Cov khoom muag
Galvanized lub raj yog hollow ntev strips ntawm cov hlau nrog ib lub duab plaub -section. Lawv yog cov txias - ua hollow steel seem. Lawv yog tsim los ntawm sawb hlau thiab tau ua tiav los ntawm kev ntim khoom, flattening, coiling, vuam rau hauv cov raj puag ncig, uas tom qab ntawd dov rau hauv cov duab plaub. Cov txheej txheej zinc txheej tuaj yeem tsim txheej txheej tiv thaiv oxide, thiab lawv tau siv dav los ua cov kav dej rau kev thauj cov kua dej.
Material & Chemical compostion
Cov khoom siv ntawm cov kav dej galvanized tuaj yeem muab faib ua ob pawg: cov pa roj carbon steel thiab cov hlau tsis tshua muaj hlau. Cov qib ntawm cov pa roj carbon monoxide muaj xws li Q195, Q215, Q235 (xws li Q235A, Q235B), SS400, 20 # steel, 45 # steel, thiab lwm yam; Cov qib qis ntawm cov hlau tsis tshua muaj xws li Q345 (xws li Q345A, Q345B, Q345C, Q345D, Q345E), 16Mn, Q390, ST52-3, thiab lwm yam. Ntawm lawv, Q235 thiab Q345 yog cov khoom siv dav tshaj plaws.
Dimensional Range & Tolerances
Qhov ntev kam rau ua raws li GB / T309-201 tus qauv. Qhov tso cai sib txawv ntawm sab ntev yog los ntawm ± 0.5mm txog ± 2.0mm. Lub thickness sib txawv yog tswj nyob rau hauv ± 10%, qhov dabtsi yog khoov℃ib square meter tsis pub tshaj 1.5 hli, thiab cov kab pheeb ces kaum sib txawv ntawm lub square thiab rectangular raj yuav tsum tsawg tshaj li 1.5% ntawm sab ntev.
Cov txheej txheem tsim khoom nruj
Peb cov galvanized square raj mus txog 6 cov kauj ruam tseem ceeb los lav qhov zoo:
Kev xaiv raw khoom: Peb siv cov qib siab -zoo qis- carbon steel coils (Q235 / Q355 qib) nrog cov tshuaj lom neeg ruaj khov, ua kom lub cev muaj zog.
Tsim & Vuam: Steel coils yog txias- ua rau cov duab plaub los ntawm precision rollers, ces welded siv high- zaus induction vuam (HFIW) rau nruj, du pob qij txha.
Deburring & Trimming:Welded hlab yog deburred sab hauv thiab sab nraud, ces txiav mus rau tus qauv lossis kev cai ntev (max 12 meters) nrog laser precision.
Kub-Dip Galvanizing: Cov hlab yog muab tso rau hauv 450℃zinc da dej, tsim 80-120μm tuab zinc txheej-cov kauj ruam no ua kom muaj kev tiv thaiv zoo heev.
Txias & Passivation: Galvanized hlab yog txias sai, tom qab ntawd kho nrog cov tshuaj passivation los txhim kho zinc txheej adhesion thiab tiv thaiv xeb dawb.
Kev soj ntsuam zoo:Txhua lub raj raug kuaj xyuas qhov ntev, ntsuas zinc txheej tuab, thiab ntsuas kev ntsuas siab (rau cov dej xau) ua ntej ntim.
3.Quality Inspection Stage
Tag nrho peb cov khoom raug soj ntsuam nruj thiab tuaj nrogtxhim khu kev qha zoo.
-Geometry-Kev tshuaj xyuas
Lus Askiv Caption: Tshawb xyuas sab ntev, phab ntsa tuab, thiab kab pheeb ces kaum ntawm cov kav dej galvanized nrog cov cuab yeej ntsuas kev ua haujlwm kom ua tau raws li cov qauv thoob ntiaj teb.
-Txheej Thk Test
Lus Askiv Caption: Siv lub ntsuas qhov sib nqus kom pom cov galvanized txheej tuab ntawm cov kav dej, kom ntseeg tau tias muaj kev tiv thaiv zoo thiab tiv thaiv corrosion zoo heev.
-Kev Ntsuas Hydrostatic
Lus Askiv Caption: Ua cov kev ntsuas dej siab ntawm cov kav dej kom paub tseeb tias kev ua haujlwm siab thiab sealing kev ua tau zoo, lav tias muaj kev nyab xeeb rau kev siv dej hauv kev thauj mus los.
3. Cov khoom tseem ceeb ntawm Galvanized Rectangular Tubes
Peb cov galvanized square raj ua tau zoo hauv kev ua tau zoo thiab ntau yam:
Corrosion Resistance:Qhov kub-dip zinc txheej tiv thaiv xeb thiab oxidation, ua rau lawv haum rau sab nraum zoov (xws li, tsev facades, laj kab) thiab qhov chaw ntub dej (xws li, cov tsev cog khoom ua liaj ua teb).
Structural Strength:Nrog phab ntsa thickness xws li 1.2mm mus rau 6mm thiab sab qhov ntau thiab tsawg los ntawm 20 × 40mm mus rau 200 × 300mm, lawv muaj zog load-cov kabmob muaj peev xwm rau cov qauv txheej txheem.
Yooj yim Installation: Smooth nto thiab meej qhov ntev tso cai rau kev sib dhos ceev nrog bolts lossis vuam, txo ntawm - lub sijhawm tsim kho.
Ntev Lifespan:Raws li kev siv ib txwm, cov hlab ntsha muaj lub neej kev pab ntawm 15-20 xyoo, txo cov nqi kho thiab hloov pauv rau cov neeg siv khoom.
Vim li cas thiaj xaiv peb rau Galvanized Square Pipes?
Peb yog cov chaw tsim khoom tshwj xeeb hauv galvanized square raj, nrog ntau tshaj 10 xyoo ntawm kev paub hauv steel khoom tsim. Peb 50,000-square- 'meter' ntau lawm puag yog nruab nrog 8 cov kab ntau lawm, ua kom muaj txiaj ntsig txhua xyoo ntawm 80,000 tons- muaj peev xwm ua tau raws li qhov loj - ntim xaj los ntawm cov neeg siv khoom thoob ntiaj teb (xws li cov tuam txhab tsim kho, cov khoom muag khoom muag). Peb tuav ISO 9001 daim ntawv pov thawj zoo thiab ua raws li ASTM, EN, thiab GB cov qauv, ua kom txhua pawg ntawm cov khoom ua tau raws li cov kev cai nruj. Raws li cov chaw tsim khoom ncaj qha, peb txiav tawm cov neeg nruab nrab, muab cov nqi sib tw ntawm lub Hoobkas ncaj qha thaum muab cov kev daws teeb meem (xws li, qhov ntau thiab tsawg, thicknesses) kom haum rau qhov kev xav tau tshwj xeeb.
Kev ua tau zoo yog peb qhov tseem ceeb tshaj plaws. Txhua galvanized square yeeb nkab tau raug tshuaj xyuas nruj, los ntawm kev xaiv cov khoom siv raw mus rau kub -dip galvanizing tiav, ua tau raws li cov qauv thoob ntiaj teb rau kev tiv thaiv corrosion, lub zog thiab durability. Qhov koj pom yog qhov koj tau txais - qhov ntev, qhov chaw du thiab txhim khu kev qha rau kev tsim kho, scaffolding thiab cov ntawv thov kev lag luam.
