5. Benefits
A key benefit to using IRVING
is our fabrication operations that
allow you to customized your grating to
your plans and specs.
IRVING warrantees the quality of
Its products and the proper
application of it. It also offers a
broad range of steel grating types for
every need.
The fabrication of grating, backed by
a department of highly trained
engineers, has turned IRVING into 4
the manufacturer of choice for grating.
Fabricated grating has been used in
complex constructions,
such as: the ventilation system of
the Mexico City subway, the heliport
in Hotel Nikko, the Mexico City
International Airport, cement
factories, off-shore oil platforms and
other large projects throughout Mexico
and the world.
We are capable of working with
Customized projects of nearly any
shape, cut or other detail. Our
engineering department will assess
the application, necessary supports
and load requirements and will
recommend the best type and shape of
grating for the job.

6. Strong but light
Our grating is light and strong. It is the
most efficient option for flooring due to its
economical cost, and lower weight per
Advantages square meter.
Light and ventilation
Used as industrial flooring, grating allows
light and air to pass through from one floor
to the other, which will lower your energy
costs.
Installation
Installation of grating is very easy and is
made even more. So when fabricated to
the specific customized needs of
our customers.
Safety
Our grating enhances work area safety,
5
due to the elimination of standing liquids
which helps prevent slippery areas that
can cause accidents. We recommend
serrated grating for areas where liquids or
oils are handled.
Durability
Do to its design, its manufacturing process,
and the quality of its materials, IRVING
grating needs very little maintenance, and
will give you years of service.
When installed in corrosive environments,
we suggest hot-dipped galvanized grating
or stainless steel grating in order to
prolong durability. Our sales department
can recommend the best option for your
needs.
Quality and warranty
IRVING grating is subject to the most
stringent quality control, and has a one-
year warranty if used as described in this
catalog.

7. Product Description
IRVING smooth welded grating is
made of bar that can vary in width and
IRVING Smooth thickness depending on the load the
Welded Grating grating will be subject to, and to the
area they will cover. The bars are
joined by several cold-processed and
cold-cut cross-rods (stiffeners), that
forms the shape of a skewed square.
The joint between the bar and the
cross-rod is achieved by means of an
electrowelding process, ensuring the
fusion of each joint.
Technical properties and strength
The width of the bar is determined by
the stress it will be exposed to. The
cross-rods strengthen the bar and keep 6
it from buckling and flexing, when loads
are placed on it.

8. Product Description
IRVING serrated welded grating has the same
features and specifications that smooth welded
grating has, except that it is manufactured with
IRVING serrated serrated bars that provide an antiskid surface
Welded grating
Technical properties and strength
This type of grating is manufactured in various
bars widths and thicknesses to withstand
different types of loads. Serrated grating offers
maximum protection in slippery areas that help
keep shoes, boots
and tires from slipping. They provide better
grip in areas prone toe spills.

9. Product Description
IRVING heavy-duty welded grating is
designed to withstand static or rolling
loads. It is used mainly for heavy-duty
IRVING Heavy Traffic vehicles, including Airplanes.
Welded Grating
Technical properties and strength
IRVING heavy-duty grating has load bars
with widths from 50.8 mm (2”) to 101.6 mm
(4”) and thicknesses of 6 mm (1/4”), 7.9
mm (5/16”) or 9.5 mm (3/8”). The cross
rods used have a diameter of 9.5mm (3/8)
to 12.7 mm (½”).
Finishing bars
We recommend the use of finishing bars
for grating subject to rolling loads, as well
as for heavy-duty grating, because these
bars provide better strength and rigidity.
The official loads H10, H15, H20 8
established by the AASTHO* are the
basis for the design of this type of grating.
Rolling load
H 10 4,717.36 kg (10” x 10” footprint)
H- 15 7,076.04 kg (15” x 15” footprint)
H 20 9,434.72 kg (20” x 20” footprint)
Impact factor is 30%
Load distribution method
Each tire distributed over a width of 10”
(H10): 15” (H15); 20” (H20) two times, plus
the distance centerline to centerline of the
bars over a length in each rod equal to 10”

12. Product Description
IRVING stainless steel welded grating
IRVING Stainless Steel has the
same design of those made from carbon
welded grating steel. It is made of bars in varying widths
and thicknesses, based on the load it will
support, and the area it will cover. The
bars are joined by cross-rods (stiffeners).
The standard panels are 0.995 x 3.00 m
Technical properties and strength
The stainless steel welded grating is
manufactured in various widths, from
3/4” up to 2 1/2”, and bar thicknesses
from 1/8 or 3/16”, and can withstand
different types of loads, depending on
the bar width.
This product is recommended when 11
both resistance to corrosion and strength
are of vital.
Resistance to the environment
Because of its composition in T-304 and
T-316 stainless steel, this grating offers
the maximum resistance to corrosion
with no additional coating needed.
Applications:
•Food processing companies
•Kitchens
•Reactors
•Laboratories
•Vehicle manufacturing plants
•Petrochemical plants
•Water treatment plants, as well as
others

14. IRVING steps are available in:
STAIRSTEPS •Carbon Steel
•Stainless Steel *
*special fabrication
The steps are based on the IS-01 and
IS-06 type Grating. The steps are made
of a front piece made of antiskid plate,
and two side fastener plates.
For emergency ladders and to allow the
use of high-healed footwear, an antiskid
plate is added to the top of the step.
Finishes include:
Natural
Black water-based paint
Hot-dip galvanizing 13
Technical Specs
The maximum length of a step is
determined by the deflection caused by
a 133 kg load concentrated in the center
of the step and at a distance of 127 mm
from the front. The deflection must not
exceed 1/240 of its length.
Applications
Recommended for staircases requiring
maximum safety, and for emergency
stairs. The antiskid surface helps
diminish slips and falls.
