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!

We’ve been manufacturing stainless steel doors and frames for five decades and counting, and we can give you a quote in two hours or less! Sound Safe single galvanneal doors feature advanced noise suppression technology and are ideal for recording studios, auditoriums, or any location where you’d like to control ambient noise. Many companies also install STC doors in their boardrooms and conference rooms to ensure confidential information can be discussed without being overheard by individuals walking by! STC ratings range from 20 to 60 and measure the door’s noise suppression capabilities. A door with an STC rating of 20 is effective at filtering out ambient noise, but our custom-built doors have a maximum STC rating of 51, which makes human voices virtually inaudible!

Sound Safe STC doors can be custom-built in any size up to 4’0 x 8’0 and configured as single or pair entry as a complete installation-ready assembly. The assembly includes the door, frame, hinges, gasketing seals, flat thresholds, and door bottoms of either a brush sweep type or retractable auto door bottom. All NCHM orders include Quik Ship service, and we also offer Hot Rush timetables of 5-10 days for limited quantity orders. And you can always order with confidence because we stand behind all of our products with a one-year warranty!
