At National Custom Hollow Metal Doors & Frames (NCHM), we strive for excellence from beginning to end in our manufacturing process, with one of the most important factors being safety. You’ll find our fire rated doors to be of the utmost quality.

Every building project, large and small, must meet local fire codes. NCHM’s team has four decades of experience ensuring our products meet and often exceed industry standards for safety. Our clients always have peace of mind knowing that our steel commercial (security) doors are up to code and properly labeled.

1 Our hollow metal doors are primarily labeled Intertek Warnock Hersey (WH) as well as the UL Mark, offering 20-minute, 3/4-hour, 1-1/2-hour and 3-hour fire rated doors. We build them with 3 types of cores, Steel Stiffened, honeycomb and polystyrene permanently bonded to the inside face sheets. These fire door certification labels are fully recognized throughout the industry by the IBC and all local code officials in North America.

2 These labels on our products reflect NCHM’s commitment to product safety, performance and quality to inspectors, builders and end users. The mark also denotes that we undergo follow-up inspections to make sure we continue to comply with necessary product manufacturing standards.
