High-Frequency Welded Galvanized Steel Pipe

Industry Challenges – What Buyers Really Care About

High-frequency welded galvanized steel pipes are widely used in:

Construction scaffolding, structural framework, photovoltaic support systems

HVAC pipelines, fire protection systems, industrial fluid transport

Petrochemical pipelines and anti-corrosion pressure pipes

After high-frequency welding, the weld seam becomes the most vulnerable area to corrosion. Pipe manufacturers need a reliable zinc coating or alloy spray solution to ensure long-term protection and meet export-level quality standards.

 

Key Concerns of Pipe Manufacturers & Buyers:

Will the weld seam rust again after installation or shipment?

Can the zinc layer thickness remain consistent and within inspection standards?​​​​​​​

Does the coating have high adhesion without peeling or discoloration?​​​​​​​

Is the zinc wire compatible with existing HF welding and spray coating lines?

Can the supplier provide high-purity materials with SGS / RoHS certification?​​​​​​​

Is stable mass production possible for high-output pipe factories (30,000+ tons/year)?

​​​​​​​
