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!

Kerf frames are an excellent way to lower energy costs!

If there’s one thing that small businesses have in common with large corporations, it’s the need to manage costs. Some businesses experience cyclical periods of prosperity, followed by lean times during the off-season. Other companies that are fortunate enough to experience steady business year-round have to pay close attention to their competitor’s prices to ensure their continued success. Utilities are one of your most predictable expenses, and a little belt-tightening can make a large difference. National Custom Hollow Metal offers custom-built two-part kerf frames that can help you lower your overall energy consumption, and we can give you a quote in two hours or less!
