As a leading manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we are proud to offer our premium 1.5mm 2.0mm 3.0mm Thickness Galvanized Steel Pipe in 1-inch, 2-inch, and 3-inch diameters, produced with advanced ERW (Electric Resistance Welded) technology. Our GI pipes are designed to meet the rigorous demands of global construction and infrastructure projects, with customizable lengths to suit your specific requirements. Backed by our ISO9001-certified quality management system, we ensure consistent performance and durability in every pipe we deliver.
Our galvanized steel pipes are manufactured from high-quality steel coils, processed through strict ERW welding, and then hot-dip galvanized or pre-galvanized to provide excellent corrosion resistance. The available thickness options (1.5mm, 2.0mm, 3.0mm) and diameter sizes (1 inch, 2 inch, 3 inch) make these pipes versatile for a wide range of applications, including water conveyance, structural support, fencing, scaffolding, and mechanical engineering. With our custom length service, you can order pipes cut to exact lengths, reducing waste and installation time on site.
At Hemaokang Steel, we understand that quality and reliability are paramount for B2B buyers. Our factory in Liaocheng, Shandong, operates with 51-100 skilled employees and an annual export value exceeding US$50 million, serving markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. Every pipe undergoes rigorous testing to ensure dimensional accuracy, tensile strength, and uniform galvanization. Below, we detail the key features and specifications of our galvanized steel pipe series.
Key Features & Technical Specifications
- Material Quality: Made from prime steel grades (Q195, Q215, Q235) with guaranteed chemical composition and mechanical properties.
- Welding Process: ERW (Electric Resistance Welded) ensures a smooth, strong weld seam with minimal internal flash, suitable for both pressure and non-pressure applications.
- Galvanization: Available in hot-dip galvanized (HDG) with average zinc coating weight of 200-600 g/m², or pre-galvanized (electro-galvanized) for lighter protection. Both options provide excellent rust resistance.
- Dimensional Accuracy: Pipe outer diameter tolerance: ±0.5mm; wall thickness tolerance: ±0.1mm; length tolerance: ±5mm. All dimensions are in accordance with international standards.
- Custom Length Service: We can supply pipes in any length from 1.5m to 12m, or as per your project drawings. This reduces on-site cutting and material waste.
- End Finishing: Plain ends, beveled ends, threaded ends, or with couplings – all available upon request.
- Surface Condition: Smooth, free from oil stains, rust, and scale. Optional oiled or anti-rust coating for long-distance shipping.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between ERW and seamless galvanized pipe?
A: ERW pipes are manufactured by welding a steel coil into a tube, making them more cost-effective and with tighter dimensional tolerances. Seamless pipes are extruded without a weld seam, generally used for high-pressure applications. Our ERW pipes are suitable for most water, structural, and low-pressure gas lines. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer sample cuttings of 30-50cm length for quality evaluation. Samples are available at a nominal cost, which can be deducted from your first order. Please contact us for details. -
Q: What is the typical lead time for custom-length pipes?
A: For standard sizes (1.5mm, 2.0mm, 3.0mm thickness; 1-3 inch diameter), lead time is 15-20 days after order confirmation. Custom lengths may require an additional 3-5 days. We can expedite urgent orders upon request. -
Q: Do you provide a mill test certificate (MTC) with each shipment?
A: Absolutely. Every shipment includes a mill test certificate (MTC) showing chemical composition, mechanical properties, and galvanization test results. Third-party inspection (SGS, BV, etc.) can be arranged at buyer's cost. -
Q: What packaging options do you offer?
A: We use standard sea-worthy packaging: bundles with steel straps, waterproof plastic wrapping, and wooden pallets for small diameters. For custom lengths, we can also provide slat crates or wooden boxes for extra protection. -
Q: Can I mix different sizes and thicknesses in one container?
A: Yes, we support mixed loading. For example, you can combine 1-inch, 2-inch, and 3-inch pipes with different thicknesses in a 20-foot or 40-foot container. Our logistics team will optimize the loading plan to maximize space utilization. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% balance against copy of shipping documents), L/C at sight, or other terms negotiable for long-term partners. For first-time orders, we recommend T/T or L/C.
