Guardrail integrity relies directly on its hardware connection points. Our bolts, nuts, and washers undergo rigorous yield and shear testing, ensuring zero structural failure during high-speed vehicle impacts.
Engineered for harsh coastal climates in Southeast Asia and extreme desert heat/saline environments across Saudi Arabia and the UAE. Custom zinc coating up to 1100 g/m² with uniform thread clearance.
Pre-punched and precision-drilled slots guarantee quick assembly with C-Post, U-Post, H-Post, Sigma Post, and Round Post configurations, reducing installation labor costs on-site.
Hardware items are packaged in reinforced export-grade woven bags, steel drums, or seaworthy pallets labeled per bill of quantities (BOQ) for direct delivery to construction zones.
