FAQ .
Asɛmmisa: Dɛn nti na ɛsɛ sɛ wopaw hot-rolled sen cold-rolled ma galvanized mprɛte .?
A: Hot-rolled yɛ nea ɛho ka sua ma gauges a ɛyɛ den, ɛma ductility a eye ma bending kɛse, na ɛfata ma applications a ɛwɔ baabi a surface finish no ho nhia pii.
Asɛmmisa: So wobetumi de saa mprɛte yi adi dwuma wɔ kɔnkrit ho tẽẽ .?
A: Yiw, SGCC a wɔde kata so no gyina alkaline corrosion a efi kɔnkrit mu no ano; Fa bituminous primer a ɛma asase ase a ɛda adi bere tenten (sɛ nhwɛso no, fapem a wɔaboaboa ano) gu so.
Asɛmmisa: Dɛn ne dodow a ɛba fam koraa a wɔkra ma amanne akɛse .?
A: Standard sizes (sɛ nhwɛso no, 2400x1200mm) wɔ hɔ a wobetumi anya afi stock mu; Custom sizes hwehwɛ tɔn 50, a sampling a wontua hwee ma qualification testing.
Asɛmmisa: Sɛnea wobɛhwɛ coating adhesion wɔ hot-rolled mprɛte so .?
A: Yɛ cross-cut test (ASTM D3359): Ɛsɛ sɛ SGCC coating kyerɛ ≤5% flaking wɔ 1mm grid cuts akyi, a ɛkyerɛ sɛ adhesion a ɛkyɛn so wɔ hot-rolled substrate no so.
