    ❓ 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 with an oxide layer, and is typically used for structural applications. Cold-rolled flat steel is processed at room temperature, offering a smoother surface and tighter dimensional tolerances, making it ideal for precision components.
    Q What thickness and width options are available for flat steel?
    Hot-rolled flat steel is available in thicknesses from 1.5 mm to 60 mm and widths from 10 mm to 300 mm. Cold-rolled flat steel ranges from 1 mm to 16 mm in thickness and 10 mm to 300 mm in width. Standard length is 6 meters, with customization available.
    Q Which material grade should I choose for corrosion-resistant applications?
    For corrosion-resistant applications, stainless steel flat bars — particularly grades 304 and 316 (AISI) — are recommended. Grade 316 offers superior resistance to chlorides and is ideal for marine or chemical environments, while 304 is suitable for general food-grade and industrial use.
    Q What international standards does your flat steel comply with?
    Our flat steel products comply with multiple international standards including GB/T 704, GB/T 6723 (Chinese national standards), ASTM A36 and ASTM A240 (American standards), as well as JIS standards. Please contact us if you require compliance with specific regional or industry standards.
    Q Can flat steel be customized in length or cut to specific dimensions?
    Yes. While the standard length is 6 meters, we offer customizable lengths to meet your project requirements. Our precision rolling and cutting processes ensure dimensional accuracy of ±0.1 mm, and we support downstream processing such as drawing, welding, and heat treatment.
    Q What industries commonly use flat steel bars?
    Flat steel bars are widely used across construction (beams, brackets), machinery manufacturing (shafts, linkages), automotive (chassis, body parts), shipbuilding and bridge engineering, as well as hardware tools and furniture frame production. Their versatility makes them one of the most commonly specified steel products globally.
