Key Features & Technical Specifications
- High-Strength Material: Made from Q235 steel, which is recognized as equivalent to ASTM A36, offering excellent weldability, formability, and tensile strength for heavy-duty impact resistance.
- Hot Dip Galvanized Finish: A thick zinc coating (average 85µm per spec) provides superior protection against rust, oxidation, and harsh weather, extending service life to 15-20 years in normal environments.
- Standardized Dimensions: 4320mm (L) x 310mm (H) x 3mm (T) – compatible with most common post spacing and mounting systems, reducing on-site modification costs.
- Wave Profile Design: The classic W-beam profile effectively absorbs and redirects impact energy, minimizing vehicle damage and occupant injury.
- Easy Installation: Pre-punched holes for bolted connections with standard guardrail posts and blocks, simplifying field assembly and reducing labor time.
- Low Maintenance: The galvanized coating requires no painting or regular upkeep, offering long-term cost savings.
