Hot-dip galvanized guardrail bolts are essential fasteners designed for securing guardrails in various applications such as highways, roads, and railways. These bolts are made with a round head and a nib or oval neck under the head, providing a strong grip and secure connection. The hot-dip galvanizing process ensures they have excellent corrosion resistance, which is crucial for outdoor use.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

Corrosion Resistance: The hot-dip galvanizing process provides a layer of zinc coating that protects the bolt from rust and corrosion, extending its lifespan.Durability: Made from materials like carbon structural steel (e.g., Q235, No. 45 steel), these bolts are built to withstand harsh weather conditions and heavy loads.Easy Installation: The round head design allows for easy installation with a wrench or an Allen key.Versatility: They can be used in a variety of applications, including construction, automotive, and machinery assembly.Safety: The hot-dip galvanized finish ensures that the bolts remain secure and functional, reducing the risk of failure in safety-critical applications.

Scope of 

Application

Highway Guardrails: Used to secure guardrail systems along highways, providing a vital safety measure for vehicle and pedestrian protection.Railway Platforms: Employed in railway stations to secure safety barriers and guardrails.Construction Sites: Utilized in temporary fencing and guardrails around construction areas.Outdoor Furniture: Ideal for adjustable outdoor furniture that needs to be leveled on uneven surfaces.Automotive Industry: Used in the assembly of vehicles where a secure and aesthetically pleasing connection is needed.
