Moulded vs. Pultruded, plus a description of various FRP finishes.
Staircare SC-R Fiberglass Reinforced Polymer FRP products come in 2 structures (Moulded and Pultruded) to suit a range of applications. Once the appropriate FRP structure is chosen, the product can then be constructed with your selected finish. For any assistance, please contact us.
FRP Structure Options
Staircare SC-R Moulded FRP Grates
Staircare SC-R Moulded FRP GratesMoulded FRP Grates are available in either square mesh or rectangle mesh configuration. They are formed using continuous interwoven glass fibers encapsulated with a resin matrix. Moulded square mesh grates offer bi-directional strength and are ideal for installations requiring multiple penetrations.
Staircare SC-R Pultruded FRP Grates
Staircare SC-R Pultruded FRP GratesPultruded FRP grates offer only one directional load bearing properties, they have exceptional strength and are able to provide much greater load spans than the equivalent height moulded grating. Pultruded grates are made of ‘I’ or ‘T’ type pultruded independent load bars. Pultruded grates are widely used for platforms where large spans are required.
FRP Finishes
 |
Smooth Surface FRP Grating FPR grating with smooth surface finish is suited for waste water solids screens, fences, machine screens etc. Smooth surface grating can also be produced in translucent form for decorative application. |
 |
Concave Surface FRP Grating FRP grating with a concave surface, finish is suited for light foot traffic, food preparation and other hygiene applications, or in areas where non conductive and non sparking properties are important. |
 |
Gritted Surface FRP Grating During the manufacturing process a silicon carbide anti-slip grit is incorporated into the surface to offer a high resistance anti-slip surface. |
 |
Mini Mesh FRP Grating Mini Mesh has a 12mm x 12mm open mesh area. The smaller mesh opening prevents objects from falling through. Suitable for pedestrian walkways, boardwalks, safe access for disabled, and wheelchairs. |
 |
Gritted Cover Plate Grating An approx 3mm thick plate is bonded to the grate to form a strong, lightweight covered panel. Panels are available with silicon carbide grit and offer light but strong trench covers, walkways cable throughs and pit covers. |
FRP Resin System Choices
Three standard resin systems are available to handle almost any application. For any assistance, please contact us.
