Metal Grilles & Diffusers

They are outlets and inlets that distribute or collect conditioned air. Metal construction provides strength, precision, and durability, making them ideal for both residential and commercial projects.

Metal grilles offer superior rigidity, long service life, and a more premium finish. They are suitable for high-traffic or commercial spaces and can be powder-coated in custom colours to match interior design.

Yes. Metal grilles and diffusers can be manufactured with precise blade angles and profiles that optimise throw, spread, and air mixing. This ensures efficient and quiet performance.

Options include bar grilles, louvred grilles, egg-crate return grilles, swirl diffusers, and linear slot diffusers. Styles can be fixed, adjustable, or architectural-grade for aesthetics.

In Australia, AS 4254 and AS 1668 system requirements apply. Internationally, ISO 5219 governs air diffusion performance, and fire testing may reference BS 476 or EN 13501.

They can be cleaned with a vacuum or damp cloth and periodically checked for dust buildup. Powder-coated finishes resist wear, but screws and fixings should be inspected to ensure secure mounting.

Staark grilles are engineered with precision blade angles for optimal airflow and are manufactured using durable coated metals to resist wear and corrosion. Unlike generic imports, they are tested to AS 4254/AS 1668 standards, available in a wide range of finishes, and backed by local technical support — ensuring performance, compliance, and aesthetics in every installation.
