Equal SPAN (in.) Equal Pultruded 2. The designer should not exceed MAXIMUM RECOMMENDED load at any time. MAXIMUM LOAD represents a factor of safety of 4:1 for molded grating and 2:1 for pultruded grating on ULTIMATE CAPACITY. ULTIMATE CAPACITY represents MAX LOAD observed at initial fracture. Uniform Equal SPAN (in.) Molded Equal Walking loads for maintenance traffic are typically a live load of 50 PSF. Deflections for worker comfort are typically limited to (3/8 ) or SPAN divided by 120 under full live load. For a firmer feel under full live load or a line load 250 lbs/ft of width, limit deflections to 0.25 (1/4 ) or SPAN divided by 200. SPAN Pultruded 4. The loads represented are for STATIC LOAD CONDITIONS at ambient temperature. Deflections for impact loads or dynamic loads will MULTIPLY the deflections shown by 2. Long term loads will result in added deflection due to creep in the material and will require higher factors of safety to ensure acceptable performance. SPAN Deflections are limited to 0.5 (1/2 ) as recommended by the Fiberglass Grating Manufacturers Council of the American Composites Manufacturers Association. 2 (800) marcospecialtysteel.com

5 MOLDED PRODUCTS Marco Fiberglass sets the standard for fiberglass reinforced plastic (FRP) molded products, combining unmatched corrosion resistance with high strength, long life and safety. Marco products are proven to deliver years of reliable service, even in the most demanding corrosive conditions. Marco Fiberglass products are also lightweight, easy to fabricate and easy to install. Savings on labor and equipment often make the total installed cost of Marco Fiberglass products less than that of steel. Combining these installation savings with low maintenance, long life and worker safety, Marco Fiberglass products offer a total life cycle cost that is significantly lower than that of metal grating products. Molded Options Molded Surfaces Phenolic (Type P) Best choice for applications where fire resistance, low smoke, and low toxic fume emissions are critical. Typical applications include: offshore & onshore oil refineries, tunnels, ships and train decks. The Grating has passed the USCG Test for level 2 Performance. Vinyl Ester (Type V) Developed to withstand frequent and direct contact in the harshest of chemical environments. Type V is ideal for use in acidic and caustic environments such as chemical plants, waste treatment, and plating applications. Isophthalic Polyester (Type I) Industrial grade resin great for environments where fiberglass may occasionally be in contact with harsh chemicals due to splashes or spills. Meniscus Top: The concave surface of Marco Fiberglass meniscus top grating provides superior slip resistant footing in most environments including wet or oily conditions and is the standard surface for all Marco molded gratings. Food Grade Isophthalic Polyester (Type F) Ideal for environments in the food and beverage industry where fiberglass grating may frequently be wet or exposed to harsh cleaning products. General Purpose Ortho Polyester (Type O) A good general purpose resin great for environments such as food processing plants, dairies, and walkway applications.

Rubber Feet for Molded Grating Sealing and Bonding Kits Specially designed rubber feet are an economical way to create a raised, ergonomic grating workmat for use around machines, lathes and in wet areas. With the rubber feet, facilities have a cost-effective solution to elevate grating needed for drainage or waterflow and safe, ergonomic platforms. The feet raise the grating 1/2 above the ground, and along with the open mesh, protect workers by allowing chips and fluids to fall below the standing surface eliminating slip and fall hazards. To maintain corrosion resistance and structural integrity, Marco Fiberglass offers standard resin sealing in 1/2 pint and gallon kits for protecting the exposed ends of cut panels and other components. One 1/2 pint kit coats approximately lineal feet. Sealing and bonding kits come in a natural, unpigmented color. (800) marcospecialtysteel.com 19

22 Accessories Handrails Systems Handrails systems are offered in one of three system designs by Marco Fiberglass: Heavy Duty Handrail System, our Standard Duty Handrail System and our Light Duty Handrail System. All systems exceed OSHA requirements for handrail systems. While some provide much stronger resistance to loading conditions, all of Marco s handrail systems offer corrosion resistant and maintenance free service at a competitive price. Choose from one of these Marco handrail systems, depending upon the severity of the service environment. All Marco Fiberglass Ladders are designed for ease of fabrication and installation, while offering the maximum in corrosion resistance. All systems exceed OSHA requirements for handrail systems. Ladder Systems Marco Fiberglass has engineered and offers two basic ladder systems. Our Standard Fiberglass Ladder offers the necessary rigidity and safety when structural stand-off supports are capable of being provided at regular and close intervals. However, in some cases, stand-off supports cannot be provided at regular intervals, thus requiring the ladder to span much longer distances. In order to comply with OSHA standards for ladder safety and design, Marco offers our Stiffened Ladder to meet these needs. All Ladders are designed for ease of fabrication and installation, while offering the maximum in corrosion resistance. Of course, all ladder systems are equipped with safety cages when required. Structural Shapes Marco Fiberglass offers a wide range of fiberglass structural shapes. These fiberglass shapes are offered in isophthalic polyester resins and vinyl ester resins, but can also be provided in acrylics and phenolics. Wide flanged beams, I-beams, angles, channels, square and round tubes, solid shapes, custom shapes, threaded rod, nuts, and other FRP products are provided as a complete and comprehensive alternative to conventional steel, wood and aluminum construction. Because Fiberglass structures are lightweight, electrically and thermally non-conductive, and corrosion resistant, they are fast becoming the construction material of choice in many applications. 20 (800) marcospecialtysteel.com
