The standard of street sign pole is mainly based on the standard: GB/T 23827-2009 road traffic sign plate and support parts at the same time also combined with the following standards comprehensive consideration: 05MR601 urban road traffic signs and routes GB 5768.1-2009 road traffic signs and marking. Sign pole column classification signal pole column generally has a single column type traffic sign pole, multi-column traffic sign pole.
Robust Modular Construction
Poles are fabricated in cylindrical, slip-flanged sections for ease of transport and field assembly. Bolted connections come with precision-drilled holes and receiving nuts for fast, error-free installation.
Vibration & Fatigue Resistance
Designed using dynamic load analysis to resist aeroelastic excitation from wind-induced vibration. Critical zones feature internal stiffeners or external vibration dampers.
Pedestrian & Vehicle Safety
Poles can be engineered for breakaway compliance under NCHRP 350 or MASH to minimize impact severity. Additionally, options are available for integrated ground-level electrical boxes or inspection doors.
CNC plasma or laser cutting ensures dimensional precision.
Submerged arc welding (SAW) and robotic welds adhere to AWS D1.1/D1.5 standards.
Non-destructive inspection methods (UT, MT, PT) applied to weld zones for guaranteed integrity.
Full material traceability: mill certificates provided for steel grade and galvanizing reports ensure verifiable quality.
Full hot-dip galvanizing to ISO 1461 ensures zinc adherence and even thickness—boasting ≥85 µm.
Salt spray resistance exceed 1,000+ hours per ASTM B117 for coastal or high-humidity environments.
Optional powder coating or fluorocarbon finish in custom RAL color codes, shielding against corrosion and UV exposure.
Street name and traffic regulatory signs
Overhead freeway lane-use signals and variable message signs
Parking lot signage, entrance portals, and road warning systems
Custom roadway and urban wayfinding installations
Temporary or permanent traffic management in construction zones
Custom engineering solutions tailored to local wind, seismic, or installation codes
In-house galvanizing and QA procedures to assure consistent corrosion resistance
