This Class 4 system delivers 30 kN impact resistance verified to AS/NZS 1170.1, with integrated mesh and handrail for enhanced pedestrian protection. Built for fast, predictable installation using standardised 2000 mm post spacing, precision base plates, and M20 anchoring, it provides long-term durability in galvanised or powder-coated finishes.
Our Class 4 guardrail system is independently crash-tested and certified to AS/NZS 1170.1:2002, delivering verified 30 kN impact performance for low to medium traffic environments. The integrated handrail and mesh provide dual-layer protection, enhancing pedestrian guidance while preventing debris intrusion and improving post-impact stability.
Impact trials demonstrated that the guardrail continues to hold its shape, absorb force, and retain vehicles or equipment during impact events. The integrated mesh and handrail were also independently validated, confirming dependable operation across varied applications—from multi-level carparks to industrial and service walkways.

Certified 30 kN Impact Performance
Independently tested to AS/NZS 1170.1, the Class 4 Kwik-Guard® system is engineered to withstand 30 kN impact loads, providing dependable protection against vehicle collisions in carparks, service areas, and industrial environments.
Integrated Handrail for Pedestrian Safety
The built-in handrail offers clear pedestrian guidance and reinforces safety on walkways, ramps, and elevated access routes, ensuring reliable performance in high-movement zones.
Dual-Barrier Protection with Mesh Infill
Lightweight mesh panels function as a secondary containment layer, improving debris control and enhancing system rigidity without adding installation complexity.
Strength Without Weight Penalty
Its engineered design delivers strong impact resistance while remaining lighter than conventional steel barrier systems, enabling faster handling, simpler transport, and reduced installation time.
With an integrated handrail and mesh infill, the system provides two layers of protection, guiding pedestrian movement while preventing debris, small objects, or equipment from entering hazardous zones. This reduces slip, trip, and debris-related incidents across busy sites.
The mesh and post-yielding design help the guardrail absorb force and maintain structural shape, reducing the likelihood of collapse or secondary hazards after a collision. This ensures safer conditions during and after impact events.
The built-in handrail delivers a clear, defined path—improving pedestrian control in carparks, walkways, service corridors, and industrial environments. This reduces confusion, supports compliant movement, and lowers the risk of pedestrian-vehicle conflict.
Engineered for diverse environments, including outdoor carparks, warehouses, industrial facilities, perimeter zones, service areas, and shopping centre carparks, the system adapts to site-specific requirements without compromising safety or performance.
Posts are designed for 2000 mm maximum centre-to-centre spacing, with 130 × 240 × 15 mm base plates anchored using M20 × 160 mm through-bolts. This allows predictable installation, modular configuration, and flexible layouts tailored to any project.
Constructed from galvanised steel (AS 4680) or yellow powder-coated finishes, the system balances robustness with lightweight transport. Mesh panels provide a secondary barrier, enhancing impact absorption while simplifying handling and installation.
Designed for sites exposed to regular vehicle movement, the Class 4 Kwik-Guard® system is suitable for carparks, warehouses, freight facilities, perimeter roads, plant rooms, and service corridors. Its AS/NZS 1170.1-certified 30 kN rating, combined with mesh infill and a full-height handrail, provides dependable protection for pedestrians and infrastructure. Lightweight construction and standardised mounting components ensure fast installation on a wide range of substrates.
Mesh and handrail guardrails deliver impact-tested strength and debris protection for multi-level carparks.
Upgrade safety with mesh guardrails that absorb impact, meet 30kN compliance, and enhance pedestrian protection.
Crash-tested guardrails with mesh infill protect staff and equipment, keeping service areas secure and compliant.
Durable guardrails with mesh and handrail integration safeguard shoppers and assets while maintaining visual appeal.
Reliable 30kN guardrails with mesh panels reduce accident risks and keep high-traffic commuter spaces protected.
