These magnets have a pull strength of over 100 kilograms (100,000 grams).
All pull strengths are measured against 3mm mild steel. This is the amount of effort required to remove the magnet from a piece of un-coated 3mm mild steel. Thicker metals will increase the pull strength, whereas thinner metals will decrease the pull strength of the magnet. You should consider the material you will be attaching your magnet to when evaluating the required pull strength. Allowances should be made for any coatings (such as powder coating, paint, vinyl, plastic, etc.) which may affect the pull strength of the magnet.
