Galvanised steel perforated sheet with 3.5mm hexagonal holes, 4.5mm pitch, and 1mm thickness. Offers high airflow and corrosion resistance in a strong, compact format.
Perfect for vents, screens, guards, and decorative use in industrial, architectural, and custom-built applications.
This galvanised steel hexagonal perforated metal mesh features a compact 3.5mm hexagonal hole, a 4.5mm pitch, and a 1mm thick base sheet, delivering an excellent balance between airflow, strength, and filtration. The hexagonal holes are arranged in straight rows parallel to the sheet’s length, providing a neat, uniform layout that is both practical and visually appealing. This design maximises open area while retaining the structural integrity required for a wide range of industrial and architectural applications.
The small hexagonal apertures, spaced closely with a 4.5mm pitch, allow high levels of airflow and drainage while acting as a reliable barrier against larger particles, insects, or debris. This makes the mesh ideal for use in ventilation panels, air return grilles, machine guards, radiator covers, and screening systems. The hexagonal pattern is known for its efficient strength-to-weight ratio and is commonly used where stability, airflow, and appearance are all important.
Made from hot-dipped galvanised steel, the sheet is protected by a durable zinc coating, offering outstanding resistance to rust and corrosion, even in harsh or damp environments. It’s an excellent choice for exterior installations, HVAC enclosures, facade elements, and garden or workshop fittings, where long-term exposure to the elements is expected.
The 1mm thickness ensures the mesh is rigid enough for freestanding panels or structural fixings, yet still easy to work with. It can be cut, shaped, drilled, or welded using standard fabrication tools, making it highly adaptable for custom builds and installations. The fine perforation pattern also gives the sheet a modern, minimal aesthetic, ideal for design-led projects such as interior partitions, lighting screens, or acoustic panels.
