Grey Rigid PVC Sheet (PVC-U) | 1.5–50mm | Cut to Size | UK Stock

Grey Rigid PVC Sheet (PVC-U) | 1.5–50mm | Cut to Size | UK Stock

Solid grey rigid PVC-U sheet in RAL 7011, stocked in 17 thicknesses from 1.5mm to 50mm and 11 panel sizes from 250×250mm up to full 3000×1500mm sheets. Colour runs right through the material — this is solid PVC, not foamed. All pieces are cut square and despatched from UK stock.

Which thicknesses come in which sizes

Not every thickness is stocked in every panel size. Check here before you select, to save picking a combination we cannot supply:

Note: 4.5mm and 9mm are stocked in the 2440×1220 full sheet only. If you need a thickness and size combination that is not listed, contact us for a custom cut quote — we can usually cut it from a full sheet.

Key Properties

• Material: solid rigid PVC (PVC-U / unplasticised PVC), colour through
• Colour: grey, RAL 7011
• Self-extinguishing — UL94-V0 rated
• Excellent chemical resistance to acids, alkalis and most solvents
• Good electrical insulating properties
• Low water absorption, high dimensional stability
• Operating temperature: 0°C to +60°C
• Easily machined, welded and bonded
• Supplied without protective film — minor surface marks are normal on industrial grade

Material Specifications

Thickness Tolerances

Extruded PVC sheet is supplied to the following thickness tolerances. Allow for these when specifying machined parts or close-fitting assemblies:

Tolerances for 4.5mm and 9mm are not separately published — contact us if these are critical to your application.

Sheet Weights

Rigid PVC weighs approximately 1.4kg per m² per mm of thickness. To estimate the weight of any piece: length (m) × width (m) × thickness (mm) × 1.4 = weight in kg.

Cutting and Fabrication

Rigid PVC machines cleanly using standard woodworking or metalworking tooling — circular saws, jigsaws, drills, routers and mills all work well. For the best finish use carbide-tipped blades with 10–20mm tooth spacing and keep feed rates moderate to avoid melting the cut face.

• Saw allowance: allow at least 4mm for the width of the saw cut when calculating how many pieces you can take from a sheet.
• Bonding: degrease edges and bond with solvent cement or contact adhesive.
• Welding: PVC welding rod gives continuous butt or fillet welds.
• Bending: possible when warm (line bender or oven). Cold bending will crack the sheet.
• Not suitable for: laser cutting — PVC releases chlorine gas when lasered and will damage the machine.

Choosing a Thickness

1.5–3mm suits linings, templates and light panels. 4–10mm covers the majority of general fabrication, guards and tank work. 12–20mm is used where rigidity matters over longer spans. 25–50mm is for load-bearing components, machined parts, spacers and mounting blocks.

Typical Applications

• Chemical plant linings, tanks and ducting
• Laboratory furniture and splash-back panels
• Machine guards, covers and safety panels
• Signage, display boards and templates
• Wall cladding and protective linings
• Electronic enclosures and insulators
• Mounting plates, spacers, jigs and fixtures
• Fabricated fittings, valves and components
• Battery boxes and acid-resistant trays

Frequently Asked Questions

What is the difference between solid and foamed PVC?
This is solid (rigid) PVC-U — dense, strong and suitable for structural and chemical use. Foamed PVC (Foamex, Palight) has a cellular core, is far lighter and weaker, and is intended for signage and display. They are not interchangeable.

Can I use this outdoors?
Rigid PVC performs best indoors. It is usable outdoors but will gradually chalk and fade with prolonged UV exposure, and it becomes brittle below 0°C. For sustained outdoor use, ask us about UV-stabilised grades.

Is it food safe?
Standard industrial grey PVC-U is not supplied as food-contact approved. Contact us if you need a food-grade certified material.

Can it be laser cut?
No. PVC releases hydrogen chloride when lasered, which is harmful to operators and corrodes the machine. Saw, rout or mill it instead.

How do I glue PVC to PVC?
Use a solvent cement made for rigid PVC. Degrease and lightly abrade both faces first. For PVC to a dissimilar material, use a two-part structural adhesive.

Why does my sheet have light surface marks?
Industrial grade PVC is supplied without protective film, so light scuffing is normal and does not affect performance. If you need a cosmetically perfect face, tell us before ordering.

Do you cut to a size that is not listed?
Yes. Send us your dimensions and thickness and we will quote a custom cut, usually from a full sheet.
