FAQ .
Asɛmmisa: Ɔkwan bɛn so na hot-dip galvanizing de toto electro-galvanizing ho .?
A: Hot-dip ma ade a ɛyɛ den, a ɛyɛ den a ɛyɛ den (30-275g/m²) ma wɔde di dwuma wɔ abɔnten; Electro-galvanizing (10-20g/m²) yɛ teateaa na ɛfata sɛ wɔde siesie dan mu te sɛ nneɛma a wɔde yɛ dan mu nneɛma.
Asɛmmisa: So wobetumi de saa coil yi adi dwuma ama nsu a wɔnom a wɔkora so .?
A: Dabi, nsu a wɔnom ho nkitahodi tẽẽ hwehwɛ nneɛma a wɔde yɛ aduan te sɛ dade a ɛnyɛ den anaa dade a wɔde epoxy ayɛ; GI Steel fata ma nsuo a ɛnyɛ nsuo a wɔde gu mu ne nsuo a wɔde gugu nnɔbaeɛ so.
Asɛmmisa: Dɛn ne ɔkwan a eye sen biara a wobɛfa so ayi owiyammo nsenia afi hɔ ansa na woayɛ mfonini .?
A: Fa abrasive blasting (anhwea/shot blasting) di dwuma na ama woanya SA2.5 surface profile, ahwɛ ahu sɛ paint adhesion a eye sen biara ma bere tenten akyɛ.
