Why choose our EN 39 scaffolding pipe? The 48.3mm x 4.0mm size is the most widely used specification in global scaffolding systems. Our pipes are manufactured using advanced cold-rolling technology and undergo strict quality control at every stage – from raw material inspection to final galvanizing. The result is a product with uniform wall thickness, smooth surface, and excellent weldability. Compared to cheaper alternatives, our pipes offer higher strength-to-weight ratio and longer service life, reducing replacement costs for your projects.
Applications: Ideal for construction scaffolding, temporary structures, exhibition stands, shoring systems, and industrial maintenance platforms. Compatible with popular scaffolding couplers such as drop-forged swivel clamps, right-angle couplers, and sleeve couplers.
Quality Assurance: Each pipe is tested for dimensional accuracy, tensile strength, yield strength, and coating thickness. We provide mill test certificates (MTC) for every batch, ensuring traceability and compliance with EN 39 requirements.

Frequently Asked Questions (FAQ)
-
Q: Is this pipe suitable for ringlock or cuplock scaffolding systems?
A: Yes, the 48.3mm outer diameter is the standard size used in most modular scaffolding systems. However, for specific systems like ringlock, the pipe is often used as a standard or ledger, but you may need to confirm compatibility with your specific hardware. We can also supply pipes with pre-welded discs or cups upon request. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, our MOQ is typically 10 tons per specification. For custom lengths or special treatments, MOQ may be higher. Please contact our sales team for exact details based on your requirements. -
Q: Do you provide third-party inspection services?
A: Yes, we can arrange third-party inspection by SGS, BV, or other accredited agencies at the buyer's expense. We also provide our own mill test certificates issued by our ISO9001-compliant quality lab. -
Q: How long is the delivery time?
A: For standard sizes and quantities, delivery is usually within 15-20 working days after confirmation of order and deposit. For large orders or customized products, delivery may take 25-30 days. We will always confirm the schedule in advance. -
Q: Can the pipe be supplied with threaded ends?
A: Yes, we can provide threaded ends (e.g., BSPT or NPT threads) as per your requirements. Please specify the thread type and length when placing an order. -
Q: Is the galvanized coating uniform and durable?
A: Absolutely. Our hot-dip galvanizing process ensures a uniform coating thickness that meets EN ISO 1461 standards. The coating provides excellent adhesion and corrosion resistance, typically lasting 20-30 years in normal atmospheric conditions. -
Q: What is the difference between EN 39 and BS 1139?
A: EN 39 is the European standard that replaced BS 1139 for steel tubes used in scaffolding. Both standards have similar dimensional requirements. Our pipes comply with the current EN 39 standard, which is widely accepted in the UK, Europe, and many other regions. -
Q: Do you have stock available for urgent orders?
A: Yes, we maintain a certain stock level of standard 48.3mm x 4.0mm pipes in 6-meter lengths. For urgent requirements, please contact us to check current availability. We can expedite shipments if needed.
