100mm x 39mm Raised Aluminium Heavy Duty Expanded Metal Sheet | 4mm Thick

Description

100mm x 39mm Raised Aluminium Heavy Duty Expanded Metal Sheet

This 100mm x 39mm x 4mm expanded metal mesh is a heavy-duty, practical sheet material suitable for customers who need strength, rigidity and long-lasting performance in general-use applications. Made by slitting and stretching a solid metal sheet, this mesh forms a single-piece structure with no welds, giving it excellent durability and resistance to impact, bending and fatigue. The large diamond-shaped openings provide a strong and open pattern that is useful across a wide variety of non-architectural tasks.

The mesh has a long-way pitch of 100mm and short-way pitch of 39mm, producing an open and easy-to-work-with profile. With a visual open area of 40% and an airflow open area of 64%, this mesh is ideal for jobs that require a strong barrier while still allowing air, light or water to pass through. Common uses include machinery guarding, agricultural equipment repairs, screening, animal enclosures, compost bays, protective covers, DIY builds, gates, fences and workshop projects.

At 4mm material thickness, this is the heaviest and strongest version available in this pattern. In aluminium it weighs approximately 7.5 kg/m², making it easier to handle for general jobs while still offering excellent rigidity. The mild steel option weighs around 21.7 kg/m², providing a substantially stronger material suited to high-wear, high-load environments. Mild steel sheets can also be painted, primed or finished as needed for outdoor use.

This expanded metal mesh can be cut using angle grinders, power cutters or heavy-duty tin snips depending on the material chosen and the user’s tools. It can also be drilled, bolted, welded or fixed to timber or metal frames, making it a versatile option for workshops, tradespeople and DIY users. The coarse opening size ensures that the mesh is not easily clogged by debris, making it suitable for livestock-related setups, ventilation, tool storage racks and screening where visibility is still required.

FAQs For This Product

What Tools Do I Need To Cut 4mm Expanded Metal Mesh?

Cutting this heavy-duty mesh requires strong tools due to its 4mm thickness. For aluminium sheets, an angle grinder, circular saw with a metal-cutting blade, or heavy-duty tin snips may be suitable depending on your setup. For mild steel, we recommend an angle grinder or powered metal-cutting saw for clean and controlled cuts. Always wear appropriate safety equipment, as expanded metal can have sharp edges when cut. We would cut this on our specialist aluminium wall saw.

What Is This Mesh Commonly Used For?

This mesh is ideal for non-architectural, practical applications where strength and rigidity are required. Typical uses include machinery guards, tool storage cages, agricultural repairs, dog runs, security panels, ventilation covers, compost bays, screening, and general workshop fabrication. The large 100mm x 39mm diamond openings offer good visibility and airflow while still providing a strong physical barrier.

Can This Mesh Be Welded Or Fixed To Frames?

Yes. Both aluminium and mild steel versions can be fixed to frames using screws, bolts, rivets or clamps. Mild steel can be welded directly to steel frameworks, making it useful for fabrication jobs and permanent fixtures. Aluminium can be welded using specialist aluminium welding equipment or simply bolted to a wooden or metal frame for lighter-duty applications. The mesh’s single-piece expanded design ensures secure attachment without weak points.
