    觀察基板厚度和覆膜的厚度，彩鋼板是(shi)有基板(ban)(ban)(ban)(ban)和彩(cai)色的(de)(de)腹(fu)膜(mo)(mo)或(huo)者(zhe)鍍層(ceng)(ceng)構(gou)成的(de)(de)。我們首(shou)先得考慮基板(ban)(ban)(ban)(ban)和腹(fu)膜(mo)(mo)鍍層(ceng)(ceng)的(de)(de)厚(hou)度(du)(du)(du)，比(bi)較好的(de)(de)彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)基板(ban)(ban)(ban)(ban)是(shi)0.02~0.05mm，覆膜(mo)(mo)或(huo)者(zhe)涂層(ceng)(ceng)厚(hou)度(du)(du)(du)往往只有0.15mm以(yi)下。因為(wei)從影響彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)使用(yong)時(shi)間來看，基板(ban)(ban)(ban)(ban)的(de)(de)厚(hou)度(du)(du)(du)是(shi)很重(zhong)要的(de)(de)。而(er)有些生產彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)廠家往往在基板(ban)(ban)(ban)(ban)及彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)涂層(ceng)(ceng)或(huo)覆膜(mo)(mo)上做手腳，他們降(jiang)低(di)基板(ban)(ban)(ban)(ban)的(de)(de)厚(hou)度(du)(du)(du)，但(dan)是(shi)增加腹(fu)膜(mo)(mo)的(de)(de)厚(hou)度(du)(du)(du)來降(jiang)低(di)彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)生產成本，這就(jiu)大(da)(da)大(da)(da)降(jiang)低(di)了彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)使用(yong)壽命了。

    聽聲(sheng)音用(yong)手指(zhi)或用(yong)硬物敲(qiao)擊(ji)彩(cai)鋼板，彩(cai)鋼板的(de)材質(zhi)如果較差，則發出來的(de)聲(sheng)音是(shi)悶的(de)，金屬聲(sheng)音不明顯，材質(zhi)較好的(de)彩(cai)鋼板金屬聲(sheng)音是(shi)比(bi)較響亮(liang)、清脆(cui)的(de)。觀察彩(cai)鋼板的(de)外(wai)漏邊緣(yuan)，拿(na)到(dao)一塊彩(cai)鋼板，我先(xian)觀察彩(cai)鋼板外(wai)露鋼材如斷面等是(shi)否結晶(jing)細(xi)密，是(shi)否發灰、發暗和(he)雜質(zhi)。若切面是(shi)結晶(jing)細(xi)密型(xing)的(de)則是(shi)質(zhi)量比(bi)較優越的(de)。
