304 stainless steel metal king isolator is made of food grade 304 stainless steel, formed by CNC stamping, and polished on the surface, which is both beautiful and easy to clean. The thickness of the plate is generally about 3mm, and the size and pores can be customized (the default pore size is 4.1-4.2mm), ensuring that the queen bee is effectively blocked while allowing worker bees to pass through, suitable for area separation and bee colony management in the beehive. The product has extremely high corrosion resistance, strength and hygienic safety, and provides professional customization and perfect after-sales service.
