Medium-duty type bracks

Different types of shelves use different hole types for the beam to be hooked. The hole types commonly used in the market today include trapezoidal holes, butterfly holes, rhombic holes, bean sprouts holes, and eight-hole holes. The specific hole type does not stipulate the implementation standard, and most of them are the corresponding hole types adopted by each manufacturer according to their own production process. 對于中型貨架，市面上較多采用的是梯形孔和蝴蝶孔。梯形孔沖壓方便，便于客戶進行二次擴充；蝴蝶孔美觀大方，牢固易安裝。南方也有廠家采用自己獨有的孔型，這樣客戶再進行貨架改造則必須依靠其廠家。
