The LC-ST-40A is a 40mm depth single-sided SEG aluminum profile engineered for standard wall-mounted
backlit fabric lightboxes. Manufactured from premium 6063-T5 aluminum alloy, it features a dedicated
internal LED strip mounting track that supports even light diffusion and consistent brightness across the
display surface. Weighing only 0.42kg per meter, it balances structural rigidity with easy handling and
installation. The precision-engineered silicone edge groove holds SEG graphics firmly for a perfectly
flat, frameless visual effect. This profile is compatible with standard LED strip widths and diffuser
panels, making it a versatile choice for retail storefront signage, commercial advertising displays, and
indoor brand promotion lightboxes. It supports custom length cutting and is compatible with standard
aluminum profile bending and powder coating services.
Where LC-ST-40A fits
LC-ST-40A covers the narrow end of the single-sided range at 40 mm — shallow enough for a framed poster above a counter, deep enough to hide the SEG bead behind the fabric. It carries a single silicone-edge graphic, so the specification stays simple — frame, corners, connectors, fabric — with nothing behind the panel to service later.
Build, finish and compatibility
Extruded in 6063-T5 aluminum with a machined SEG channel; standard finish is silver anodised, with black, white or a RAL powder coat available on request, 0.42 kg per metre. Corner pieces and connectors from the same family close the frame with a friction fit, so a 1 × 2 m panel assembles on site with an Allen key and no welding.
Cutting, packing and lead time
We cut to length before packing — 3.5 m, 5 m or 6 m (custom lengths on request) as standard — and bundle each order in a plastic sleeve plus kraft paper so the anodised face arrives without scuffing. Stock sections are quoted within 24 hours; custom colours and cut lists run 15–25 days, and a sample length can be sent before you commit to the full frame.
