Storage shelves, cantilever shelves of the column, beam mostly have a variety of perforations, most are butterfly holes. The purpose of the openings is originally to replace the traditional processes such as the Welded type. The welded types have been found to bring a lot of benefits in later use.
The Frame strip is arranged on a lathe and pressed to create butterfly holes. Take a 2m high column as an example, there will be no less than 18 butterfly holes on the designed column. Since the Henglian frames are all perforated, the BEAM height can be adjusted arbitrarily, making the BEAM gradually increase or decrease from 2 to 5. Such free adjustment can be adjusted according to the actual size of the goods when storing, which can achieve the effect of storing multiple goods on a set of shelves, replacing the Welded type process. Shelves have also become more aesthetically pleasing in appearance.
Butterfly hole is popular for two reasons: first, the shelf can be disassembled, so that handling and installation are more convenient. Second, according to the size of the storage goods, the cantilever and beam can be adjusted to make the shelves more practical.
