People living and working in urban communities understand that the price of big-city convenience is dealing with large crowds and traffic jams at the beginning and end of each day. Suburban areas can also get crowded, and our only choice seems to be to learn how to be more patient and tune out the cacophony of noise we encounter everywhere we go. But that’s not good enough in certain situations, and National Custom Hollow Metal proudly offers custom-built Sound Transmission Control (STC) doors with superior noise reduction capabilities!

We’ve been manufacturing custom-built stainless steel doors and frames in the USA for over 50 years and are ready to give you a same-day quote. Our STC doors feature a proprietary acoustic core with advanced noise suppression technology and can be configured as single or pair entry as a complete installation-ready assembly. STC doors are an ideal option for recording studios, auditoriums, or any place where you’re interested in controlling ambient noise. All units come as an assembly package, including door, frame, hinges, gasketing seals, flat thresholds, and door bottoms of either a brush sweep type or retractable auto door bottom.

STC ratings range from 20 to 60 and measure a door’s noise suppression capabilities. We manufacture doors with an STC rating of 51 in any size up to 4’ x 8’, and they have the ability to make human voices virtually inaudible. Many firms install STC doors in conference rooms and boardrooms to keep meetings completely confidential, and they’re a great way to keep the sounds of traffic, construction, landscaping, and approaching aircraft outside where they belong!

All NCHM orders include Quik Ship service at no additional charge, and we also offer Hot Rush timetables of 5-10 days for limited quantity orders. Let us know when and where you need your doors shipped, and we’ll take care of the rest. Our STC doors are subjected to a rigorous multi-point inspection before shipping, and you can order with confidence because we stand behind all NCHM orders with a one-year warranty!
