STC Doors are a great way to fight back against noise pollution!
No matter where your office building is located, controlling outside noise pollution is always a challenge! You have a certain amount of control over what happens within the walls of your buildings, but your authority officially ends at the street. Traffic noise frequently exceeds 70 adjusted decibels (dBA), which can cause permanent hearing loss, and if you’re located near train tracks or an airport, you can count on frequent interruptions at the worst possible time! The good news is that our team at National Custom Hollow Metal is here to help, and we can give you a no-obligation quote for Safe Sound Transmission Control (STC) doors and frames in two hours or less!
Safe Shot Ballistic doors offer superior defense against armed attackers!
Gun violence is a reality throughout the world, and no community is ever truly safe. Countless violent incidents have occurred at American churches, schools, government offices, and even military bases, and many of the attacks are already over before the first police officer arrives on the scene. The only thing the attackers have in common is the desire to inflict as much harm as possible in the shortest amount of time, and the only thing the victims have in common is that they never imagined it could happen to them! But criminals are no match for vigilant citizens who take the proper precautions, and our team at National Custom Hollow Metal is proud to offer custom-built Safe Shot Level 3 Ballistic Doors and Frames that are strong enough to stop a .44 magnum round!
