1 As most building project managers know, the Warnock Hersey and Underwriters Laboratories Mark are North America’s top safety and performance marks used for building and construction products. Not just a label, it indicates compliance with applicable building codes, association criteria, and product safety and performance standards. The WH and UL Mark reflects NCHM’s commitment to the safety, performance, and quality of our products, which maintain compliance through ongoing site inspections.

2 Our extensive door product line includes certified labeling for 20-minute, 3/4 hour, 1-1/2-hour, and 3-hour fire ratings. Label doors are reinforced with honeycomb, polystyrene or steel stiffened cores permanently bonded to the inside face sheets. They can be made up to a maximum size of 4 feet wide, 8 feet high for a single door, and 6 feet and 8 inches wide, 8 feet high for a pair of doors. We also provide fire rated frames for a variety of doors.

3 NCHM offers a wide range of custom-crafted stainless steel and galvanneal metal doors and frames to accommodate any project plan. We choose superior, durable materials and expertly craft our products to precise tolerances and exact specifications for many applications, including heavy-duty industrial environments, medical facilities, retail spaces, and more.

4 We can also expedite your building schedule. Not only do we offer industry-leading turnaround times for your orders, we make every effort to make sure our products arrive at your jobsite in perfect condition. We meticulously wrap doors and frames in impact-absorbing materials and carefully package them in heavy-duty wooden crates.
