Hais txog kev xaiv cov khoom siv thiab kev siv peev txheej, niaj hnub steel qauv txhawb nqa feem ntau siv cov pa roj carbon structural steel lossis qis- alloy siab- lub zog steel. Cov txheej txheem ntau lawm yog tsim los txo cov khoom pov tseg; tshwj xeeb, kev txiav thiab fabrication kev ua haujlwm tau ua kom zoo dua los ua kom cov khoom siv tau zoo tshaj plaws, yog li ua tiav kev siv cov peev txheej zoo. Cov khib nyiab thiab offcuts tau rov ua dua tshiab thiab ua tiav, tso cai rau lawv rov qab siv dua thiab rov siv dua, uas txo qis cov peev txheej ntuj.
Environmental sustainability cov hauv paus ntsiab lus tseem muaj kev cuam tshuam hauv kev tsim khoom thiab kev tswj hwm kev siv hluav taws xob. Kev siv cov cuab yeej ua haujlwm siab -cov cuab yeej ua haujlwm tau zoo thiab cov cuab yeej siv vuam tshuab tsis yog tsuas yog txhim kho qhov tseeb thiab zoo, tab sis kuj txo qis kev siv hluav taws xob thiab txo qis cov pa phem. Rau saum npoo los tiv thaiv- kev kho corrosion, qhov tseem ceeb yog muab rau qis -VOC (volatile organic compound) thiab qis- cov pa phem coatings, los yog kub-dip galvanizing txheej txheem, kom txo tau qhov cuam tshuam tsis zoo ntawm huab cua, dej, thiab av, yog li txo qis tag nrho ib puag ncig.
Sustainability tseem yog lub hom phiaj tseem ceeb thaum lub sij hawm ua hauj lwm thiab txij nkawm ntawm steel structural kev txhawb nqa thiab. Cov qauv no yog tsim los ua kom muaj zog thiab ruaj khov, yog li txo qhov kev xav tau ntawm kev hloov thiab kho; Tsis tas li ntawd, lawv cov qauv tsim qauv yooj yim disassembly thiab rov siv dua. Thaum mus txog qhov kawg ntawm lawv lub neej kev pabcuam, cov kev txhawb nqa uas tau muab pov tseg tuaj yeem rov ua dua thiab rov ua dua tshiab, yog li ua kom muaj kev qhia dav dav "tag nrho-kev ua neej nyob" ib puag ncig lub tswv yim uas ua raws li cov hauv paus ntsiab lus ntawm lub tsev ntsuab thiab kev tsim kho kom ruaj khov.
