Inde, EN 10210 =BS EN 10210.
BS EN 10210 ndi EN 10210 ndizofanana muukadaulo ndipo zonse zikuyimira miyezo ya ku Europe ya kapangidwe, kapangidwe, ndi zofunikira za magawo obowoka omwe amapangidwa ndi thermoformed.
BS EN 10210 ndiye mtundu womwe unagwiritsidwa ntchito ku UK, pomwe EN 10210 ndi muyezo wa ku Europe konse. Mabungwe osiyanasiyana okhazikitsa miyezo ya dziko akhoza kuyambitsa muyezo ndi mawu ofupikitsa a dziko, koma zomwe zili mu muyezowo zimakhalabe zofanana.
Magawo opanda kanthu amatha kugawidwa m'magulu ozungulira, amakona anayi kapena amakona anayi, kapena ozungulira.
Komanso chifukwa ndi njira yotentha yomalizidwa motsatira EN 10210, chidule chotsatirachi chingagwiritsidwe ntchito.
HFCHS= magawo otentha ozungulira opanda kanthu;
HFRHS= magawo otentha omalizidwa a sikweya kapena amakona anayi opanda kanthu;
HFEHS= magawo otentha opangidwa ndi elliptical hollow.
Chozungulira: M'mimba mwake wakunja mpaka 2500 mm;
Makoma okwana mpaka 120 mm.
Zachidziwikire, palibe njira yopangira machubu a kukula kotere ndi makulidwe a khoma ngati njira yolumikizira ERW ikugwiritsidwa ntchito.
ERW imatha kupanga machubu okwana 660mm okhala ndi makulidwe a khoma a 20mm.
Chitsulo chingapangidwe kudzera muwopanda msoko kapena wowotchereranjira.
Pakati panjira zowotcherera, njira zodziwika bwino zowotcherera zimaphatikizapoERW(kuwotcherera kwa magetsi) ndiSAW(kuwotcherera kwa arc m'madzi).
Pakati pa ena,ERWndi njira yolumikizira zitsulo yomwe imagwirizanitsa zitsulo pogwiritsa ntchito kutentha ndi kupanikizika kolimba. Njirayi imagwiritsidwa ntchito pazinthu zosiyanasiyana komanso makulidwe ndipo imalola njira yolumikizira zitsulo bwino.
SAWKumbali inayi, ndi njira yowotcherera yomwe imagwiritsa ntchito granular flux kuphimba arc, yomwe imapereka kulowa mozama komanso ubwino wabwino wa weld ndipo ndi yoyenera kwambiri pa ma plate okhuthala.
Chotsatira, ndi njira ya ERW, yomwe ndi njira yopangira yogwira mtima kwambiri yomwe imagwiritsidwa ntchito kwambiri popanga machubu ndi ma profiles osiyanasiyana achitsulo.
Tiyenera kudziwa kuti pazigawo zosagwiritsidwa ntchito bwino komanso zopanda kanthu zopangidwa ndi njira yolumikizira, ma weld okonzanso saloledwa kupatulapo ma weld olowa pansi pa nthaka.
Makhalidwe JR, JO, J2 ndi K2 - yomalizidwa bwino,
Mphamvu yocheperako ya chitoliro chachitsulo cha S355J2H si yokhazikika, idzasintha ndi makulidwe osiyanasiyana a khoma.
Makamaka, mphamvu yopezera mphamvu ya S355J2H imakhazikitsidwa molingana ndi muyezo pamene makulidwe a khoma ndi ochepera kapena ofanana ndi 16mm, koma makulidwe a khoma akawonjezeka, mphamvu yopezera mphamvu idzachepa, kotero si mapaipi onse achitsulo a S355J2H omwe angafikire mphamvu yopezera mphamvu yocheperako ya 355MPa.

Chitoliro chachitsulo cha S355J2H ndi chitoliro chachitsulo champhamvu kwambiri chomwe chimagwira ntchito bwino powotcherera komanso kulimba kwa kutentha kochepa, kotero chimagwiritsidwa ntchito m'mafakitale osiyanasiyana.
1. Kapangidwe ka nyumba: amagwiritsidwa ntchito pa milatho, nsanja, mafelemu, mayendedwe a sitima, sitima zapansi panthaka, mafelemu a denga, makoma, ndi nyumba zina zomangira.
2. Dongosolo la mapaipi: Amagwiritsidwa ntchito ngati mapaipi onyamulira madzi, makamaka nthawi zomwe mphamvu ndi kukana kuthamanga kumafunika.
3. Uinjiniya wa m'madzi ndi m'mphepete mwa nyanja: amagwiritsidwa ntchito m'mapangidwe a zombo, mapulatifomu a m'mphepete mwa nyanja, ndi nyumba zina zaukadaulo wapamadzi.
4. Makampani amagetsi: amagwiritsidwa ntchito m'malo opangira mphamvu monga nsanja zamphamvu za mphepo, nsanja zobowolera mafuta, ndi mapaipi.
5. Mitsempha yothamanga: imagwiritsidwa ntchito popanga ziwiya zopondereza mogwirizana ndi zofunikira zinazake zowotcherera ndi zotenthetsera.
6. Makampani a migodi: amagwiritsidwa ntchito popanga zigawo za zomangamanga zothandizira mgodi, makina otumizira, ndi zida zogwiritsira ntchito miyala.
