Daim tawv nqaij ntawm ib lub trailer txiav txim siab ntev npaum li cas chav tsev nyob, nws hnyav npaum li cas thiab nws zoo li cas tom qab xyoo ntawm txoj kev. Cov ntawv txhuas yog qhov kev xaiv vim tias nws ua ke nrog qhov hnyav nrog corrosion tsis kam thiab yooj yim fabrication, tab sis qhov tshwj xeeb yuav tsum tau ua los ntawm plaub qhov kev txiav txim siab tsis yog ib qho: alloy, thickness, tiav thiab profile. Lub tsheb thauj khoom thauj khoom, lub tsheb thauj khoom noj, RV thiab cov khoom siv hauv lub txaj tag nrho xav tau cov lus teb sib txawv.
Vim li cas Trailer Skin Selection Matters
Trailer lub cev nyob nrog tas li flexing, txoj kev tshuaj tsuag, ntsev, hnub thiab cuam tshuam los ntawm cov khoom thauj. Ib daim tawv nqaij uas nyias dhau dents thiab qaug zog ntawm cov fasteners; ib qho uas hnyav dhau tus nqi payload thiab roj; thiab ib qho tiav xaiv rau qhov tsos ib leeg tuaj yeem pleev xim los yog tev hauv ob lub caij. Ua haujlwm los ntawm plaub qhov kev txiav txim siab kom tsis txhob muaj feem ntau ntawm kev ua tsis tiav.
Alloyteeb lub zog, formability thiab corrosion cwj pwm.

Alloy xaiv: 3003, 5052 thiab 6061 Muab piv
Aluminium alloys ntxiv magnesium, manganese lossis silicon rau lub hauv paus hlau los hloov nws tus cwj pwm. Rau kev ua haujlwm trailer peb qib hauv qab no npog yuav luag txhua qhov yuav tsum tau ua, los ntawm cov vaj huam sib luag sab hauv kom zoo nkauj rau cov tswv cuab ntawm cov txheej txheem welded.
| Alloy thiab tempered | Hom tensile zog | Lub zog | Zoo tshaj plaws rau |
|---|---|---|---|
| 3003-H14 | kwv yees li . 130 - 180 MPa | Formability zoo heev, zoo corrosion kuj, tus nqi qis tshaj ntawm peb | Cov vaj huam sib luag sab hauv, cov tawv nqaij kom zoo nkauj, sib sib zog nqus- kos los yog khoov kom zoo nkauj |
| 5052-H32 | kwv yees li . 215 - 275 MPa | Qhov zoo tshaj plaws corrosion kuj, tshwj xeeb tshaj yog tiv thaiv dej ntsev, zoo formability thiab weldability | Cov tawv nqaij sab nrauv, cov nkoj hauv hiav txwv thiab cov ntug hiav txwv, cov chaw raug huab cua hnyav |
| 6061-T6 | kwv yees li . 290 - 310 MPa | Lub zog siab tshaj plaws, zoo heev weldability, zoo dav corrosion kuj | Cov txheej txheem thav duab, tus ntoo khaub lig cov tswv cuab, kev txhawb nqa, flooring ntawm hnyav-cov dej num |
Rau qhov zoo tib yam trailer siding, 3003 thiab 5052 yog cov tswv yim xaiv, nrog 5052 nyiam nyob qhov twg ntsev los yog tsis tu ncua noo noo xav tau. Qhov twg daim ntawv nws tus kheej nqa load, xws li nyob rau hauv ib lub lawj los yog ib tug reinforced sidewall, 6061-T6 nyob rau hauv ib tug hnyav gauge hloov steel cov tswv cuab thiab tshem tawm qhov hnyav tib lub sijhawm.
Sheet Thickness ranges thiab Load Capacity
| Ntsuas band | Yam ntxwv | Hom kev siv | Load cwj pwm |
|---|---|---|---|
| 0.025 - 0.040 hauv (0.64 - 1.02 mm) | Lub teeb, tus nqi qis, yooj yim txiav thiab khoov | Sab hauv ob sab phlu, qab nthab panels, lub teeb lub luag hauj lwm cosmetic tawv | Tsawg; dents los yog puncture nyob rau hauv kev cuam tshuam, xav tau kev pab cuam nyob ze |
| 0.050 - 0.080 hauv (1.27 - 2.03 mm) | Sib npaug lub zog thiab qhov hnyav, kev puas tsuaj zoo | Sidewalls thiab ru tsev ntawm cov khoom thauj thiab cov khoom siv hluav taws xob | Nruab nrab; feem ntau xaiv rau cov hom phiaj dav dav trailer |
| 0.090 hauv thiab siab dua (2.29 hli thiab siab dua) | Lub zog siab tshaj plaws thiab cuam tshuam tsis kam, hnyav dua | Hnyav-lub luag haujlwm thiab tawm- txoj kev tsheb ciav hlau, hauv pem teb rau cov khoom siv trailer | Siab; resists taw tes loads los ntawm cov cav tov thiab pallets |
Xaiv qhov ntsuas qhov nyias tshaj plaws uas ua tau raws li qhov yuav tsum tau muaj es tsis yog qhov ntsuas qhov thinnest uas tuaj yeem ntsia tau, tom qab ntawd txheeb xyuas qhov sib nrug ntawm kev txhawb nqa. Fastener spacing, rivet los yog ntsia hlau pitch, thiab muaj cov nplaum nplaum tag nrho hloov qhov zoo nruj ntawm ib daim ntawv thickness.
