Detailed Product Description
Our Square Galvanized ERW Welded MS GI Steel Pipe is manufactured using advanced cold-forming and high-frequency ERW welding technology. The resulting hollow rectangular section combines the strength of mild steel with the corrosion resistance of a zinc coating. This product is widely used in structural applications where weight reduction and load capacity are critical.
Each pipe undergoes strict quality control during production, including dimensional inspection, surface condition checks, and weld integrity testing. The galvanized coating provides long-lasting protection against rust, making it suitable for both indoor and outdoor use. We offer two types of galvanizing: hot-dip galvanized (HDG) for heavy-duty corrosion protection, and pre-galvanized (electro-galvanized) for cost-effective applications.
Our rectangular tube is available in standard lengths of 6 meters, but custom lengths can be cut per your request. The hollow profile allows for easy integration into structural frames, supports, and trusses. With a smooth surface finish, it is also ideal for aesthetic applications such as handrails and architectural elements.
Typical applications include:
- Building structures (columns, beams, roof trusses)
- Agricultural greenhouses and livestock enclosures
- Industrial racking and shelving systems
- Solar panel mounting frames
- Fencing, gates, and safety barriers
- Automotive and transportation components

Q: Can you provide custom lengths?
A: Yes, we can cut to any length required, typically up to 12 meters. Please specify your requirements when ordering. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 1 ton. For customized sizes, MOQ may be 5 tons. We welcome trial orders. -
Q: How is the pipe packaged for export?
A: Pipes are bundled with steel straps, wrapped in waterproof plastic, and loaded into containers. Sea-worthy packaging is standard. -
Q: What is the delivery time?
A: Typically 15-25 days after deposit, depending on order quantity and customization. -
Q: Do you offer samples?
A: Yes, samples are available. Freight cost is paid by customer, but we can deduct from bulk order. -
Q: Can you supply the pipe with other standards like ASTM A500?
A: Yes, we can produce according to ASTM A500, EN 10219, or other standards upon request. -
Q: Is the pipe suitable for welding?
A: Yes, the ERW welded seam and base material are weldable. However, proper welding procedures should be followed.
