1. 不(bu)銹鋼瓦楞形板外形尺寸(cun)

 從圖5-37和(he)圖5-39可以看(kan)出不銹鋼瓦楞形(xing)(xing)板的(de)外表(biao)形(xing)(xing)狀是有(you)規律(lv)、周期性(xing)變化的(de)，而且彎曲深度(du)較小、形(xing)(xing)狀單(dan)一，不僅有(you)橫向波(bo)(bo)(bo)紋，而且還有(you)縱向波(bo)(bo)(bo)紋。所以說，其形(xing)(xing)狀既簡(jian)單(dan)又復(fu)雜(za)，簡(jian)單(dan)是指形(xing)(xing)狀單(dan)一，有(you)規律(lv)；復(fu)雜(za)是指不僅有(you)橫向波(bo)(bo)(bo)紋，而且還有(you)縱向波(bo)(bo)(bo)紋。這就(jiu)給(gei)不銹鋼瓦楞形(xing)(xing)板的(de)成型(xing)帶來不小的(de)難度(du)，在成型(xing)工藝(yi)上必須(xu)采取相應(ying)的(de)工藝(yi)措(cuo)施和(he)手段，方能(neng)保證獲(huo)得(de)要求的(de)外形(xing)(xing)尺(chi)寸和(he)成型(xing)質(zhi)量(liang)。

 圖(tu)5-39是不(bu)銹鋼(gang)瓦(wa)楞(leng)形(xing)板的實物照片(pian)，從圖(tu)片(pian)可以(yi)看出，不(bu)銹鋼(gang)瓦(wa)楞(leng)形(xing)板的外表和(he)形(xing)狀是非常(chang)美觀(guan)、漂亮的，具有較高的觀(guan)賞性(xing)，如同工藝品、裝(zhuang)飾品。
