Fiberglass Reinforced Plastic (FRP) grating is increasingly specified for data centers, industrial facilities, manufacturing plants, and utility infrastructure where safe, slip-resistant access to equipment and service areas is essential.
Combining corrosion resistance, a high strength-to-weight ratio, and an integral slip-resistant surface, Archatrak SpanTrak FRP grating provides durable, low-maintenance walking surfaces for maintenance walkways, equipment access routes, platforms, catwalks, trench and drain covers, and other industrial service areas. Lightweight 4′ × 8′ panels can be easily cut and fabricated on site with standard tools, allowing installations to adapt to changing equipment layouts without welding or specialized fabrication.
Archatrak SpanTrak FRP grating panels are manufactured with Type I Isophthalic resins and Aluminum Hydroxide filler, achieving a Class A fire resistance rating when tested to ASTM E84. Supplied with an integral gritted slip-resistant surface, SpanTrak delivers long-term durability with minimal maintenance, making it a reliable solution for critical infrastructure where worker safety, dependable performance, and reduced lifecycle costs are priorities.
Benefits of SpanTrak FRP Grating for Data centers and industrial applications

Spantrak Grating Options
SpanTrak panels are supplied as standard in 4′ x 8′ sheets with a gritted anti-slip surface finish in dark grey. For beachfront boardwalks where barefoot traffic is common, a smoother meniscus finish is available as an alternative to the standard grit.
SpanTrak MacroMesh is our widest aperture fiberglass grating, designed for applications where maximum drainage, airflow, and debris passage are important. With a 1-1/4″ × 1-1/4″ mesh opening MacroMesh provides secure footing while minimizing material weight at just 3.0 lb./sq.ft. Panels are manufactured in 1-1/4″ thickness with 1-1/2″ deep load bars spaced 1-1/2″ on center, making them suitable for joist spacing up to 24″ on center.
SpanTrak MidiMesh is an excellent all-around choice for industrial settings. With a 1/2″ x 1/2″ aperture size, MidiMesh provides excellent foot coverage, accommodates high heel traffic, and delivers a smooth rolling surface for wheelchairs, bicycles, and carts. Panels are supplied in 1-1/4″ thickness for joist spacing up to 24″ on center.
SpanTrak MiniMesh offers a tighter 1/4″ x 1/4″ aperture for applications where an exceptionally smooth rolling surface is the priority. A good option for high-traffic accessible pathways or where scooters and wheeled equipment are in regular use. Available on special order.
Custom panel sizes and colors are available on special order for either option.
Specifications
For boardwalk decking applications, Archatrak only supplies gratings manufactured with pure isophthalic resins and not lower cost polyester resins which do not offer sufficient long-term durability in harsh exterior conditions.
All our fiberglass grate panels use aluminum hydroxide filler (not calcium carbonate) for maximum fire resistance (flame retardant and smoke suppression) and contain UV stabilizers.

Installation
Archatrak porcelain cobblestone pavers used as driveway pavers should be laid Archatrak SpanTrak fiberglass grate panels for boardwalk decking applications are normally fixed to support bearers with max. span of 48″ (depending on the thickness of the fiberglass panel and anticipated loadings) using stainless steel M clips inserted in the grating apertures, with a minimum of four clips per panel. L clips are generally not recommended as they don’t have the same strength as M clips.
Where necessary, adjacent panels can be joined at the edges by means of stainless steel C clips.
Since the aperture size of MicroMesh panels is only 1/4″ x 1/4″, these panels are typically fixed to bearers with stainless steel screws or bolts with a 1/2″ diam. (min) head and a 6-lobe (Torx or equiv.) drive. A diamond cone drill with no pilot drill can be used to countersink the screws so the screw heads sit flush with the surface of the panels.
Where panels are installed over steel I or H beams and it may be difficult to drill through the beams, hold down clips with an extended base plate may be used.
Where a change in direction is required on a boardwalk, panels can be cut at an angle, taking care to ensure adjacent panels are cut at the same angle so the load bars match up when panels are joined.

FAQs
Frequently Asked Questions About FRP Grating for Data Centers and Industrial Applications
Customer SupportYes. FRP grating is widely used throughout data centers for cooling tower platforms, equipment access walkways, service platforms, utility trench covers, and other maintenance access areas. Its corrosion resistance, lightweight construction, slip-resistant surface, and electrically non-conductive properties make it well suited for demanding mechanical and utility environments.
Unlike painted or bonded anti-slip coatings that can wear over time, SpanTrak FRP grating can be manufactured with an integral gritted surface that becomes part of the panel during production. This provides long-lasting slip resistance for maintenance walkways, platforms, and industrial access areas without requiring periodic recoating or replacement of the walking surface.
Yes. SpanTrak FRP grating panels are engineered to support pedestrian traffic and maintenance loads for elevated walkways, service platforms, trench covers, and industrial access systems. Multiple panel thicknesses and mesh configurations are available to meet the structural requirements of different applications.
Unlike steel grating, FRP will not rust or corrode in wet or chemically aggressive environments and requires no painting or protective coatings. It is significantly lighter than steel, electrically non-conductive, easy to fabricate on site, and provides excellent slip resistance, helping reduce installation time and long-term maintenance requirements.
Yes. SpanTrak FRP grating can be installed on adjustable pedestal supports or low-profile rubber support pads to create level maintenance walkways over piping, conduit, ductwork, and other rooftop utilities. This approach maintains airflow, drainage, and access to the systems below while providing a safe, durable walking surface.
