The average city dweller or suburbanite is bombarded with a cacophony of sounds each day, and we all do our best to tune them out. Sustained exposure to noise levels greater than 70 dB can cause permanent hearing loss, and we’re routinely exposed to noises of over 100 dB near airports, construction sites, and other high-traffic areas. Excessive noise increases our stress levels, and it can also negatively impact workers’ productivity. But our team at National Custom Hollow Metal is here to help, and we can give you a quote for Sound Safe Sound Transmission Control (STC) doors in two hours or less!
Safe Shot Ballistic doors offer the protection you need from gun violence!
Most Americans couldn’t imagine living anywhere else in the world, but that doesn’t change the fact that our nation leads the world in gun violence. Americans are 26 times more likely to be shot than citizens of other industrialized, high-income countries, and the only thing that most victims seem to have in common is that they never saw the attack coming. But our team at National Custom Hollow Metal is here to help you keep your workers and customers safe, and we proudly offer custom-built Safe Shot Level 3 Ballistic doors that can stop a .44 Magnum round!

Kerf frames are an excellent way to combat rising energy costs!
Utility companies have the power to raise rates as they see fit, and the only way to fight back is by reducing your energy consumption. This is often easier said than done, but you should start by identifying areas where energy is wasted. If you feel a draft around exterior doors when they’re closed, you’re paying more than you should to maintain your desired indoor temperature, and the extra costs can really start adding up! But the good news is that weatherstripping can make a huge difference, and our team at National Custom Hollow Metal is ready to give you a same-day quote for two-part kerf frames!
