| Grating
Glossary of Terms |
| The metal fabrication
industry uses a variety of technical
terms. Understanding these terms will
help you to design projects, get prices,
order grating and communicate with others
in the industry.

|
| Materials |
| Steel |
- Lower Cost.
- Nearly the strongest grating
material.
- Industrial appearance.
- Must be coated to withstand
environmental corrosives.
- Common coatings: galvanized
and occasionally paint.
- Scratched coating subjects
grating to serious corrosion,
potentially weakening grating
structurally.
- Not commonly used in highly
corrosive environments.
- Common uses: highway signage,
refinery walkways.
|
| Aluminum |
- Inexpensive.
- Lightweight.
- Conductive.
- Nonmagnetic.
- Aesthetically attractive.
- Can be coated with anodizing
in wide variety of colors
and finishes.
- Used where aesthetic appearance
is important.
- Used in reasonably hostile
environmental conditions such
as sewage treatment plants
and marine uses, depending
on the chemicals used in chemical
plants.
- Withstands acetone and similar
chemicals.
- Does not withstand acids.
|
| Stainless Steel |
- Called the best metal in
the world.
- Strong, durable.
- Rust resistant, heat resistant.
- Aesthetically highly attractive
when finished properly.
- Very expensive.
- Used in hostile environments
and high heat environments.
- Used where aesthetic appearance
is important.
|
| Bronze |
- Seldom used.
- Very heavy.
- Very expensive.
- Very attractive.
- Usually not polished or
coated since most architects
want the bronze to achieve
an aged appearance.
- Used where aesthetic appearance
is important.
|
| Fiberglass |
- Used where steel or aluminum
will be corroded.
- Poor in heat.
- Poor outdoors in sunlight.
- Not particularly strong.
- Difficult to fabricate.
- Withstands acids, does not
withstand acetone and similar
chemicals.
- Used in highly acidic environments,
particularly acids.

| Determining Load |
Specifications generally
require grating to be able to support
a certain amount of weight. This is
called load. Determining load involves
time-tested formulas related to material
used, mesh pattern, and width and span
of the grating. Go to Load
Calculator.
One of the most useful Web Tools on
our website is our grating Load
Calculator. Spend a few minutes
getting familiar with our grating Load
Calculator and you will be able
to determine the appropriate grating
for a given load. |

| Products |
| Rectangular
Aluminum Grating |
|
| We
manufacture lightweight, corrosion
resistant aluminum bar grating.
This grating is the standard product
used in the industry. The bearing
bars are on 1-3/16" centers,
and the cross bars are on 4"
centers. The grating is normally
provided with a mill finish. Additionally,
the grating can be furnished with
bearing bars on 15/16" centers.
Cross bars can be furnished on
2" centers. |
|
|
| I-Bar Aluminum
Grating |
|
| Similar
to Rectangular Aluminum Grating,
I-Bar Grating uses "I"
shaped (when viewed from the end),
aluminum bearing bars, instead
of rectangular shaped bearing
bars. This increases the load
bearing capacity of the grating
and lowers the weight of the grating.
The top, walking surface of I-Bar
Grating can be grooved for improved
foot traction. I-Bar Grating is
often used where the grating will
get wet and may subject pedestrians
to slipping. |
|
|
| Safety Grit |
| Our Safety Grit is an
enhanced "anti-slip" surface,
applied to the top edge of I-Bar Grating.
It consists of #36 sized granules of
aluminum oxide and high density epoxy
compounds. Each granule is encapsulated
by the epoxy and bonded to the top edge
of the grating. Safety Grit has passed
federal abrasion testing and is approved
by Pacific Gas & Electric for use
in high pedestrian traffic areas. Safety
Grit is nearly as tough as a grinding
wheel and outlasts competitive options. |
|
| Extruded Aluminum
Plank Grating |
|
| Our
extruded aluminum plank grating
is strong, lightweight, corrosion
resistant flooring. It is anti-skid,
non-sparking, non-rusting and
anti-magnetic. The 6" sections
can be easily assembled to suit
any particular application. We
furnish plank-type grating with
dovetail interlocks which neatly
slide together or plain edged
sides. An economical substitute
for checkered floor plate grating.
It is stronger and weighs less. |
|
|
| Close Mesh
Grating (All Metals) |
|
| We
manufacture a complete line of
close mesh grating products. The
Americans with Disabilities Act
(ADA), limits all openings in
floors accessible to wheelchair
traffic to 1/2" maximum.
Our close mesh grating products
start at 1/2" clear and narrow
to 1/4". When high heel traffic
is expected, 5/16" clear
openings is the normal design.
Close mesh grating can be made
of aluminum, aluminum I-bar, steel,
stainless steel, bronze, and brass.
The products can be finished by
anodizing, powder coating, galvanizing,
passivating, bead blasting, painting
or polishing. |
|
|
| Stainless Steel Grating |
| The choice to use stainless
steel over other metals is made to take
advantage of the corrosion resistant
properties or to provide aesthetics
that only finished stainless steel can
offer. In the first case, swaged stainless
steel is not subjected to the welding
process and carbide precipitation does
not occur. Carbide precipitation leads
to inner granular corrosion inherent
in welded stainless steel grating. Further,
welding leaves extensive discoloration
and distortion. Swaged stainless steel
grating retains the native color of
the metal without discoloration, and
is not warped from welding. Stainless
steel has superior performance characteristics
for abrasion resistance and heat resistance.
Since stainless steel accepts a variety
of finishes it offers a highly attractive
appearance. |
|
|
| Welded Steel Grating |
| Standard steel grating
has bearing bars at 1-3/16" centers,
and cross bars at 4" centers. Steel
grating is normally painted or galvanized.
Steel grating is a mainstay of the industry.
It is strong and economical to use but
subject to severe corrosion in hostile
environments. Often used as a short-term
solution. |
|
| Stair Treads |
| Virtually every grating
is used to make treads including aluminum,
stainless steel and steel. Additionally,
we manufacture treads from extruded
shapes designed specifically for treads. |