Nto tiav: Xim, Anodizing, Mill tiav thiab pob zeb diamond phaj
| Ua kom tiav | Qhov zoo | Kev txwv | Hom kev siv |
|---|---|---|---|
| Painted los yog hmoov coated ntawv | Cov xim dav dav, ruaj khov ntawm cov khoom ua ntej- kho cov hlau, yooj yim kom phim lub fleet livery | Yuav nti los yog khawb; xim yuav ploj mus ntev nrog lub hnub raug | Sab nrauv panels, muaj npe thiab kev cai trailer |
| Anodized ntawv | Txhim kho corrosion kuj, xim hlau zoo li, tsis muaj xim rau tev | Kev xaiv xim tsawg dua li cov xim pleev xim thiab cov nqi tsev siab dua | Sab nrauv trim, zoo nkauj panels, premium finishes |
| Mill tiav daim ntawv | Tus nqi khoom qis tshaj plaws, npaj rau kev pleev xim tom qab | Oxides thiab stains yog sab laug, xav tau kev tiv thaiv ntxiv | Cov vaj huam sib luag sab hauv thiab tus nqi - tsav tsheb |
| Pob zeb diamond phaj | Slip resistant, hides khawb thiab dents zoo | Hnyav dua li daim ntawv du thiab nyuaj dua los ntxuav | Trailer pem teb, ramps, fenders, cov kauj ruam, cov khoom siv sab nrauv |
Qhov twg yog xaiv tiav, daim ntawv npoo thiab tag nrho cov txiav qhib yuav tsum tau muab kaw los yog coated. Cov npoo uas tsis muaj kev tiv thaiv yog qhov uas filiform corrosion thiab xim blistering pib ntawm pleev xim rau trailer.
Daim ntawv profile: du, pob zeb diamond, embossed thiab corrugated
| Profile | Nta | Hom kev siv |
|---|---|---|
| Daim ntawv du | Flat uniform nto, yooj yim los ntxuav thiab yooj yim rau decal | Sab nrauv sab nrauv, sab hauv phab ntsa, huv si aesthetic panels |
| Pob zeb diamond phaj | Raised tread qauv, plam resistant, hides kev puas tsuaj | Pem teb, ramps, toolbox tops, siab - chaw tsheb |
| Embossed ntawv | Raised qauv ntxiv kev ntxhib los mos thiab lub zos rigidity | Sab hauv ob sab phlu, zoo nkauj trim, linings pom lub teeb puas |
| Corrugated ntawv | Ribbed qauv tsa qhov nruj ntawm qhov kev taw qhia | ru tsev, sab nrauv phab ntsa, panels qhov twg rigidity yuav tsum los ntawm qhov profile |
Daim ntawv profiled tuaj yeem hloov qhov hnyav dua qhov ntsuas qhov chaw nruj, tsis yog lub zog, tswj hwm lub vaj huam sib luag. Corrugated ru tsev, piv txwv li, ncua ntxiv ntawm cov hneev dua ib daim ntawv du ntawm tib tuab, txawm hais tias lawv khaws cov av hauv cov tav thiab xav tau kev saib xyuas ntau dua ntawm cov seams.
Cov lus nug nquag
Q: Qhov twg aluminium alloy yog qhov zoo tshaj plaws rau trailer siding?
5052-H32 yog cov lus teb dav dav zoo tshaj plaws vim tias nws sib xyaw ua ke muaj zog corrosion kuj nrog zoo formability. 3003-H14 yog ib tug nqi-zoo lwm txoj rau sab hauv, sheltered trailers, thaum 6061-T6 yog tshwj tseg rau structural panels thiab thav ntawv.
Q: Ntev npaum li cas yuav tsum trailer daim tawv nqaij?
Feem ntau cov khoom thauj thiab cov khoom siv hluav taws xob siv 0.050 txog 0.080 nti daim ntawv rau cov phab ntsa thiab lub ru tsev. Sab hauv hauv ob sab phlu tuaj yeem yog 0.025 txog 0.040 nti, thiab hnyav-lub luag haujlwm lossis tawm- txoj kev hauv pem teb pib ntawm 0.090 nti thiab siab dua.
Q: Cov ntawv txhuas puas tuaj yeem txuas ncaj qha mus rau steel trailer ncej?
Nws tuaj yeem, tab sis kev sib koom ua ke xav tau kev sib cais. Siv cov coated lossis stainless fasteners nrog nylon ntxhua khaub ncaws, siv lub sealant ntawm cov hlau tsis sib xws, thiab ua kom cov dej ntws tawm kom meej kom tsis txhob ya raws qhov chaw sib cuag thiab ua rau galvanic corrosion.
Q: Puas yog pob zeb diamond phaj tsim nyog rau qhov hnyav ntxiv?
Yog nyob qhov twg neeg taug kev los yog cargo slides. Nyob rau hauv pem teb, ramps thiab cov kauj ruam hauv qab qhov kev tiv thaiv plam thiab dent nkaum tshaj qhov hnyav hnyav. Rau sab nrauv sab nrauv, daim ntawv smoother yog sib dua thiab yooj yim dua los ntxuav.
Q: Puas yog anodising nres corrosion kiag li?
Tsis yog. Anodising ua tau zoo txhim kho qhov saum npoo ntawm qhov tsis kam mus rau staining thiab abrasion, tab sis txiav npoo, drilled qhov thiab khawb tawm cov hlau liab qab uas tseem xav tau kev saib xyuas. Sealing cov npoo txuas ntxiv lub neej kev pabcuam ntawm txhua daim tawv nqaij anodised.
Q: Dab tsi nto tiav yog qhov zoo tshaj plaws rau lub tsheb thauj khoom?
Daim ntawv du nrog kev huv, yooj yim - huv huv yog nyiam rau cov khoom noj khoom haus sib cuag thiab sab hauv, nrog pob zeb diamond phaj txwv rau cov kauj ruam thiab hauv pem teb. Painted los yog hmoov coated sab nrauv panels muab qhov widest branding xaiv.
