Detailed Advantages for Your Production
- Pipe making optimized: The SPHT series is widely used for electric resistance welded (ERW) pipes. Our coils feature proper metallurgical structure that promotes smooth forming and reliable welding on high-speed mills.
- General fabrication flexibility: From chassis parts to storage racks, these coils can be punched, bent, and cut with ease. The material responds well to standard machining processes.
- Uniform thickness control: Advanced hot rolling mills ensure tight thickness tolerances, reducing material waste and improving end product consistency.
- Surface quality: Our coils offer a clean surface with minimal defects, which is important for coating and painting processes downstream.
- Packaging protection: Coils are secured with anti-corrosion wrapping, steel strapping, and suitable edge protection to withstand long ocean voyages.

Frequently Asked Questions
-
What is the difference between SPHT1, SPHT2, and SPHT3?
The grades differ mainly in tensile strength and ductility. SPHT1 has lower strength with higher ductility for light forming; SPHT2 is well balanced for general pipe making; SPHT3 offers higher strength for structural applications. -
Can I get the coils in customized widths?
Yes, we can customize the width based on your order volume. Common slit widths range from 600mm to 2000mm. Please provide your exact requirement. -
Are these coils suitable for ERW pipe production?
Absolutely. The SPHT series is specifically designed for high-frequency ERW pipe making, offering excellent formability and weldability. -
Do you provide mill test certificates?
Yes, a mill test certificate is available upon request. It provides detailed chemical composition and mechanical property results for each heat number. -
What surface options are available?
Our standard product is black hot rolled surface. Pickled and oiled surface is also available as an option for customers who need a cleaner finish. -
What is the minimum order quantity?
Typical MOQ is one 20-foot container load, but smaller trial orders can be discussed. Please contact our sales team for specifics. -
How are the coils packed for ocean shipping?
Coils are packed with moisture-resistant paper, steel strapping, and edge protectors. They can be loaded in containers or as break-bulk cargo depending on weight and port requirements. -
Can you supply cut-to-length sheets?
Yes, we can supply sheets cut to your specified lengths. This processing is available upon request and may affect lead time.
