P355N birta

Markabka cadaadiska P335N saxan bir ah ayaa lahaan jiray dhibicda ugu yar ee soo saarista 355 Mpa dhumucda ka hooseysa 16mm. Gnee steel wuxuu awoodaa inuu bixiyo dhumucda saxanka birta ee P355N inta u dhaxaysa 6mm-300mm si loo dammaanad qaado hantida birta ee ka kooban kiimikada iyo hantida farsamada. Waqtiga gaarsiinta ee 1000 tons dalbashada p355n taarikada birta ah, waqtigayaga duubista guud waa inuu ahaadaa 30 maalmood gudahood.
