Galvanized Steel Profile 40x30x3000 mm – for Acoustic Wall Systems

A unique profile, designed for professional sound insulation

The 40x30x3000 mm galvanized steel profile was developed specifically to deliver optimal performance in high-efficiency acoustic wall systems.
With its 30 mm side designed for adhesive floor installation, it prevents direct contact with existing walls, helping eliminate structural sound bridges.

Why use this profile: key advantages

• Avoids acoustic bridges: the 30 mm depth keeps the profile from touching existing walls, which is critical in soundproof systems.

• Perfectly compatible with Stratifon and Fonobag panels:

  • Stratifon29 = 35 mm

  • Fonobag = 50 mm

  • Stratifon40 = 70 mm
    The profile stays within the panel thickness, preventing direct wall contact.

• Quick and clean installation: applied with high-strength double-sided tape — no drilling or screws needed.

• Multi-use: applied along the floor, ceiling, and walls, it hosts both soundproof panels and T-profiles.

Where and how it’s used

This profile is installed along the entire perimeter of the acoustic wall, creating a base to insert insulation panels (Stratifon29, Stratifon40, Fonobag) and support T-profiles.
Ideal for:

• High-performance acoustic partitions

• Rooms needing sound and vibration control

• Technical spaces, recording studios, offices, rehearsal rooms
