Q195/Q215 Hot-rolled Steel Coil

Q195 is a common carbon structural steel in the national standard GB/T 700, belonging to low-carbon mild steel. It has a low carbon content, excellent plasticity and toughness, excellent welding and cold-working properties, relatively low strength, and low cost. It is widely used in stamping parts, welded steel pipes, strapping, hardware accessories, light supports, and general structural components with low strength requirements, making it a cost-effective basic material.

Product Performance Advantages

Q195 Advantages: Excellent plasticity and toughness, ideal for stamping, stretching, bending, and pipe rolling; excellent weldability, making it the preferred material for welded pipes and structural components; lowest cost, extremely high cost-effectiveness, suitable for mass production of structural components; good surface quality, easy to process and paint; wide range of applications; large market demand.

Q215 Advantages: Slightly higher strength than Q195, better load-bearing capacity, still very good plasticity, weldable, bendable, and stampable; price close to Q195, but with superior structural safety; widely used in light steel structures, supports, purlins, flat steel, fences, etc.

Our factory's advantages in producing Q195/Q215 series products:

We offer precise control over the composition of Q195 and Q215 materials, ensuring stable and consistent mechanical properties that meet national standards and export requirements, with minimal batch-to-batch quality fluctuations.

We offer a complete range of specifications to meet foreign trade demands. We can produce various forms including hot-rolled plates, coils, flat sheets, flat bars, strips, and welded pipe blanks. Thickness, width, and length can be customized to customer orders, satisfying diverse applications in engineering, hardware, and pipe manufacturing across different countries.

We boast significant cost advantages and outstanding cost-effectiveness. Our large-scale production and stable supply chain allow us to offer stronger price competitiveness while maintaining quality, making us particularly suitable for large-volume, long-term, and stable overseas buyers.

Our products exhibit good plasticity, do not crack when bent, and weld smoothly, making them particularly suitable for downstream stamping, pipe manufacturing, light steel structures, and hardware processing. Customer feedback has been excellent. Each batch comes with a complete Material Certificate (MTC), ensuring traceability of chemical composition and mechanical properties, meeting the quality requirements for long-distance sea freight, and reducing customer complaints and usage risks.

With ample stock and flexible production scheduling, we can quickly respond to foreign trade orders, support full container load (FCL) and less than container load (LCL) shipments, ensure smooth customs clearance and logistics, and have extensive experience serving overseas customers.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
