Finishing profiles, as complete systems.

The decorative and finishing aluminium profiles, curated by family. The point: stop treating these as individual metal strips and organise them as complete junction systems — profile + corners + joiners + end caps + fasteners + install method + compatible material thickness.

Standard sizes and conventions only — no SKUs, brands or prices. Sizes state the visible face; bar length is managed in linear metres; alloy/temper and a custom colour (e.g. Champagne) are recorded against an approved master sample. A movement joint is a structural profile, never a decorative T-strip.

10 profiles — each a complete junction system (profile + corners + joiners + end caps + fasteners). Source and verify against a supplier; ELS states no SKU.

T10 decorative T-lineStandard stock
Symmetrical T — flat ~10 mm top face, single central stem that seats into the panel seam / groove
Sizes
Visible face: ~10 mm — the flat top shown on the panel (the name is the face width, not the seam)Stem / insertion depth + stem thickness: record (model-dependent) — stem depth must be ≤ panel thicknessCompatible panels: for ~5 / 8 / 9 mm wall panels; matching seam / groove width — recordBar (stock) length: 2.4 / 2.5 / 2.7 / 3.0 m — manage stock in LINEAR METRES, not pieces
Alloy / finish
Aluminium extrusion — record alloy / temper + wall thickness + extrusion toleranceFinish: anodised / powder-coated / film-wrapped — state which per colourStandard colour Matte Black; Champagne / brushed / custom needs an approved physical master sampleWet / exterior use: specify marine-grade anodised or exterior-grade powder-coat
System components
  • Matching end caps / terminations (profile-specific to T10)
  • In-line joiner / alignment spline for butt-joining bars in a long run
  • Corner: 45° site mitre, or a moulded 阴角 / 阳角 corner if the range offers one
  • Neutral silicone / structural adhesive to bond the stem (not double-sided tape alone for load)
  • Wedge spacers to hold the seam width while curing
  • Mitre jig / 45° cutting guide for clean corners and butt joints

Use: Decorative reveal lines on WPC / bamboo-charcoal / laminate wall panels — feature-wall grids, panel-seam concealment, TV and headboard feature lines

Not for — A decorative T-line is NOT a movement / expansion joint — never use it to bridge a structural or thermal movement gap

To source & verifyConfirm the number is the VISIBLE FACE width (not seam / insertion depth) + compatible panel thickness + bar length in linear metres

T15 decorative T-lineStandard stock
Symmetrical T — flat ~15 mm top face, single central stem seating into the panel seam / groove; the boldest of the standard T-lines
Sizes
Visible face: ~15 mm — the flat top shown on the panel (the name is the face width)Stem / insertion depth + stem thickness: record (model-dependent) — stem depth ≤ panel thicknessCompatible panels: for ~8 / 9 / 12 mm wall panels; matching seam / groove width — recordBar (stock) length: 2.4 / 2.5 / 2.7 / 3.0 m — manage stock in LINEAR METRES, not pieces
Alloy / finish
Aluminium extrusion — record alloy / temper + wall thickness + extrusion toleranceFinish: anodised / powder-coated / film-wrapped — state which per colourStandard colour Matte Black; Champagne / brushed / custom needs an approved physical master sampleWet / exterior use: specify marine-grade anodised or exterior-grade powder-coat
System components
  • Matching end caps / terminations (profile-specific to T15)
  • In-line joiner / alignment spline for butt-joining bars in a long run
  • Corner: 45° site mitre, or a moulded 阴角 / 阳角 corner if the range offers one
  • Neutral silicone / structural adhesive to bond the stem
  • Wedge spacers to hold the seam width while curing
  • Mitre jig / 45° cutting guide for clean corners and butt joints

Use: Bold reveal lines and wider grid divisions — taller feature walls, wardrobe and joinery face lines, reception and headboard backdrops

Not for — A decorative T-line is NOT a movement / expansion joint — never use it to bridge a structural or thermal movement gap

To source & verifyConfirm the number is the VISIBLE FACE width (not seam / insertion depth) + compatible panel thickness + bar length in linear metres

