Ultimate Guide to Buying the Best Padlock For Storage Unit

When aiming to buy a padlock or a set of padlocks, you want one that will provide optimum safety and will be your money's worth. Knowing which factors are important to look out for can save you time and money, not to mention give you a high-security product.

This section will give you pointers regarding the most important aspects you keep in mind when buying a padlock.

Body Material

The best disc padlock will be made of stainless steel, a material that is well known for being durable and highly resistant to fracture. Always go for stainless steel made padlocks.

Steel can different grades; however, the best grades are ASTM certified. If possible, and within your budget, spend a few bucks more and go for ASTM certified padlocks.

With or Without Lock Combinations

New padlocks have a code combination for added security. These combinations can number in the thousands, so it is impossible to guess the code even after multiple attempts.

If you want to set your own combination code for added security, go for these. However, never write your code down and make sure it's a combination you can easily recall (but not something too obvious).

Indoor or Outdoor Use

Outdoor use includes container storage units, storage sheds, garage doors, and much more. If you want security for outdoor uses, the padlock must be corrosion-resistant. While most padlocks are rust-resistant, some have added layers of protective coating for outdoor use.

Indoor use includes gym lockers and toolboxes. While high corrosion resistance may not be a key factor here, you would still want one that lasts long. You may need to lubricate padlocks periodically, regardless of where you use them, but outdoor locks should be maintained more meticulously.

High Cutting Resistance

A must-have feature for outdoor use. Cutter-resistant locks cannot be cut with wire or barb cutters, and are ideal for garage locks or storage units in construction sites.

Keyed Alike or Differently

Keyed alike means the same key can be used to unlock other locks of the same pack. Keyed differently means the keys are specific to one lock only. Both have advantages, but for high safety, keyed differently is a better choice.
