    我先觀察彩鋼板外(wai)露鋼(gang)(gang)材如斷面等(deng)是否結晶細密(mi)，是否發(fa)灰、發(fa)暗(an)和(he)雜質(zhi)。若(ruo)切面是結晶細密(mi)型的(de)(de)(de)則(ze)是質(zhi)量比較(jiao)優越(yue)的(de)(de)(de)。我們(men)首(shou)先得考慮基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)和(he)腹(fu)膜(mo)鍍(du)層的(de)(de)(de)厚(hou)(hou)度(du)，比較(jiao)好(hao)的(de)(de)(de)彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)是0.02~0.05mm，覆(fu)膜(mo)或者涂層厚(hou)(hou)度(du)往(wang)(wang)往(wang)(wang)只有(you)(you)0.15mm以(yi)下(xia)。 觀(guan)察基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)厚(hou)(hou)度(du)和(he)覆(fu)膜(mo)的(de)(de)(de)厚(hou)(hou)度(du)，彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)是有(you)(you)基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)和(he)彩(cai)色的(de)(de)(de)腹(fu)膜(mo)或者鍍(du)層構成的(de)(de)(de)。聽聲(sheng)音(yin)用(yong)手指或用(yong)硬(ying)物(wu)敲(qiao)擊彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)材質(zhi)如果較(jiao)差，則(ze)發(fa)出來的(de)(de)(de)聲(sheng)音(yin)是悶的(de)(de)(de)，金屬聲(sheng)音(yin)不明顯(xian)，材質(zhi)較(jiao)好(hao)的(de)(de)(de)彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)金屬聲(sheng)音(yin)是比較(jiao)響亮、清脆的(de)(de)(de)。觀(guan)察彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)外(wai)漏邊緣，拿到(dao)一塊彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，因為(wei)從影響彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使(shi)(shi)用(yong)時(shi)間來看，基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚(hou)(hou)度(du)是很重要(yao)的(de)(de)(de)。而有(you)(you)些(xie)生產彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)廠家往(wang)(wang)往(wang)(wang)在基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)及彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)涂層或覆(fu)膜(mo)上(shang)做(zuo)手腳，他們(men)降(jiang)低(di)(di)基(ji)(ji)(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚(hou)(hou)度(du)，但是增(zeng)加腹(fu)膜(mo)的(de)(de)(de)厚(hou)(hou)度(du)來降(jiang)低(di)(di)彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)生產成本，這就大大降(jiang)低(di)(di)了彩(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使(shi)(shi)用(yong)壽命了。
