— TECHNICAL DEFINITION —
What are perforated metal baffles?
Perforated metal acoustic baffles are vertically suspended ceiling baffles made from perforated aluminum, galvanized steel, or stainless steel, with acoustic fleece or absorptive infill behind the perforated face. They are designed for echo reduction and reverberation control.
Important — the metal face itself is not the primary absorber. Sound absorption is achieved through the perforations, acoustic fleece or infill, internal cavity, and exposed baffle surfaces.

— SYSTEM COMPONENTS —
Metal Baffle System Components
Perforated metal baffles should be treated as a complete ceiling system, including the baffle body, carrying channel, suspension accessories, end caps, brackets, and acoustic backing or infill where required.
Perforated Metal Baffle
Aluminum, galvanized steel, or stainless steel baffle body with the selected perforation pattern.
End Cap
Closes the open ends of the baffle for a clean, finished edge.
Carrying Channel
Top rail that carries the baffles and ties the system to the ceiling structure.
Connecting Splice
Joins two carrying channels for continuous spans across longer runs.
Hanging Rod / Steel Cable
Suspension element that drops the carrying channel from the slab.
Closing Strip
Finishing strip that hides edges and tidies the perimeter of the baffle field.
C-Channel Bracket
Wall or slab bracket that anchors the carrying channel at room boundaries.
Acoustic Fleece / Infill
Black fleece or absorptive core behind perforations to drive sound absorption.
— PERFORATION —
Perforation Patterns
The perforation pattern controls both the visual rhythm of the ceiling and the available open area for sound absorption.
Slot Perforation
Elongated slot openings — strong linear visual rhythm and adjustable directional character.
Micro-Perforation
Very small dense perforations — near-solid appearance from a distance with high open-area absorption potential.
Custom Pattern
Bespoke patterns, logos, or graphic perforations for branded architectural ceilings.
Open area and perforation pattern should be selected according to acoustic target, visual design, cleaning requirements, fire requirements, and supplier test reports.
— INFILL OPTIONS —
Infill & Backing Options
The backing and infill behind the perforated face drive how much sound is absorbed by the baffle system.
Without Infill
For projects where the visual metal baffle form, durability, and ceiling rhythm are the main requirements.
With Acoustic Fleece
A practical option for improved absorption, dark backing appearance, and cleaner visual finish behind perforations.
With Acoustic Fleece + Infill
Recommended for stronger acoustic performance where reverberation control is a key requirement.
Final acoustic performance depends on perforation pattern, open area, cavity depth, backing, infill, baffle spacing, room volume, and certified supplier test reports.
— WHEN TO CHOOSE —
When to choose metal baffles
Perforated metal baffles are recommended when durability, cleanability, fire performance, impact resistance, corrosion resistance, and industrial architectural appearance are important. For softer interiors, PET or fabric baffles may be preferred.
