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. For medium-sized shelves, trapezoidal holes and butterfly holes are used in the market. The trapezoidal hole is easy to punch and easy for customers to carry out secondary expansion; the butterfly hole is beautiful and elegant, and it is easy to install. There are also manufacturers in the South that use their own unique hole type, so customers must rely on their manufacturers for shelf modifications.
