1. Hot-dip Galvanized Guardrail<\/strong><\/p>\n\n\n\n

It is the most recognized and universal standard for global highway projects. The zinc layer forms a metallurgical bond with the steel surface, providing excellent salt spray resistance, UV resistance and long service life. It is suitable for coastal, mountain, desert and high-traffic road sections. No frequent maintenance is required.<\/p>\n\n\n\n

2. Galvanized + Powder Coated Guardrail<\/strong><\/p>\n\n\n\n

With colorful and smooth surface, powder-coated guardrails are widely used in urban roads, landscape highways and scenic routes. Custom colors including green, gray, blue and white are available. It provides double anti-corrosion protection and beautiful road appearance.<\/p>\n\n\n\n
