    Frequently Asked Questions
    Q
    What is the difference between hot-rolled and cold-rolled flat steel?
    Hot-rolled flat steel is produced at high temperatures, resulting in a rougher surface and a wider thickness range (1.5–60 mm). Cold-rolled flat steel is processed at room temperature, offering a smoother surface, tighter dimensional tolerances, and a thickness range of 1–16 mm. Cold-rolled is preferred where surface finish and precision are critical.
    Q
    What standards does your flat steel comply with?
    Our flat steel products comply with major international and Chinese standards including GB/T 704, GB/T 6723, ASTM A36, and ASTM A240, ensuring compatibility with global project requirements and quality specifications.
    Q
    Which flat steel material is best for corrosion-resistant applications?
    Stainless steel flat bars, particularly grades 304 and 316 (AISI), are the best choice for corrosion-resistant applications. Grade 316 provides superior resistance to chlorides and is widely used in chemical processing, marine environments, and food industry equipment.
    Q
    Can flat steel be customized in length and dimensions?
    Yes. While the standard length is 6 meters, we offer fully customizable lengths and dimensions to meet specific project requirements. Width ranges from 10–300 mm and thickness from 1–60 mm depending on the rolling process. Please contact us with your specifications for a tailored quote.
    Q
    What industries commonly use flat steel bars?
    Flat steel bars are widely used across construction (beams, brackets), machinery manufacturing (shafts, linkages), automotive (chassis and body parts), shipbuilding and bridge structures, as well as hardware tools and furniture frame fabrication.
    Q
    What dimensional precision can you achieve in flat steel production?
    Using advanced high-speed rolling and controlled cooling technologies, we achieve dimensional precision of ±0.1 mm. This level of accuracy ensures consistent quality and supports downstream processes such as drawing, machining, and heat treatment.
