Dab tsi yog qhov kev qhia tshwj xeeb (thickness / dav) ntawm Q235 steel coils rau kev tsim kho?
A: Thickness 1.5-20mm (feem ntau 2.0-12mm), dav 1000-1800mm (feem ntau 1250/1500mm), ntev hauv coil (tus qauv txiav kom loj raws li xav tau).
Dab tsi yog qhov sib xyaw ua ke ntawm Q235 steel coils tom qab txiav?
A: Tom qab txiav, lawv dhau los ua daim hlau tiaj tus, feem ntau 6000-12000mm ntev, thiab tuaj yeem txiav mus rau qhov ntev ntawm cov khoom siv (xws li, kem puag daim hlau, purlins).
Dab tsi yog qhov txawv ntawm Q235 steel coils thiab Q235 steel daim hlau? Yuav ua li cas xaiv ntawm lawv rau kev tsim kho?
A: Hlau coils yog cov khoom siv coiled, haum rau batch, kev ua haujlwm tas mus li (purlins, profiled sheets); steel phaj yog cov phaj tiaj tiaj ntawm tus qauv ntev, haum rau ib qho - thooj, tsis xwm yeem - zoo li kev ua haujlwm (node plates, embedded parts).
Qhov hnyav ntawm Q235 steel coils suav li cas?
A: Theoretical hnyav (kg)=Thickness (mm) × Dav (m) × Length (m) × 7.85 (steel density 7.85t/m³).
Dab tsi yog qhov yuav tsum tau ua siab ntev rau Q235 steel coils hauv kev tsim khoom?
A: Thickness kam rau ua ** ± 0.15-0.3mm ** (qib raws li tuab), dav kam rau ua ** +5/-0mm **, flatness ≤3mm / m, ua raws li GB / T 14977 tus qauv.
