Product Overview
Gengfei Steel supplies hot-dip galvanized pipes with strong corrosion resistance, long service life, and a bright, clean surface. Manufactured according to AISI, ASTM, BS, DIN, GB, and JIS standards, these pipes are widely used in structural and outdoor applications such as fences, greenhouses, handrails, and construction.
The zinc coating not only enhances durability but also protects against weathering, making these pipes a cost-effective solution for both commercial and residential projects.
Galvanized Steel Pipe Real Pictures
Our galvanized steel pipes with excellent corrosion resistance are directly quoted from the factory. Depending on your project, you can choose hot-dip galvanized, cold-dip galvanized, seamless pipes and welded pipes to save you the cost of procurement. Length and thickness can also be customized.
Galvanized Steel Pipe Comparison
| Characteristic | Hot-Dip Galvanizing | Cold Galvanizing (Electrogalvanizing) |
|---|---|---|
| Zinc Layer Thickness | Thick (typically > 45μm) | Thin (typically 10-20μm) |
| Corrosion Resistance | Excellent | Good, but not as good as hot-dip galvanizing |
| Adhesion | Strong, metallurgical bond | Relatively weak, physical deposition |
| Surface Appearance | Slightly rough, industrial style | Smooth and delicate, aesthetically pleasing |
| Cost | Higher | Lower |
| Service Life | Long | Relatively short |
| Application Scenarios | Harsh environments, long-term corrosion protection needs | Indoor or dry environments, decorative requirements |
Seamless vs. Welded Galvanized Steel Pipes Comparison
| Characteristic | Seamless Galvanized Steel Pipe | Welded Galvanized Steel Pipe |
|---|---|---|
| Manufacturing Process | Made from a solid billet of steel that is heated and pierced to form a hollow tube. | Formed by rolling steel plates or strips and welding the edges together. |
| Strength | Generally higher strength and pressure rating due to uniform structure. | Strength is generally lower than seamless pipes; weld seam can be a potential weak point. |
| Pressure Rating | Higher pressure rating, suitable for high-pressure applications. | Lower pressure rating, generally used for lower pressure applications. |
| Cost | More expensive due to complex manufacturing process. | Less expensive, more cost-effective for many applications. |
| Application | High-pressure applications, critical pipelines in industries like oil & gas, chemical processing, and high-temperature services. | General applications such as water and gas lines, scaffolding, structural applications where high pressure is not a primary concern. |
Carbon Steel vs. Stainless Steel Galvanized Pipes Comparison
| Characteristic | Carbon Steel Galvanized Pipe | Stainless Steel Galvanized Pipe |
|---|---|---|
| Base Material | Carbon Steel (ferrous alloy with carbon as the main alloying element) | Stainless Steel (ferrous alloy with a minimum of 10.5% chromium) |
| Corrosion Resistance | Good corrosion resistance after galvanizing due to the zinc coating. | Excellent corrosion resistance even before galvanizing; galvanizing provides additional protection, especially in harsh environments. |
| Strength | Moderate to high strength, depending on the grade of carbon steel. | High to very high strength, generally stronger than carbon steel. |
| Cost | Lower cost, carbon steel is a common and economical material. | Significantly higher cost, stainless steel is a premium alloy with higher material and manufacturing costs. |
| Application | General piping, water lines, structural supports, and applications where good corrosion protection and moderate strength are required at a lower cost. | Highly corrosive environments, chemical processing, marine applications, food and beverage industry, and applications requiring superior corrosion resistance and high strength. |
