Structural Steel Mezzanines
Properties of Structural Steel Mezzanines:
Understructure of Structural
Steel Mezzanines:
Hot Rolled Structural I-Beams,
Open Web Bar Joists, Tubular Columns, Structural I-Beam Columns
Mezzanine Stairs, Gates, and
Handrail:
Common Stairs for structural steel mezzanines: OSHA and BOCA.
Common Handrail for structural steel mezzanines:
Horizontal 2 and 3 Rail, Baluster Handrail, Solid Panel
Handrail.
Common Gates for structural steel mezzanines: Lift Out, Swing, and Sliding
Gates.
Decking Options for
Structural Steel Mezzanines:
Common
varieties of decking for structural steel mezzanines: B-Deck and Plywood, Bar Grating, Plank Decking,
Concrete and Diamond Plate Steel.
Finishes for Structural Steel
Mezzanines:
Wet Paint,
Powder Coat, Epoxy, Urethane, Hot Dipped Galvanized.
Benefits of
Structural Steel Mezzanines:
Structural steel mezzanines allow for a much greater column
spacing than any other mezzanine system. Electrical
conduit, water pipes etc. can be easily run through open web bar
joists. Open web bar joist give a much more "open feel"
than standard beams, giving the illusion of more clear height.
Structural I-beams can be used to minimize the "deck profile" of
mezzanines.
Drawbacks of Structural Steel
Mezzanines:
Structural steel mezzanines are much heavier than most other
systems so will have a higher dead load and a higher floor load.
The increased weight will also increase freight cost from
factory. Structural steel mezzanines have a rougher finish
than any other mezzanines.

Cold Rolled Steel Mezzanines
Cold Rolled Steel Mezzanines
Properties of Cold Rolled Steel
Mezzanines:
Understructure of Cold Rolled
Steel Mezzanines:
Sheet metal bent to a c-channel in a break press. Tubular
steel columns or tapered columns.
Mezzanine Stairs, Gates, and
Handrail:
Common Stairs for cold rolled steel mezzanines: OSHA and BOCA.
Common Handrail for cold rolled steel mezzanines:
Horizontal 2 and 3 Rail, Baluster Handrail, Solid Panel
Handrail.
Common Gates for cold rolled steel mezzanines: Lift Out, Swing, and Sliding
Gates.
Decking Options for Cold
Rolled Steel Mezzanines:
Common
varieties of decking for cold rolled steel mezzanines: B-Deck and Plywood, Bar Grating, Plank Decking.
Finishes for Cold Rolled
Steel Mezzanines:
Wet Paint,
Powder Coat, Pre-Galvanized.
Benefits of Cold
Rolled Steel Mezzanines:
Cold Rolled Steel Mezzanines are made from sheet metal so they
are much lighter than structural steel mezzanines. Cold
rolled steel also has a very smooth finish so they can be easily
used in "display" applications or public buildings. Cold
rolled steel can be pre-galvanized and this offers a substantial
savings over hot dipped galvanized, stainless steel or aluminum
mezzanines.
Drawbacks of Cold
Rolled Steel Mezzanines:
Cold Rolled Steel Mezzanine Systems are very limited in column
spacing, usually 10' -15' and generally no more than 20'.
Cold rolled steel mezzanines can reach all common live load
capacities, but are unable to reach the high live loads or
heavily concentrated point loads.

Stainless Steel Mezzanines
Stainless Steel Mezzanines
Properties of Stainless Steel Mezzanines:
Understructure of Stainless
Steel Mezzanines:
Sheet metal bent to a c-channel in a break press. Tubular
steel columns.
Mezzanine Stairs, Gates, and
Handrail:
Common Stairs for stainless steel mezzanines: OSHA and BOCA.
Common Handrail for stainless steel mezzanines:
Horizontal 2 and 3 Rail, Solid Panel Handrail.
Common
Gates for stainless steel mezzanines: Lift Out, Swing, and Sliding Gates.
Decking Options for Stainless
Steel Mezzanines:
Common
varieties of decking for stainless steel mezzanines: Bar Grating, Stainless Diamond Plate Steel, Plank
Decking.
Finishes for Stainless Steel
Mezzanines:
None per se, Stainless
Steel.
Benefits of
Stainless Steel Mezzanines:
Stainless steel mezzanines are highly resistive to wet
environments, most chemicals and stainless steel is a FDA approved surface. The latter being
the largest benefit. They are generally designed for easy
wash down and are commonly put in food, or other FDA regulated,
processing plants.
Drawbacks of
Stainless Steel Mezzanines:
MONEY; stainless steel mezzanines are very expensive, very expensive!
Stainless steel mezzanines are restricted to smaller column
spans, generally 10' - 20' max.

