ʻO DIN 17100 St52.3 nā paipu kila hoʻokalakupua i hoʻouna ʻia i Australia.
Hoʻohana maʻamau ʻo DIN 17100 i nā ʻāpana kila, nā pahu kila, nā kaula uea, nā huahana pālahalahaholoʻokoʻaa welded, huinahalike a me rectangular hollow pauku, forgings, a me ka semi-hoʻopau huahana i loko o ka laulā structural kila i haawiia ma ka wela hana a normalized kūlana ma hope o hana.
ʻO St52.3 kekahi o nā māka, a ʻo ka helu waiwai ʻo 1.0570.
Ma mua o ka hoʻouna ʻana, hoʻonohonoho ʻo Botop i nā limahana ʻoihana e nānā pono i nā huahana e hōʻoia i ka hoʻokō pono ʻana o ka huahana i nā koi o ka mea kūʻai aku.
ʻO ka mea mua, nānā pono ʻia ka maikaʻi o ka ʻili, ka laulā, ke kiʻekiʻe, ka lōʻihi, ka squareness, a me nā ʻano hiʻohiʻona ʻē aʻe o ka paipu kila e hōʻoia i ka hoʻokō ʻana i nā kūlana a me nā koi o ka mea kūʻai aku.
A laila, nānā ʻia nā waiwai kemika a me nā mechanical o ka paipu kila.

Ma hope o ka hoʻopau ʻana i nā nānā āpau a me ka hōʻoia ʻana e hoʻokō ka maikaʻi i nā koi maʻamau, hoʻopuka ʻia kahi palapala hōʻoia Material (MTC). Ma hope mai, hana ʻia nā hoʻonohonoho no ka hoʻouna ʻana a me nā hana pili.
Mai kona hoʻokumu ʻana i ka makahiki 2014, ua lilo ʻo Botop Steel i mea hoʻolako alakaʻi i nā paipu kila kalapona ma ka ʻākau o Kina, i ʻike ʻia no kāna lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā piha.
No kēlā me kēia kauoha, pili mau ʻo Botop i ka hoʻolālā o ka maikaʻi kūpono a me nā kumukūʻai maikaʻi, e koho ana iā mākou e hāʻawi iā ʻoe i nā huahana paipu kila.
