China Supplier Hot DIP Galvanized Steel Pipe
Galvanized pipe is a metal pipe whose surface is covered with a layer of zinc. It has good anti-corrosion properties and durability and is widely used in construction, municipal administration, industry and other fields.
Features
The manufacturing process of galvanized pipes mainly includes the following steps:
1. Steel cutting: Cut the steel into the required length.
2. Steel pipe rust removal: Sandblast the surface of the steel pipe to remove rust and oxide scale on the surface.
3. Galvanizing treatment: Put the rust-removed steel pipe into a galvanizing tank, and after electrolytic deposition, a dense zinc layer is formed on the surface of the steel pipe.
Application
Hot-dip galvanized pipe: Hot-dip galvanized pipe is a steel pipe that is heated at high temperature and then immersed in a galvanizing solution to form a thick zinc layer, which has high anti-corrosion performance and durability.

Proper packaging is essential for galvanized steel pipes during international transportation to prevent rust, deformation, and surface damage caused by moisture, impact, or environmental factors. ROYAL GROUP applies professional export packaging methods to ensure products arrive safely at the destination.
1.Packaging Requirements
Steel pipe surfaces are cleaned and dried before packing to ensure they are free from oil, dust, and impurities.
Pipes are protected with double-layer packaging, including waterproof plastic-coated paper and polyethylene protective film to prevent moisture and corrosion.
Each bundle is clearly marked with product information, including pipe type, specification, batch number, and production date for easy identification.
Pipes are classified and packed according to size, diameter, wall thickness, and length to improve loading efficiency and warehouse management.
2.Professional Packaging Method
Before shipment, galvanized pipes undergo surface inspection and cleaning to maintain excellent appearance and corrosion resistance.
Both ends of the pipes are reinforced with protective materials to prevent deformation and damage during handling and transportation.
Export-standard packing materials with moisture-proof, waterproof, and rust-resistant properties are used for long-distance shipping.
Bundles are securely strapped to ensure stability during container loading, sea transportation, and unloading.
3.Shipping & Storage Precautions
Packaging dimensions are carefully controlled to maximize container space utilization and reduce transportation costs.
Each package is labeled and categorized for convenient inventory management.
Proper stacking methods are applied to prevent pipe bundles from tilting, collapsing, or being damaged during storage and transportation.
With professional packaging processes and strict quality control, ROYAL GROUP ensures galvanized steel pipes are delivered safely, efficiently, and in excellent condition to customers worldwide.
