Commercial Grade - 20 Gauge Steel Door & 16 Gauge Steel Frame
Universal Fireproof hollow metal doors are manufactured per order and designed specifically for use on commercial buildings. When we say commercial grade, we mean it. our doors are manufactured from thick 20 gauge heavy duty steel and the door frames are constructed from 16 gauge steel. This is the industry standard for any hollow metal door and frame used in any commercial building and it offers the best security. Unfortunately, there are many residential grade hollow metal doors on the market today being advertised as commercial grade. Many of these residential grade steel doors purposely do not specify the gauge of steel the door is constructed from. The harsh reality is that if the door's steel gauge is not advertised or listed, then it is most likely constructed from thin 24 or 26 gauge steel with no insulated core and designed for residential light duty homes. When residential steel doors are installed in a commercial building this results in the metal doors denting and deforming within days of installation. Not to mention, the thin gauge residential grade steel provides much less security than a commercial grade 20 gauge steel door. You will not have this issue with our hollow metal door system. Universal hollow metal doors feature heavy duty 20 gauge steel with an insulated honeycomb core, lock reinforcement, and hinge reinforcement. Our frames are designed using 16 gauge steel so they will not bend or dent easily.
Best Value For Security
Universal hollow metal doors are ideal for security doors. Unlike wood or aluminum glass doors, steel doors can provide much more security and durability. Wood doors often crack and storefront glass doors are vulnerable to broken glass. If your commercial building is in an area that is subject to abuse or break ins, the Universal commercial steel door is your best option with the best value. The heavy duty steel door construction and frame is much more durable than aluminum or wood. Steel doors also have a much higher impact resistance than commercial wood or storefront doors.
Energy Efficient
Our hollow metal steel doors come standard with an insulated honeycomb core. This core type helps retain your commercial building's energy.
