PPGL Galvalume Steel Roofing Sheets ASTM A755 Txuj

Ntawm Shandong Pinjie New Material Co., Ltd., peb tau tsim cov khoom siab tshaj -cov ntaub ntawv vov tsev rau ntau tshaj kaum xyoo. Peb PPGL galvalume steel vov tsev ntawv ua raws li ASTM A755 tus qauv sawv cev rau qhov kawg ntawm peb 10 xyoo ntawm kev lag luam kev paub thiab kev txhim kho txuas ntxiv. Cov kev daws teeb meem vov tsev no yog tsim los ua kom tau raws li qhov xav tau ntawm kev tsim kho niaj hnub no thoob plaws thaj chaw, kev lag luam, thiab kev lag luam.

PPGL sawv cev rau Pre-painted Galvalume Steel. Nws siv kub-dip Al-Zn alloy coated steel (55% Al, 43.5% Zn, 1.5% Si) ua cov khoom siv hauv paus. Cov txheej txheem ntau lawm suav nrog kev kho qhov chaw ua ntej, daim ntawv thov txheej txheej organic, thiab siab -kub curing los ntawm kev siv tshuab tsis tu ncua txheej txheej.

Khoom Khoom

Cov khoom siv hauv paus ua tau raws li DX51D + AZ qib qis carbon steel. Lub 55% Al-Zn alloy txheej ua ke nrog txhuas lub sij hawm ntev - lub sij hawm durability nrog zinc galvanic tiv thaiv. Pem hauv ntej txheej thickness ranges 10-50μm, rov qab txheej 5-50μm. Cov txheej txheem muaj xws li Polyester (PE), High Durability Polyester (HDP), thiab Polyvinylidene Fluoride (PVDF).

Ntau lawm khiav ntawm tag nrho automated nruam txheej kab. Galvalume coils yog uncoiled thiab welded rau kev ua haujlwm tas mus li. Cov substrates raug degreasing thiab tshuaj hloov pauv tshuaj. Primer thiab cov tsho tiv no saum toj kawg nkaus yog siv ua ntu zus nrog nruab nrab ci. Kev tshuaj ntsuam xyuas zaum kawg xyuas cov txheej thickness, adhesion, thiab xim sib xws ua ntej coiling.

PPGL vov tsev ntawv pab ntau yam kev lag luam thiab kev tsim kho kev lag luam. Corrugated profiles haum rau cov tsev khaws khoom lag luam thiab chaw xa khoom kom ntev - ncua kev teeb tsa. Pobzeb profiles ua haujlwm rau cov tsev nyob thiab cov tsev cog khoom ua liaj ua teb ntsuas kev zoo nkauj thiab kev ua haujlwm. Cov phiaj xwm ntug dej hiav txwv qhia AZ150 hnyav txheej rau ntsev tsuag tsis kam. Cov cheeb tsam huab cua kub tau txais txiaj ntsig los ntawm lub teeb xim PVDF coatings txo lub ru tsev kub ntawm 3-5 degree.

Kev Ua Haujlwm Zoo

Corrosion kuj tshaj tus qauv PPGI los ntawm 2-3 zaug. 55% Al-Zn txheej muab kev tiv thaiv tus kheej ntawm kev txiav cov npoo ncua kev tsim cov xeb liab. Cov cua kub zoo heev txo qis kev siv hluav taws xob hauv tsev los ntawm 15-20% thaum lub caij ntuj sov. Kev tsim kho lub teeb (4-6kg / m²) minimizes structural load. Kev teeb tsa nrawm nrog cov ntawv txog li 12 meters txo cov ntsiab lus sib koom.

Q1: Dab tsi yog qhov txawv ntawm PPGL thiab PPGI?
A: PPGL siv 55% Al-Zn alloy txheej thaum PPGI siv cov zinc txheej ntshiab. PPGL muaj 2-3 zaug zoo dua corrosion kuj, ua rau nws nyiam rau cov ntug dej hiav txwv thiab cov av noo ib puag ncig.

Q2: Yuav ua li cas xaiv cov txheej txheem tsim nyog?
A: Txheem PE rau ib puag ncig ib puag ncig; HDP rau thaj chaw muaj kev lag luam; PVDF rau cov ntug dej hiav txwv los yog siab UV raug nrog 15-20 xyoo warranty.

Q3: Qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi?
A: MOQ yog 5 metric tons rau tus qauv specifications. Cov xim tshwj xeeb lossis cov ntsuas tshwj xeeb xav tau 20 MT MOQ raws li kev teem sijhawm ntau lawm.

Q4: Lub sijhawm ua khoom lag luam yog dab tsi?
A: 7-10 hnub rau cov khoom lag luam. Kev tsim khoom yuav tsum tau 15-25 hnub suav nrog kev tsim khoom thiab kev tshuaj xyuas zoo.

Q5: Cov txheej txheem pov thawj zoo dab tsi muaj?
A: Cov ntawv pov thawj zeb xeem suav nrog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab txheej tuab. Adhesion xeem ib ASTM D3359 thiab ntsev tsuag tshuaj ntsuam ib ASTM B117 muaj raws li thov.

Q6: Dab tsi yog qhov tseem ceeb ntawm kev teeb tsa?
A: Cov txheej txheem zais zais pom zoo kom tiv thaiv cov dej ntws tawm. Yam tsawg kawg nkaus 250mm sab ncej puab thiab ib qho tag nrho corrugation kawg ncej. Stainless hlau fasteners xav tau rau kev siv ntug hiav txwv.

Q7: Cov kev pab them nqi dab tsi yog muab?
A: 5- xyoo txheej warranty thiab 10- xyoo txheej warranty rau cov khoom txheem. PVDF txheej muaj xws li 15-xyoo tsis-chalking, tsis-fading warranty.
