Basic Info
Beijing-style traffic guardrail, also known as inverted U-shaped or N-shaped guardrail, is a mainstream road isolation facility designed in accordance with Beijing municipal standards. It is mainly welded from inverted U-shaped round steel, upright posts and cross supports, and made of galvanized steel pipes with anti-corrosion treatment of hot-dip plastic coating or spray painting. It is widely used nationwide for road central separation, motor-non-motor vehicle separation and pedestrian isolation, featuring simple structure, good visibility, attractive appearance, high stability and durability.

Frequently Asked Questions (FAQ)
Q:How does Beijing-style barrier compare to wave beam guardrail?
A:Beijing-style barriers offer 30% higher impact resistance due to vertical column reinforcement, while wave beams provide better deflection for highway collisions. Beijing types are preferred for urban roads with speed limits below 60km/h.
Q:What maintenance does Beijing traffic barrier require?
A:Annual inspection for rust spots, bolt tightness checks every 6 months, and reflective strip replacement every 2-3 years. Hot-dip galvanized models last 10-15 years with minimal upkeep.
Q:Can Beijing barriers be customized for curved roads?
A:Yes, flexible connectors allow 15-30° bending per module. Custom arc designs require CAD drawings and factory prefabrication to maintain structural integrity (minimum radius 5m).
