A battened gate runs vertical battens between a welded steel frame, usually a rectangular hollow section (RHS) frame around the perimeter with one or more cross-rails inside. Battens are commonly aluminium extrusions in 50x16, 65x16, or 80x16 mm. Steel flat bar shows up on heavier or more traditional jobs.
Battens at small gaps screen most of the view but let air through, so a 3 m wide leaf isn't acting like a sail in the next storm. Spacing usually runs 8 to 25 mm. Pool-compliant gates run tighter, 95 mm or less between batten faces, which leaves safety margin against the AS1926.1 100 mm sphere test.
CAD60's battened gate models accept frame profile, batten profile, batten count, and batten spacing as separate inputs, then rebuild every dimension line in the drawing pack from your numbers.
