Hot-dip Galvanized Bolts Introduction
Hot-dip galvanized bolts are widely used in power facilities, construction industry, petrochemical industry, machinery manufacturing, transportation facilities and other fields.
The hot-dip galvanizing process refers to the method of immersing fasteners in a zinc solution at 450~560°C to form a layer of zinc coating on the surface of the fasteners.
The thickness of the zinc layer is generally 30-100 microns. The galvanized layer of hot-dip galvanized bolt has good anti-corrosion effect, good hardness, strong adhesion, and is not easy to fall off.

Product FAQs
Hot-dip galvanized bolts have the advantages of corrosion resistance, wear resistance and high strength. Here are some of its common uses:
1. Construction industry: Hot-dip galvanized bolts are often used in building structures, such as connecting steel structures, beams, columns, etc. Hot-dip galvanized bolts enhance the structural stability and durability of your building by providing reliable connections and long-term resistance to corrosion in outdoor environments.
2. Outdoor facilities and landscaping: In outdoor environments, metal components are susceptible to atmospheric moisture, rain and other natural elements. Therefore, Hot-dip galvanized bolts are often used in various outdoor facilities such as landscaping, outdoor furniture, fences, doors and windows to extend their service life.
3. Bridge and road engineering: In bridge and road engineering, Hot-dip galvanized bolts are used to connect various components, such as bridge beam sections, guardrails, road signs, etc. Hot-dip galvanized bolts are able to withstand high strength and critical loads while resisting corrosion and damage from the environment.
4. Marine and coastal engineering: Due to the large amount of salt in seawater and the humid environment, metal components are susceptible to corrosion. Hot-dip galvanized bolts are widely used in marine and coastal engineering to join structures such as piers, offshore platforms, ships and breakwaters to provide additional protection against corrosion.
Hot-dip galvanized bolts play an important role in many fields, and their corrosion resistance and high strength make them an indispensable component in many engineering projects.

Hot-dip galvanized bolts are usually made of carbon steel or alloy steel, both of which have good mechanical properties and corrosion resistance and are well suited for galvanizing. Common specifications include:
Diameter: Usually measured in inches or millimeters. Common diameters range from 1/4 inch to 1 inch (6mm to 25mm), and bolts for different uses may have different diameters.
Length: Length is usually measured in inches or millimeters (mm). The length depends on the specific use and installation requirements of the hot-dip galvanized bolts and can be customized as needed.
Thread Specification: The thread specification of hot-dip galvanized bolts is usually measured in inches or millimeters (mm). Common thread specifications include UNC (Unified National Coarse), UNF (Unified National Fine), Metric, etc.
Strength grade (Grade): The strength grade of hot-dip galvanized bolts varies according to their materials and manufacturing processes. Common strength levels include 8.8, 10.9, 12.9, etc.
Head Type: Common head types of hot-dip galvanized bolts include Hex Head, Round Head, Flat Head, etc. Choose the appropriate head type according to the specific use.
The specifications and material selection of hot-dip galvanized bolts depend on their specific use and installation environment. When selecting hot-dip galvanized bolts, factors such as load requirements, environmental conditions, installation methods, etc. need to be considered to ensure that the selected hot-dip galvanized bolts can meet the needs of the project.
