Frequently Asked Questions About W Beam Guardrail
1.What is the difference between W beam guardrail and Thrie beam guardrail?
W beam guardrail (two-wave) is the most common type for general highways, offering reliable protection at economical cost. Thrie beam guardrail (three-wave) has a larger profile and higher strength, making it suitable for high-speed roads, heavy vehicle lanes, steep slopes, and dangerous road sections requiring enhanced impact resistance.
2.What surface treatments are available for your W beam guardrail?
We mainly provide hot-dip galvanized finish as standard, which offers excellent corrosion resistance. For areas with high humidity, coastal salt spray, or aesthetic requirements, we also offer galvanized + PVC coating, galvanized + powder coating, and customized color options to extend service life and improve appearance.
3.How long can your W beam guardrail be used outdoors?
Under normal outdoor conditions, hot-dip galvanized W beam guardrail can be used for 15 to 20 years. With additional protective coating, its service life can reach 25 to 30 years even in harsh environments such as coastal areas, rain-prone regions, or industrial zones.
4.What standards does your W beam guardrail comply with?
Our W beam guardrail is manufactured in strict accordance with international standards including AASHTO M180, EN 1317, GB/T 31439, and other regional road safety norms. Complete material test reports, quality certificates, and crash test reports can be provided to meet project inspection requirements.
5.Can you supply complete guardrail systems including accessories?
Yes, we provide one-stop full-system supply, including W beam panels, posts, spacers, end terminals, bolts, nuts, and other connecting fittings. All parts are precisely matched to ensure easy installation, stable structure, and consistent quality for the entire barrier system.
