A: We primarily use high-quality Q235B or Q345B grade steel. For surface protection, we offer Hot-Dip Galvanizing (zinc coating up to 550g/m² or 600g/m²) and PVC/Powder Coating in various colors. These treatments ensure excellent corrosion resistance and a service life of over 20 years in outdoor environments.
A: Yes. We manufacture both Two-Wave (W-Beam) for standard highway safety and Three-Wave (Thrie-Beam) for high-hazard areas, sharp curves, or heavy-traffic sections. We also supply all necessary accessories, including posts, spacers, end buffers, and bolts, ensuring a complete solution for your project.
A: Absolutely. Our products comply with international standards such as AASHTO M180 (USA), EN1317 (Europe), and JT/T 281-2007 (China). We can provide test reports and mill certificates upon request to guarantee the safety and quality of your project.
A: Our highway guardrails are made from high-strength zinc-coated steel using a hot-dip galvanizing process, providing superior protection against rust and corrosion. Additionally, we offer treatments meeting ASTM D4956 for reflective properties and ASTM A307 for hardware durability, ensuring a service life of over 20 years in outdoor conditions.
A: The price depends on several factors, including the thickness of the W-Beam (typically 3mm or 4mm), the weight of the zinc coating (e.g., 600g/m² or 1100g/m²), and the specific standards required, such as ASTM A36 or AASHTO M180. Please provide your project dimensions for a detailed and competitive quotation.
A: Yes. We supply a full Anticollision Highway Guardrail System, including W-Beam safety crash barriers, C/U/Sigma posts, spacers, and ASTM A307 grade bolts and nuts. All components are hot-dip galvanized to ensure uniform quality and long-term durability.
A: Generally, standard beam thicknesses are 2.67mm, 3.0mm, or 4.0mm:2.67mm / 3.0mm: Ideal for common rural roads or low-speed highway sections.4.0mm: Recommended for heavy-duty protection, bridges, and high-speed expressway sections.
