Yog lawm, cov raj square yog qhov tsim nyog rau kev tsim kho, muab kev sib xyaw ua ke ntawm cov qauv siv zog, tsim qauv yooj yim, thiab tus nqi - ua tau zoo. Lawv tau dav siv nyob rau hauv lub moj khaum, kev txhawb nqa, thiab cov khoom zoo nkauj thoob plaws hauv vaj tse, kev lag luam, thiab kev lag luam. Hauv qab no yog cov ncauj lus kom ntxaws txog lawv qhov kev tsim nyog, kev siv, thiab cov ntsiab lus tseem ceeb:
1. Qhov zoo ntawm Square Tubes hauv kev tsim kho
A. Lub zog muaj zog & ruaj khov
Uniform Load Distribution: Square cross-sections tiv thaiv dabtsi yog khoov thiab torsion zoo dua cov hlab puag ncig hauv qee qhov kev taw qhia, ua rau lawv zoo tagnrho rau kev thauj khoom-cov kabmob (piv txwv li, ru tsev trusses, scaffolding).
Lub zog siab -rau- Qhov Ntsuas Qhov Ntsuas: Cov pa roj carbon steel square raj (piv txwv li, Q235B, Q355B) muab lub zog tseem ceeb nrog kev siv cov khoom siv tsawg, txo qhov hnyav ntawm cov qauv thiab cov nqi hauv paus.
Customizable Thickness: Phab ntsa thickness (piv txwv li, 2mm-6mm) tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb, los ntawm lub teeb -cov dej num faib mus rau hnyav- lub luag haujlwm beams.
B. Tsim Flexibility
Aesthetic Appeal: Cov kab huv huv thiab cov kaum sab xis ua kom yooj yim sib txuas thiab tsim cov qauv niaj hnub, geometric tsim rau facades, railings, thiab canopies.
Yooj yim ntawm Fabrication: Square tubes yooj yim dua rau kev txiav, vuam, thiab laum piv rau cov raj puag ncig, txo cov nqi zog thiab siv sijhawm.
Kev Tsim Kho Modular: Cov qauv tsim (piv txwv li, 40 × 40mm, 60 × 60mm) pab kom prefabrication thiab ceev sib dhos ntawm cov qauv tsim xws li cov tsev nyob ib ntus lossis cov chaw ua yeeb yam.
C. Tus nqi -Kev ua tau zoo
Khoom Siv Tau Zoo: Tsawg pov tseg thaum txiav piv rau I- kab teeb lossis kaum.
Tus nqi thauj khoom qis dua: Hollow tsim txo qhov hnyav piv rau cov khoom tuav, txiav cov nqi thauj khoom.
Lub neej ntev: Thaum kho (piv txwv li, galvanized, pleev xim), cov raj square tiv thaiv corrosion, txo cov nqi tu thiab hloov cov nqi tshaj lub tsev lub neej.

3. Phau ntawv qhia txog kev xaiv khoom
A. Carbon Steel (Q235B, Q355B)
Qhov zoo tshaj plaws rau: Load-cov kabmob cov qauv hauv qhov chaw qhuav lossis ib puag ncig ntub.
Kev kho mob: Kub-dip galvanizing (rau siv sab nraum zoov) lossis xim txheej (rau siv sab hauv tsev).
Tus nqi: Tsawg rau nruab nrab (piv txwv li, 500–1,200 / tuj rau Q235B).
B. Stainless hlau (304, 316L)
Qhov zoo tshaj plaws rau: ntug hiav txwv dej, tshuaj lom neeg, lossis zaub mov- cov chaw ua haujlwm uas muaj kev tiv thaiv corrosion tseem ceeb.
Qib Xaiv:
304: Kev siv sab nraum zoov.
316L: Marine ib puag ncig (tsim tshuaj tiv thaiv).
Tus nqi: Siab (piv txwv li, 2,500–4,000 / tuj rau 316L).
C. Aluminium Alloy (6061, 6063)
Qhov zoo tshaj plaws rau: Lub teeb yuag, tsis yog - daim ntaub ntawv corrosive (xws li, canopies, sab hauv partitions).
Kev kho mob: Anodizing (rau durability) los yog hmoov txheej (rau xim xaiv).
Tus nqi: Nruab nrab mus rau siab (piv txwv li, 2,800–3,500 / tuj rau 6063-T5).
4. Kev txiav txim siab tsim qauv tseem ceeb
A. Load-Bearing Capacity
Xam Deflection: Siv engineering software (piv txwv li, STAAD.Pro) kom ntseeg tau tias cov hlab yuav tsis sag hauv load.
Piv txwv li: A 60 × 60 × 3mm Q355B raj tuaj yeem ncav cuag 4m nrog lub ntsiab lus ntawm 500kg yam tsis muaj qhov deflection ntau dhau.
B. Txoj kev sib txuas
Vuam: Muaj zog tshaj tab sis yuav tsum tau ua haujlwm txawj; haum rau cov qauv ruaj khov.
Bolting / Clamping: Kev sib dhos ceev dua; zoo tagnrho rau modular los yog ib ntus tsim.
Bracing: Ntxiv cov tswv cuab kab pheeb ces kaum los txhim kho kev ruaj ntseg hauv cov qauv siab lossis dav.
C. Environmental Factors
Corrosion: Nyob rau hauv ntug dej hiav txwv, tsis txhob carbon steel tshwj tsis yog galvanized los yog pleev xim rau; xaiv rau stainless hlau los yog aluminium.
Kev Tiv Thaiv Hluav Taws Xob: Cov pa roj carbon steel khaws lub zog ntawm qhov kub siab (txog 500 degree), thaum aluminium melts ntawm ~ 660℃(siv hluav taws- cov txheej tiv thaiv yog tias xav tau).
5. Kev Tshawb Fawb Kev Lag Luam
Singapore's Marina Bay Sands SkyPark: Siv 100 × 100 × 6mm stainless hlau square tubes rau nws cov qauv cantilevered iconic, tiv thaiv cua loads thiab corrosion nyob rau hauv ib qho chaw sov.
IKEA's Modular Stores: Siv txhuas square tubes (60 × 60 × 3mm) rau sab hauv partitions, ua kom ceev reconfiguration thaum lub sij hawm kho dua tshiab.
Dubai's Solar Park: Tsim los nrog kub-dip galvanized Q355B square tubes (80 × 80 × 4mm) rau hnub ci vaj huam sib luag txhawb nqa thav duab, tiv thaiv cov xuab zeb thiab cua sov.
Xaus
Square tubes zoo tagnrho rau kev tsim kho thaum:
Daim ntawv thov yuav tsum muaj qhov sib npaug ntawm lub zog, qhov hnyav, thiab tus nqi (piv txwv li, ncej, railings).
Tus tsim hu rau cov kab huv huv lossis kev sib dhos modular (xws li, facades, cov qauv ib ntus).
Ib puag ncig yog suav nrog (piv txwv li, galvanized steel rau av noo, stainless hlau rau ntsev tsuag).
Txhawm rau kom tau txais txiaj ntsig zoo, koom tes nrog tus kws tsim qauv tsim qauv los xaiv cov khoom tsim nyog, qhov loj me, thiab txoj kev sib txuas rau koj qhov project. Cov pa roj carbon steel square raj yog ntau yam thiab tus nqi ntau tshaj - kev xaiv zoo rau feem ntau cov ntawv thov, thaum stainless hlau los yog aluminium excel nyob rau hauv tshwj xeeb los yog siab -corrosion ib puag ncig.