T5 decorative T-lineLimited qty
Symmetrical T — slim ~5 mm top face, shallow central stem into a fine panel seam; the finest reveal line
Sizes
Visible face: ~5 mm — a fine hairline reveal on the panel faceStem / insertion depth is shallow — record; suited to fine, even seams onlyCompatible panels: for ~5 / 8 mm wall panels; fine matching seam width — recordBar (stock) length: 2.4 / 2.5 / 2.7 / 3.0 m — manage stock in LINEAR METRES
Alloy / finish
Aluminium extrusion — record alloy / temper + wall thickness + extrusion toleranceStocked in Matte Black only — any other colour (incl. Champagne) is a separate added line, not standard T5A Champagne / custom colour needs an approved physical master sample and batch matchingFinish: anodised / powder-coated / film-wrapped — state which
System components
  • T5-specific end caps (kept in limited qty)
  • In-line joiner / alignment spline matched to T5
  • Neutral silicone / structural adhesive for the shallow stem
  • Wedge spacers to keep the fine seam even
  • Mitre jig for clean 45° corners (bar is mitred; no separate corner)

Use: The finest decorative reveal — tight panel grids, delicate feature lines and shadow-gap detailing where T10 / T15 would look heavy

Not for — Shallow stem — do not use T5 to bridge a wide or uneven seam; it will not hold. It is a decorative line, never a movement / expansion joint

To source & verifyConfirm Matte Black stock (the only standard T5 colour) + visible face ~5 mm + fine seam width + bar length in linear metres

T5 Champagne T-line (added colour)Order by project
Same T5 symmetrical section — slim ~5 mm face — offered in Champagne; a colour addition to the standard Matte-Black T5, not a different section
Sizes
Visible face: ~5 mm — identical section to standard T5Compatible panels / seam: as standard T5 (~5 / 8 mm panels; fine seam) — recordBar (stock) length: 2.4 / 2.5 / 2.7 / 3.0 m — linear metres; MOQ + lead time apply as a colour add
Alloy / finish
Champagne finish (anodised or coated) — requires an APPROVED physical master sample before order + batch-to-batch colour matchingAluminium extrusion — record alloy / temper + wall thicknessColour consistency is batch-sensitive — order one run for a whole job where possible
System components
  • T5 end caps + joiner in the matching Champagne batch
  • Approved physical master sample retained on file
  • Neutral silicone / structural adhesive
  • Wedge spacers for the fine seam
  • Mitre jig for 45° corners

Use: Warm metallic reveal lines where Matte Black is too hard — Champagne feature walls, joinery faces, hospitality and retail interiors

Not for — Do not order without an approved master sample, and do not mix colour batches on one visible run — visible colour mismatch. Not a movement joint

To source & verifyApproved physical Champagne master sample on file + single-batch colour match + same T5 section / seam + bar length in linear metres

In-line joiner / alignment splineStandard stock
Short backing splice / connector bridging two T-line ends behind the seam to keep the top faces flush and aligned across a straight butt joint
Sizes
Profile-specific — matched to the back geometry of T5 / T10 / T15; recordHidden component: no visible face; length just spans the joint — record
Alloy / finish
Aluminium or rigid polymer spline — record; the joiner is concealed, so finish is not colour-critical
System components
  • The two T-line bars it aligns
  • Neutral silicone / adhesive to lock the splice
  • Wedge spacers to hold face-flush while curing

Use: Butt-joining T-line bars into a run longer than one stock length while keeping the face line unbroken

Not for — Straight in-line joints only — not a substitute for a corner; do not use it to turn a corner

To source & verifyJoiner is profile-specific — confirm it matches this T-line's back geometry; otherwise align by squared butt + adhesive

End cap / clean terminationStandard stock
Small cap closing the exposed end of a T-line run, matching the bar's face + stem cross-section
Sizes
Profile-specific: a separate cap for T5, T10 and T15 — the cap must match the exact face widthUsed only where a run ends at an open / exposed edge (not at butt joints or corners)
Alloy / finish
Aluminium or colour-matched injection moulding — record; must match the bar's finish + colour batch
System components
  • The T-line it terminates (batch-matched)
  • Dab of neutral silicone / adhesive to retain the cap
  • Deburred, squared bar end to seat the cap

Use: Closing the visible end of a T-line where it stops at a panel edge, door / window reveal, or ceiling line

Not for — Not structural — the bar must be independently bonded; the cap only closes the end, it does not hold the T-line

To source & verifyEnd cap is profile-specific and colour-matched — confirm the cap matches this exact T-line (T5 / T10 / T15) and finish batch

