EN 10025 S355 Chitsulo ndi kalasi yachitsulo yaku Europe, malinga ndi EN 10025-2: 2004, zinthu za S355 zimagawidwa m'makalasi anayi apamwamba:
● S355JR (1.0045)
● S355J0 (1.0553)
● S355J2 (1.0577)
● S355K2 (1.0596)
The katundu structural zitsulo S355 ndi bwino kuposa zitsulo S235 ndi S275 mu zokolola mphamvu ndi kumakoka mphamvu.

Chitsulo Kalasi S355 Tanthauzo (Mapangidwe)

Malembo ndi manambala otsatirawa akufotokoza tanthauzo la kalasi yachitsulo S355.
"S" ndi chidule cha "zitsulo zomangamanga".
"355" amatanthauza minumum zokolola mphamvu mtengo kwa lathyathyathya ndi yaitali chitsulo makulidwe ≤ 16mm.
"JR" amatanthauza mphamvu ya mphamvu ndi minumum 27 J pa kutentha kwa chipinda (20 ℃).
"J0" imatha kupirira mphamvu yamphamvu yosachepera 27 J pa 0 ℃.
"J2" yokhudzana ndi mphamvu yocheperako ndi 27 J pa -20 ℃.
"K2" imatanthawuza kuchepa kwa mphamvu yamphamvu ndi 40 J pa -20 ℃.
