Frequently Asked Questions
Q
What materials are used in the octagonal galvanized electric steel power pole?
A
The poles are manufactured using high-quality low-silicon carbon structural steel, primarily Q355B/A572 (minimum yield strength ≥355 N/mm²) or Q235B/A36 (minimum yield strength ≥235 N/mm²). Other materials such as Q460, ASTM573 GR65, GR50, SS400, SS490, and ST52 are also available to meet specific project requirements.
Q
How long does the anti-corrosion protection last on these steel poles?
A
The poles undergo a "double hot-dip galvanizing inside and out" process with a zinc layer thickness of ≥86μm (610g/㎡). This treatment provides strong adhesion and ensures a basic anti-corrosion lifespan of more than 30 years, making them highly suitable for long-term outdoor installations.
Q
What height and size options are available for these electric poles?
A
The poles are available in heights ranging from 25 FT to 45 FT (and beyond), with top diameters from 120mm and bottom diameters up to 317mm. Wall thickness ranges from 2.5mm to 3mm for standard sizes, and custom dimensions can be manufactured according to project specifications. Each section can be formed up to 14m without a slip joint.
Q
What quality certifications and inspection reports are provided with the product?
A
The production process follows ISO 9001 quality management standards. Full-process quality tracking is implemented from raw material entry to finished product delivery. Third-party authoritative weld seam inspection reports and galvanized layer thickness inspection reports are available. Welding conforms to AWS (American Welding Society) D1.1 standards.
Q
What wind and seismic conditions can these poles withstand?
A
The poles are engineered to withstand wind speeds of up to 160 Km/h (30 m/s) and are designed to resist earthquakes of grade 8 intensity. Strict mechanical calculations and finite element analyses are conducted to guarantee structural safety under extreme wind loads, ice loads, and accidental loads.
Q
What are the typical application scenarios for these octagonal steel poles?
A
These poles are ideal for permanent municipal lighting and power supply projects including urban main roads, community streets, industrial parks, parking lots, key scenic areas, and large public squares. They are also well-suited for conventional power and lighting infrastructure projects that prioritize cost-effectiveness, long-term reliability, and structural durability.
