Project Overview
■Project Date: October 2017
■Project Name: Oilfield Road Surveillance and Security Project
■Application: Video surveillance coverage for oilfield production roads
■Deployment: 16 CCTV pole assemblies, each with a 6.8 m upright and a 25 m cantilever arm
■Delivery Lead Time: 16 days
This project supported road surveillance and security infrastructure in the Huabei Oilfield production area.
To accommodate wide roads and extensive surveillance requirements, we supplied integrated CCTV pole assemblies with long-span cantilever arms. Each 25 m arm extended across the road to position surveillance equipment, providing wider video coverage from a single pole location.
Project photographs document factory prefabrication, structural reinforcement fabrication, and on-site lifting and installation. Together, they demonstrate our integrated capabilities in structural design, manufacturing, and site delivery.
The 25 m arm forms a long-span cantilever structure subject to greater wind loads and bending moments than conventional CCTV poles.
Key design considerations included:
—Cantilever arm strength
—Overall pole stability
—Stability of equipment mounted at the arm tip
Pole base reinforcement and an optimized arm design improved overturning resistance to support long-term operation in exposed oilfield locations.
The poles operate outdoors under conditions that include:
—Saline and alkaline soils
—Temperature fluctuations
—Exposure associated with oil and gas operations
Conventional protective treatments may be insufficient for long-term service. The poles therefore required durable weather and corrosion protection to reduce maintenance frequency.
Oilfield production roads carry daily transport traffic, leaving limited windows for installation.
The project required:
—Minimal on-site fabrication
—Shorter road closure periods
—Rapid lifting and installation
Factory prefabrication was essential to enable efficient on-site assembly.
The 16 extra-long cantilever CCTV pole assemblies were custom-engineered products requiring coordinated:
—Material procurement
—Structural fabrication
—Welding
—Corrosion protection
Completing production and delivery within 16 days required tight coordination of manufacturing and scheduling.
The pole structures were manufactured from Q355B high-strength structural steel.
For the 25 m cantilever arms, structural calculations were completed using local design wind pressure:
◎Tapered, variable-section arms: Limited cantilever tip deflection to ≤ L/150 (≤ 167 mm), reducing wind-induced camera vibration.
◎Reinforced bases: Thicker base plates and multiple triangular stiffeners reduced rotation at the pole base and increased overturning resistance.
◎Finite element analysis: Verified stress and deformation under wind loading to support stable long-term equipment operation.

The structures were hot-dip galvanized with a zinc coating thickness of ≥ 85 μm.
The treatment provided:
◎Zinc protection for both internal and external surfaces
◎Resistance to combined exposure to saline, alkaline, and oilfield contaminants
◎Reduced outdoor corrosion risk and maintenance requirements
The corrosion protection system was selected for long-term service on oilfield roads.
All primary structural components were fabricated in advance, including:
◎Pole shafts
◎Cantilever arms
◎Reinforcement components
◎Flanged connection components
On-site work was limited to lifting, positioning, and securing the assemblies, improving installation efficiency and reducing disruption to oilfield road operations.
A dedicated production schedule was established to meet the project deadline.
The following activities were coordinated across production batches:
◎Steel fabrication
◎Welding
◎Corrosion protection
◎Final inspection
All 16 extra-long cantilever CCTV pole assemblies were delivered within 16 days.
Project Results
All 16 CCTV pole assemblies, each comprising a 6.8 m upright and a 25 m cantilever arm, were installed.
The project delivered:
→Wide-area video surveillance coverage for oilfield roads
→Across-road equipment mounting from a single pole
→Reduced need for multiple pole locations
The long-span cantilever structure and reinforced pole design improved equipment mounting stability in demanding outdoor conditions.
Delivery was completed as scheduled, providing a reliable pole solution for surveillance applications in oilfields and other energy infrastructure sites.
This project demonstrates our engineering and delivery capabilities for large custom CCTV poles and specialized pole structures, including:
▲Long-span cantilever CCTV pole design
▲High-strength steel fabrication
▲Corrosion protection systems for industrial environments
▲Rapid production and delivery of custom pole structures
We provide custom CCTV pole solutions for oil and gas fields, pipeline infrastructure, mining sites, and industrial parks requiring wide-area video surveillance.
