Product Description

Product Description

BOLTS & NUTS

Our full hard steel coil delivers exceptional strength and rigidity through precision cold rolling without annealing, complying with GB/T, JIS, and ASTM standards. Available in various thicknesses (0.15-2.0mm) and widths, it can be customized in steel grades and surface conditions.

The product offers high tensile strength, good flatness, and cost efficiency, making it ideal for applications requiring minimal forming. Widely used in light steel framing, purlins, pipe manufacturing, and general engineering, it provides a strong and economical material solution.

BOLTS & NUT

Produced from high-quality carbon steel through precision cold rolling without annealing, our full hard steel coil delivers consistent mechanical properties, high tensile strength, and excellent rigidity, complying with GB/T, JIS, and ASTM standards.

The product features good flatness, uniform thickness, and cost efficiency, with unprocessed surface condition ideal for applications requiring minimal forming. Available in various thicknesses (0.15-2.0mm), widths, and steel grades (Q195, Q235, SPCC-1B), it can be further processed into slit strips or cut-to-length sheets as required.

Widely used in light steel framing, purlins, pipe manufacturing, and general engineering applications.

We offer customization in material grade, thickness, width, and edge condition, along with value-added services including slitting, cutting, and protective oiling as specified.
