damage.
In addition to structural durability, weather protection, and longevity, our 3″ Trapezoidal Standing Seam Panel offers numerous other benefits:
- Versatility: Suitable for a wide range of applications, including roofs, walls, and facades.
