DIN 17100 St52.3 mapaipi achitsulo amakona anayi adatumizidwa ku Australia.
DIN 17100 ndiyomwe imagwiritsidwa ntchito pazigawo zachitsulo, mipiringidzo yachitsulo, ndodo zamawaya, zinthu zosalalaopanda msokondi ma welded, masikweya ndi amakona anayi a dzenje zigawo, forgings, ndi zinthu theka anamaliza mu zitsulo zonse structural amene amaperekedwa mu otentha opangidwa kapena chikhalidwe normalized pambuyo kupanga.
St52.3 ndi imodzi mwamagiredi, ndipo nambala yazinthu ndi 1.0570.
Asanaperekedwe, Botop imakonzekera akatswiri odziwa bwino ntchito kuti aziyang'ana mosamala zinthuzo kuti awonetsetse kuti malondawo akukwaniritsa zofunikira za kasitomala.
Choyamba, pamwamba khalidwe, m'lifupi, kutalika, kutalika, squareness, ndi maonekedwe ena miyeso ya structural zitsulo chitoliro anaunika mosamala kuonetsetsa kutsatira mfundo ndi zofunika kasitomala.
Kenako, mankhwala ndi makina katundu wa structural zitsulo chitoliro kufufuzidwa.
TS EN 17100 St52.3 ili ndi zofunikira pakupanga mankhwala:

Mankhwala a St52.3 amayezedwa ndi spectrometer, ndipo zonse zomwe zili mkati zimakwaniritsa zofunikira zamakasitomala poyerekeza ndi zomwe zikufunika.
Makina a EN 17100 St52.3 makamaka amaphatikiza mphamvu zamakokedwe ndi zokolola, zomwe zimayesedwa ndi kuyesa kolimba.

Mukamaliza kuyendera zonse ndikuwonetsetsa kuti mtundu wake ukukwaniritsa zofunikira, satifiketi Yoyeserera (MTC) imaperekedwa. Pambuyo pake, zokonzekera zimapangidwira zotumiza ndi ntchito zina.
Chiyambireni kukhazikitsidwa mu 2014, Botop Steel yakhala ikugulitsa mapaipi achitsulo kumpoto kwa China, yomwe imadziwika ndi ntchito zake zabwino kwambiri, zinthu zamtengo wapatali, komanso mayankho athunthu.
Pa dongosolo lililonse, Botop nthawi zonse amatsatira njira yodalirika komanso mitengo yabwino, kutisankha kuti tikupatseni mankhwala odalirika a chitoliro chachitsulo.
