Product Overview
Cov kav dej dub square, feem ntau yog xa mus rau cov kav hlau square uas tau kho galvanization, muaj npe rau lawv cov xim dub (lossis grey tsaus, cov xim tshwj xeeb yuav txawv nyob ntawm cov txheej txheem galvanization thiab kev kho mob tom ntej) nto thiab square cross-section. Cov kav dej no tau siv dav hauv ntau yam xws li kev tsim kho, kev tsim khoom siv tshuab, thiab chaw thauj mus los.
Kev tsim khoom
Peb cov yeeb nkab dub square ntau lawm ua raws li 6-kauj ruam precision txheej txheem:
Raw Material Xaiv:High -cov pa roj carbon steel coils (Q235, Q345, thiab lwm yam) raug tshuaj xyuas rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.
Tsim & Vuam: Cov hlau coils tau dov rau hauv cov duab plaub los ntawm kev ua kom txias, tom qab ntawd welded siv siab - zaus induction vuam rau cov pob qij txha muaj zog.
Sizing & Txiav: Cov kav dej yog txiav rau qhov ntev (6m, 12m) lossis kev cai ntau thiab tsawg nrog laser txiav tshuab.
Kev kho mob Blackening:Cov kav dej kub kub-dub dub oxide txheej los txhim kho corrosion kuj thiab deg hardness.
Kev soj ntsuam zoo:Txhua lub yeeb nkab raug kuaj xyuas qhov tseeb qhov tseeb, qhov vuam lub zog, thiab txheej adhesion siv ultrasonic thiab kev ntsuas siab.
Ntim & Cia:Cov kav dej tsim nyog tau ntim rau hauv cov thawv ntoo lossis cov pob khoom, khaws cia hauv cov dej noo-tswj lub tsev khaws khoom kom tsis txhob muaj kev puas tsuaj.
Standards & Certification
ASTM A53 / A53M: Tus qauv ntawm American Society for Testing Materials, teev tias qhov nruab nrab qhov nruab nrab tuab ntawm cov txheej txheej galvanized yuav tsum yog 85 μm (Qib G90), muaj feem xyuam rau cov khoom siv qis - kev thauj mus los ntawm cov kua dej.
ISO 1461: Lub Koom Haum Thoob Ntiaj Teb rau Cov Qauv Txheej Txheem, xav kom cov tuab ntawm cov txheej txheej galvanized txuas nrog cov tuab ntawm cov khoom siv hauv paus (piv txwv li, 1.5 hli cov khoom siv hauv paus sib haum rau 45 μm txheej).
Cov ntsiab lus tseem ceeb thiab kev xeem yuav tsum tau ua
Qhov qis txheej tuab ntawm kub-dip galvanized square kav feem ntau yog 45 μm (raws li ISO 1461) lossis 70 μm (raws li GB / T 3091), thaum cov electro- galvanized square kav yog nyias (kwv yees li 5 - 15 μm).
Txoj Kev Ntsuas: Nws tuaj yeem txheeb xyuas tau siv lub ntsuas qhov sib nqus tuab lossis zinc txheej txheej hnyav (xws li GB / T 13912-2020).
Dimensions thiab Tolerances
Qhov tso cai sib txawv ntawm sab ntev ntawm lub raj square feem ntau yog ± 0.5 hli (raws li GB / T 6728), thiab phab ntsa thickness sib txawv yuav tsum tsis pub tshaj ± 10% 40mm × 40mm square raj. Tus nqi ntsuas tiag tiag yuav tsum nyob hauv thaj tsam ntawm 39.5 - 40.5mm.

Versatility hauv Kev Tsim thiab Kev Siv
Cov kav dej dub square muaj ntau yam zoo kawg nkaus vim lawv cov ntoo khaub lig sib xws -sectional shape thiab straightforward fabrication process. Lawv cov square geometry tso cai rau kom yooj yim stacking, haum, thiab vuam, ua rau lawv zoo meej rau kev siv ntau yam kev tsim kho thiab kev lag luam. Qee cov ntawv thov tseem ceeb suav nrog:
Kev siv tus qauv: Cov kav dej dub square yog siv dav hauv kev tsim cov thav duab, kev txhawb nqa, thiab kab hauv cov tsev, txuas hniav, thiab lwm yam kev tsim vaj tsev. Lawv lub zog thiab kev yooj yim ntawm kev siv vuam ua rau lawv zoo tagnrho rau kev tsim cov qauv ruaj khov.
Furniture Manufacturing: Vim lawv qhov zoo nkauj zoo nkauj thiab yooj yim ntawm kev tuav, cov kav dej dub square kuj tseem siv rau hauv kev tsim cov rooj tog, tshwj xeeb tshaj yog nyob rau hauv kev lag luam - cov rooj tog zaum qhov twg raw, unpolished tiav yog txaus siab rau.
Kev thauj mus los: Cov kav dej no yog siv rau hauv kev tsim cov tsheb thav duab, tsheb thauj khoom, thiab lwm yam khoom siv thauj khoom vim lawv muaj peev xwm tiv taus cov khoom hnyav thiab siab.
Agricultural Applications: Cov kav dej dub kuj tseem siv rau hauv cov khoom siv ua liaj ua teb xws li laj kab, rooj vag, thiab cov khoom siv tshuab, muab kev txhawb nqa ntev ntev - nyob rau hauv qhov nyuaj sab nraum zoov.
Khoom zoo
Cov khoom siv tseem ceeb siv rau cov kav dej dub yog carbon steel, uas paub txog nws lub zog tensile siab thiab robustness. Cov kav dej no muaj cov khoom siv kho tshuab zoo heev, ua rau lawv muaj peev xwm tiv taus cov khoom hnyav thiab hnyav hnyav yam tsis ua haujlwm. Qhov no ua rau cov kav dej dub zoo tagnrho rau kev siv cov qauv uas muaj zog thiab ua haujlwm ntev yog qhov tseem ceeb, xws li hauv tsev thav duab, scaffolding, thiab kev txhawb nqa kab.
Cov ntsiab lus carbon hauv cov hlau ua rau cov yeeb nkab muaj zog thiab rigidity, txawm hais tias nws kuj tseem tuaj yeem ua rau cov yeeb nkab muaj kev cuam tshuam rau corrosion nyob rau hauv qee yam kev mob. Txhawm rau tiv thaiv qhov no, cov kav dej square dub feem ntau yog coated nrog cov tshuaj tiv thaiv -corrosive finishes los yog pleev xim rau kom ntev lawv lifespan nyob rau hauv sab nraum zoov los yog hnyav ib puag ncig.
Thaum cov kav dej dub square muaj qhov tsis zoo rau kev xeb vim lawv cov hlau muaj pes tsawg leeg, lawv tsis muaj zog li galvanized lossis stainless hlau kav. Qhov "dub" tiav yog hais txog lub ntuj oxidation uas tshwm sim thaum lub sijhawm tsim khoom, uas tuaj yeem tiv thaiv cov yeeb nkab rau lub sijhawm txwv tab sis yuav tsis muab sijhawm ntev - tiv thaiv xeb lossis xeb. Nyob rau hauv cov cheeb tsam uas muaj dej noo los yog raug tshuaj lom neeg, nws yog advisable siv dub square kav nrog tiv thaiv txheej los yog opt rau stainless hlau kom zoo corrosion kuj.
