Headwall Security Grates
Headwall Security Grates
Civilcast Headwall Security Grates are hot-dip galvanised steel grates that fit over a headwall or culvert outlet to restrict unauthorised access while still allowing water through. They're supplied across a standard range of sizes, including the HESG0450 at 580mm span x 350mm height for DN375/DN450 pipe, with lockable configurations available where access needs to be restricted rather than just screened. The grates suit both new headwall installations and retrofits onto culverts already in the ground, and are part of Civilcast's precast concrete range.
Features
Civilcast Headwall Security Grates are built from hot-dip galvanised steel for corrosion resistance in outdoor drainage environments, with a heavy-duty frame designed for long service life rather than periodic replacement. Standard sizing covers a range of pipe diameters, with lockable variants available for sites where unauthorised entry is a specific concern.
- Hot-dip galvanised steel for corrosion resistance
- Heavy-duty construction for long service life
- Standard range of sizes (e.g. HESG0450: 580mm span x 350mm height for DN375/DN450 pipe)
- Lockable configurations available
- Suits both new headwall installations and retrofits

Benefits
A culvert or drainage outlet left open is both a safety hazard and an access point for anyone wanting to enter the stormwater network, so fitting a security grate addresses both risks with one component rather than treating them separately. Because the grates retrofit onto an existing headwall as well as a new one, a council or contractor can upgrade an older site to current access-control expectations without replacing the headwall itself.
- Reduces public safety risk at open culvert and drainage outlets
- Restricts unauthorised access into stormwater and drainage networks
- Retrofits onto existing headwalls, avoiding a full headwall replacement
- Hot-dip galvanising keeps maintenance and replacement costs down over the asset’s life
Applications
Headwall Security Grates are used wherever a stormwater or drainage outlet is exposed to public access: embankments near footpaths or parks, culverts under roads and driveways, and drainage infrastructure on council and subdivision land. They’re typically installed as a pair with a headwall or double headwall at the same pipe outlet.
- Embankments and public parkland
- Culverts under roads and driveways
- Council and subdivision drainage networks
- Paired with headwalls or double headwalls at the pipe outlet
