Hemaokang Steel (Shandong) Co., Ltd. is proud to introduce our premium Galvanized Steel Pipe 48.3mm OD 3.2mm Wall Hot Dip Galvanized for Scaffolding Construction. As a reliable manufacturer with annual export value exceeding US$50 million, we ensure that every pipe meets the highest standards of durability and safety for demanding construction projects. Our hot dip galvanizing process provides superior corrosion resistance, making these pipes ideal for outdoor scaffolding systems that require long-term performance.
Key Features & Technical Specifications
- Precise Dimensions: Outer diameter 48.3mm (1.9 inches) with wall thickness 3.2mm, compatible with standard scaffolding couplers and fittings.
- Hot Dip Galvanized Coating: Uniform zinc coating thickness of 50-85μm per ASTM A123, offering excellent protection against rust and weathering.
- High Strength Material: Manufactured from Q235 or Q195 carbon steel, with tensile strength ≥ 370 MPa and yield strength ≥ 235 MPa, suitable for heavy load-bearing scaffolds.
- Versatile Length Options: Standard 6m lengths are available, with custom lengths (1m–12m) upon request to meet various project requirements.
- ISO9001 Quality Management: Our production facility is ISO9001 certified, ensuring consistent quality through strict process control and testing.
- Easy Installation: Smooth surface and precise roundness allow quick connection with scaffold clamps, reducing labor time on site.
- Cost-Effective Solution: Compared to stainless steel, our galvanized pipes offer similar corrosion resistance at a fraction of the cost, making it a preferred choice for temporary and permanent structures.

Why Choose Our Galvanized Steel Pipe?
Our 48.3mm OD scaffolding pipe is engineered to provide reliable performance in various construction environments. The hot dip galvanized finish not only protects against corrosion but also reduces maintenance costs over the product's lifespan. With a zinc coating weight of over 350 g/m², the pipe can withstand harsh outdoor conditions including rain, humidity, and temperature fluctuations, ensuring safety for workers at height.
The 3.2mm wall thickness offers an optimal balance between strength and weight, making it easy to handle while still supporting heavy loads. The pipes are manufactured with strict tolerance control, guaranteeing compatibility with standard scaffolding systems such as ringlock, cuplock, and kwikstage. Whether you are building a residential scaffold or a large industrial structure, our pipes deliver consistent quality.
Additionally, we offer flexible packaging options such as bundles with steel straps, waterproof wrapping, or palletization to suit different shipping requirements. All pipes are inspected before shipment to ensure no defects, bends, or coating damage.

Frequently Asked Questions
-
Q: What is the difference between hot dip galvanized and pre-galvanized pipe?
A: Hot dip galvanized (HDG) pipe is dipped in molten zinc after fabrication, resulting in a thicker coating (typically 50–85μm) that provides superior corrosion resistance. Pre-galvanized pipe has a thinner coating applied before forming, making HDG more suitable for outdoor scaffolding exposed to weather. -
Q: Can this pipe be used for load-bearing scaffolding?
A: Yes, with a 3.2mm wall thickness and Q235 material, it meets the strength requirements for standard scaffolding systems. We recommend consulting your local scaffolding regulations for specific load ratings. -
Q: What lengths are available?
A: Standard length is 6 meters. Custom lengths from 1m to 12m are available upon request. Please specify your requirement when ordering. -
Q: Do you provide certificates?
A: Yes, we provide ISO9001 certification and can issue mill test certificates (MTC) showing chemical composition and mechanical properties upon request. -
Q: How is the pipe packaged for export?
A: Pipes are bundled with steel straps, wrapped in waterproof plastic, and loaded into containers. We also offer palletization for smaller orders. Packaging can be customized per buyer's request. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 5 tons for standard sizes, but we are flexible for trial orders. Please contact our sales team for details. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer samples with a small fee and shipping cost. The sample fee will be refunded upon bulk order. -
Q: How long does delivery take?
A: For standard sizes, production takes 10–15 days after deposit. Shipping time depends on destination port, typically 20–35 days by sea.
