Оцинкованная сталь pipe is a core material in today’s construction, industry and infrastructure fields. Its unique anti-corrosion properties and high mechanical strength make it a revolutionary alternative to traditional steel pipes. Through the hot-dip galvanizing process, a dense zinc-iron alloy layer is formed on the surface of the steel pipe, which increases the corrosion resistance by 3-5 times and has a service life of more than 50 years.

Weather resistance: The zinc layer isolates air moisture and effectively resists atmospheric corrosion, soil corrosion and chemical medium corrosion.

Maintenance-free: The self-healing properties of zinc (sacrificial anode protection) can repair tiny scratches.

Economical: The purchase cost is lower than stainless steel, and the maintenance cost is lower than ordinary carbon steel pipes.

High-rise building skeleton: galvanized steel pipe as SC structural column

Scaffolding system: quick-detachable galvanized steel pipe scaffolding

Roof drainage system: K-shaped/semicircular downpipe

Fire protection pipe network: NFPA-compliant, with grooved fittings for quick connection

Water supply and delivery system: replace cast iron pipes, reducing 80% scale accumulation

Solar support: C-type/Z-type galvanized support (salt spray test > 1000 hours)

Modular building: prefabricated galvanized steel pipe frame

Vertical farm: thin-walled precision pipe fittings (Φ25mm-50mm) nutrient solution delivery system

Electric vehicle battery rack: high-strength galvanized square tube (impact strength ≥ 500MPa)

Q: What is the lifespan of galvanized steel pipes in seawater environments?

A: >50 years in conventional environments, about 20-30 years within 500 meters of the coast (it is recommended to use zinc-aluminum-magnesium coating to increase to 40 years).

Q: How to identify inferior galvanized pipes?

A: Three-view rule: look at the surface (uniformity of zinc flowers), look at the incision (no black slag), and look at the certificate.

Q: Precautions for welding galvanized pipes?

A: The welding area must be polished in advance and low-hydrogen electrodes (such as E7018) must be used. Zinc-rich paint (zinc content ≥92%) must be applied after welding.
