A 27mm Domal Section refers to an aluminum extrusion profile, typically 27mm in height, used in the fabrication of sliding windows, particularly those with multiple tracks. These sections are commonly used in residential and commercial applications, offering a slim and strong profile design for smooth sliding window functionality. 

Key features and characteristics:

• Dimension:

  27mm in height, though the overall profile may be wider depending on the specific design. 

• Material:

  Typically made of high-grade aluminum alloy for strength and durability. 

• Application:

  Primarily used for sliding window systems, including those with 2-track, 3-track, and 4-track designs. 

• Surface Finish:

  Available in various finishes like anodized, powder-coated, and other coatings. 

• Benefits:

  • Precision: Extruded to exact tolerances for perfect alignment and smooth sliding. 
  • Durability: Strong and resistant to corrosion, making them suitable for various environments. 
  • Aesthetics: Slim profile design adds to the overall look of the window.
