PANEL TYPES
The S-Rib is a narrow, horizontally grooved panel that mimics the appearance of timber cladding. The distance between the horizontal grooves is 125 mm, making it one of the most popular choices for garage door designs.
Available surface finishes for S-Rib panels include:
- Woodgrain panels: Offered in four standard colours — White RAL 9016, Anthracite Grey RAL 7016, Sepia Brown RAL 8014, and Black RAL 9005
- Smooth surface panels: Available in three standard colours — White RAL 9016, Anthracite Grey RAL 7016, and Black RAL 9005
- STUCCO panels: Textured finish available in White RAL 9002, Sepia Brown RAL 8014, Anthracite Grey RAL 7016, and Silver RAL 9006
Custom RAL colours are available upon request for an additional charge.

Panoramic panels feature a modern design and provide maximum natural daylight for your building. Industrial sectional doors made with glazed profiles can function as viewing windows or act as semi-transparent partitions within a structure. Glass inserts are also available in a variety of tints upon request.
