Fibergrate Composite Structures is the originator of molded PP
fiberglass reinforced plastic(FRP)grating. Fibergrate continues to ' s
lead the industry in innovative products and the ability to provide
customized solutions for numerous applications and industries.
In our 40 year history,Fibergrate has provided many products to �.
marine,recreational,and commercial customers. Now as our nation
has become more knowledgeable about our marine environments,
we have committed to producing products that will provide the best
solution for our customer and the environment.
Seagrasses are widely recognized as one of the most productive ,
and valuable habitats in the shallowmarine environment.Although
the area of the seagrass loss associated with an individual dock is
9 Y :a
relatively small,cumulative impacts and fragmentation of seagrass
beds may be significant along highly developed shorelines.With =-rlFn
seagrass populations in decline in many areas,coastal resource
managers are interested in products to reduce additional dock-
associated impacts to an already stressed resource.
Fibergrate's Micro-Mesh'grating has an open area of 44.4%and
exceeds guidelines set forth by the Army Corp of Engineers who
require a minimum open area of 43%.The open area consideration
is an important factor in protecting the seagrass as it allows light
penetration through the dock. In addition,our square top mesh V
provides a maximum opening of 3/4"so it also meets the Americans ,
with Disabilities Act(ADA)guidelines making it an excellent choice �` =
for public area applications.Offered in a 4'x 12' panel and depth
options of 1"and 1-1/2",this bi-directional grating ensures a safe,a
long lasting,easy to install and maintain solution. .. :.:. ... .:

NOTES:
1.Functionality of grating is limited to MAXIMUM RECOMMENDED LOAD.The designer should not exceed this MAXIMUM RECOMMENDED LOAD at any given span.
2.ULTIMATE CAPACITY represents a complete and total failure of the grating.Values are provided to illustrate the reserve strength of the grating at a given span and are NOT to be used for design.Functionality of grating
Is limited to MAX RECOMMENDED LOAD.
3.Walking loads,typically 50-65 psf maximum are recommended for pedestrian traffic.Deflections for worker comfort are typically limited to the lesser of 318"or CLEAR SPAN divided by 125;for a firmer feel,limit deflection
to the lesser of 114°or CLEAR SPAN divided by 200.
4.The allowable loads in this table are for STATIC LOAD CONDITIONS at ambient temperatures only.Allowable loads for impact or dynamic conditions should be a maximum of ONE-HALF the values shown.Long-term
loads wiil result in added deflection due to creep in the material and will also require higher safety factors to ensure acceptable performance.For applications at elevated temperatures,consult factory.The designer is
further referenced to ASCE Structural Plastics Design Manual.
5.All gratings were tested in accordance with the proposed standard of the Fiberglass Grating Manufacturers Council of the American Composites Manufacturers Association(ACMA).
