VisioMod Lineo — Horizontal Aluminium Fence

VisioMod Lineo is a horizontal aluminium slat screen built around a 40 × 40 mm 6063-T5 frame and 20 mm hollow extruded slats — engineered as a non-load-bearing boundary system that delivers privacy, wind filtration and a continuous architectural line across spans of up to 2500 mm between posts. The three slat widths — 30, 50 and 80 mm — are not aesthetic variants but optical calibrations: the 30 mm profile reads as a fine louvre with a 1:1 gap-to-face ratio that retains airflow and breaks wind-driven turbulence; the 50 mm profile is the default for residential privacy at 1:0.5; the 80 mm profile gives a near-solid plane (1:0.2) for street boundaries and pool decks where visual closure is the priority. Across all three widths the slat depth stays at 20 mm, so the shadow line, frame reveal and post profile remain dimensionally coordinated regardless of slat selection. Structural design follows EN 1991-1-4 with the relevant National Annex applied to terrain categories II–IV inland and Category 0 coastal. The standard 1.0 kN/m² wind tier covers inland sites; the 1.4 kN/m² coastal tier upgrades posts from 60 × 60 mm to 80 × 80 mm and tightens span at 1800 / 2000 mm heights. Foundation is specified two ways: an M12 chemical or expansion anchor through a 150 × 150 × 8 mm base plate onto a frost-protected reinforced slab, or a 60 × 60 / 80 × 80 mm post concrete-set 500 mm (Zone 1) to 700 mm (Zones 3–4) below grade per local frost depth. Frame and slat extrusions are mechanically fastened — fence-class fabrication, with EN 1090-1 explicitly not invoked. The finish system is Qualicoat Class 2 powder coat in any RAL, providing 50 % gloss retention after 3-year Florida exposure, with Qualimarine pre-treatment (2 g/m² etching) specified within 5 km of saltwater. Three woodgrain laminates — Walnut, Oak and Anthracite Wood — are sublimation-fused with 10-year colour-fastness against UV.
