Hengrui Fastener Products for Highway and Bridge Industry

Shanghai Hengrui manufactures high-strength fasteners for highway guardrails, bridges, tunnels, and structural joints. Our products include guardrail bolts, flange bolts, anchor bolts, and heavy hex nuts for bridge decks and steel connections.

We use carbon steel and alloy steel with hot-dip galvanizing or zinc-nickel coatings for long-term corrosion resistance. Fasteners are available in grades 8.8, 10.9, and 12.9 to meet structural requirements. All production follows ISO 9001:2015 standards for consistent quality and reliable delivery.
