Hot Dip Galvanized Fasteners

 

At Petrotube, we specialize in hot dip galvanized fasteners, providing long-lasting corrosion resistance, durability, and superior performance for industrial applications. Our high-quality galvanizing process ensures excellent adhesion and protection, making our fasteners ideal for

oil & gas, marine, and offshore industries.

 

Hot dip galvanizing is a process of coating steel fasteners with a protective zinc layer to prevent corrosion.

 

This involves:

✔ Chemical Cleaning – The steel fasteners are cleaned to remove rust, oil, and surface scales for proper adhesion.

✔ Molten Zinc Bath – Fasteners are immersed in a 460°C hot molten zinc bath, ensuring complete coverage.

✔ Quenching & Cooling – After coating, the fasteners are cooled, allowing the zinc to metallurgically bond with the steel surface.

 

High-tensile fasteners such as B7/2H, Grade 8.8, 10.9, and 12.9 are commonly hot-dip galvanized for enhanced protection in demanding environments.

 

 

✔ Cost-Effective Coating – Provides long-term protection at a low cost.

✔ Extended Durability – Offers a longer lifespan compared to other coatings.

✔ High Reliability – Zinc coating ensures superior resistance against corrosion and environmental damage.

✔ Quick Application – Efficient coating process for fast production turnaround.

✔ Exceptional Toughness – Withstands abrasion, moisture, and harsh industrial conditions.

✔ Complete Surface Protection – Provides uniform coverage, even in threaded areas.

✔ Easy Inspection – Hot dip galvanized coatings are visually identifiable, simplifying quality checks.
