Incazelo emfushane:


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Ukuphela kokugcina ikakhulukazi ukulandela i-AASHTO M180, GB-T 31439.1-2015 ne-EN1317 ejwayelekile.
Okokusebenza kwalokhu ikakhulukazi i-Q235B (S235Jr amandla wokuvuna angaphezulu kuka-235Mpa) ne-Q345B (S355Jr amandla wokukhiqiza angaphezu kuka-345Mpa).
Ngobukhulu besiphetho sokugcina ikakhulukazi nge-2.5mm kuye ku-4.0mm noma landela okufunwa ngamakhasimende.
Ukwelashwa kwendawo kushisiwe kwafakwa ngosawoti, ukulandela i-AASHTO M232 nezinga elilinganayo njenge-AASHTO M111, EN1461 njll.
Isiphetho sokugcina sigxile ekuqaleni nasekupheleni komgwaqo. Ingavikela abantu ngepuleti yensimbi egobile, ukwehlisa ukulimala okusuka kugrafu.
