Ntau qhov ntau thiab tsawg yog muaj thiab tuaj yeem kho raws li xav tau.

2. Phab ntsa Thickness

Ntau yam: 0.8mm txog 5.0mm.

Feem ntau hu ua colloquially los ntawm thickness, piv txwv li, "1.2 tuab", "2.0 tuab", "3.0 tuab".

Qhov sib txawv tseem ceeb ntawmNational Standard (GB)thiabTsis yog -Standard (Market Standard)cov hlab ntsha nyob hauv phab ntsa tuab. GB raj muaj tag nrho, lav phab ntsa thickness thiab siab dua load-cov kabmob muaj peev xwm; tsis yog- cov raj txheej txheem feem ntau muaj cov phab ntsa tuab tsawg dua li tus nqi nominal thiab qis dua tus nqi.

3. Khoom siv

Q235: Feem ntau siv cov pa roj carbon monoxide zoo tib yam, muab lub zog zoo thiab weldability, haum rau feem ntau cov qauv.

Q195: Tsawg zog me ntsis, siv rau cov qauv me me.

Q345: Siab-lub zog qis- alloy steel, siv rau cov ntawv thov uas xav tau ntau dua load-cov kabmob muaj peev xwm.

Zinc Txheej: Muab faib ua electro-galvanized (txias galvanized) thiab kub-dip galvanized.

Kub-Dip Galvanized Square Tube: Thick zinc layer (usually >60μm), zoo heev corrosion kuj, tuaj yeem nyob 20-50 xyoo sab nraum zoov. Qhov saum npoo muaj tus qauv spangle thiab yog me ntsis ntxhib.

Electro- Galvanized Square Tube: Nyias zinc txheej, du thiab aesthetically pleasing nto, tab sis tsis muaj zog corrosion kuj, feem ntau yog siv rau sab hauv tsev qhuav ib puag ncig.

Ntev

Feem ntau 6 meters ib thooj, tuaj yeem ua kev cai - txiav kom ntev.

1. "Fabricated ces Galvanized" Tube

Txheej txheem: Cov ntawv hlau / sawb yog thawj zaug txias- tsim thiab welded rau hauv ib lub raj square, ces tag nrho cov raj tau kub -dip galvanizing.

Qhov zoo: Uniform zinc txheej ntawm ob sab hauv thiab sab nrauv phab ntsa, muab kev tiv thaiv corrosion zoo. Tshwj xeeb tshaj yog haum rau cov qauv raug rau qhov chaw ntub dej.

Qhov tsis zoo: Zinc dross tuaj yeem tsim ntawm lub vuam seam thaum galvanizing, uas tuaj yeem cuam tshuam qhov tseeb rau qee yam kev sib txuas.

2. "Galvanized ces Fabricated" Tube

Txheej txheem: Siv ua ntej -galvanized steel ntawv / sawb, uas yog ncaj qha txias- tsim thiab welded rau hauv cov duab.

Qhov zoo: Smooth, aesthetically pleasing nto, saj zawg zog ntau lawm, haum rau nyias - cov hlab ntsa.

Qhov tsis zoo: Lub vuam seam tsis muaj zinc txheej tiv thaiv, ua rau nws qhov tsis muaj zog rau corrosion. Rusting feem ntau pib ntawm qhov vuam.

1. Kev Tsim Kho & Cov Qauv Hlau (Kev Lag Luam Loj tshaj plaws)

Primary Steel Structure: Kem, kab teeb, purlins rau lub teeb yuag factories, warehouses, logistics centers, ua liaj ua teb kev lag luam.

Enclosure & Kho kom zoo nkauj: Phab ntsa studs rau lub tsev sab nrauv, ru tsev txhawb nqa, canopy thav duab, sam thiaj railings, stair handrails, ruaj ntseg qhov rais grilles, louvre qhov rais thav ntawv.

Cov chaw tsim kho: Scaffolding (cov khoom tseem ceeb ntawm cuplock scaffolding), kev tsim kho guardrails, kev txhawb nqa ib ntus.

2. Infrastructure & Municipal Engineering

Txoj Kev Pabcuam: Cov ntawv qhia tsheb, cov ncej teeb pom kev zoo, cov neeg saib xyuas, cov ncej thaiv.

Municipal Facilities: Lub moj khaum rau cov chaw tos tsheb npav, cov chaw tsheb kauj vab pej xeem, chaw nres tsheb pov tseg, cov chaw tos txais xov tooj.

Telecommunications & Fais fab: Yooj yim teeb liab yees, cable tais, utility ncej.

3. Machinery Manufacturing & Industrial Equipment

Cov khoom ntas: Ncej thiab kev tiv thaiv npog rau ntau yam cuab yeej siv tshuab, conveyors, cov cuab yeej siv hluav taws xob, cov kab ntau lawm ua haujlwm, cov khoom siv tshuaj xyuas.

Cia & Logistics: Heavy- lub luag haujlwm racking, cov khoom txee, cov tawb cia, pallet taw.

Agricultural Greenhouses: Lub luag haujlwm tseem ceeb thiab theem nrab rau niaj hnub ua liaj ua teb tsev cog khoom, muab kev tiv thaiv corrosion zoo.

4. Rooj tog hauv tsev & siv txhua hnub

Sab nraum zoov rooj tog: Ncej rau cov chaw ua si, cov rooj zaum puam, patio rooj thiab cov rooj zaum, viav vias.

Rooj tog hauv tsev: Muaj-style phau ntawv txee, racks, TV sawv, rooj ceg, txaj ncej.

Zaub Props: Lub moj khaum rau lub khw muag khoom, cov khoom muag muag, kev txhawb nqa racks.

5. Lwm qhov chaw tshwj xeeb

Automotive Kev Lag Luam: Txhawb nqa cov qauv hauv lub tsheb, cov khoom siv chassis.

Nkoj Cabins: Kev them nyiaj yug cov qauv rau sab hauv partitions thiab rooj tog (yuav tsum tau tshwj xeeb marine-qib galvanized raj).

1. Txhais qhov kev siv ib puag ncig:

Sab nraum zoov, ntub, plua plav ib puag ncig: Yuav tsum sivkub-dip galvanized square tubes, thiab cov tuab zinc txheej, qhov zoo dua.

Hauv tsev qhuav ib puag ncig: Electro-galvanized square tubes los yog pheej yig dua dub steel hlab (tsis muaj galvanized, yuav tsum tau pleev xim rau kev tiv thaiv xeb) tuaj yeem siv.

2. Load-Bearing & Safety:

Rau kev thauj khoom-cov kabmob (piv txwv li, racking, shed beams), ua tib zoo saib xyuasphab ntsa thicknessthiabkhoom siv zog. Ua ntej National Standard (GB) hlab thiab ua cov kev suav cov tshuab.

Rau qhov tsis yog -load- bearing lub hom phiaj zoo nkauj (xws li, luas), nyias- cov phab ntsa phab ntsa tuaj yeem xaiv kom txuag nqi.

3. Kev ua haujlwm yuav tsum tau ua:

Yog tias qhov tseem ceeb vuam yuav tsum tau tom qab, nco ntsoov tias cov zinc txheej emits cov pa phem ntawm qhov kub thiab txias. Ua haujlwm hauv qhov dej - qhov cua, thiab siv tshuaj tiv thaiv - cov xim pleev xim rau cov welded seams tom qab.

Rau siab -kev sib dhos precision, nco ntsoov tias kub-dip galvanized hlab yuav muaj me ntsis deformation los yog tsis sib xws zinc txheej.
