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.

Complete product range: trapezoidal, U-type, box and twin blocks for three-wave barrier are all available.
Fully customizable in thickness, dimension, zinc coating and shape per client CAD drawings.
Negotiable price and lead time, factory certified with ISO three management systems, official inspection reports supplied for overseas bidding projects.
FAQ:
Q1: What is guardrail spacer block (blockout) used for?
A: It is mounted between W beam guardrail and post to absorb collision energy, disperse impact stress and prevent vehicles from sliding under the barrier.
Q2: Do your spacer blocks fit both 2-wave and 3-wave guardrails?
A: Yes, we supply regular blocks for two-wave barrier and special twin blockouts for three-wave thrie beam guardrail.
Q3: What surface anti-rust treatment do you adopt?
A: Standard full hot dip galvanization, zinc coating thickness 60–120μm can be customized for coastal anti-corrosion requirements.
Q4: Can I customize the size, thickness and shape of offset blocks?
A: FUll customization is supported, we produce according to your road standard drawings and project load demands.
Q5: Are prices and delivery lead time negotiable?
A: Unit price and production schedule are negotiable based on your total order quantity.
Q6: Do you have export certification for international highway projects?
A: Our factory holds ISO9001, ISO14001, ISO45001 three-in-one system certifications, test reports can be provided.
Q7: How do you pack spacer blocks for long ocean transportation?
A: Bundled by steel strips with anti-scratch plastic film wrapped outside to protect galvanized layer from damage and moisture rust.
