Simbi Giredhi S355 Zvinoreva (Designation)
Aya anotevera mabhii nenhamba anotsanangura simbi giredhi S355 zvinoreva.
"S" ipfupi ye "structural steel".
"355" inoreva minumum goho simba ukoshi nokuda flat uye refu simbi ukobvu ≤ 16mm.
"JR" zvinoreva kukosha kwesimba kuri minumum 27 J patembiricha yekamuri (20 ℃).
"J0" inogona kumira simba rekuita kanenge 27 J pa 0 ℃.
"J2" ine chekuita neiyo minumum kukanganisa simba kukosha ndeye 27 J pa -20 ℃.
"K2" inoreva iyo minumum kukanganisa simba kukosha ndeye 40 J pa -20 ℃.
