A: Q235 is a general-purpose carbon structural steel with moderate strength, suitable for non-critical structural parts. Q345 (also known as 16Mn) offers higher yield and tensile strength, better low-temperature toughness, and is ideal for heavy-load structures, bridges, and pressure vessels.
A: Yes. Every shipment includes a Mill Test Certificate (MTC) compliant with EN 10204 3.1. Additional third-party certifications (SGS, BV, TÜV) are available upon request.
A: Absolutely. We offer sample coils (minimum 100kg) for testing and accept small batch orders. Lead time for samples is typically 5–7 working days.
A: Our production follows ISO 9001 procedures with in-line inspection at rolling, coiling, and packaging stages. Chemical composition and mechanical properties are verified per heat number. Surface defects are monitored via automated vision systems.
