STC Doors & Frames are the key to a quiet workplace, and we’re ready to give you a same-day quote!
Individuals who work in airports, factories, and on construction sites are accustomed to wearing hearing protection, but most of us are exposed to dangerous noise levels nearly everywhere we go! The typical city dweller or suburbanite is routinely exposed to noise levels of 50 to 70 decibels (dBA), and levels can reach 110 dBA near construction zones, airports, and highways. Excessive workplace noise has a detrimental effect on worker productivity and accuracy, and sustained exposure to 85 dBA or higher can cause permanent hearing loss.
Safe Shot Ballistic doors protect your most important asset: Your people!
Business owners and managers are responsible for the safety of their customers and their employees, and they should have a plan in place for every possible worst-case scenario. America leads the world in gun violence, and its citizens are 26 times more likely to be shot than citizens of other industrialized, high-income countries. No one likes to imagine an armed gunman bursting through their doors, but our team at National Custom Hollow Metal is here to ensure you’re prepared in that highly unlikely scenario. We proudly offer custom-built Safe Shot Level 3 Ballistic Doors and Frames that can stop a .44 magnum round, and we’re ready to give you a same-day quote!
