We can help you find a reliable Chinese manufacturer specializing in commercial-grade steel door knobs. You can have the door knobs manufactured according to your specifications. We can help you purchase components that are functional and durable at prices that are much lower than you would get domestically. We work with the Chinese manufacturer to ensure that the products are of the highest quality.  

Typical materials: Various grades of steel

Steel is an alloy made of iron and some parts of carbon. There are nearly 3,500 different grades of steel. SS316, SS316L, SS304, and A216 are some commonly used steel grades in manufacturing.

Many people prefer to use SS304 for door knobs.

  • Door knobs are touched by many people every day, making them a common mode of bacteria transfer. With SS304, the chances of bacteria remaining on door knobs are lowered, which in turn lowers the rate of bacteria transfer.
  • SS304 is highly resistant to corrosion. You can use stronger chemicals to clean your door knobs, which makes them even more hygienic.
  • Steel door knobs brighten the aesthetics of your home or office as they provide a clean, minimalist finish.

Material composition

  • 18% Chromium
  • 8% Nickel
  • 0.08% Carbon

Common MOQ: 100 to 10,000 pcs
