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.
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)?