Corner treatment — internal 阴角 / external 阳角Order by project
The 90° junction where two T-line runs meet at a wall corner; standard = 45° mitre of the profile itself, optional moulded corner piece if the range offers one
Sizes
Stated angle: internal (阴角, concave) vs external (阳角, convex) — 90° typical; other angles recordFace width must equal the running T-line (T5 / T10 / T15) for a continuous lineMoulded-corner leg length (if used) — record
Alloy / finish
If a moulded corner: same alloy / finish + colour batch as the run — record and matchMitre cuts expose bare aluminium at the cut — seal / touch-up per finish
System components
  • Mitre jig / fine-tooth saw for 45° cuts
  • Neutral silicone / structural adhesive
  • Touch-up / edge seal matched to the finish
  • Non-marring clamps while curing

Use: Turning T-line reveals around internal and external wall corners on feature walls and panel grids

Not for — Do not force / bend a rigid T-line around a sharp corner (kinks the face) — mitre it or use the corner part; a corner is not a movement joint

To source & verifyStated angle 90° internal (阴角) vs external (阳角) + whether a moulded corner exists or it is a site 45° mitre + surface vs panel-inserted seating

45° mitre jig / cutting guideOrder by project
Cutting / holding jig, not a profile — repeatably sets 45° (corner) and 90° (butt) cuts on the T-line without crushing the face
Sizes
Sized to grip the T5 / T10 / T15 face + stem — record the profile range it fits (no bar length)Blade kerf allowance — record so mitres close tight
Alloy / finish
Jig body — record material; jaws must be non-marring to protect anodised / coated facesFine-tooth non-ferrous blade recommended for clean aluminium cuts — record
System components
  • Fine-tooth mitre saw or hand mitre box
  • Non-marring clamps
  • Deburring tool / fine file for cut edges

Use: Fabricating clean corners and in-line butt joints for T-line runs on site or in the workshop

Not for — Not a fixing component — it shapes cuts only; do not leave it in the finished junction

To source & verifyJig fits this profile's face + stem and grips without marring the finish

Flexible / site-bendable T-lineOrder by project
Slotted (kerfed) or soft-core T-line that follows a curved panel seam or arch; face width matches a rigid T for a continuous line
Sizes
Visible face: matches the paired rigid line (e.g. ~10 mm) — state which rigid T it continuesMinimum bend radius — record; state factory-curved vs site-bendableBar / coil length: manage in LINEAR METRES
Alloy / finish
Kerfed aluminium or aluminium-look flexible polymer — record; confirm whichFinish must colour-match the rigid T-line's approved master sample
System components
  • The rigid T-line it continues (colour / finish batch-matched)
  • Neutral silicone / structural adhesive
  • Forming template / former to hold the radius while curing
  • Wedge spacers

Use: Curved feature-wall seams, arched openings and circular columns — where a rigid T cannot follow the curve

Not for — Not for radii tighter than its rated minimum bend radius (kinks / cracks the face); not a structural curve-former

To source & verifyMin bend radius + factory-curved vs site-bendable + colour-match to the rigid T-line master sample

Seating & spacing kit (install system)Standard stock
Install / fastening system, not an extrusion — neutral silicone or structural adhesive + wedge spacers + low-tack masking tape; how every seam-inserted T-line is actually fixed
Sizes
Adhesive bead size + spacer thickness set the seam width — record per panel / seam (no bar length)Coverage per linear metre of seam — record
Alloy / finish
Neutral-cure (oxime / alkoxy) silicone or approved structural adhesive — NOT acetic ('vinegar') cure on aluminium; state product per substrateWedge spacers + low-tack masking tape + substrate cleaner / primer per manufacturer
System components
  • The T-lines it seats (T5 / T10 / T15)
  • Solvent / primer matched to the panel substrate
  • Wedge spacers sized to the specified seam width

Use: The standard way every seam-inserted T-line is fixed and spaced — kept as a consumable alongside the profiles

Not for — Do not use acetic-cure silicone on anodised aluminium (corrosion); do not rely on thin double-sided tape alone to carry a vertical / overhead T-line

To source & verifyAdhesive is neutral-cure and substrate-approved + spacer set matches the specified seam width

Per profile

What every profile record should carry

A profile is a system, not a length. Record it as: profile + corners + joiners + end caps + fasteners + install method + compatible thickness.
