Commonly referred to as Trench Mesh, our Maxi Mesh Trash Screens are designed for On-Site Detention (OSD) stormwater systems. Installed over orifice plates or outlet pipes, they act as a durable debris screen that prevents leaves, silt, and rubbish from entering stormwater discharge lines.
By protecting the outlet from blockage, Maxi Mesh helps maintain consistent discharge flow rates, ensuring the OSD system operates as designed during heavy rain events.
Manufactured from heavy-duty hot-dip galvanised expanded steel, these screens provide excellent corrosion resistance in wet environments such as concrete pits, stormwater tanks, and underground detention systems.
Standard industry sizes available:
These sizes are designed to suit common OSD pit configurations used across commercial and residential stormwater systems.
Hot-dip galvanised expanded steel for long-term corrosion protection in wet or submerged environments.
Forms a protective cage around the outlet or orifice plate, allowing water to flow through multiple mesh surfaces while preventing debris from blocking the discharge point.
Typically fixed directly to the pit wall or over the outlet pipe using galvanised or stainless masonry anchors.
Large mesh surface area reduces the risk of debris completely covering the outlet opening.
Helps OSD systems maintain their designed discharge capacity during heavy rainfall events.
Debris collects on the screen, where it can be easily removed during routine pit inspections.
Heavy-gauge galvanised expanded steel resists deformation, corrosion, and hydraulic pressure.