Aluminum Mezzanines
Aluminum Mezzanines
Properties of Aluminum Mezzanines:
Understructure of Aluminum
Mezzanines:
Extruded aluminum C-Channels or I-Beams. Tubular Aluminum
Columns.
Mezzanine Stairs, Gates, and
Handrail:
Common Stairs for aluminum mezzanines: OSHA and BOCA.
Common Handrail for aluminum mezzanines:
Horizontal 2 and 3 Rail.
Common Gates for aluminum mezzanines: Lift Out, Swing,
and Sliding Gates.
Decking Options for Aluminum
Mezzanines:
Common
varieties of decking for aluminum mezzanines: Aluminum Plank Grating, Fiberglass Bar Grating.
Finishes for Aluminum
Mezzanines:
Anodized
Aluminum.
Benefits of Aluminum
Mezzanines:
Aluminum, like fiberglass, is impervious to rust. Aluminum
mezzanines can be safely immersed in water without worry.
Aluminum is also very light so many smaller mobile work
platforms are made from aluminum.
Drawbacks of
Aluminum Mezzanines:
Aluminum is not nearly as strong as steel so it is generally not
used to support heavy loads. The column spans are
decreased to around 10' max.
Aluminum mezzanines are also about 3-5 times more expensive than steel!

Structural Fiberglass Mezzanines
Structural Fiberglass Mezzanines
Properties of Structural Fiberglass Mezzanines:
Understructure of Structural
Fiberglass Mezzanines:
Structural fiberglass shapes that are generally pultruded.
Structural fiberglass I-beam columns
Mezzanine Stairs, Gates, and
Handrail:
Common Stairs for structural fiberglass mezzanines: OSHA and BOCA.
Common Handrail for structural fiberglass mezzanines:
Horizontal 2 and 3 Rail.
Common Gates for structural fiberglass mezzanines: Lift Out, Swing,
and Sliding Gates.
Decking Options for
Structural Fiberglass Mezzanines:
Common
varieties of decking for structural fiberglass mezzanines: Fiberglass Bar Grating.
Finishes for Structural
Fiberglass Mezzanines:
Smooth
Fiberglass.
Benefits of
Structural Fiberglass Mezzanines:
Fiberglass mezzanines won't rust or contaminate. They can be immersed
in water and easily washed down. Structural fiberglass
color won't ever "chip off" because it is molded into the
fiberglass.
Drawbacks of
Structural Fiberglass Mezzanines:
Fiberglass mezzanines are much more expensive than their steel
counterparts ( usually 2-3x). Fiberglass systems have more
"give" than steel, components such as handrail sway a
bit.

Rack Supported Mezzanines
Rack Supported Mezzanines
Properties of Rack Supported Mezzanines:
Understructure of Rack Supported
Mezzanines:
Pallet rack or heavy duty shelving
Mezzanine Stairs, Gates, and
Handrail:
Common Stairs for rack supported mezzanines: OSHA and BOCA.
Common Handrail for rack supported mezzanines:
Horizontal 2 and 3 Rail.
Common Gates for rack supported mezzanines: generally no gates
but any gate will work, usually material lifts are used to
transport product from floor to mezzanine.
Decking Options for Rack
Supported Mezzanines:
Common
varieties of decking for rack supported mezzanines: B-Deck and Plywood, Bar Grating, Plank Decking.
Finishes for Rack Supported
Mezzanines:
Generally
speaking, shelving and pallet rack have a wet paint or powder
coat paint finish.
Benefits of Rack
Supported Mezzanines:
Shelving / rack supported mezzanines or "catwalk systems" are
designed for high density storage. They are very cost
effective, combining the storage and the structure into one
unit.
Drawbacks of Rack
Supported Mezzanines:
Once the mezzanine is up and installed it is very difficult to
rearrange the layout. Mezzanine shelf heights can be easily changed
but that's about it.
