    Frequently asked questions

    We stock carbon steel round bars in diameters from dia 10mm to dia 300mm. Standard lengths are 3m or 6m, but we offer custom cutting to your required length, even for small quantities.

    Absolutely. We offer quenched and tempered (Q&T) treatment for grades like 4140 and 4340 to achieve required hardness (e.g., HRC 28-35). Pre-hardened steel saves you time and cost on secondary processing.

    Our MOQ is flexible. For standard sizes, it can be as low as 1 ton. We also support trial orders and small quantity samples to start our cooperation.

    For standard products in stock, lead time is 5-7 days. For customized processing, it takes 10-15 days. We offer technical support for material selection and processing. Any quality issues are addressed promptly with replacements or refunds
