Why choose Guardian trench shields?
Lightweight without compromise
Complete shield setup. Small excavators can lift and position shields using inbuilt lifting points. This cuts machinery costs and makes shields accessible for restricted sites.
Built for New Zealand conditions
Aluminium doesn’t rust. In wet, muddy trench work, that longevity matters. Our shields handle New Zealand’s diverse soil types — from sandy coastal ground to heavy clay — without the corrosion issues affecting steel alternatives.
Flexible for real work
Multiple strut points mean you’re not locked into one position when services are in the way. Detachable 600mm legs keep shields off the trench bottom when pipes or cables run underneath. Adjustable struts (0.6m-3.5m) accommodate different trench widths.
Fast to deploy and move
Shields can be assembled or dismantled in minutes. Move quickly around busy sites or transport between jobs without specialised equipment.
Compliance and certification
Every Guardian shield meets or exceeds at least one of the following standards:
- New Zealand: AS 4744.1-2000
- Australia: AS 4744.1-2000
- United States: OSHA Sub Part P
- Britain & Europe: BS EN 13331.1 and 13331.2
Each shield carries an identification plate showing standards compliance. Certifications and Safe Use Manuals provided to support Health & Safety requirements and WorkSafe inspections. Reference guides on every shield show safe strut positioning.
