Galvanized steel pipes with an 85μm zinc coating offer exceptional corrosion resistance, making them ideal for demanding environments and international engineering projects. Covering a diameter range from DN25 to DN200, these pipes meet global standards for durability and long-term performance.

✅ 85μm Zinc Coating: Salt Spray Test Compliance
The zinc layer thickness of 85 microns significantly enhances the pipe’s protection against corrosion. According to ISO 9227 or ASTM B117 salt spray test standards:

Red rust resistance: ≥ 480–720 hours

Ensures suitability for coastal, humid, or chemically aggressive environments

Often required for exported piping systems to Europe, the Middle East, and Southeast Asia

Such coatings are also in line with anti-corrosion class C4–C5 (per ISO 12944), commonly requested in infrastructure tenders.

✅ DN25–DN200 Range: Flexible and Standardized
The DN25–DN200 range covers the most widely used sizes in:

Building plumbing systems

Industrial water delivery

Fire protection piping (sprinkler systems)

Gas and compressed air lines

Standard dimensions make these pipes easy to integrate into international pipeline systems and modular installations.

✅ Key Application Scenarios
Pipes with 85μm zinc coating are commonly used in:

These pipes are also preferred for above-ground outdoor installations due to their enhanced lifespan and minimal maintenance.

✅ Export & Certification Readiness
To support international distribution, galvanized pipes with 85μm coating can be supplied with:

EN 10240 / ISO 1461 compliance

Mill Test Certificates (MTCs)

Third-party inspection reports (SGS, BV, TÜV)

Custom packaging for container shipment

Conclusion

Galvanized steel pipes sized DN25–DN200 with an 85μm zinc coating combine robust corrosion resistance, salt spray test compliance, and versatile application flexibility. They are a reliable, export-ready choice for global projects demanding performance in harsh environments.
