Profile & Optics
Profile design, optical characteristics and surface finish
Profile design
Snap-in, clip-on, lay-in, wide-span and curved cross-sections.
Optical characteristics
Even, hotspot-free output along the run. Transmission set to the efficacy target of the fixture.
Surface finish
Frosted and embossed faces for diffusion; gloss faces where clarity is needed.
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.

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
