Hot-dip galvanizing (HDG) is one of the oldest and most commenly used method of protecting steel fasteners from corrosion. HDG coating is relatively maintainence-free and provides excellent corrosion protection to steel structures for 50-70 years in most atmospheric environments (industrial, urban, marine & rural).

Basic Information

Normal Sizes:M6-M20

Material: Carbon Steel(C1022A)

Surface Treatment:Hot-dip Galvanizing

Brief Introduction

Hot-dip galvanizing is a process where bolts are immersed in molten zinc to provide corrosion resistance. This coating forms a metallurgical bond with the steel, creating a protective layer that helps prevent rust and corrosion. Hot-dip galvanized bolts are commonly used in outdoor and corrosive environments, such as construction, marine, and infrastructure projects, to enhance their durability and longevity.

Functions

Hot-dip galvanizing bolts serve several crucial functions:

Corrosion Resistance: The primary purpose is to protect the bolt from corrosion and rust, especially in harsh and corrosive environments.

Longevity: The galvanized coating enhances the lifespan of the bolt by providing a durable barrier against environmental elements.

Cost-Effective: Galvanized bolts can be a cost-effective solution over time due to reduced maintenance and replacement needs.

Reliability in Outdoor Environments: Ideal for outdoor applications, such as construction and infrastructure projects, where exposure to weather elements is significant.

Ease of Inspection: The galvanized coating provides a visible and easily inspectable layer, making it simple to assess the condition of the bolt.

Aesthetic Appeal: The coating can provide a uniform and aesthetically pleasing appearance, which is advantageous in visible applications.

Self-Healing Properties: If the coating is scratched or damaged, the zinc in the surrounding areas can sacrifice itself to protect the exposed steel, exhibiting self-healing properties.
