FABCOGRATE FRP GRATING & FABCORAIL FRP SAFETY RAILING

FABCO PHENOLIC GRATING Phenolic grating is a dramatic innovation for markets where fire safety is a major concern; it offers superior resistance to flame and high temperature with low emissions of smoke and toxic fumes. The nonflammable nature of phenolics enable phenolic grating to withstand higher temperatures than polyester or vinyl ester for extended periods of time without major structural damage�

FABCORAIL FRP SAFETY RAILING Our Safety Railing is fabricated from structural FRP components manufactured by the pultrusion process� Fabco Plastics stocks a wide variety of Safety Railing which can ship from stock for easy on-site assembly� Our standard handrail is a 2-rail system manufactured in a “Safety Yellow” color.

Grating Selection Process1. Select the proper bar spacing and height to meet your load requirements.2. Select the proper resin to meet your environmental requirements.3. Select the proper panel size to meet your requirement.4. Determine if you want grit top or plain top.

Deflection to Span Ratios • For a resilient, non-fatiguing, comfortable feel use the STANDARD deflection to span ratio of 1:120. • For an elevated installation, where a solid feeling is desired, use a deflection to span ratio of 1:180 (NBC-85).

A deflection to span ratio greater than 1:100 (1%) is not recommended. Do not exceed .5” (13mm).

Load Deflection Tables

Panel Installation • Panels are designed to be supported on all sides. • Use end clips if panel ends cannot be supported. • Use hold down clips to prevent panel drift.

Panel Selection • Determine the type of loading: concentrated or uniform. • Estimate the load and determine the span. • Decide what maximum deflection is appropriate: solid, standard or 1%. • Enter the appropriate 1” (25mm) table. If the deflection is less than the maximum selected, choose the 1”

thickness. It is more economical than 1.5” thick panels. • If the deflection or span is too great for 1” thick panels, select 1.5” thick FRP Grating and design your support

system for the appropriate span. • Select the resin system.

Pultruded Fiberglass Grating

How to Specify DURADEK®Fiberglass grating shall be DURADEK® Series (I-6500 1") (I-6500 1-½") (T-5800 2") as manufactured by Strongwell. Grating shall be pultruded and assembled in the U.S.A. Resin shall be fire retardant (polyester) (vinyl ester) meeting the requirements of a Class 1 rating of 25 or less per ASTM E-84 and the self-extinguishing requirements of ASTM D-635. Color shall be (light gray) (yellow). Resin shall be UV inhibited and the composite shall include a veil on all exposed surfaces. Panels shall be assembled into the sizes ordered using a 3-piece pultruded cross-rod system.The cross-rods shall consist of a center core wedge and two spacer bars that are notched at each bearing bar so that each bearing bar is both mechanically locked and chemically bonded to the web of each bearing bar. The spacer bars shall be continually bonded to the center core wedge. The cross-

DURADEK®

How to Order When ordering DURADEK®, ensure the bearing bars for installation will be oriented in the correct direction for the application. Bearing bars shall traverse from support to support. Cross-rods are not intended to be applied in the span direction. The adjacent drawing will help specify the width and length of panels.NOTE: Width is the measurement from end to end of the cross-rods. Length is always the bearing bar length.Panel Sizes Are Specified: Width x LengthNOTE: DURAGRID®, Strongwell's line of custom pultruded grating, is available with a wide array of options, including: colors, resin systems, panel sizes, cross rod spacings and more.

Nosings for Stair Treads and LandingsDURAGRID® pultruded stair treads and landings are produced by attaching a 2" deep nosing to the leading edge. This gives added strength and rigidity to the area that takes the most impact and abuse. In addition, the nosing provides more surface area for skid resistance, wear and better visibility. Light gray stair treads with yellow nosing are available at additional cost.

USING THE LOAD/DEFLECTION TABLESSeries DesignationThe series designation indicates the bar size and shape and the percent of open area.For example: T-5800 2" means 2" T-bar spaced to give a 58% open area.

Load Table DataDeflection values are based upon minimum apparent modulus (E) per span. Maximum Recommended Load data was calculated by the Strongwell Test Lab. See FGMC/ANSI Grating Manual for additional information regarding apparent modulus deflection.

STATISTICAL REPORTING METHODSMinimum ValueA value that is a specified distance from the average. The most common specified distance is three standard deviations.

Characteristic ValueAs defined by ASTM D7290, a value that is normally between two and three standard deviations from the average.

Average ValueThe sum of a list of values divided by the number of values in the list, without consideration for standard deviations.

Typical ValueNo definition. Not recommended for use by Professional Engineers. Can be any value the manufacturer chooses.

NOTE: Strongwell recommends the use of minimum or characteristic values for design calculations
