When your distributors insist on quality, you should insist on DefendDoor!
National Custom Hollow Metal currently manufactures several premium products, including stainless steel, galvanneal, and lead-lined doors and frames. We also now offer Sound Transmission Control (STC doors) that can reduce noise pollution, and Ballistic doors that are capable of stopping a .44 magnum round. But every year DefendDoor custom hollow metal doors and frames continue to be our most popular product line, for many great reasons.
For the ultimate peace of mind, NCHM offers custom ballistic doors!
If you regularly follow the news, you’ve become accustomed to regular stories about heavily armed gunmen going on surprise shooting sprees. In many cases, the shooters are disgruntled employees seeking revenge, but just as often, their targets are selected completely at random. The only thing that the shooters seem to have in common is that they’re highly motivated, they depend on the element of surprise, and can inflict a lot of casualties before the police arrive. The only thing that their victims have in common is that they never thought that it could possibly happen to them.
NCHM can build 4 sided box doors to your exact specifications!
Many distributors are experiencing an increasing demand for box doors, and for very good reasons. They’re durable, look great, are practically maintenance free, and offer the fire door labeling that their clients require. They’re also surprisingly affordable, and our team at National Custom Hollow Metal offers industry leading turnaround times on all orders (and expedited shipping options for distributors that are facing tight deadlines).
Need to create a quiet environment? NCHM can manufacture STC doors to your exact specifications!
Most city dwellers are used to the constant sound of traffic noise, and most office dwellers are used to the “dull roar” created by their co-workers as they type and talk on the phone. Some people cope with the noise better than others, but most prefer a quiet work environment. And for businesses such as recording studios and music performance halls, controlling noise is crucial.
