Why we need a iron padlock with brass plug?

There are many different kinds of iron padlock in market. Consumer usually will buy a padlock with cheaper price. Because they do not know what's different between the padlocks.The Padlock performance, strength, security, durability, corrosion resistance is what you should consider.

First, Strength, if a padlock with thicker body, bigger shackle dimeter, it will be stronger. So check about the dimensions of the lock thickness, height ,width is necessary.

Second, security, if a padlock with more pins, double locking but not single locking, with hardened steel shackle, we will consider this padlock has higher security. For example ,our plastic powder coating iron padlock has 5 pins for small size ,6 pins for bigger size ,has double locking physical design.

Third, durability, You may ask the supplier about the life testing of a padlock. Machining precision, components material will affect the testing result.

Forth, Corrosion resistance is also important. The material selection and surface treatment is critical factors. For example ,our plastic powder coated iron padlock has brass plug, stainless steel springs and brass pins. The small components inside are antirust. The Spray testing result will be better than those padlocks with iron pins and iron springs .You may double check these small components material before you place purchase order.
