|
Feature |
Kub-Dip Galvanized (HDG) Square Tube |
Ua ntej- Galvanized Square Tube |
|
Txheej txheem |
Tube yog tag nrho tsim, ces immersed nyob rau hauv molten zinc da dej |
Hlau sawb yog galvanized ua ntej lub raj tsim |
|
Zinc Txheej Thickness |
45-100 microns (nruab nrab 65-85μm), ntsib ISO 1461 & ASTM A123 tus qauv |
10-25 microns, muab kev tiv thaiv corrosion |
|
Txheej Bond |
Metallurgical bond ntawm zinc thiab hlau, tsis tshua muaj zog |
Zinc txheej siv rau lub tiaj tiaj tiaj, weld seam yuav tsum tau kov-nce |
|
Corrosion Resistance |
Superior, haum rau qhov hnyav sab nraum zoov ib puag ncig (25-75+ xyoo kev pab cuam lub neej) |
Zoo, haum rau sab hauv tsev lossis ib puag ncig me me |
|
Nto Zoo |
Matte grey nrog spangle qauv, me ntsis ntxhib kev ntxhib los mos |
Bright, du, uniform tsos |
|
Nqi |
Tus nqi pib siab dua, qis dua - lub sijhawm tu |
Kev lag luam ntau dua ua ntej, zoo tagnrho rau kev siv nyiaj - cov haujlwm tseem ceeb |
|
Cov ntawv thov zoo tshaj plaws |
Cov qauv tsim, fencing sab nraum zoov, marine ib puag ncig, kev tsim kho vaj tse |
Rooj tog, sab hauv tsev racking, automotive Cheebtsam, dav fabrication |

Ntsiab nta & qhov zoo
Premium Base Khoom: Ua los ntawm qib siab - qib carbon steel strips (Q195, Q235, Q355, S235JR, S355J2H, ASTM A500 Gr B/C), kom ntseeg tau zoo heev weldability, formability, thiab cov qauv kev ntseeg.
Superior Corrosion tiv thaiv: Kub-dip galvanized tubes muaj qhov tuab, metallurgically bonded zinc txheej (45-100μm) uas muab kev tiv thaiv tshwj xeeb tiv thaiv xeb thiab oxidation, ua kom ntev kev pab cuam lub neej nyob rau sab nraum zoov thiab corrosive ib puag ncig.
Precision Dimensional Tolerances: Sab nraud qhov ntev kam rau ua ± 0.5%, phab ntsa thickness kam rau ua ± 10%, ua tau raws li cov kev cai thoob ntiaj teb nruj rau kev siv cov qauv.
Clean & Smooth Sab hauv / Sab nrauv: Uniform square profile nrog du weld hlaws thiab cov phab ntsa tuab zoo ib yam, ua kom yooj yim sib dhos thiab kev zoo nkauj hauv cov ntawv thov raug.
Muaj peev xwm ua tau dav: Muaj nyob rau hauv cov qauv zeb ntev lossis kev cai txiav - mus rau - qhov ntev. Peb kuj muab kev pabcuam drilling, xuas nrig ntaus, miter txiav, thiab vuam kev pabcuam kom tau raws li cov kev xav tau tshwj xeeb.
Daim ntawv pov thawj zoo: Tag nrho cov khoom yog tsim nyob rau hauv ISO 9001 certified zoo tswj systems thiab CE certified rau European ua lag luam ua raws.
Quality Assurance & Mill Certificate
Kev Ntsuas Kev Ntsuas: Txhua pawg ntau lawm tau soj ntsuam nruj nrog rau kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg, kev ntsuas cov cuab yeej cuab yeej (tensile, yield, elongation), qhov tseeb qhov tseeb, thiab ntsuas zinc txheej thickness ntsuas.
Zinc Coating Verification: Txheej thickness yog ntsuas siv magnetic induction gauges ua raws li ASTM E376 thiab ISO 2178 tus qauv, ua kom tag nrho ua raws li ISO 1461 thiab ASTM A123 cov kev cai.
Cov ntaub ntawv: Tag nrho cov khoom xa tuaj suav nrog Mill Test Certificate (MTC) ua raws li EN 10204 3.1 lossis 3.2. Peb kuj muab Daim Ntawv Pov Thawj Keeb Kwm (CO), cov npe ntim khoom, thiab cov ntawv xa nyiaj ua lag luam rau kev lis kev cai seamless.
Thib peb-Kev soj ntsuam tog: Peb koom tes nrog ua ntej - kev tshuaj xyuas cov khoom xa tuaj los ntawm cov chaw lees paub xws li SGS, Bureau Veritas (BV), thiab Intertek los txheeb xyuas cov khoom zoo thiab kom muaj nuj nqis ua ntej thauj khoom.
