A leading packaging manufacturer required a safe and durable GRP grating walkway to improve access between production areas within a high-traffic facility. The previous steel flooring had deteriorated due to chemical exposure and constant washdown cycles, creating safety concerns and costly downtime.
A custom-designed open mesh GRP grating system was installed to create a lightweight, corrosion-resistant bridge between production zones. The integrated quartz-gritted surface provided a certified anti-slip finish, ensuring secure footing for operators even in wet conditions.
The prefabricated panels were rapidly installed without interrupting ongoing operations, offering a load capacity of up to 5 kN/m² and long-term resistance to moisture, cleaning agents, and wear. The result was a safer, low-maintenance access route that eliminated rusting, improved workflow efficiency, and reduced future maintenance costs.
This project demonstrates how GRP grating walkways can transform safety and productivity in industrial environments requiring continuous operation and reliable surface performance.
The main advantage of GRP grating over steel or aluminium flooring is longevity and maintenance. GRP gratings are made from glass reinforced plastic, which means they do not rust, corrode, or conduct electricity. Steel and aluminium require regular coating and inspection to prevent surface wear, while GRP performs reliably for decades without treatment.
The lightweight nature of fibreglass grating makes handling, cutting, and installation simple, reducing both labour and equipment costs. It is also non-sparking, non-magnetic, and resistant to chemical attack, which is ideal for industrial and marine environments. Despite its light weight, GRP grating has an impressive strength-to-weight ratio, typically supporting loads of up to 7.5 kN per square metre depending on thickness and spacing.
The quartz-gritted surface provides permanent slip resistance even when wet or oily, giving it a safety advantage that traditional metal flooring cannot match. In every aspect of durability, cost, and safety, GRP gratings deliver more value over time than conventional materials.
GRP gratings are specifically designed to offer exceptional traction under all conditions. Each GRP grating panel features a bonded quartz-gritted surface that maintains grip in wet, oily, or high-traffic areas. Slip resistance is independently tested to BS 7976-2 Pendulum Test Values, confirming excellent performance for industrial and public environments.
Open mesh GRP grating allows water to drain quickly, reducing surface pooling, while mini mesh variants provide a smoother underfoot feel for pedestrian zones. Because the grit is integrated during manufacture, it does not peel or lose effectiveness over time. This means the slip protection remains consistent for the life of the product. Fibreglass grating is also unaffected by corrosion or contamination, so cleaning is simple and performance is easily maintained.
Whether used on access platforms, stairways, or walkways, GRP gratings retain their grip and keep operators safe even in the harshest conditions, outperforming metal flooring and timber decking in both traction and long-term reliability.
Fire performance is a critical part of GRP grating design. All GRP gratings are manufactured using flame retardant resins and are tested to achieve Class 2 fire rating under BS 476 Part 7 and ASTM E84 Class 2. This certification ensures a controlled flame spread and reduced smoke generation during a fire event.
The material is also non-conductive, which makes it ideal for environments where electrical safety is essential. GRP grating can operate effectively in temperatures ranging from minus forty degrees Celsius to plus one hundred and twenty degrees Celsius without structural deformation or loss of strength. Vinyl ester resin systems provide enhanced heat and chemical resistance, making them suitable for enclosed industrial areas or chemical processing plants.
The combination of non-conductive properties and stable thermal behaviour gives GRP gratings a unique advantage over metal flooring, providing both safety and peace of mind in high-risk locations where performance cannot be compromised.
GRP gratings are highly resistant to corrosion and chemical attack, making them a preferred choice for marine, industrial, and wastewater applications. The glass reinforced plastic structure is produced with isophthalic or vinyl ester resin, both of which provide outstanding protection against acids, alkalis, and solvents.
This composition prevents rust, rot, and surface pitting even when exposed to saltwater or aggressive cleaning agents. The non-metallic nature of GRP grating also means it does not react with surrounding materials or create galvanic corrosion issues. In demanding environments such as chemical plants, offshore platforms, or treatment facilities, GRP gratings maintain full mechanical integrity for decades with minimal maintenance.
The smooth resin finish makes cleaning simple and prevents buildup of contaminants, further extending service life. For any location exposed to moisture or corrosive substances, GRP grating provides a cost-effective, long-term alternative to coated steel, delivering exceptional strength, safety, and resistance throughout its working life.
