UNISAFE SM 3W 1.33 – H2 vehicle restraint system for engineering structures

🛡️ UNISAFE SM 3W 1.33 BW – H2 restraint system for engineering structures

UNISAFE SM 3W 1.33 BW is a single-row restraint system with plate supports, developed by UNIPROMET and distributed in France by SOLOSAR. CE certified according to EN 1317, it is specially designed for installation on engineering structures (bridges, viaducts, concrete stringers), offering a high level of safety with a triple wave profile.

🔧 Technical characteristics:

• Retention level: H2 (EN 1317-2)
• Operating width: W2 = 0.8 m
• Dynamic deflection: 0.6 m
• Vehicle intrusion: VI4 = 1.1 m
• Severity Index (ASI): B
• Type of rails: Triple wave
• Length of rails: 4.00 m
• Device width: 0.335 m
• Device height: 0.950 m
• Centre-to-centre distance between supports: 1.33 m
• Installation type: Supports on base plate, mechanical or chemical anchoring (250 mm)
• Test length: 48 m
• Material: Hot-dip galvanised steel in accordance with EN ISO 1461

✅ Advantages of the device:

• Designed specifically for engineering structures
• Very low Dn and W values for narrow structures
• Triple wave profile ensuring high impact resistance
• Plate installation suitable for concrete stringers
• Thanks to chemical anchoring, the integrity of the stringer or bridge deck is fully respected
• High level of H2 restraint validated by crash tests (TB11 and TB51)
• Durability thanks to hot-dip galvanisation

📄 Applications:

UNISAFE SM 3W 1.33 BW is recommended for:

• Bridges and viaducts
• Concrete girders
• Engineering structures requiring a compact and reliable H2 restraint system
