1 U.S. COAST GUARD APPROVED to ASTM F EXCLUSIVELY PHENOLIC FIRE INTEGRITY COMPOSITE GRATING

2 FIRE INTEGRITY COMPOSITE GRATING DURAGRID Phenolic Grating continues to set the world offshore standard for Fire Integrity composite grating. Strongwell s use of the highest quality raw materials, state-of-the-art manufacturing processes and superior engineering have produced a product of unmatched quality and performance. The fourth generation of DURAGRID Phenolic exhibits improved mechanical properties, fire integrity, and impact resistance for greater durability. Strongwell s pultrusion facilities are ISO-9001 certified to further ensure that DURAGRID Phenolic is manufactured following the highest quality standards. DURAGRID Phenolic was the first commercially successful phenolic grating and has been exclusively produced in the USA since Features DURAGRID Phenolic Grating has been used to reduce weight and maintenance on offshore oil production platforms since DURAGRID Phenolic Grating is a dramatic innovation for markets where fire safety is a major concern; offering superior corrosion resistance, resistance to high temperatures, low smoke and low toxic fume emissions1. The nonflammable nature of phenolics enable this grating to withstand higher temperatures than traditional FRP products for extended periods of time. Combined with very low thermal conductivity, DURAGRID Phenolic Grating offers the best strength-to-weight ratio for projects that require maximum weight optimization with fire protection not available from alternative materials. DURAGRID Phenolic Grating is the first composite grating to receive U.S. Coast Guard approval. It is accepted for use in locations and applications as allowed in the ASTM F3059 Matrix guide for fiberglass grating meeting Structural Fire Integrity Level 2 (L2). The ASTM F3059 enhances and will replace the USCG PFM 2-98 matrix. In addition, DURAGRID Phenolic Grating has these features: Strength of Steel Compared to new standard steel grating, DURAGRID DURAGRID Phenolic Grating s unique construction allows for many penetrations to be cut without adding additional supports. Phenolic I mm (1-½") can carry 2.53 times the load of equivalent steel grating. Unlike metal gratings, DURAGRID Phenolic has memory, returning to its original shape if design loads are exceeded. Ease of Fabrication DURAGRID Phenolic Grating requires no hot-work or heavy equipment to install or make field modifications. The unique three piece cross-bar construction enables DURAGRID to be cut like a solid sheet with simple hand tools no need for banding as with metal grating. Lightweight, Easy to Install DURAGRID Phenolic is approximately one- third the weight of steel bar grating. It is also much lighter than molded FRP grating, yet many times the strength. Above: DURAGRID Phenolic Grating s 3-piece cross-rod system has been time tested for durability. Left: DURAGRID Phenolic Grating is very lightweight. The initial installation or removal of panels for area access can be performed quickly. Dependable Non-Skid Surface For Safety and Comfort DURAGRID Phenolic Grating has a non-skid surface for superior slip and impact resistance. The product complies with the rigorous requirements for nonskid capability and demanding durability within ASTM F3059. The wide bearing bar is less fatiguing and friendlier to work on than serrated steel grating and is not dangerously sharp like some molded gratings. High Impact and Fire Resistance DURAGRID Phenolic s proprietary (exclusive) construction exceeds the impact requirements (dropped object and high trolley loading) of ASTM F3059. The improved durability provides the highest return on investment when it comes to the product s life cycle costs while meeting the higher fire requirements of the same ASTM requirement. 1 Toxicity levels comply with IMO Typical Applications Offshore production platforms Aircraft FLNG/LNG vessels Mobile offshore drilling units Docks/jetties/load-out areas Extreme cold (Arctic) areas Shipboard applications (MODU s) Mining 2 Industrial/processing plants Tunnels/mass transit Refineries

12 How to Specify DURAGRID Phenolic Fiberglass grating shall be DURAGRID Phenolic Series ( ) as manufactured by Strongwell. Grating shall be pultruded using phenolic resin and assembled in the U.S.A. The grating shall have a current Level 2 USCG Type Approval to ASTM F and meet the smoke and toxicity requirements of Annex 1 (resolution MSC.307 (88)), Part 2, 2.41 and 2.42 of the FTP Code as issued by the International Maritime Organization (IMO). 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-rods shall be spaced a maximum of 6" in the panel. The top of the panels (shall) (shall not) be covered with a bonded grit anti-skid surface. Color shall be earthenware brown (RAL 8023) signifying Fire Integrity. NOTE: If special options are required that are not stated in the above specification, fill in your special requirement in the appropriate section. 1 ASTM F3059 includes requirements for structural fire integrity, durability, (impact and wheel loads) and ASTM tests: B117, D2047, D4060, D4329, E84, E119, E695. How to Order When ordering DURAGRID Phenolic, 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 crossrods. Length is always the bearing bar length.
