Structural Steel Plates for Transmission & Telecom Towers – High Strength, Lightweight, and Long Life

Transmission towers, telecom towers, and microwave antenna structures demand structural steel that balances strength, weight, and long-term durability. At Hindustan Steel Corporation, we supply precision-engineered structural steel plates that meet the unique design, wind load, and corrosion resistance needs of communication tower fabrication. Whether it’s high-voltage transmission lines, rooftop mobile towers, or large self-supporting lattice masts, our plates are trusted across India and global markets for quality and reliability.

What Are the Ideal Applications of Structural Steel in Transmission Tower Fabrication?

Our structural steel plates are used in:

  •  High-tension transmission line towers (132 kV, 220 kV, 400 kV, 765 kV)
  • Telecom towers (2G, 3G, 4G, 5G-ready antenna structures)
  • Guyed masts, monopoles, and rooftop towers
  • Broadcast and microwave communication towers
  • Relay and radar towers for defence & air traffic control
  • Railway signaling masts and remote solar-powered towers

Which Industries Use These Plates?

  • Power Transmission & Grid Infrastructure
  • Telecom Operators & Mobile Tower Contractors
  • Defence & Aerospace Communications
  • Broadcasting Companies & Radio Networks
  • Railways & Metro Authorities
  • Tower Fabricators & EPC Contractor

Mechanical Properties Required in Tower Structural Plates

Structural steel plates for tower fabrication require a combination of moderate to high yield strength, good weldability, and excellent atmospheric corrosion resistance. Typical mechanical properties include:

  • Yield Strength: 240–355 MPa (IS 2062 E250/E350, EN 10025 S355J2, ASTM A572 Gr 50)
  • Tensile Strength: 410–630 MPa
  • Elongation: ≥ 20%
  • Impact Toughness: Down to -20°C (Charpy V-notch)
  • Good cold bending and weldability without preheating

Complying with Indian & International Standards for Tower Steel Plates

We supply tower-grade steel plates as per:

  • IS 2062 Grades A, E250BR, E350, E450
  • EN 10025 S235JR / S275JR / S355J2
  • ASTM A572 Grade 50 / 60
  • JIS G3101 SS400
  • DIN St37 / St52
  • GOST St3 (for CIS market tower projects)

Plates are available with mill test certificates (MTC), IBR if needed, and with impact testing (CVN) reports for high-altitude or cold region installations.

Size Range, Thickness & Availability for Tower Fabrication

We offer a full range of plate thicknesses and formats suited for cutting tower components like bracings, base plates, gusset plates, cleats, and anchor plates:

  1. Thickness: 4 mm to 100 mm
  2. Widths: up to 2500 m
  3. Lengths: up to 12000 mm (custom cut-to-size also available)
  4. Form: Hot rolled plates, sheared or mill edge, pickled or oiled

We also support laser/plasma cutting, CNC punching, and pre-fabrication upon request.

Heat Treatment Options for High-Altitude and Corrosive Installations

For towers in coastal or extreme cold regions, we provide:

  • Normalized plates (N)
  • Low-temperature impact-tested steel
  • Corrosion-resistant steel (Corten-type)
  • Hot-dip galvanized or zinc-coated options on demand

Our plates can be pre-treated to reduce on-site welding time and improve fit-up during tower assembly.

Fabrication Benefits – Why Tower Builders Prefer Our Plates

  • Excellent weldability and dimensional tolerance
  • Compatible with automated punching and bending
  • Smooth surface finish for galvanization
  • Supports tight-tolerance laser/CNC cutting
  • Bulk supply for tower mass production or small project-specific lots

We cater to both OEMs and regional tower contractors.
