Power transmission structures: towers & steel poles

Lattice towers, tapered steel poles (postes troncocónicos), and galvanized poles for power transmission and distribution.

Some of our partner shops specialize in structural steel for the power industry: transmission towers, tapered steel poles, and galvanized poles, built to project specifications for utilities, EPC contractors, and municipalities.

Materials & standards

Transmission and distribution structures are engineered to defined structural and corrosion-protection standards, and fabricated accordingly.

  • ASTM A572 structural steel
  • ASTM A871 weathering steel
  • ASCE 48 pole design
  • AWS D1.1 structural welding
  • ASTM A123 / ISO 1461 galvanizing

Our hot-dip galvanizing is already part of our capability — see hot-dip galvanizing for details. In Mexico, transmission structures are typically specified to CFE (Comisión Federal de Electricidad) requirements; tell us the specification your project calls for.

Who we build for

  • Electric utilities
  • EPC contractors
  • Municipalities
  • Telecommunications companies

Voltage classes from distribution up through high-voltage transmission — tell us your project's voltage class and governing standard, and we'll match it to the right partner shop.

Common questions

What is the difference between a lattice tower and a tapered steel pole (monopole)?

A lattice tower is a self-supporting structure built from angle steel members, commonly used for long-distance, high-voltage transmission lines. A tapered steel pole, or monopole (poste troncocónico), is a single tapered tubular shaft, often preferred where land is limited, such as urban and sub-transmission corridors.

Do you provide hot-dip galvanized poles and towers?

Yes. Hot-dip galvanizing per ASTM A123 and ISO 1461 is the standard corrosion protection for transmission and distribution structures, and it's a capability already in our network.

Can you build structures to CFE or utility specifications?

Tell us about the specification your project requires, including voltage class and governing standard, and we'll work with you to match it to the right partner shop.
