PVC Channels, Sections & Box Profiles – U Channels, H Sections, C Channels & Box Sections (UK Made)

Our range of PVC channels, plastic sections and box profiles includes high-quality U channels, H sections, C channels and PVC box sections, manufactured in the UK from durable rigid uPVC. These profiles are designed for secure panel joining, edge protection and structural finishing across trade and DIY installations.

PVC channel and box section profiles are widely used for wall panel installations, sheet material edging, cladding systems, partition joining, garage conversions, shopfitting and caravan interiors. Whether you require a plastic U channel to hold panels in place, an H section to join two boards, a C channel for edge containment, or a PVC box section (square tube) for lightweight structural framing, these white plastic profiles provide a clean and professional finish.

All profiles are:

• Manufactured from strong rigid uPVC
• Moisture and corrosion resistant
• Suitable for indoor and sheltered outdoor applications
• Easy to cut, drill, bond and install
• Available in multiple sizes and wall thicknesses
• Manufactured and supplied in the UK

What Are PVC Channel & Box Sections Used For?

Plastic U channels, H sections and box sections are commonly used to:

• Join bathroom wall panels
• Secure cladding sheets
• Create clean board-to-board connections
• Protect exposed panel edges
• Provide lightweight framing support
• Build custom enclosures and display structures

PVC box sections (also known as square tube profiles) are particularly useful where a neat, enclosed structural profile is required without the weight or corrosion risk of metal.

Because uPVC does not warp or rust, these plastic channel and box profiles are ideal for bathrooms, utility rooms, garages, commercial interiors, exhibition builds and caravan installations.
