01 DOUBLE-COLUMN SUPPORT FOR SUBSTATION ENTRIES
The H Type Steel Pole is a two-column steel structure that looks like the letter "H". Two vertical steel tubes stand side by side. A horizontal beam connects them at the top. This design is common at substation entry and exit points. It is also used for line branching towers in cities. The two columns share the load from the conductors and cross-arms. The horizontal beam adds stability. This structure is more open and visually cleaner than traditional lattice towers. City planners often prefer it for urban projects.

03 PRODUCTION EQUIPMENT
Dual Columns for Better Load Distribution
The H Type Steel Pole carries heavy conductors on both sides. The two columns balance the tension. This prevents twisting. Each column is a steel tube rolled from high-quality steel plates. We use large plate rolling machines to shape the tubes. The longitudinal seams are welded with automatic submerged arc welding. This creates a strong, smooth joint. The horizontal beam connects to both columns with full-penetration welds. These welds are critical. They carry the weight of the conductors on both sides.
04 OVERALL VIEW
Precise Column Spacing for Your Site
Every H Type Steel Pole project is different. The spacing between the two columns depends on your site and load requirements. Our engineers calculate the optimal distance. We also determine the best beam height. This ensures the structure fits your existing foundations. We design for both single-circuit and double-circuit configurations. If you have specific clearance needs, our team adjusts the design accordingly.

Galvanizing Long and Wide Components
The H Type Steel Pole has long column sections. Our hot-dip galvanizing kettle is large enough to dip these sections fully. We do not compromise by cutting and welding after galvanizing. The full dip gives complete coverage inside and out. We inspect the coating thickness on every surface. The zinc layer is uniform. It will protect the pole from rust for decades. We use the same galvanizing standard for both the columns and the beam.
06 CERTIFICATIONS
Saving Space in Dense Urban Areas
The H Type Steel Pole occupies a small footprint compared to a four-leg lattice tower. This is a major advantage in crowded cities. The two columns are enough to support the required conductors. We design the base plates to match your foundation. Our pre-welded accessories save your crew time during installation. We deliver a complete package that goes together quickly.
