The LC-ST-40CA is a reinforced 40mm depth single-sided SEG aluminum extrusion built for medium-sized
backlit fabric displays requiring extra structural stability. Constructed from 6063-T5 aluminum alloy with
a thicker wall design, it weighs 0.48kg per meter and delivers improved torsion resistance for larger
format wall installations. Its internal cavity accommodates standard LED strips and diffuser sheets,
producing uniform, shadow-free illumination for SEG graphics. The precision-machined silicone edge slot
ensures tight fabric tension and a seamless frameless appearance. This profile is ideal for indoor
commercial advertising, shopping mall brand displays, and corporate office lobby lightboxes where
durability and consistent flatness are critical. It is available in standard 6.1m bars and supports custom
cutting, punching, and surface finishing services to match project specifications.
Where LC-ST-40CA fits
At 40 mm deep, LC-ST-40CA sits in the slimmest bracket of the range — the profile we quote for poster swaps in retail aisles, lift-lobby panels and office wayfinding, where a 2 cm shadow line around the graphic is already too much. Because the face is single-sided, the back of the frame is closed and mounts straight onto plasterboard, MDF or a metal sub-frame with no cavity behind it.
Build, finish and compatibility
Extruded in 6063-T5 aluminum, anodised and cut on our own lines, 0.48 kg per metre; wall thickness and ribbing are sized so the section stays true over a 3–5 m span when the fabric is tensioned. 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.
Specification snapshot
LC-ST-40CA is a single-sided frame, at 40 mm depth, 0.48 kg per metre, in 6063-T5 aluminum; bars come at 3.5 m, 5 m or 6 m (custom lengths on request), packed in plastic/kraft paper.
Q: Does LC-ST-40CA take LED lighting?
A: No — LC-ST-40CA is a non-illuminated SEG frame. For a lit panel, step up to a double-sided profile with an LED row and diffuser.
Q: What lengths and colours can I order?
A: 3.5 m, 5 m or 6 m (custom lengths on request), cut to your list; colours are silver, black, white or a custom colour.
Q: How fast is a quote and a sample?
A: Quote within 24 hours of a drawing or size list; stock ships in 3–5 days, custom coating 15–25 days, and sample pieces go out before bulk.
