2 CorGrate Fiberglass Grating When unsurpassed corrosion protection and safety are needed, CorGrate delivers. Countless companies representing a wide range of industries have benefited from the long service life and economy of CorGrate fiberglass grating. In challenging conditions, CorGrate delivers long, safe and reliable performance for pedestrian, and in specific cases, vehicular traffic - conditions where conventional metal grating has a short service life resulting in high replacement costs and unsafe operations. As a leading manufacturer with a broad product line of pultruded and molded sections, CorGrate can provide an FRP grating ideal for virtually any application. Both CorGrate grating types provide outstanding protection against corrosion. Offering higher strength and stiffness, pultruded sections have the advantage in structural performance, with heavy duty sections suitable for tractor and trailer loads (HI Series). Either type of CorGrate is much lighter than its metal counterpart, resulting in reduced weight of structures and significant savings in installation costs. CorGrate manufactures, designs and fabricates complete fiberglass structures that can range from tank loading and walkway platforms to handrails and ladders incorporating FRP grating, structural shapes, handrails and ladders. Designs fully utilize the unique strengths and economies of fiberglass reinforced plastic (FRP) structural shapes. Combining advanced design concepts, automated fabrication and specialized technical assistance CorGrate provides corrosion resistant FRP structures with life cycle cost advantages over protected metal structures. All CorGrate fiberglass products are available as individual components or in complete systems fabricated by CorGrate and designed on state-of-the-art CAD equipment.

3 CorGrate s Value to Users Features Outstanding corrosion resistance, high impact resistance Slip resistance, high strength, non-conductivity Lightweight Resiliency Integral color, corrosion resistance Value Long, low maintenance service life; life cycle cost savings Worker safety, reduced slips and falls Ease of handling; low installation costs; reduced weight of structures Better walking surface; worker comfort Better appearance, reduced maintenance costs Where to use FRP Materials Corrosive Environments - Compared to metals, CorGrate fiberglass materials deliver dramatic cost savings over the material s life for operations involving chemicals or high moisture. In the toughest conditions, FRP materials exhibit long term retention of structural properties for enhanced safety. Critical Weight Areas - FRP s high strength to weight ratio means weigth savings, an added value for applications such as offshore platforms, rooftops and suspended catwalks where weight of the structure is a critical issue. Electrical Areas - In high voltage areas, CorGrate s non-conductive FRP materials provide protection against electrical shocks. FRP materials are ideal as guards against contact with exposed conductive elements such as railroad third rails. In addition, FRP materials are used as electrical work platforms for non-conductive walkways and as guards around electrical transformers, bus bars, and machinery. Applications for FRP Materials CorGrate fiberglass products have delivered important value to a broad range of industries including: Chemical Refining Metal Treatment Mining Electronics Recreation Pulp and Paper Marine and Offshore Architectural Food and Beverage Water and Wastewater Treatment and others... Typical Uses for CorGrate Grating While new applications for fiberglass products are developed everyday, typical uses include: Walkways Catwalks Screening Flooring Ramps Stairways Stairs Trench Covers Mezzanines Platforms Assembly Lines and more CorGrate Fiberglass Systems 3

4 Selecting Fiberglass Grating Choose from a wide range of standard CorGrate styles. Molded versus Pultruded Grating Molded - With a high resin to glass ratio, (approximately 65% resin to 35% glass by weight) CorGrate molded grating is engineered to provide maximum corrosion resistance in tough conditions such as those found in pulp mills, chemical plants, plating operations and others. The interwoven square mesh construction for CorGrate molded grating results in bi-directional strength. This design, in many cases, eliminates the need for extra structural supports at penetrations that are required for rectangular mesh construction. This can be particularly important in complex process areas that have a large number of openings and penetrations. Pultruded - Covering a wide range of conditions, CorGrate has the broadest line of pultruded gratings available today. Standard sizes are maintained in stock and can be fabricated to length by CorGrate to meet specific needs. The higher glass to resin ratio (approximately 35% resin to 65% glass by weight) of pultruded grating results in sections with higher structural properties than molded sections of similar depth and weight. Because of longer span capability, support structures can be reduced, resulting in lower total cost when using pultruded grating instead of molded. To significantly reduce scrap and thereby lower cost, pultruded gratings can be manufactured in custom length and widths for large projects. The corrosion resistance of pultruded grating is superior to galvanized steel, aluminum, or stainless steel. It is the ideal choice for applications with high load demands or long spans and moderate chemical exposure.

5 Determine resin system based on product environment. Resin Systems and Corrosion Protection CorGrate fiberglass gratings are furnished in three, fire retardant resin systems, each providing a different level of corrosion protection. CorGrate grating furnished in any standard resin system has a low flame spread rating of 25 or less when tested in accordance with ASTM E-84. Specific details and user recommendations for the resin system can be found in the chemical resistance guide on page 21. Vinyl Ester (VF) is a vinyl ester resin system that provides the highest level of corrosion protection and demonstrates better retention of structural properties at elevated temperatures. Isophthalic Polyester (PF) is a premium grade polyester resin designed for applications where there is moderate exposure (splash and spill) to corrosive elements in moderate temperature conditions. General Purpose Polyester (GF) is an economy polyester that meets the corrosion resistance found in light industrial and water/wastewater applications. Both polyester resin systems are acceptable for use in food grade applications, per the United States Department of Agriculture. Receive benefits of using CorGrate s FRP materials. Slip Resistance For molded grating the concave (meniscus) shaped top surface provides very good and durable slip resistance or CorGrate s silica grit surfaces enhance slip resistant surfaces particularly in oily environments. For conditions with unusually high abrasion, CorGrate can furnish an aluminum oxide gritted surface (upon special request) for greater durability. A gritted top surface is standard for pultruded CorGrate sections at no additional charge, and optional for molded gratings for an additional charge. The slip resistant benefit of fiberglass grating offers excellent protection against slips and falls when compared to traditional metal grating. Low Maintenance Fiberglass gratings require virtually no maintenance. Periodic cleaning with water or water containing a mild detergent is recommended to remove build-up or debris and/or foreign material. Avoid using high pressure and/or high temperature water, which could possibly remove and degrade the grit surface. Gratings which are fastened to supports with clips should be periodically checked and the loose clips tightened CorGrate Fiberglass Systems 5

6 Molded SM Series CorGrate Molded SM (Square Mesh) with its high resin to glass ratio provides the maximum corrosion protection of any CorGrate s gratings. Unique to molded section, the bars are the same construction, depth, and spacing in both directions which results in equal strength in either direction. The top surface is skid resistant, meniscus (concave) surface, with an optional quartz or aluminum oxide grit. 1, 1-1/2 or 2 1-1/2 or 2 CC 1-1/2 or 2 CC Standard color for general purpose (GF) is dark gray or yellow.
