S220GD Galvanized Steel Pipe

S220GD galvanized steel pipe is a high-strength, corrosion-resistant steel pipe made from hot-dip galvanized steel. It is primarily used in construction, infrastructure, and industrial applications due to its durability and resistance to rust, making it ideal for outdoor and marine environments. The “S220” in the designation refers to its minimum yield strength of 220 MPa, while the “GD” indicates its galvanized coating, which enhances protection against corrosion. This type of steel pipe combines the structural strength of steel with the protective benefits of zinc coating, providing a long-lasting, low-maintenance solution for various piping needs.

Our warehouse facility is strategically designed to handle and store S220GD Galvanized Steel Pipes efficiently and securely. The pipes are organized by size and type, making it easy to retrieve and prepare orders for shipment. We utilize advanced inventory management systems to maintain an accurate and up-to-date record of stock levels, ensuring that we can meet your specific needs quickly. The pipes are stored in a climate-controlled environment to protect them from any environmental elements that could affect the galvanized coating and overall quality. Our organized warehouse ensures prompt, reliable, and damage-free delivery of your S220GD Galvanized Steel Pipes, keeping your project timelines on track.

The appearance of the coating is bright, meticulous, without sagging or wrinkles. Thickness inspection can use coating thickness gauge, the method is relatively simple. The thickness of the coating can also be obtained by converting the amount of zinc adhesion. For the bonding strength, a bending press can be used to bend the sample at 90-180°, and there should be no cracks or peeling of the coating. A heavy hammer can also be used to test, and the salt spray test and copper sulfate corrosion test can be done in batches.

S220GD Galvanized Steel Pipe meets stringent dimensional tolerances per EN 10346 and ASTM A653 standards, with outer diameters spanning 21.3mm to 165mm and wall thicknesses from 1.5mm to 5.0mm. Standard lengths range from 3m to 12m (fixed or random), while custom cuts are supported for specialized projects. The zinc coating weight (60–275g/m²) is verified via magnetic thickness gauges, ensuring compliance with Z100-Z275 classifications. Critical parameters like ovality, straightness (±0.2% of length), and surface finish (smooth, spangle-free) are tested using laser profiling and eddy current systems. Mill test certificates (EN 10204 3.2) validate yield strength (220MPa min), tensile strength (300–420MPa), and elongation (≥20%), ideal for structural and automotive applications.

S220GD Galvanized Steel Pipe is packaged with robust safeguards to ensure damage-free transportation and storage. Each pipe is tightly strapped using corrosion-resistant steel bands and fitted with durable end caps to shield against moisture, dust, and mechanical impacts. For long-term storage or humid environments, pipes are wrapped in VCI (Volatile Corrosion Inhibitor) paper or PVC film to prevent white rust formation. Customizable packaging options, such as wooden crates, hexagonal bundles, or palletized configurations, are available for bulk orders. All packages are labeled with grade (S220GD), dimensions, coating weight, and batch numbers, complying with ISO 4042 standards for seamless global logistics and traceability.
