樓承板，也叫壓(ya)(ya)型(xing)(xing)(xing)鋼板(ban)、鋼承板(ban)、鋼樓(lou)(lou)承板(ban)。最早(zao)的(de)(de)(de)叫法(fa)叫壓(ya)(ya)型(xing)(xing)(xing)鋼板(ban)，所有(you)經(jing)壓(ya)(ya)板(ban)機壓(ya)(ya)制成(cheng)型(xing)(xing)(xing)的(de)(de)(de)鋼板(ban)的(de)(de)(de)統稱。樓(lou)(lou)承板(ban)是(shi)采用(yong)鍍鋅鋼板(ban)經(jing)輥(gun)壓(ya)(ya)冷彎成(cheng)型(xing)(xing)(xing)，其(qi)截面(mian)(mian)成(cheng)V型(xing)(xing)(xing)、U型(xing)(xing)(xing)、梯(ti)形或類似這(zhe)幾種形狀(zhuang)的(de)(de)(de)波形，主要用(yong)作永(yong)久性模(mo)板(ban)，也可被選(xuan)為其(qi)他用(yong)途。最早(zao)的(de)(de)(de)壓(ya)(ya)型(xing)(xing)(xing)鋼板(ban)主要是(shi)用(yong)于(yu)廠房(fang)屋面(mian)(mian)的(de)(de)(de)屋面(mian)(mian)板(ban)，后面(mian)(mian)有(you)用(yong)于(yu)樓(lou)(lou)層(ceng)的(de)(de)(de)壓(ya)(ya)型(xing)(xing)(xing)鋼板(ban)后逐(zhu)漸分類稱為樓(lou)(lou)承板(ban)。
