Strict verification for tensile strength, elongation, and structural integrity during dynamic vehicle impact.
Frequently Asked Questions (FAQs)
The primary distinction lies in nominal steel thickness. Class A guardrails feature a nominal thickness of 2.67 mm (12-gauge, minimum 2.55 mm), making them the standard choice for general highways and arterials. Class B guardrails feature a heavier 3.43 mm thickness (10-gauge, minimum 3.28 mm), designed for high-risk zones, steep grades, and heavy commercial freight corridors.
Under standard rural or inland highway environments, a standard 550 g/m² (80 μm) galvanized layer provides 25 to 30 years of maintenance-free service. For coastal, industrial, or high-humidity tropical zones, we recommend heavy-galvanized coatings (≥1100 g/m² or powder-coated dual layers) to withstand continuous salt spray and chemical corrosion.
Yes. We provide precision factory-curved guardrail beams (both concave and convex radii from 1.5 m to 45 m) tailored to your engineering road drawings, eliminating dangerous on-site cutting and bending.
Standard W-beams are bundled into compact, strapped packs of 50 or 100 pieces using steel belts and wood runners to avoid zinc friction damage during sea transit. A standard 20-foot container (FCL) accommodates approximately 18 to 22 tons (approx. 900–1,100 pieces of 2.67 mm beams plus hardware).
