What Goes Into Making a Krieger Door
Not all doors are created equal.
See why Krieger’s hollow metal doors are superior to standard wood doors.
Superior Interior Construction
Wood Rails
No Vertical Supports
Wood Lock Box
Standard Wood Door
With no vertical supports and only a wood underlying construction, standard wood doors are prone to sagging, warping, and damage upon impact.
Steel Frame
Vertical Steel Supports
Steel Lock Box
Krieger Door
Krieger doors are built with steel frames, vertical channel supports, and lock boxes, a combination that offers exceptional strength and security. To ensure durability, Krieger doors undergo impact, static load, and rack testing.
High-Performance Core
Only Light Weight Core Material
Standard Wood Door
Typically, standard wood doors can only be filled with lightweight sound-deadening material because the internal structure isn’t strong enough to support any other core material.
Core Materials as Needed to Achieve Performance
Krieger Door
Krieger hollow metal doors can be manufactured using a wide range of core materials to meet special purpose performance needs, including acoustical, bullet and blast resistance, radio frequency shielding, and more.
Exterior Strength and Durability
Thin Veneer Applied to Cover the Core
Standard Wood Door
Standard wood doors are simply covered with a thin veneer, which provides no added strength. Because of this inherent weakness, the doors cannot achieve higher acoustical, security, and fire ratings.

Steel Skin

Custom Finishes to Match Your Project
Krieger Door
Krieger doors come standard with a 16-gauge or 14-gauge steel skin built to withstand a lifetime of heavy use without showing wear and tear. This unique design enables the door to achieve higher acoustical, security, fire, and other specialized ratings.

The application of a 3-ply veneer allows for stronger adhesion, easier maintenance, and customized finishes.
Acoustical & SCIF
Krieger's acoustical doors and sound control windows, are used in premier live performance venues and industrial applications where noise and sound control is of primary concern.
