FRP Grating Styles & Sizes
Archatrak exclusively supplies FRP grating for exterior deck surfaces – boardwalks, walkways, marinas, and rooftop support for planter trays, synthetic turf and porcelain pavers. We supply grating in a standard size of 8′ x 4′ for optimum transportation, handling and installation considerations and in three mesh sizes which satisfies all but the most specific of decking applications. For such exceptional applications, we can usually supply other grating sizes, styles, resin composition and surface finish on request, subject to minimum order size.
MacroMesh
Our MacroMesh grating has 1 ½” x 1 ½” primary load bars giving an aperture size of 1 ¼” x 1 ¼”.
MacroMesh gratings are typically used where there are no concerns about small objects falling through the mesh and the panels will not be subject to small wheeled traffic. Normally MacroMesh grates are supplied with the factory default concave surface finish on the top of the load bars but a gritted finish can be supplied where extra slip resistance is required.
MacroMesh grates are commonly used for roof access walkways, industrial platforms and marinas.
| Primary grid bars | 1 ½” x 1 ½” (on center) |
| Aperture | 1 ¼” x 1 ¼” |
| Load bar thickness | ¼” |
| Open space | 68% |
| Std. panel thickness | 1” |
| Panel size | 4′ x 8′ |
| Weight | 2.5 lb/sq.ft. |
| Color (std.) | dark grey (other colors on request) |
MidiMesh
Our MidiMesh grating has 1 ½” x 1 ½” primary load bars with an extra intermediate cross bar at the top of the grating, ½” deep creating a ½” x ½” aperture. The smaller apertures provide good water drainage and airflow, prevent objects from falling through and provide a surface more suitable for small children, pets, prams, cyclists, wheelchairs, and other small wheeled traffic.
MidiMesh grating panels are typically preferred for elevated public walkways, especially in parks and reserves, as well as pedestrian access decking on docks, piers, boat lifts, pontoons and jetties. The panels are also useful around pools, waterparks and other general recreational areas.
MidiMesh is typically supplied with a bonded grit surface to prevent slippage during wet or icy conditions, thus allowing all year usage of pedestrian walkways and other elevated access paths. However for beach access applications, grit surfaced FRP can be harsh on bare feet. For greater comfort, MidiMesh with a meniscus surface could be considered which still provides good degree of ant-slip properties.
| Primary grid bars | 1 ½ x 1 ½” (on center) |
| Secondary grid bars | ¾” x ¾” (on center) |
| Aperture | ½” x ½” |
| Load bar thickness | ¼” (primary), ¼” (secondary) |
| Open space | 42% |
| Std. panel thickness | 1 ¼” |
| Panel size | 4′ x 8′ |
| Weight | 3.5 lb/sq.ft |
| Color (std.) | dark grey (other colors on request) |
MiniMesh
Our MiniMesh grating has 1 ½” x 1 ½” primary load bars with two extra intermediate crossbars at the top of the grating, ½” deep, creating apertures of just ¼” x ¼”. The small apertures prevent most objects from falling through but still offers good drainage.
MiniMesh is recommended for ‘pedestrian-friendly’ walkways frequented by pet walkers, strollers, carts, other small wheeled vehicles and especially high heel shoe wearers. For elevated turf applications, the small aperture size creates a smooth, strong surface that still allows water to drain efficiently.
MiniMesh decking is typically used on docks, piers, boat lifts, pontoons, jetties and decks. It is also used in and around pools, marinas, waterparks and other public recreational areas.
| Primary grid bars | 1 ½” x 1 ½” (on center) |
| Secondary grid bars | ½” x ½” (on center) |
| Aperture | ¼” x ¼” |
| Load bar thickness | ¼” (primary), 3/16” (secondary) |
| Open space | 30% |
| Panel thickness | 1 ¼” only |
| Panel size | 4′ x 8′ |
| Weight | 4.5 lb/sq.ft. |
| Color (std.) | dark grey (other colors on request) |
Panel dimensions may vary by up to 1/8″. Allowances should be made for this manufacturing tolerance when constructing frames to contain panels.
