Rail Electrification Masts

The high-strength-to-weight ratio of prestressed concrete electrification masts sets them apart from poles made of other materials. Fully prestressed masts are produced using 60MPa concrete.

The rectangular taper of Aveng Infraset’s concrete masts and an I-Section design results in an aesthetically pleasing light-grey pole. Concrete masts are corrosion resistant and enjoy an internationally proven reputation for maintenance-free performance.

Prestressed concrete masts are manufactured with guaranteed design strengths which comply with client specifications.

The advantages of Aveng Infraset’s electrification masts are:

  • Durable 60MPa low permeability concrete
  • Fully prestressed
  • Weight-saving, I-section design
  • Maintenance-free
  • Aesthetically pleasing
  • Free-standing masts to specifications
  • Cast-in earthing bar with 12mm sockets (optional)
