Welcome to Hemaokang Steel (Shandong) Co., Ltd. As a trusted supplier in the global steel market, we are proud to offer our Hot Rolled Coil for Pipe and Tube Manufacturing – JIS G3131 SPHC, 2.0mm-14mm Thick, Pickled Coils. This product is specially engineered to meet the demanding requirements of pipe and tube producers, delivering consistent mechanical properties and a clean surface finish. Manufactured under strict quality control, our SPHC pickled coils ensure excellent weldability, formability, and dimensional accuracy — essential for downstream processing. With an annual export value exceeding US$50 million and a customer base spanning North America, South America, Europe, Africa, and beyond, Hemaokang Steel is your reliable partner for high-quality steel solutions.
Product Features & Technical Specifications
Our hot rolled SPHC pickled coils are produced in accordance with JIS G3131 standard, specifically designed for pipe and tube manufacturing. The pickling process removes scale and provides a smooth, oxide-free surface, which significantly improves subsequent forming operations and coating adhesion. Below are the key characteristics and benefits:
- Material Grade: SPHC (JIS G3131) – a low carbon hot rolled steel with excellent drawing and forming properties.
- Thickness Range: 2.0mm to 14mm – suitable for a wide variety of pipe sizes, from thin-walled tubes to heavy-duty pipes.
- Surface Treatment: Pickled (acid washed) to remove mill scale, providing a clean and uniform surface for welding and painting.
- Width Options: Customizable from 1000mm to 2000mm, with slitting capability for narrower strips if required.
- Mechanical Properties: Typically tensile strength ≥270 MPa, yield strength ≤210 MPa, elongation ≥31% (depending on thickness).
- Coil Weight: Up to 30 tons per coil, ensuring efficient production runs and reduced handling costs.
- Weldability: Low carbon content makes SPHC ideal for high-frequency straight seam welding and spiral welding processes.
- Consistent Quality: ISO9001 certified production line with real-time dimensional monitoring and hardness testing.

Customer Benefits
Using our SPHC pickled coils in your pipe and tube manufacturing offers distinct advantages:
- Enhanced Productivity: The pickled surface eliminates descaling operations, saving time and reducing abrasive consumption.
- Superior Weld Quality: Consistent thickness and clean surface minimize weld defects and rework.
- Cost Efficiency: High coil weight means fewer coil changes, lower downtime, and reduced scrap.
- Flexibility: The wide thickness range (2.0–14mm) covers applications from thin-wall tubing for furniture to heavy-wall pipes for structural use.
- Global Logistics: Reliable packing (eye-to-side, vertical, or horizontal) ensures safe transit to any market worldwide.

Frequently Asked Questions (FAQ)
Q1: What is the difference between SPHC and other hot rolled grades like SPHD or SPHE?
A: SPHC is a general drawing quality grade suitable for many common forming operations. SPHD and SPHE offer deeper drawing capabilities with higher elongation requirements. For pipe and tube manufacturing, SPHC is often preferred due to its balanced strength and formability.
Q2: Are the pickled coils oiled to prevent rust during transit?
A: Yes, we offer both dry (non-oiled) and oiled surface options. Oiled coils receive a thin rust-preventive oil film, which is typically applied upon customer request. Dry coils are suitable for processes where oil may interfere with welding or coating.
Q3: Can you supply coils narrower than 1000mm?
A: Absolutely. We can slit master coils into narrower widths according to your specifications. Slitting tolerances are precise to ensure uniform strips for tube forming.
Q4: What certifications or test reports do you provide with each shipment?
A: We provide an ISO9001 quality certificate and a mill test certificate (MTC) showing chemical composition, mechanical properties, and dimensions. Additional third-party inspection is available upon request.
Q5: How do you ensure the surface is free from lamination or defects?
A: Each coil undergoes ultrasonic or visual inspection (depending on customer specification). Our pickling process also reveals any surface defects, and non-conforming material is rejected.
Q6: What is the typical lead time for an order?
A: Standard lead time is 15–25 days after receipt of deposit, depending on the quantity and special requirements. For urgent orders, we can expedite subject to stock availability.
Q7: Do you offer custom packing for export?
A: Yes, we pack coils in accordance with international shipping standards: steel strapping, plastic wrapping, and edge protection. For sea freight, coils are loaded in containers or flat racks as needed.
Q8: What payment terms do you accept?
A: We accept T/T, L/C, and other flexible terms based on mutual agreement. For new customers, a 30% deposit with 70% balance against copy of shipping documents is typical.
