Satin Aluminum H Bar for Tile, Wood and Stone Seams

Where two boards meet, the gap is either hidden or designed. This H section bar takes the second route. It drops into the joint, locks the two edges apart at a fixed distance, and shows a slim colored line on the surface. Instead of a caulk bead that yellows, the seam becomes a deliberate feature that frames each board.

The bar is extruded aluminum with an anodized color layer and a soft satin look. It is offered in black, champagne gold, gunmetal grey and rose gold, so the line can either disappear into the surrounding tone or stand out as an accent.

What the H Section Does

Holds a constant gap

The center web keeps the boards a set distance apart, so the reveal stays the same width over the whole run. Uneven spacing is one of the first things the eye notices on a long wall or floor, and the web removes that risk.

Covers the raw edges

Cut tile edges, sawn board cores and rough stone faces sit inside the channels on both sides. Only the clean top face is visible.

Leaves room for movement

Boards and tiles expand and shrink slightly with temperature and humidity. A bar with a defined gap gives them space to do so without pushing against each other.

Wears well

The anodized layer is part of the aluminum surface, not a film laid on top. It does not peel, and it takes routine wiping without losing color.

Choosing a Color

Matte white is also made for projects that want the line to fade into a light wall. Ask for a color card or a sample bar to test against your own material in daylight and in the room lighting.

Product Overview

Design Ideas

• Run a gold bar between large format tiles in a hotel corridor for a luxury grid
• Use black bars between pale wood panels to create a bold vertical rhythm on a feature wall
• Set a grey bar at the meeting point of tile and wood floor in an open plan room
• Add rose gold lines to a cabinet front or wardrobe door to split large surfaces
• Divide a ceiling into panels with a thin line that matches the lighting trim

Fitting the Bar

1. Mark the seam line and check that the substrate is flat and dry.
2. Cut the bar a little shorter than the run and file off any burr.
3. Fix the bottom flange to the substrate with adhesive or small fasteners.
4. Slide the first board against the web and check that it sits square.
5. Repeat with the second board, keeping both edges tight to the center web.
6. Wipe off residue with a soft cloth before it dries.

Packing and Supply

The bars are packed in reinforced cartons to keep corners and color layers free of dents and scuffs in transit. LONGTE has made aluminum profiles for 20 years, with skirting, wall panel profiles, decorative trims and mirror frame profiles in one catalog, and over 500 styles on the shelf. If your project needs a different width, length or color, send a drawing or sample and the team will confirm what can be produced.

Common Questions

Is the bar suitable for floors?

This listing is aimed at indoor walls, panels, cabinets and ceilings. For floor transitions with foot traffic, tell us the load and board thickness so the right profile can be suggested.

Will the color match my boards exactly?

Anodized colors are close to the standard shades shown here. For an exact match, send a sample and ask for a trial bar before a bulk order.

How is the bar cut?

A fine tooth saw or a metal cutting blade works well. File the end lightly so the bar enters the gap smoothly.

Can I mix several colors in one project?

Yes. Different colors share the same profile, so rooms can use different tones without changing how the bars are fitted.

Do you offer free samples?

Yes. Send your color and size needs and we will arrange a sample.
