GA 1022 Aluminium Y-Section Trim - 26.0mm Gap

Handles Double-Skin and Thick-Panel Construction: Double-skin panel systems — where two layers of standard board are bonded or mechanically fixed together to achieve improved acoustic mass or structural rigidity — typically result in combined thicknesses of 24mm or more. The GA 1022 is the Y-section profile for these assemblies: at 26mm, the arms reach around the full combined thickness and grip both outer faces, providing the perimeter junction trim for panels that exceed the capacity of narrower profiles in the range.

Accommodates Panel Edges with Applied Seals and Build-Ups: Heavy-duty panel systems used in acoustic, fire-rated, or high-performance partition applications often have edge treatments applied before installation: acoustic gaskets, intumescent seals, or edge banding strips. The GA 1022’s wider gap means these build-ups can be present on the panel edge and the profile still fits cleanly over the full edge, maintaining contact on both faces of the panel at the junction without the edge treatment preventing proper engagement with the arms.

The Most Substantial Profile in the Y-Section Range: The widest gap produces the widest overall profile — a more prominent perimeter trim with greater visual presence. In environments where partition and boarding systems are designed to be robust and visually assertive, the GA 1022 provides a perimeter junction trim that is proportionate to the heavy-gauge panels it serves, rather than appearing visually undersized against a thick double-skin panel assembly.

Proven Durability for Demanding Installation Contexts: Heavy-duty panel systems are typically installed in demanding environments — sports halls, performance venues, industrial buildings, and large-scale public buildings — where perimeter trims are subject to regular physical contact, cleaning, and the general wear associated with high-traffic spaces. Independent testing by Ceram Building Technology (now Lucideon) confirmed anodised aluminium extrusion surfaces resist abrasion at up to four times the rate of mill finish, providing evidence-based confidence in the anodised GA 1022s for these applications.

Aluminium Construction for Long-Term Structural Compatibility: In heavy-panel installations with significant structural mass, the perimeter trim needs to be dimensionally stable and structurally compatible with the substrate it is fixed to. Aluminium does not creep, warp, or shrink with temperature change, ensuring the GA 1022 maintains consistent contact against the structural surface and panel faces over years of service without the loosening or gapping that can affect lower-density trim materials.
