Not all doors are created equal. While you can certainly find high-quality residential doors, if you're operating a business or simply want the best doors possible, you need to select commercial doors. These doors are designed to cope with the high stress that business use often places on them.
A business will often see far more foot traffic than the average home, for example. Businesses may also be more enticing targets for criminals, but the right doors can help keep them out.
That said, installing exterior commercial-quality doors can be tricky. You might find that there are gaps in the door. Fortunately, you can fill in these gaps with a variety of materials. You'll want the door to be flush with the frame or as full as possible.
The right doors can accomplish a lot of different things. Not only can high-quality doors deter or thwart criminals, but they can also make heating and cooling more efficient. If a door allows a lot of heat or air-conditioned air to escape, you may have to spend more keeping the interior temperature right.
With commercial doors, you can expect the doors to put up with a lot of abuse. Your business might be struck by high winds and heavy snow, for example. A properly installed commercial-quality door will often be able to shrug off bad weather..
