The economical all-purpose structural plate
Q235B hot rolled steel plate is a low-carbon structural plate produced to جيجابايت/ت 700 and supplied per جيجابايت/ت 3274. The hot rolling process forms a characteristic mill-scale surface and delivers consistent plate geometry, flatness and through-thickness mechanical properties.
Offering dependable strength, easy welding and outstanding value, Q235B plate is the standard choice for building structures, bridge fabrication, general machinery, صهاريج التخزين, ship components and heavy welded assemblies — available in thicknesses from 2 مم ل 200 mm with full cutting and processing support.
