Infomesen blong Testing
Roofing sheet testing i wan kaen blong test we laboratori blong ZHONGXI Testing i providem long ol difren kaen sip blong rua, we ol man i yusum long haos, warohaos, faktori, kol hum, mo ol bigfala bilding long haos blong wool, sip blong metal, sip blong plastik, sip blong ASPHALT, mo sip blong faybroglas. Test blong roofing sheet testing i kovaem ol samting olsem thickness blong sip, strength blong matiriel, resistens blong korosion, resistens blong win mo ren, mo ol karakteristik we i mekem se sip i save stap gud long klima we i hot o i ren tumas.
Purpos blong roofing sheet testing i blong save se sip blong rua i save holem weta mo san long taem we i long, i no korode kwik, i no brek daon we win i strong, mo i save protektem man mo propati anda long rua. Ol teknik we laboratori i yusum inkludum tensile testing blong save strength blong matiriel, bend testing blong save se sip i save bend i no kreke, impact testing blong save se sip i holem hit we i kam, salt spray testing blong save se koating mo metal i no rast, mo hardness testing blong save se sip i had bitim ol narafala sip we i luk olsem.
Proses blong testing i stat we kliet i sendem sampl blong sip, laboratori i checkem sampl, i lukluk gud se sip i wanem kaen matiriel, i tekem ol item we kliet i wantem, i mekem test anda ol standad we iapply, mo afta we test i finis, laboratori i givim testing report long kliet. Ol koa parameter we laboratori i checkem inkludum tensile strength, yield strength, elongation, coating thickness, coating adhesion, bend performance, impact resistance, hardness, chemical composition, mo dimensional deviation blong sip.
Roofing sheet testing i impotan tumas long indastri blong konstarksen, from se sip blong rua i wan pat we i protektem hol bilding. Sip we i no pas test i save bringem problem olsem liklik hol we weta i save kam intru, korosion we i stat kwik, mo sip we i fold o i flai we win i strong. Olse, man we i bildim haos mo man we i mekem sip oli nidim test blong save se prodak oli stap anda ol spesifikasi we oli bin planem.
ZHONGXI Testing i acceptem ol sampl blong roofing sheet testing mo ol narafala test blong matiriel blong konstarksen, mo i givim ansa long 7-15 woking de, depend long ol item we kliet i chosem mo long kaen blong sampl we i sendem.

Sampl i mas markem blong kliet blong mekem se laboratori i save identifaem prodakt batc.
Wanem kaen testing item oli inkluudem long roofing sheet testing?
Ol item we oli inkluud i depend long kaen blong sip mo ol standad we i apply. Long metal sip, ol common item inkludum tensile strength, yield strength, elongation, bend testing, coating thickness, coating adhesion, salt spray resistance, mo kimikal komposisiS. Long plastic mo FRC sip, item inkludum weta sojksn, impact resistance, UV ageing, mo light transmisiS. Long sandwich sip, item inkludum foam densiti, adhesiv strength bitwin skin mo koa, mo fire behavior. Kliet mo injinia oli save diskusem blong chosem item we i fit long yus blong sip mo standad blong maket we prodak i save go.
Summary
Roofing sheet testing i kovaem ol mekanikal, koating, weathering, dimensiol, mo fire test blong difren kaen sip blong rua, inkludum galvanized steel sip, aluminum sip, FRC sip, plastik sip, sandwich panel, mo waterproofing membrane. ZHONGXI Testing i acceptem ol sampl blong roofing sheet testing mo blong ol testing item we i relatem, mo turnaran blong servisi i normally 7-15 woking de depend long ol item mo kaen blong sampl we kliet i sendem.
