28FT Direct Buried Galvanized Electric Steel Pole with 400KGF Design Load for Power Distribution

Yixing Hongxin Illumination Facilities Co., Ltd. offers the 28FT direct buried octagonal galvanized steel electric pole, rated at 400KGF design load for medium-voltage distribution networks. This pole features an embedded direct-buried installation design that eliminates the need for cast-in-place concrete foundations, significantly reducing total installed cost and accelerating project timelines for utility contractors.

The octagonal profile provides inherent torsional stability against wind-induced twisting, while the hot-dip galvanized coating per ISO 1461 ensures comprehensive corrosion protection suitable for tropical, coastal, and high-rainfall environments. Manufactured from Q345B structural steel with full material traceability, this pole is supported by Hongxin's 25+ years of specialized production experience and a vertically integrated manufacturing process covering steel forming, welding, galvanizing, and quality inspection under one roof.

• Direct Buried Installation: Eliminates concrete foundation costs and curing time. The embedded section receives an additional bituminous anti-corrosion coating, extending service life in aggressive soil conditions including acidic, saline, and high-moisture terrains.
• 400KGF Rated Load: Designed and tested to support overhead medium-voltage distribution lines with adequate safety margins for wind, ice, and conductor tension loads, conforming to international utility design standards.
• Octagonal Tapered Geometry: The progressive diameter reduction from base to tip optimizes structural efficiency, placing more material where bending moments are greatest while minimizing weight at the upper sections for easier handling and erection.
• Pre-Drilled Hardware Points: All cross-arm, insulator, and equipment mounting holes are precisely drilled at the factory using CNC machining centers, eliminating field drilling and ensuring compatibility with standard utility hardware brackets.
• Q345B High-Strength Steel: Low-alloy structural steel with minimum yield strength of 345 MPa, providing an excellent balance of strength, weldability, and cost-effectiveness for utility pole applications worldwide.
• ISO 1461 Galvanization: Complete immersion in 450°C molten zinc produces a durable, metallurgically bonded coating with minimum 85μm thickness, delivering decades of maintenance-free corrosion protection.

The 28FT direct buried galvanized steel pole is engineered for 11KV and 15KV medium-voltage distribution lines in urban, suburban, and rural environments. Its direct-buried design is particularly advantageous in regions where concrete supply logistics are challenging, such as remote rural electrification projects, island power grids, and mountainous terrain.

The pole is also suitable for street lighting circuits, telecommunications infrastructure co-location, and small commercial transformer stations. It meets utility standards across Southeast Asia, Africa, the Middle East, and South America, and can be customized to comply with specific national regulatory requirements including NEA (Philippines), PLN (Indonesia), and EVN (Vietnam) specifications.

Poles are protected with industrial-grade film wrapping and secured in steel-framed export crates designed for ocean container transport. Each order includes complete quality documentation: Q345B mill test certificates, hot-dip galvanization thickness reports per ISO 1461, weld inspection records, and dimensional verification reports.

Third-party inspection by SGS, Bureau Veritas, or client-nominated agencies is welcomed at any production stage. Hongxin provides a standard 12-month manufacturing warranty with extended coverage options for volume contracts. Minimum order quantity is 10 pieces, with delivery within 25-35 days from order confirmation depending on quantity and customization requirements.
