Galvanized Pipe

 

 

Galvanized steel pipes are steel pipes that have undergone a galvanization process, where a protective layer of zinc is applied to prevent rust and corrosion. This process makes galvanized steel pipes ideal for outdoor and industrial applications where the pipes may be exposed to harsh environments. The zinc coating provides a durable and long-lasting shield, extending the life of the steel underneath.

Galvanized Steel Tubes Q235

Advantages Of Galvanized Pipe

 

 

Excellent Rust Protection

The zinc layer provides cathodic protection, preventing the steel pipe from rusting. It offers a service life of up to 20-30 years in outdoor environments.

High Strength & Durability

Ideal for load-bearing structures, scaffolding, guardrails, and more. It is resistant to pressure and impact.

Variety of Surface Treatments

Available in pre-galvanized or post-galvanized options to meet different corrosion resistance requirements.

Convenient Installation

Can be threaded or welded, making it suitable for quick construction.

Eco-Friendly and Safe

RoHS compliant, lead-free, and non-toxic. Suitable for drinking water delivery systems (GB/T 3091).

 

Main Application Areas

 

Construction & Steel Structure

Scaffolding, parapets, roof supports, building frames (GB/T 3091).

01

Municipal Engineering

Water supply pipes, fire-fighting pipes, gas transmission (low pressure, according to GB/T 3091).

02

Electricity & Communication

Cable protection pipes, wire casings (galvanized feeder pipes).

03

Agriculture & Greenhouse

Greenhouse frames, irrigation systems, livestock fencing.

04

Industry & Machinery

Ventilation ducts, conveying systems, equipment supports.

05

How to store galvanized pipes

 

The site or warehouse where the galvanized steel pipe is placed should be located in a clean and well-drained place, away from factories and mines that generate harmful gases or dust. Weeds and all debris should be removed from the site, and the galvanized steel pipe should be kept clean. In the warehouse, it is not allowed to stack together with corrosive materials such as acid, alkali, salt, cement, etc. Different varieties of square tubes should be stacked separately to prevent confusion and contact corrosion. Large sections, rails, steel plates, large-diameter steel pipes, forgings, etc. can be stacked in the open air.


Some small square pipes, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled, galvanized steel pipes and metal products with high prices and easy corrosion can be stored in the warehouse. The warehouse should be selected according to the geographical conditions. Generally, an ordinary closed warehouse is used, that is, a warehouse with a roof, walls, tight doors and windows, and a ventilation device.
