 Do you need a 3-hour fire rated door, 1 & half hour fire rated door or three-quarters of an hour fire rated door? Mesker Door carries all three. Did you know that your steel door fire rating needs to be at least three-quarters of your wall fire rating? 

Honeycomb-The honeycomb shaped inner core material is made from layers of paper or cardboard,bonded together in parallel and uniformly spaced provide support and rigidity. When it is expanded for use, it forms a honeycomb configuration with hexagonal cells. It is manufactured from recycled paper and generally is non-toxic. The honeycomb sheets can be made of various thicknesses and cell sizes to cater for a variety of applications. It can replace the solid filling materials used in solid core doors.

The following are features of Honeycomb cores:
• Light weight and easy to handle
• Less hinges needed for hanging panel
• Allows flexibility in design and shapes
• Possible to make tall and thin panel
• Economical



Urethane- Popular for exterior doors. Higher density the urethane material is, the greater its strength and stability. The forming of insulation in a door is by injecting a liquid between the steel skins that make up the door. As the liquid insulation is in contact with the air, it begins to expand and harden. As it does this, all of the cracks and creavices get filled in and  it becomes semi hardened and very dense. The insulation will actually adhere to the metal of the door, increasing the strength of the door. The best comparison is that the polyurethane insulated door is similar to a refrigerator door. 



Polystyrene-It is the most common style of door. It can be used interiorly and externally. This Is a Foamed style of insulation that gets inserted into the door skin by using adhesives on (glued). 



Fiberboard-MDF or medium density fiberboard is an engineered material made from wood fibers pressed tightly together and combined with glue binders. Many interior doors are made from MDF. The beauty of MDF is that it's a stable material and isn't susceptible to bowing or twisting like real wood. It's also easily molded and machined which allows manufacturers to include detailing that looks very similar to the kind you see on real wood doors. Raised panel and mission style doors to name a few are easily reproduced using MDF.

MDF is a good choice if you're going to paint your doors since you're not going to see any wood grain (because MDF doors don't have a wood grain). That brings the cost down relative to a similar-sized/detailed wood door.



Bullet-resistant Door-
Our 14 gauge, bullet-resistant assembly is constructed identically to our standard Mesker N-Series doorexcept for an additional backup plate welded to the inside face of the pan. It’s designed to deflect, atclose range, Level 3 SPSA ammunition.
• Available in sizes up to 4’-0” x 10’-0”.
• Bullet-resistant doors can be fire-rated 20 minute
to 3 hour per the same specifications as the N-Series
Door listed above.
• Assemblies have an approved rating of Level III by
Underwriters Laboratory. Level IV and V can be
custom ordered upon request.



Different Frames:

Masonry Frames (F-series)-
The standard F-series masonry frame is the best stock hollow metal assembly in the industry. In fact, we have proven our caliber for more than 145 years — a testament to our craftsmanship. We use only the best materials, like 16 or 14 gauge cold rolled steel, or A60 Galvannealed steel for corrosive applications. State-of-the-art technology is employed for consistent and accurate quality, such as our computer-controlled mig welders. Mesker surpasses the industry requirements by using 3/16 inch hinge reinforcements to outlast the heaviest doors. All our F-series frames are fire-rated 3 hour and receive a embossed UL or Factory Mutual label.

Drywall Jamb Frames (FDJ-series)-
There is a major difference in our FDJ-series drywall frame when compared with other competitors. We use only 16 gauge cold-rolled or A60 Galvannealed steel, not the weaker gauges marketed by many competitors. Our heavy gauge frames are designed to be pressure-fitted to the wall which improves unit life, and ensures durability with less torsion and sagging. Because we use heavier gauge steel for our frame, stronger 3/16 inch hinge reinforcements can be welded to the rigid structure to hang heavier wood or metal doors.
Average installation time is 4-5 minutes per frame using our adjustable jamb lock for secure
anchoring. Additionally, two dimpled holes at the base of each jamb stabilize the frame during installation. All our FDJ-series frames are fire-rated 1-1/2 hour and receive a embossed UL or Factory Mutual label.
Remodeling Frames-
Mesker remodeling units are ideal for any existing wall structure. Comprised of six individual components, they are formed from rigid, 16 or 14 gauge steel, and can be ordered in an array of profiles and jamb depths. An individual header, hinge jamb, strike jamb, and the counterpart trim sections help the installer to make an adjustable, custom fit for each opening.
A welded-in,16-gauge floor anchor and eight countersunk, jamb holes for fastening to side walls hasten installation.
• Available Fire Rated up to 90 Minutes
