5 inch Nominal Pipe Size (NPS) Galvanized Steel Pipe with a Schedule 40 wall thickness (0.258"), available in 21 ft lengths. Conforms to ASTM A53 Grade B with 60,000 PSI tensile strength. The hot-dip zinc coating provides superior corrosion resistance for outdoor and high-moisture use. This large diameter pipe is ideal for structural columns, main water lines, and industrial process piping.

Galvanized Pipe Schedule (40) - 5 Inches meet the most stringent European and American standards, particularly EN 10240 and ASTM A53.

This 5" NPS Schedule 40 galvanized steel pipe provides exceptional structural integrity and long-term corrosion resistance. Manufactured to ASTM A53 Grade B specifications, it offers a 60,000 PSI tensile strength, making it ideal for demanding outdoor applications and fluid conveyance systems. In stock Los Angeles.

Specification

Construction:

Structural columns, scaffolding, and protective bollards - high strength and weather resistance.

Waterworks:
Main water lines and industrial process piping - large bore for high flow rates and corrosion protection.

Fencing & Security:

Heavy-duty gate frames and perimeter fence posts - resists environmental degradation.

Agriculture:

Pen construction and irrigation system main lines - withstands harsh outdoor conditions.

We use cold-drawn machines to form steel into round tubes. These machines are computer-controlled, resulting in diameter tolerances of just ±0.1 mm. This means every tube in a batch is identical, making installation easier for your customers. After processing, we pickle the tubes to remove any rust or scale, ensuring a secure adhesion of the subsequent zinc coating.

Next, hot-dip galvanizing occurs: we immerse each tube in a 450°C zinc bath to create the durable coating we mentioned earlier. After galvanizing, we inspect each tube using a magnetic thickness gauge to ensure a minimum zinc coating thickness of 275 g/m². Any tube that doesn't meet our standards will be rejected-we never let unqualified product leave our factory. Finally, we use a laser cutter to cut the tubes to your desired length (from 1 to 6 meters) with an accuracy of ±0.5 mm. Each batch of galvanized round tubes is also pressure-tested-we inject 1.6 MPa of water into the tubes to check for leaks. Only after they pass all tests are they packaged.

For wholesale customers, having a factory capable of handling large orders is crucial-and we have the capacity. We currently operate six fully automated galvanized round tube production lines. Each line can produce 1,000 meters of tube per day, bringing our monthly production capacity to approximately 180,000 meters.

If you need an order of 50,000 meters of steel pipe for a large customer, we can deliver it within two weeks-without waiting for material or delaying production. We also have a raw material warehouse that can hold 3,000 tons of steel coils, so we never run out of stock. We partner with a logistics company specializing in shipping to Europe and the United States and can arrange for containers to be shipped directly from our factory to your warehouse. We use an ERP system to track every order, allowing you to monitor production status at any time. Over the past two years, we've achieved an on-time delivery rate of 99.1%-we understand how crucial it is for you to receive your orders promptly. If you require custom lengths or diameters of galvanized round pipe, we can accommodate your needs-our machines can adjust sizes to produce pipes from 18mm to 1229mm in diameter.
