Are you a manufacturing factory or a trading company?

Xintong is a manufacturer. Founded in 1999, we operate a 100,000 m² production base in Gaoyou, Jiangsu, China, with 7 production lines covering steel pole forming, welding, hot-dip galvanizing, powder coating and LED / solar lighting assembly. Buyers are welcome to audit the factory on site or by live video.

Which markets do you serve, and which standards and certifications do you work to?

Our products are installed in 80+ countries, including Central Asia, the Middle East, Africa, Southeast Asia and South America. We manufacture to EN, ASTM and AASHTO specifications under ISO-based quality management, and supply material certificates, galvanizing reports and test records with each shipment.

Do you only sell individual products, or do you provide complete solutions?

We provide both. Beyond supplying poles and luminaires, our engineers prepare CAD structural drawings, 3D renderings and DIALux lighting simulations, then support installation remotely or on site. Warranty coverage is available for up to 10 years depending on the product.

What information do you need to prepare an accurate technical proposal?

Please share the application and road width, required mounting height, illumination standard or target lux, local design wind speed, power supply type (grid or solar), required autonomy days for solar systems, quantity, delivery port and any tender specification documents.

How do you protect steel poles against corrosion?

Poles are fabricated from Q235 or Q355 structural steel and hot-dip galvanized after welding, with optional polyester powder coating. This system is designed for a service life of 25+ years in typical outdoor environments.

Industrial Cluster Superiority

Factory Direct Scale: Gaoyou's Manufacturing Ecosystem

Why Yangzhou Xintong Traffic Equipment Group delivers unprecedented cost-to-performance metrics, structural precision, and lead-time guarantees for global infrastructure tenders.

The manufacturing cluster located in Gaoyou, Jiangsu Province, represents the epicenter of the global outdoor lighting and structural steel pole production network. Operating within this world-class specialized hub allows Xintong to vertically consolidate raw metallurgical procurement, robotic CNC folding, precision longitudinal welding, and chemical surface stabilization without intermediary subcontracting markups.

Founded in 1999, Xintong has grown into a 100,000 square meter intelligent manufacturing facility housing 7 automated continuous production lines. By controlling every stage from raw Q235B/Q355B coil decoiling to CNC plasma burning and final automated submerged-arc welding, we preserve absolute structural integrity.

The Gaoyou Supply Chain Efficiency Advantage

Global EPC contractors choose direct Chinese factory integration for three strategic reasons:

30-40% Faster Production Cycles: Raw hot-rolled steel coil is sourced directly from tier-1 Chinese mills (Baosteel, Shagang), eliminating raw-material transit lag.
Complete Turnkey Solutions: Mechanical masts, electrical internal harnesses, smart IoT control cabinets, and optical fixtures arrive pre-engineered and factory pre-assembled.
Optimized Ocean Freight Logistics: Segmented modular slip-joint designs allow high mast sections (up to 50m) to telescope nested within standard 40ft High Cube containers.

Procurement Guidelines

Global EPC Procurement Checklist & Tender Verification

Essential quality checkpoints required by project engineers prior to final commercial commitment.

1. Metallurgical Verification

Demand EN 10204 Type 3.1 inspection certificates proving low silicon content (Si < 0.03% or between 0.15% - 0.25% Sandelin curve) to prevent brittle, over-thick galvanizing alloy phases.

2. Full Penetration Welds

Base plate to mast shaft transitions must have 100% radiographic or ultrasonic testing (UT) verified welds to prevent catastrophic cyclic fatigue failure under harmonic wind resonance.

3. Winch & Raising Mechanism

Verify stainless steel wire ropes (AISI 316), redundant dual-cable load sharing, worm-gear auto-locking brakes, and automatic mechanical latching barrels to relieve cable strain when raised.

4. Foundation Engineering

Anchor bolts must utilize high-tensile Grade 8.8 structural steel. Request matched foundation templates, civil cage drawings, and concrete compression strength recommendations based on site soil geotechnical data.

5. Complete DIALux Lighting Design

Verify compliant point-by-point ground illuminance (Eav, Emin, U0, Ul) alongside glare ratings (GR < 50) using real IES photometric files directly measured in an ISO 17025 accredited goniophotometer darkroom.

6. Hot-Dip Galvanizing Protocol

Confirm full chemical immersion complying with ASTM A123 or ISO 1461, guaranteeing an average coating thickness of 86µm to 120µm, backed by magnetic pull-off thickness test documentation.

Engineering Questions & Technical Solutions (FAQ)

Comprehensive answers addressing real-world queries raised by international contractors, structural engineers, and tender committees.

How are high mast poles segmented and assembled on-site?

High mast structures exceeding 12 meters are fabricated into tapered polygonal telescoping sections. They are joined on-site using standard hydraulic slip-joint friction fits (slip-joint method). The minimum overlap length is calculated as 1.5 times the female section's inside diameter, eliminating on-site field welding and protecting the factory hot-dip galvanized coating.

What safety mechanisms prevent the luminaire ring from falling?

Xintong raising and lowering systems employ three independent fail-safe layers: 1) A heavy-duty bi-directional self-locking worm-gear winch; 2) Mechanical latching mechanisms at the mast head that engage steel docking pins, transferring 100% of the ring load off the hoisting cables; and 3) A secondary safety hook system to protect maintenance operators at ground level.

How does Xintong engineer high masts for typhoon and seismic zones?

Our structural design team uses finite element analysis (FEA) based on localized wind maps. For high-risk areas like the Philippines, Vietnam, or Florida, masts are configured with 16 to 20 faceted polygonal geometry, thicker base plates (up to 50mm), Q355B high-tensile steel, and aerodynamic wind dampeners engineered to resist wind speeds over 60 m/s (216 km/h).

Can you provide customized tender submittal packages and DIALux designs?

Yes. We support overseas EPC contractors with comprehensive tender submittals, including stamped structural calculations, foundation concrete reaction load data, 3D CAD anchor bolt layouts, mill test reports, galvanizing thickness certificates, and point-by-point DIALux 3D lighting simulation files meeting standard municipal specifications.
