Introduction:
The galvanized square and rectangle steel pipe has stronger protection and higher resistance to corrosion. With a protective screen on the steel pipe, it prevents the penetrating of corrosion factors effectively.
Applications:
Mainly used in curtain wall, construction, machine facture, iron-steel construction project, ship building, steel support of solar power generation, steel construction project, power engineering, electricity generating station, agricultural and chemical machinery, glass block screen wall, automobile chassis, airport, etc.
Fabrication Process
black pipe examination → acid washing → water washing→ solventcoating→ lining → drying → passivation → examination → water cooling → inside blasting → outside blasting → galvanizing → proceed cleaning → drying → printing → sprinkling passivation → packing → final examination storage
Main Components:
Cover a layer of zinc on the top of the galvanized square and rectangle steel pipe.
