DURAGRID® Phenolic Grating: Elevating Safety and Performance in the Oil and Gas Industry

When it comes to ensuring excellent fire and smoke performance, DURAGRID® Phenolic Grating stands as the go-to choice in the oil and gas industry. As the first composite grating to receive U.S. Coast Guard approval, DURAGRID® Phenolic meets the stringent requirements of the ASTM F3059 Matrix guide for fiberglass grating, achieving Structural Fire Integrity Level 2 (L2). In fact, the ASTM F3059 will soon replace the USCG PFM 2-98 matrix, solidifying DURAGRID® Phenolic Grating’s position as a leader in safety.

 

Unmatched Fire and Smoke Performance

In comparison to standard polyester, vinyl ester, and epoxy FRP products, Phenolic Grating offers significant improvements in reduced smoke density, reduced smoke toxicity, and enhanced structural fire integrity when exposed to fire incidents. Meeting Annex 1 of the FTP Code (International Code for Application of Fire Test Procedures) – (MSC 88/26/ Add.2) issued by the International Maritime Organization, DURAGRID® Phenolic Grating ensures safety and compliance with rigorous fire safety standards.

The 3-Piece Cross-Rod System: Superior Stability

Setting a new industry standard, Strongwell’s 3-piece cross-rod system outperforms competitive crossrod systems with its unparalleled stability. Combining three-piece members and Strongwell’s proprietary bonding method, this system tightly ties the bearing bars together, enhancing the overall stability of the grating panel. As a result, DURAGRID® Pultruded Grating stands as the top choice for industries seeking optimal safety.

 

Custom Grid and Grating Systems: Tailored to Your Needs

Understanding that not all applications can be met by standard fiberglass grating, DURAGRID® offers custom grid and grating systems to accommodate specific requirements. The customer gains complete flexibility with options like bar spacing selection, custom bar shape, cross-rod placement, resin or color customization, and even custom fabrication. The result is a personalized solution that perfectly fits your unique needs.

 

Effortless Fabrication and Installation

DURAGRID® gratings’ lightweight composition ensures easy handling during installation, making it a cost-effective alternative to steel grating. The patented 3-piece cross-rod system locks and bonds the cross-rods to the web of each bearing bar, affixing them firmly in position and distributing concentrated loads to adjacent bars. This system allows DURAGRID® grating to be cut and fabricated like a solid sheet, with standard carpenter’s tools with abrasive cutting edges serving the purpose. Simply coat the cut ends with resin sealer, and you’re ready for a seamless installation.

 

Attachment Methods: Optimal Fasteners for Enhanced Decking

For all Strongwell decking products, including DURAGRID® Phenolic Grating, the preferred fasteners are available, ensuring a secure and reliable attachment method. With various fastener options and illustrated uses provided in the Decking Fasteners flyer, you can make informed decisions and ensure an optimal decking solution.
