DN25 Gi Pipe 1 Inch Galvanized Steel Tube

Our DN25 galvanized steel pipes are manufactured to the highest international standards, providing a robust and long-lasting solution for fluid conveyance and structural applications. The hot-dip galvanizing process ensures a thick, uniform zinc layer that offers exceptional protection against rust and corrosion, making these pipes ideal for demanding environments, both indoors and outdoors.

Excellent Corrosion Resistance: The hot-dip galvanizing process provides a thick, adherent zinc coating that acts as a sacrificial anode, ensuring decades of service life, even in harsh conditions.

High Pressure Resistance: Made from high-grade steel, our DN25 pipes can withstand significant internal pressure, making them safe and reliable for water and gas systems.

Durable & Long-Lasting: The combination of strong steel and a robust zinc coating results in a product with superior mechanical strength and impact resistance.

Compliant with Int'l Standards: Our pipes are produced according to ASTM A53, BS 1387, and EN 10255, guaranteeing consistent quality and performance.

Easy Installation: Can be easily threaded, cut, and welded (with post-weld treatment) for quick and efficient installation on site.

Versatile Application: Suitable for a wide range of uses, from plumbing and fire sprinklers to fencing and structural frames.

1. Vs. Black Steel Pipe 

Galvanized (DN25): Has a zinc coating for excellent corrosion resistance. Ideal for water, gas, and outdoor use. More expensive than black steel.

Black Steel: No coating. Prone to rust quickly. Used for structural applications or concealed gas/water lines where it stays dry. Cheaper upfront cost.

Key Difference: Corrosion resistance. Choose galvanized for exposure to moisture or weather.

Packaging: Standard export packaging. Bundled tightly with steel straps and protected with plastic caps on both ends. Optional waterproof paper or PVC wrapping available for long-sea voyage protection.

Bundle Weight: Approx. 2-3 tons per bundle for easy handling.

Shipping: We support FCL, LCL, and air freight shipments worldwide. We handle all export documentation professionally.

Lead Time: Typically 15-25 days after receiving deposit for mass production. Samples available.

Q1: What is the difference between DN25 and 1 inch?
A: DN25 is the "Diameter Nominal" metric designation. It is the standard equivalent to the imperial 1 Inch Nominal Pipe Size (NPS). Both refer to a pipe with an outer diameter of 33.7 mm.

Q2: Can I get the pipes threaded?
A: Yes, we can provide pipes with threaded ends. Common thread types are BSP (British Standard Pipe) and NPT (National Pipe Tapered). Please specify your requirement when ordering.

Q3: Are these pipes suitable for outdoor fencing?
A: Absolutely. The hot-dip galvanized coating provides excellent protection against rain, humidity, and UV exposure, making these pipes a prime choice for durable and long-lasting fencing.

Q4: What certificates do you provide?
A: We can provide Mill Test Certificates (MTC) that comply with EN 10204 3.1, which verify the chemical composition and mechanical properties of the steel.

Q5: What is your MOQ?
A: Our standard Minimum Order Quantity (MOQ) is 5 ton. We can accept smaller orders for samples or trial purposes.
