There are actually quite a lot of hole patterns for the columns of warehouse shelves, and the hole patterns determine the use of different hanging pieces, so it is still very critical.
The most common and simplest is the butterfly hole. Currently, left and right light-duty and most medium-sized laminate shelves use this hole type. It is characterized by simple processing, low cost, and of course stability and firmness. It's worse.
The old hole types include inverted figure-shaped holes, water drop holes/gourd holes, inverted triangular holes, and diamond holes.
Butterfly hole: Because the hole in the column is shaped like a butterfly, it is named butterfly hole. Butterfly holes are generally used on light shelves and medium-sized shelves.
Gourd hole: Because the shape of the hole is like a gourd, it is called a gourd hole. This hole type is a new hole type that has been developed in recent years. The shelves using this hole type are relatively delicate, so they are commonly used. Shelves designed for home use also have a lighter load capacity.
Inverted figure-eight hole: The hole shape is like the figure eight written upside down, so it is called inverted figure-eight hole. It is mostly used for heavy-duty shelves, with a large load capacity and a little troublesome to install.
Rhombus hole: Also named because of its shape, it is mostly used on heavy-duty shelves with larger loads.
Inverted triangular hole: The hole is shaped like an inverted triangle, so it is called inverted triangular hole. It is mostly used for heavy-duty shelves.
Although there are many types of shelf holes, the most commonly used ones are diamond holes, followed by butterfly holes.
The shelves we use, including supermarket shelves, civilian shelves and industrial shelves, etc., have regular holes punched in the columns and other places of the shelves. The shapes of the holes are the same, some are butterfly holes, some are drop holes, and some are diamond-shaped holes. Taking industrial storage shelves as an example, diamond-shaped holes are generally used.
