Metal Decorative Trim Aluminum H Shape Edge Trim Decorative Profile

Aluminum H Shape Edge Trim for Clean Wall Panel Joints

This H shape trim is made for the seam between two adjacent wall panels. It sits in the gap, hides the cut edges, and leaves a straight, slim metal line that makes the joint look planned instead of patched. The profile is extruded from 6063-T5 aluminum alloy and anodized, so it stays light in the hand while keeping a firm shape along the full length of the wall.

It belongs to the 4mm series of LONGTE metal decorative trim, which also includes edge, inner corner and outer corner profiles, so one project can use a matching set from a single source.

Key Features of the H Shape Trim

Neat seam finish

The wide top flange covers the panel edges on both sides, so small cutting errors and uneven gaps stay out of sight. The result is a consistent line from floor to ceiling.

Anodized surface

Anodizing forms a hard oxide layer on the aluminum itself instead of a coat of paint on top. This layer resists scratches, humidity and daily cleaning, and it keeps the color even along the whole bar.

Moisture resistant and non-porous

Aluminum does not absorb water or swell, and its surface gives mold nothing to grow on. The trim is a sensible choice for hallways, living rooms, offices and other indoor walls where humidity changes through the year.

Lightweight and easy to work

The bar can be cut to length with a fine-tooth blade, then lightly deburred. Its low weight makes long runs easy to carry, hold and align on site.

Material and Finish

6063-T5 is a widely used architectural aluminum alloy known for smooth extrusion, stable dimensions and a fine surface after anodizing. That combination suits decorative profiles, where straightness and color consistency matter as much as strength.

Colors to Match Your Wall Panels

Matte gold adds a warm accent against walnut and oak grains. Rose gold suits soft neutral rooms and stone-look boards. Matte black draws a sharp graphic line on light panels, matte white blends into pale walls, and dark grey sits quietly between the two. Mixed orders are possible, so different rooms in one project can use different colors with the same profile.

Where to Use It

• Seams between PVC, WPC, bamboo charcoal and MCM wall panels
• Feature walls and TV backdrops in living rooms
• Hotel corridors, lobbies and reception walls
• Offices, showrooms and retail interiors
• Furniture, cabinet and door panel joints

Installation Guide

1. Measure the wall height and cut the profile to length.
2. Remove burrs from the cut end with a file or fine abrasive pad.
3. Place the first panel and leave a gap that matches the trim body.
4. Fix the trim in the gap using the adhesive or mechanical method that suits your wall system.
5. Fit the second panel against the trim and check that the top flange covers both edges evenly.
6. Wipe the surface with a soft damp cloth to finish.
