Product Description

Core Functions

1. 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.
2. 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.
3. Standard Crash Height Control: Lift W beam to regulated safety height to stop vehicles sliding under the guardrail and running off road.
4. Drainage & Anti-Rust: Reserved air gap drains rainwater and sediment quickly to prevent internal steel corrosion, extend whole barrier service life.
5. Stabilize Against Ground Settlement: Buffer deformation caused by road subsidence and long-term traffic vibration, keep guardrail intact and tight for years.

8. FAQ:
9. 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.
10. 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.
