P1: Mahlasedi a EN 10025 S420 H ke eng?
K: Boreledi ba tšepe bo nang le matla a maholo bo nang le matla a tlhahiso a 420 MPa, bakeng sa mosebetsi o boima oa kaho o kang marokho, mehaho ea indasteri, mehaho e meholo ea span, jj.
P2: Ke boholo bofe bo fumanehang?
A: S420 H Beam e tletse letoto la HEA, HEB le HEM, botebong ba eona bo tloha ho 100 mm ho isa ho 1200 mm. Bolelele bo ikhethileng bo boetse bo fumaneha bakeng sa ho seha.
P3: Na e ka tjheselletsoa kapa ea etsoa ka mochini?
K: E. S420 e ka tjheselletsoa ka botlalo le ho tjheselletsoa ka mechini. Bakeng sa mahlasedi a teteaneng, ho hlokahala ho futhumatsa pele le electrode e nepahetseng ea ho tjheseletsa.
P4: U ka li paka joang bakeng sa ho romelloa?
K: Libalaka li koahetsoe ka ho thibela mafome, li tlameletsoe fatše kapa li tlameletsoe ka lebanta la tšepe le matla a holimo 'me sephutheloana se entsoe ka lepolanka ke khetho.
P5: Ke mekhoa efe ea ho romella e fumanehang?
K: Thomello ea likepe, terene, litsela e fumaneha ho latela bongata ba hau le moo u eang teng.
