Product Description

Types of Galvanization

Galvanized hex bolts are coated with zinc through two primary methods:

Hot-Dip Galvanizing (HDG)

The bolt is immersed in molten zinc (≈450°C), forming a thick, robust zinc-iron alloy layer
Provides superior corrosion resistance (up to 50+ years in mild environments)
Ideal for outdoor or marine applications
Thicker coating (50–150 μm) but may have a slightly rough surface

Electro-Galvanizing (Electroplating)

Zinc is deposited via electrolysis, creating a thin, smooth coating (5–25 μm)
Offers moderate corrosion protection, suitable for indoor or dry environments
Maintains precise thread dimensions due to thinner coating

Key Applications

Galvanized hex bolts are essential in industries exposed to moisture, chemicals, or weather:

Construction & Infrastructure: Structural steel connections (beams, bridges, towers), roofing, HVAC systems, and outdoor fixtures
Automotive & Transportation: Chassis components, trailers, and marine equipment
Energy & Utilities: Power line towers, wind turbines, and solar panel mounts
Agriculture & Marine: Farm machinery, irrigation systems, and boat fittings
General Manufacturing: Machinery assembly, pipelines, and industrial equipment
