Profile & Optics
Profile design, optical characteristics and surface finish
Profile design
Snap-in, clip-on, lay-in and suspended cross-sections, plus asymmetric profiles for wall-wash and cove applications.
Optical characteristics
Transmission and diffusion set by material grade, wall thickness and surface structure. Ranging from near-clear to fully opaque.
Surface finish
Gloss, frosted, embossed or prismatic. Co-extruded surfaces combine a diffusing layer with a clear or coloured base.
Customization
What we can change for your project
Profile
New cross-sections developed from your drawing or from an existing sample.
Dimensions
Width, height, wall thickness and length set to your fixture geometry.
Surface
Gloss, frosted, embossed, prismatic or co-extruded surfaces.
Colour
Clear, opal, custom colours and two-colour combinations.
Applications
Typical applications
Linear lighting
Continuous runs in offices, retail and industrial spaces.
Architectural lighting
Cove, wall-wash and feature profiles.
Commercial lighting
Downlights, panels and suspended fixtures.
Troffer lighting
Recessed luminaires needing even, low-glare output.
Industrial lighting
High-bay and warehouse fixtures.
LED strip lighting
Covers and housings for flexible and rigid strips.
Cabinet lighting
Under-cabinet and shelf profiles.
Signage lighting
Edge-lit and back-lit signage.
Manufacturing Process
From drawing to packed profile
Drawing
2D drawing, 3D file, sketch or an existing sample.
Material
PC or PMMA, single-colour or two-colour, selected for optics, impact and UV stability.
Tooling
In-house die design and die manufacturing.
Extrusion
Trial run and parameter setting on a matched extrusion line.
Cutting
Cut to length, mitring, notching, drilling and CNC machining.
Inspection
Dimensional, appearance and optical checks against the approved sample.
Packaging
Protective film, sleeving, cartons and pallets to your requirement.
Quality Control
How the profile is checked
- Incoming resin inspection and batch traceability
- First-piece approval against the approved sample or drawing
- In-process dimensional checks on profile width, height and wall thickness
- Light transmission and haze measurement on optical grades
- Appearance inspection under standard lighting conditions
- Final random inspection before packing and palletising
