ASTM A572 Qib 42/50/55/60 Hlau Portal Ncej Qauv rau Warehouse & Workshop
A kev tsim kho ntawm lub portal steel ncejyog ib hom kev tsim kho vaj tse uas feem ntau siv rau hauv kev lag luam, kev lag luam, thiab kev ua liaj ua teb vim nws qhov ceev, yooj yim thiab yoog tau. Nws yog tsim los ntawm ob lub kem (cov tswv cuab ntsug) thiab lub ru tsev kab rov tav lossis nqes hav (rafter) uas txuas nrog ruaj khov ntawm cov pob qij txha ntawm ib theem, tsim ib lub thav duab "portal" uas tuaj yeem tiv taus lub zog sab nraud yam tsis muaj bunkers ntawm kev txhawb nqa nruab nrab txiv neej.
Cov Khoom Siv Qauv
Cov kem — Cov ntsiab lus ntsug uas nqa lub nra ntawm lub ru tsev.
Cov rafters - cov kab nqes los yog kab rov tav uas tsim lub ru tsev pitch.
Cov Phaj Hauv Paus thiab Lub Hauv Paus - Txuas cov kem rau lub hauv paus.
Purlins thiab Girts: - Cov ntsiab lus thib ob uas muab kev txhawb nqa rau lub ru tsev thiab phab ntsa.
Kev Tuav (xaiv tau) - Ntxiv kev ruaj khov ntxiv rau sab kom ntev dua.
Cov txiaj ntsig: qhov dav dav, qhov ceev ntawm kev erection, kev ywj pheej ntawm kev tsim qauv, tus nqi tsim nyog.

Q1: ASTM A572 steel phaj yog dab tsi?
A: ASTM A572 hlau yog lub zog siab, qis alloy (HSLA) cov hlau phaj uas pom cov ntawv thov dav hauv kev tsim kho. 42, 50, 55, thiab 60 qib qhia txog qhov sib txawv tsawg kawg nkaus ntawm cov zis muaj zog (42K, 50K, 55K, thiab 60K feem), uas tuaj yeem xaiv raws li qhov xav tau ntawm cov khoom thauj sib txawv.
Q2: Dab tsi ua rau kev tsim kho lub portal ncej tsim nyog rau kev siv ASTM A572?
A: FortaSteel muaj zog heev, weldability zoo thiab corrosion tsis kam zoo ib yam li ASTM A572. Kev siv rau hauv cov thav duab portal coj qhov zoo ntawm kev pom tseeb ntev dua thiab txo cov hlau siv thiab cov thav duab portal yuav yog qhov tseem ceeb los xyuas kom meej tias cov qauv ruaj khov hauv cov tsev rau khoom thiab cov chaw ua haujlwm.
Q3: Cov ntawv thov feem ntau yog dab tsi?
A: Cov thav duab portal no pom ntau daim ntawv thov xws li:
Cov chaw khaws khoom lag luam thiab cov chaw cia khoom
Cov chaw ua haujlwm rau kev tsim khoom thiab kev tsim khoom
Cov tsev ua liaj ua teb
Cov chaw nres dav hlau thiab cov chaw logistics
Q4: Kuv tuaj yeem mus deb npaum li cas thiab siab npaum li cas?
A: Nyob ntawm qhov xav tau ntawm qhov project thiab kev tsim qauv, cov thav duab aluminium portal nrog A572 steel tuaj yeem muaj qhov ntev txog 10–60 meters (33–197 ft) thiab qhov siab ntawm eave txog li 4–15 meters (13–50 ft).
Q5: Peb puas tuaj yeem kho cov thav duab rau cov kev xav tau tshwj xeeb?
A: Yog. Qhov ntev ntawm kem thiab rafter, qhov siab ntawm lub ru tsev, kev txhawb nqa, phab ntsa thiab ru tsev cladding tuaj yeem hloov kho kom haum rau qhov kev thauj khoom, kev tshem tawm thiab cov lus qhia pom uas txhua qhov project muaj.
Q6: Txoj kev tiv thaiv xeb yog dab tsi?