GRP grating combines lightweight design with impressive load-bearing performance. Depending on configuration and span, panels can support loads of five to seven and a half kilonewtons per square metre, making them ideal for platforms, walkways, and maintenance flooring. The strength comes from continuous glass fibre reinforcement that distributes loads evenly and minimises deflection.
Solid top and pultruded GRP gratings provide additional stiffness for heavy-duty industrial applications, while open mesh designs allow drainage and ventilation without compromising strength. Despite being up to seventy-five percent lighter than steel, fibreglass grating can outperform metal in both impact resistance and dimensional stability. It is also quieter underfoot and easier to cut or shape on site.
This combination of strength, light weight, and flexibility gives engineers a reliable, maintenance-free flooring option that can withstand demanding industrial conditions while remaining easy to handle, install, and maintain for the long term.
Yes, GRP grating is simple to adapt during installation. Panels can be cut, trimmed, or drilled using standard tools fitted with tungsten carbide blades. Unlike metal flooring, no welding, coating, or hot work is required. Sections can be shaped precisely to fit around equipment, drains, or irregular spaces without affecting structural strength.
Fixings such as stainless steel saddle clips and M-clamps secure the grating firmly to its supports while allowing quick removal if needed. GRP gratings are also available in a wide range of sizes, colours, and surface finishes, including open mesh, mini mesh, and solid top configurations.
This adaptability means each project can be tailored exactly to its functional and visual requirements. Whether used for walkways, riser floors, or access platforms, fibreglass grating offers the flexibility and practicality needed to deliver professional results in any industrial, marine, or commercial installation.
Outdoor performance is one of the greatest strengths of GRP gratings. The resin system includes ultraviolet stabilisers that protect against colour fading, weathering, and surface degradation from sunlight. Unlike painted steel, the pigment is integrated throughout the composite, ensuring that the colour remains stable even after many years of exposure.
GRP grating is fully resistant to rain, frost, and temperature changes, maintaining its strength and slip resistance in all seasons. In coastal or rooftop applications, it resists salt spray and moisture without corrosion or delamination. The surface remains easy to clean, and the anti-slip grit continues to perform underfoot.
This combination of UV protection, chemical resistance, and structural integrity makes GRP gratings ideal for long-term use outdoors, from bridges and marinas to utility platforms and rooftop access routes, delivering dependable performance year after year with almost zero maintenance.
GRP gratings offer both function and design flexibility. Standard colours include industrial grey, green, and high-visibility yellow, which are chosen for durability and compliance with safety standards. Custom RAL colours can be produced on request to match architectural schemes or company branding.
The pigment is fully blended into the resin, meaning the colour will not chip, flake, or require repainting. Several finishes are available to suit the application, including open mesh for drainage, mini mesh for pedestrian comfort, and solid top for spill containment. Each version features a gritted surface that provides long-term slip resistance.
This level of choice allows specifiers to combine visual appeal with performance, creating flooring and walkways that are not only strong and safe but also complement their surroundings. Whatever the environment, there is a GRP grating finish and colour combination to meet the exact requirements of the project.
GRP gratings are designed for a service life of at least twenty-five to thirty years, depending on usage and exposure. Maintenance requirements are minimal. The material does not corrode, rot, or degrade, even in harsh marine or chemical conditions. Regular cleaning with water or a mild detergent keeps the gritted surface clear of dirt and debris, ensuring continued slip resistance.
There is no need for painting, sealing, or recoating. The colour remains stable because it is part of the composite, not an external finish. Any necessary modifications can be made on site using hand tools. Because GRP grating resists impact, moisture, and temperature change, its long-term cost of ownership is significantly lower than steel or timber alternatives. Once installed, it simply continues to perform, providing safe, reliable, and attractive flooring for decades without interruption to operations.
The cost benefits of GRP gratings become clear when considering their full lifecycle. Initial purchase prices can be similar to steel, but the savings in installation, maintenance, and replacement make GRP far more economical over time. Because it is lightweight, fewer lifting tools are required, and labour time is reduced. GRP does not rust or require protective coatings, so maintenance budgets shrink dramatically. Its long service life means fewer replacements and less downtime, both of which contribute to long-term savings.
In environments exposed to chemicals, salt, or constant moisture, these advantages multiply. The non-conductive, slip-resistant, and fire-rated design also reduces accident risk and insurance costs. When evaluated over twenty years or more, GRP gratings typically deliver a lower total cost of ownership than galvanised steel, making them a smart, sustainable, and dependable investment for any industrial or commercial flooring project
