STC Doors are your best defense against a noisy world!
Whether you spend your days in a large office in a major city center or someplace more suburban, you’re subjected to a cacophony of loud sounds everywhere you go. Most of us are accustomed to routine noises and learn to tune them out, and we wear hearing protection while using power tools or operating heavy equipment. But we don’t always realize just how much of an auditory onslaught we face each day, and it’s time to level the playing field! National Custom Hollow Metal is proud to offer custom-built Sound Transmission Control (STC) doors, and we can ship them on your schedule!
It’s a dangerous world, and Safe Shot Ballistic doors offer superior protection!
It’s a little terrifying to turn on the news today when the headlines are filled with stories of violence throughout the world. Violence is no longer limited to war-torn countries or run-down neighborhoods, and there’s no such thing as a truly “safe” community. But violent criminals are no match for vigilant citizens, and our team at National Custom Hollow Metal is ready to help you keep schools, workplaces, and government offices protected from the threat of gun violence. We proudly offer custom-built Safe Shot UL 752 Level 3 Ballistic Doors and Frames to order, and they’re capable of stopping a .44 magnum round!
