Aluminium U Channel – 1m Natural Mill Finish Edge Trim | 6mm to 25mm

This Aluminium U Channel provides a simple way to finish and protect the exposed edge of compatible boards, panels and sheet materials.

The U-shaped profile slides over the material edge to create a cleaner metal finish while helping protect vulnerable edges from everyday knocks and contact. With eight available sizes and approximate inside-gap measurements, customers can choose a channel based on the thickness of the board or panel they need to cover.

Every profile is supplied in a 1 metre / 100cm (39.37in) length with a natural raw mill finish. The aluminium can be left untreated for an industrial metal appearance or finished further where required.

Product Specifications

Available Sizes & Approximate Inside Gaps

Sizes are stated as outside base width x outside leg height x wall thickness.

The inside gap is approximate and is the most useful measurement when matching the channel to a board or panel thickness.

Problems This Aluminium U Channel Helps Solve

Exposed Board or Panel Edges

Raw MDF, plywood, melamine and sheet edges can look unfinished. The U profile covers the edge with a cleaner metal line.

Vulnerable Edge Damage

Panel and shelf edges can receive regular knocks during normal use. The aluminium channel adds a protective outer layer around suitable materials.

Difficulty Choosing the Right Channel Size

Outside dimensions alone do not tell customers whether their board will fit. The approximate inside-gap measurements make size selection easier.

Standard 18mm Board Edging

The 20x10x1mm profile has an approximate 18mm internal gap, making it particularly relevant for suitable standard 18mm boards.

Projects Needing a Stiffer Profile

The 20x10x1.5mm Heavy option uses a thicker wall for customers who need a more substantial channel in that size.

Benefits of This Aluminium U Profile

Eight Size Options

The range covers thin sheet materials through to thicker boards and panels.

Inside-Gap Guidance

Customers can compare their material thickness directly with the approximate internal opening rather than guessing from the outside profile size.

Natural Mill Finish

The untreated aluminium can be used as supplied for a raw metal appearance or painted or treated to suit the project.

Easy to Cut

The 1m profile can be shortened with a suitable fine-tooth hacksaw.

Flexible Installation

Depending on the project, the channel can be slid over the material edge and secured with suitable adhesive, small screws or rivets where required.

Applications

Suitable for compatible:

• MDF boards
• Plywood
• Melamine boards
• Panels
• Shelving
• Worktop ends
• Acrylic sheets
• Polycarbonate
• Thin sheet materials
• Furniture projects
• Decorative U moulding
• Model making
• Workshop projects
• General fabrication
• DIY builds

Installation Guide

1. Measure the thickness of the board, panel or sheet.

2. Choose a U Channel with an appropriate approximate inside gap.

3. Measure the edge and cut the aluminium profile to the required length using a suitable fine-tooth hacksaw.

4. Lightly file the cut end where required.

5. Slide the channel over the material edge and check the fit.

6. Where additional retention is required, use a suitable adhesive inside the channel or secure with small screws or rivets where appropriate.

For corner details, the profile can be mitred at 45° where suitable.

Before Ordering

The most important measurement is the thickness of the board or panel.

Compare this measurement with the approximate inside gap of the selected channel.

For example:

• A 10mm internal gap may suit a compatible board close to 10mm thick.
• The 20x10x1mm profile provides approximately 18mm of internal space.
• The heavier 20x10x1.5mm profile provides approximately 17mm because of its thicker walls.

Inside-gap measurements are approximate. If the board thickness is very close to the stated opening, consider whether the next suitable size gives enough fitting tolerance.

Also remember that the finish is raw mill aluminium, so light handling or manufacturing marks can be normal.

What Does the Customer Get from This Product?

The customer gets more than a simple decorative metal strip.

This product provides a U-shaped edge cover with size guidance based on actual internal clearance, making it easier to choose a profile that suits the material being edged.

The eight size options allow customers to finish everything from thin acrylic sheets to thicker furniture and panel boards, while the heavier 20x10mm version provides another option where a thicker aluminium wall is preferred.

Why Choose This Aluminium U Channel?

This profile is a practical choice for customers who need to protect, cover and finish the exposed edge of a board or panel.

Its wide range of sizes, approximate inside-gap measurements, natural aluminium finish and straightforward cutting make it suitable for furniture work, interior fitting and general fabrication projects.

Frequently Asked Questions

How do I choose the correct U Channel size?

Measure the thickness of your board or panel and compare it with the approximate inside gap of each profile.

What size suits an 18mm board?

The 20x10x1mm profile has an approximate inside gap of 18mm and may suit compatible 18mm board applications. Check the actual board thickness before ordering.

What is the difference between the two 20x10mm profiles?

The standard version has a 1mm wall and approximately 18mm inside gap. The Heavy version has a 1.5mm wall and approximately 17mm inside gap.

Is the aluminium anodised?

No. It has a natural raw mill finish and is not anodised.

Can the U Channel be cut to size?

Yes. Every profile is supplied in a 1m length and can be cut using a suitable fine-tooth hacksaw.
