彩鋼卷板現在已經逐步得到了廣泛的應用，今天為大家詳細分析下如何辨別彩鋼卷板質量好壞的方法(fa)：
1：觀(guan)察(cha)彩(cai)鋼(gang)卷板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)厚(hou)度(du)和(he)覆膜的(de)(de)(de)(de)厚(hou)度(du)，彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)是(shi)有(you)基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)和(he)彩(cai)色的(de)(de)(de)(de)腹膜或者鍍(du)層(ceng)構成的(de)(de)(de)(de)。我們首先得考慮基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)和(he)腹膜鍍(du)層(ceng)的(de)(de)(de)(de)厚(hou)度(du)， 比較好的(de)(de)(de)(de)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)是(shi)0.02~0.05mm，覆膜或者涂層(ceng)厚(hou)度(du)往往只(zhi)有(you)0.15mm以下。因為從影(ying)響彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)使用時間來(lai)看，基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)厚(hou)度(du)是(shi)很重要(yao)的(de)(de)(de)(de)，而有(you)些生(sheng)(sheng)產彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)廠家(jia)往往在(zai)基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)及(ji)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)涂層(ceng)或覆膜上做手腳，他們降(jiang)(jiang)低基(ji)(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)厚(hou)度(du)，但是(shi)增加(jia)腹膜的(de)(de)(de)(de)厚(hou)度(du)來(lai)降(jiang)(jiang)低彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)生(sheng)(sheng)產成本，這就(jiu)大(da)大(da)降(jiang)(jiang)低了彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)使用壽命了。
2：聽聲(sheng)音(yin)(yin)用(yong)手(shou)指或用(yong)硬物敲擊彩(cai)鋼板，彩(cai)鋼板的(de)(de)材質如果(guo)較(jiao)差(cha)，則發出來(lai)的(de)(de)聲(sheng)音(yin)(yin)是悶的(de)(de)，金(jin)屬(shu)聲(sheng)音(yin)(yin)不明顯，材質較(jiao)好的(de)(de)彩(cai)鋼板金(jin)屬(shu)聲(sheng)音(yin)(yin)是比較(jiao)響(xiang)亮、清脆的(de)(de)。
3：觀(guan)察彩鋼(gang)板的外漏邊緣，拿(na)到一塊彩鋼(gang)板，我們要先觀(guan)察彩鋼(gang)板外露鋼(gang)材如斷面(mian)等是(shi)(shi)否結晶(jing)細密，是(shi)(shi)否發灰、發暗(an)和(he)雜質(zhi)。若(ruo)切面(mian)是(shi)(shi)結晶(jing)細密型(xing)的則是(shi)(shi)質(zhi)量比較優(you)越的。
