What is expanded metal?

A solid steel sheet that has been slit and then stretched. The slits open into diamond cells — strong, light, and with no welds anywhere in it.

What cell sizes are available?

KRAFT Mesh comes in four mesh sizes: 16×8, 30×13, 42×14 and 60×20 mm. Open area runs 50%, 54%, 57% and 60% respectively, and weight from 4.56 to 5.14 kg/m². The material is galvanised steel to PN‑EN 13964:2014‑05.

What fixing systems are there?

Four main ones: LAY-ON T24 / LAY-IN T15 on a KRAFT Fortis grid, CLIP-IN on a concealed OMEGA carrier, HOOK LOCK on a concealed Z profile, and MESH CLOUD on threaded rod or wire. Hook Lock Corridor is a separate option for narrow spaces.

What is the fire rating?

Euroclass A2‑s1, d0 to EN 13501‑1. Steel panels do not burn, and the open structure lets smoke clear.

Can mesh panels go on a façade or a wall?

KRAFT makes fourteen fixing systems for façades and walls, GMA through GMN. Which one you use is decided project by project.

How do I improve the acoustics of a mesh ceiling?

Add SOUNDTEX® acoustic fleece: αw = 0.75, class C to ISO 11654; NRC = 0.80 and SAA = 0.81 to ASTM C423. It is self-adhesive and it does not change how the ceiling looks.

What are the standard panel sizes?

Standard KRAFT Mesh panels are 600×600 mm and 600×1200 mm. Mesh gauge 1.0 mm, coating 60–80 µm, suitable up to 95% relative humidity.

KRAFT Mesh expanded metal panels

Name: KRAFT Mesh expanded metal panels
Brand: KRAFT

Expanded metal panels: strong, light and open. They work on ceilings, walls, façades and partitions — letting light and air through, screening the services above, and holding a graphic line that reads from a distance.

Material

What expanded metal is

Expanded metal starts as a solid sheet. The sheet is slit and then stretched to size, and the slits open into diamond-shaped cells. Nothing is welded and nothing is joined — it is all one piece of steel. The mesh pattern is diamond or square.

That combination — strong, light and open — is why the material moved out of engineering and into architecture: façade cladding, ceiling and wall panels, partitions, balustrades and feature elements.

Sizes

Four mesh sizes

A cell is defined by four dimensions: H the width, A the height, K the strand depth and I the metal thickness. How they relate decides openness, strength and weight.

KRAFT Mesh cell sizes, panel weight and open area
Mesh	H×A×K×I, mm	600×600	1200×600	kg/m²	Open area
16×8	16×8×2×1	1.85 kg	3.70 kg	5,14	50%
30×13	30×13×3×1	1.64 kg	3.28 kg	4,56	54%
42×14	42×14×3×1	1.73 kg	3.52 kg	4,80	57%
60×20	60×20×4×1	1.68 kg	3.35 kg	4,65	60%

High-grade galvanised steel to PN‑EN 13964:2014‑05.

Orientation

The wave

Because of how the sheet is expanded, the cells come out elongated. Run them together and they read as a wave along one axis.

Why it matters

Which way the wave runs decides how much of the void you can see, and it changes both how the room reads and how the light falls.

How to use it

To hide the services, turn the cells so the plant zones disappear. To open the space up, turn them the other way.

Fixing

Four fixing systems

What separates the KRAFT Mesh systems is how the panel fixes to the structure. Panel sizes, steel and coating stay the same — only the frame and the carrier change.

LAY-ON T24 / LAY-IN T15

Panels lay into a KRAFT Fortis grid, 15 or 24 mm wide. With Lay-On the panel face finishes flush with the grid; with Lay-In it sits below the T‑bars.

Frame: Internal L‑shaped frame; tegular edge on Lay-In
Carrier: KRAFT Fortis T24 (24 mm) or T15 (15 mm)
Standard panel sizes: 600×600 mm, 600×1200 mm
Mesh gauge: 1.0 mm
Coating thickness: 60–80 µm
Fire: Euroclass A2‑s1, d0 to EN 13501‑1

Frame joint

How the mesh meets the frame

Three ways of joining the mesh to the panel frame.

Type I: into the frame

Used with LAY-ON T24, LAY-IN T15, Hook Lock, Mesh Cloud and CLIP-IN panels.

Type O: under the frame

Used with LAY-ON T24, LAY-IN T15, Hook Lock, Mesh Cloud and CLIP-IN panels.

Type R: to the rib

Used with Hook Lock panels only.

Façades

Fixing to façades and walls

There is more than one way to fix mesh to a façade or a wall, and each has its place. KRAFT makes fourteen fixing systems; which one you use is decided project by project.
