2) What coil materials and coatings are recommended for highway guardrails?
- Carbon steel coils meeting AASHTO M180 Class A/B/C or EN 10346 galvanized steels (GI, Z275–Z600); zinc–magnesium (ZM) coatings are increasingly used for improved corrosion resistance with lower coating mass.
3) How fast can modern guardrail roll forming lines run while maintaining quality?
- 25–60 m/min with inline punching; high-end lines with accumulators and servo punching can reach 70–90 m/min on standard W-beam patterns while holding ±1.0 mm length tolerance.
4) How do manufacturers ensure crashworthiness compliance of roll-formed guardrails?
- By adhering to dimensional tolerances, hole spacing, and steel mechanical properties specified in AASHTO/EN standards, and by sourcing systems that have passed full-scale crash tests (e.g., MASH or EN 1317 crash testing) for the complete roadside safety system.
5) What are the key maintenance tasks to keep throughput stable?
- Daily cleaning and visual checks; weekly lubrication of bearing blocks and guides; monthly roller alignment and pass check; semiannual hydraulic oil/filter change; annual inspection of punching dies and flying shear blades.
2025 Industry Trends
