Product Description

Guardrail spacer block (also called blockout / offset block) is the key energy-absorbing fitting of W-beam crash barrier system, installed between guardrail beam and steel post. Available in trapezoidal, U-shape, box type and thrie-beam twin block styles, stamped from Q235 steel with full hot dip galvanization. It is an indispensable energy absorption component for road anti-collision safety.

Energy Absorption & Injury Reduction: Deform under vehicle impact to absorb crash kinetic energy, avoid rigid collision between cars and posts, effectively lower passenger injury risks.
Stress Dispersion: Create buffer gap between beam and post to evenly distribute impact force, prevent beam crack and post bending, improve overall barrier crash resistance.
Standard Crash Height Control: Lift W beam to regulated safety height to stop vehicles sliding under the guardrail and running off road.
Drainage & Anti-Rust: Reserved air gap drains rainwater and sediment quickly to prevent internal steel corrosion, extend whole barrier service life.
Stabilize Against Ground Settlement: Buffer deformation caused by road subsidence and long-term traffic vibration, keep guardrail intact and tight for years.

Application Scenarios

Highways, national roads, municipal expressways, steep riverside & cliff high-risk sections. Compatible with 2-wave, 3-wave guardrails, round pipe posts, open U/C channel posts and H steel posts.
