DIN 17100 St52.3 rectangular structural paipa uʻamea na lafoina i Ausetalia.
DIN 17100 o loʻo faʻaaogaina i vaega uʻamea, faʻamau uʻamea, uaea uaea, oloa mafolafolaleai se fa'ailogama uelo, sikuea ma rectangular vaega gaogao, forgings, ma semi-uma oloa i le lautele fausaga uamea lea e tuuina atu i le vevela faia po o normalized tulaga ina ua uma le gaosiga.
St52.3 o se tasi o togi, ma o le meafaitino numera o le 1.0570.
Aʻo leʻi tuʻuina atu, e faʻatulagaina e Botop mo tagata faigaluega faʻapitoa faʻapitoa e asiasia ma le faʻaeteete ia oloa ina ia mautinoa o le lelei o le oloa e fetaui lelei ma manaoga o tagata faatau.
Muamua, o le tulaga maualuga, lautele, maualuga, umi, sikuea, ma isi foliga vaaia o le paipa uamea fausaga e siakiina ma le faaeteete ina ia mautinoa le tausisia o tulaga ma manaoga o tagata faatau.
O le isi, o le vailaʻau ma mea faʻainisinia o le paipa uʻamea fausaga e siaki.
EN 17100 St52.3 o loʻo i ai tulaga manaʻomia o vailaʻau faʻapitoa:

Ole vaila'au ole St52.3 e fuaina ile spectrometer, ma o mea uma ole elemene e fetaui ma mana'oga o tagata fa'atau fa'atusatusa i mana'oga talafeagai.
O mea faʻainisinia o le EN 17100 St52.3 e aofia ai le malosi faʻamalosi ma le malosi e maua ai, lea e fuaina i suʻega faʻamalosi.

A mae'a su'esu'ega uma ma fa'amautinoa o lo'o fetaui lelei le tulaga mana'omia, ona tu'uina atu lea o se Tusi Fa'amaonia o Su'ega Mea (MTC). Mulimuli ane, ua faia fuafuaga mo fela'ua'iga ma galuega fa'atatau.
Talu mai lona faʻavaeina i le 2014, ua avea Botop Steel ma taʻutaʻua faʻatau paipa uʻamea carbon i le itu i matu o Saina, e lauiloa mo lana auaunaga sili, oloa maualuga, ma fofo atoatoa.
Mo faʻatonuga taʻitasi, e faʻapipiʻi pea Botop i le taʻiala o le lelei faʻatuatuaina ma tau lelei, filifilia i matou e tuʻuina atu ia te oe oloa faʻatau paipa uʻamea.
