The heavy-duty perforated sheet metal is great for indoor use. It's essentially a metal sheet with round holes known as a 'perforated pattern'. The raw steel material and holed feature make it great for airflow management, but please keep in mind that it's unfinished and untreated surface means it isn't rust resistant and can oxidise overtime if placed outdoors. With 2 lengths available (500mm and 1000mm), it's perfect for a variety of rooms.

Please note, no fittings are included with this product.

Where to use:

• Ventilation panels
