C Post Channel
Structural Steel Support for Guardrails and Fencing Applications
The C Post Channel is a cold-formed steel section designed primarily for use as a vertical support in crash barrier systems, fencing, and other structural applications. It plays a critical role in anchoring 2-wave and 3-wave crash barriers to the ground, ensuring the overall stability and impact resistance of the barrier system.
Manufactured from high-strength hot-dip galvanized steel, the C Post Channel offers excellent durability, weather resistance, and corrosion protection — making it ideal for long-term outdoor installations along highways, expressways, and industrial perimeters.
The channel’s C-shaped design provides a perfect balance of strength, load-bearing capacity, and ease of installation. It is available in various lengths, thicknesses, hole patterns, and surface finishes, depending on project requirements and local road safety standards (MORTH / AASHTO / EN 1317).
Key Features:
Made from high-tensile galvanized steel for enhanced strength and corrosion resistance
C-shaped profile offers excellent structural support and easy installation
Compatible with both 2-wave and 3-wave crash barrier systems
Pre-punched holes for quick assembly and alignment with guardrails
Available in customized sizes, lengths, and surface coatings
Designed to meet national and international safety standards
Applications:
Vertical posts for crash barrier systems
Fencing support in highways, airports, and industrial zones
Structural framework for temporary or permanent road safety solutions
The C Post Channel is a critical component in road safety infrastructure, providing reliable anchoring, superior structural strength, and long-term performance under harsh environmental and operational conditions.
