When selecting a Heavy Duty Vacuum Suction Cup, always factor in a safety margin. If you're lifting a 100 kg object, consider choosing a model rated for at least 150 kg. For larger panels or heavier materials, dual or multi-cup configurations may be required to distribute the load more evenly.

Contact Surface: Smooth, Rough, or Porous?

Not all surfaces are created equal, and the Heavy Duty Vacuum Suction Cup must match the surface texture and material. These tools perform best on smooth, flat surfaces such as glass, polished stone, or finished metal. For slightly rough or curved surfaces, specialized Heavy Duty Vacuum Suction Cup designs with flexible edges or deeper cup profiles can offer improved sealing.

Avoid using standard Heavy Duty Vacuum Suction Cups on porous surfaces like untreated wood or textured tile, as maintaining suction will be difficult or impossible. In these cases, alternative lifting methods or surface treatments may be necessary before using suction equipment.
