而當冷鍍鋅作為重防腐涂料的底層，總配套涂層厚度大于180微米時，為保證整個涂層的附著力，鋼材表面粗糙度Rz應(yīng)大于60微米。鍍鋅角鋼優(yōu)點編輯1、處理費用低：熱浸鍍鋅防銹的費用要比其他漆料涂層的費用低；2、持久耐用：熱鍍鋅角鋼具有表面光澤，鋅層均勻，無漏鍍，無滴溜，附著力強，抗腐蝕能力強的特性，在郊區(qū)環(huán)境下，標準的熱鍍鋅防銹厚度可保持50年以上而不必修補；在市區(qū)或近海區(qū)域，標準的熱鍍鋅防銹層則可保持20年而不必修補；3、可靠性好：鍍鋅層與鋼材間是冶金結(jié)合，成為鋼表面的一部份，因此鍍層的持久性較為可靠；4、鍍層的韌性強：鍍鋅層形成一種特別的冶金結(jié)構(gòu)，這種結(jié)構(gòu)能承受在運送及使用時受到機械損傷；5、保護：鍍件的每一部分都能鍍上鋅，即使在凹陷處、尖角及隱藏處都能受到保護；6、省時省力：鍍鋅過程要比其他的涂層施工法更快捷，并且可避免安裝后在工地上涂刷所需的時間。鍍鋅角鋼外觀質(zhì)量編輯角鋼的表面質(zhì)量在標準中有規(guī)定，一般要求不得存在使用上有害的，如分層、結(jié)疤、裂縫等。角鋼幾何形狀偏差的允許范圍在標準中也有規(guī)定，一般包括彎曲度、邊寬、邊厚、頂角、理論重量等項，并規(guī)定角鋼不得有的扭轉(zhuǎn)。</p></p><br
