Mainit na gumulong banayad na bakal na coil

Ang carbon steel ay napakalakas at lumalaban sa pagkabigla. Ginagawa nitong carbon steel coil ang isang tanyag na pagpipilian para sa konstruksyon, piping at suportahan ang mga modernong kalsada. Ang ganitong uri ng carbon steel coil ay hindi rin madaling kapitan ng nabubulok tulad ng maraming iba pang mga metal, tulad ng galvanized steel plate a nd prepainted steel coil. Ligtas -Magkumpara sa maraming iba pang mga materyales, ang bakal ay ligtas na hawakan at magtrabaho.

Ang carbon steel coil ay isang pangunahing uri ng bakal coil.Rolling ay nahahati sa malamig na gumulong at mainit na rolyo na mga sheet ng bakal, at ang temperatura ng recrystallization ay ang pagkakaiba-iba ng punto. Ang hot-roll sheet ay may mahinang katigasan at pagkusot sa ibabaw, at ang presyo ay mababa, habang ang sheet na may malamig na sheet ay may mahusay na kahabaan at katigasan, ngunit ang presyo ay mas mahal. Ang sheet na cold-roll ay malamig na gumulong, at ang ibabaw ay walang balat ng oxide at may mahusay na kalidad. Ang hot-roll sheet ay pinoproseso ng mainit na pag-ikot, at ang ibabaw ay may scale ng oxide .
