Acrylic Square & Rectangular Tubes
Square and rectangular PMMA tube for display cases, framing, light boxes and furniture components — anywhere a flat face is needed for bonding or mounting that a round tube cannot give.

How we make it hold up
Two process steps that do not show in a photograph and do not show in the box, but decide whether the part is still sound a year after you built it.
Every acrylic tube is annealed before it ships
Extrusion leaves stress frozen into the wall. You cannot see it in the box — it shows up later, as crazing round a drilled hole, a crack after solvent bonding, or a web of hairlines weeks after the part went together. We heat and slow-cool every acrylic tube to relieve that stress before it leaves the factory. It costs us a process step that a lot of extruders skip, and it is the reason our tube machines, bonds and cleans without going milky.
UV stabiliser and anti-ageing additive as standard
We run a UV stabiliser and an anti-ageing additive in our acrylic on every job, not as a priced option you have to know to ask for. PMMA is already the most weather-stable of the clear plastics; the additive package is what keeps it from yellowing at the edges over an outdoor service life.

Frequently asked
How is the size written?
Width × height × wall thickness in mm. A rectangular section such as 40×20×2 is 40 mm wide, 20 mm high, with a 2 mm wall.
How sharp are the corners?
Extruded corners carry a small radius — a perfectly sharp internal corner cannot be filled consistently. Tell us if corner radius matters to your assembly and we will confirm what the section holds.
