GRP Grating Panels For Flooring, Walkways & Covers

GRP grating panels are versatile, resilient, and ideal for a wide array of applications, including flooring solutions, walkways, and covers. These panels are engineered from high-strength Glass Reinforced Plastic, making them a robust and durable choice for both indoor and outdoor settings. 

The benefits of GRP grating panels are multifaceted, encompassing high corrosion resistance, lightweight design for easy installation, and minimal maintenance requirements, ensuring long-term cost-efficiency.

Applications of GRP grating panels are diverse, ranging from industrial flooring, walkways in corrosive environments, to covers for drainage systems and trenches. Their adaptability is further enhanced by the availability of different types:

Open mesh gratings are ideal for environments requiring robust and reliable flooring with excellent drainage capabilities. Their open design ensures easy passage of light, air, and liquids, making them a popular choice in industries where ventilation and unhindered water flow are crucial. These gratings are known for their slip-resistant properties and high load-bearing capacity, making them suitable for heavy-duty applications.

Open mesh GRP gratings are commonly used in a variety of applications, including but not limited to:

  • Industrial platforms and flooring

Mini mesh gratings provide all the benefits of traditional open mesh gratings but with smaller openings. This design feature makes them particularly suitable for areas where high heels or small wheeled trolleys are used, as it prevents objects from getting trapped or stuck. Mini mesh gratings offer enhanced safety and comfort without sacrificing strength or durability.

These panels offer unique properties and are commonly used in a range of applications including;-

  • Stair treads and landings
  • Pedestrian bridges
  • Water treatment plants
  • Oil and gas installations

Solid top gratings are designed for maximum coverage and safety, providing a uniform, non-slip surface that is ideal for walkways and work areas. These gratings offer the highest level of support and stability, making them suitable for heavy foot traffic and equipment. Their solid construction also makes them a preferred choice in areas where spill containment is necessary, as they effectively prevent liquids from passing through.

Their low maintenance and longevity make them a cost-effective choice for various applications including;-

  • Industrial flooring and walkways
  • Platforms and mezzanines
  • Water treatment facilities
  • Oil and gas installations

GRP (Glass Reinforced Plastic) moulded stair treads are a type of staircase component designed for safety, durability, and ease of installation. These treads are made by combining reinforced plastic with glass fibres.

GRP moulded stair treads are an excellent choice for ensuring the safety and durability of staircases in various settings including;-

  • Pedestrian bridges and walkways
  • Access stairs in public transportation stations
  • Fire escapes
  • Ramps and access points

GRP Moulded Stair Treads

Stair Tread Panel

Available in stock NOW

Stair treads have a different loading pattern to normal grating so Engineered Composites supplies from stock a special type of moulded grating designed for use as a tread or for the step-off point at the edge of a platform or walkway. The grating is a rectangular mesh to give additional strength across the width of the stair tread. It also includes a heavy nosing to carry the edge loading on the tread and to give extra grip. All these beneficial features means the stair treads meet all the requirements of BS4592.

The grating panel is 3660mm x 572mm wide with a nosing section on both long edges. This allows two treads widths to be cut from the panel at lengths to match the stair width.

Our GRP grating systems and GRP grating panels comply with relevant UK and Europe standards. All our GRP grating, anti-slip systems and flooring are fire retardant to ASTM E 84. We also adhere to the BS EN ISO 14122 Permanent Means of Access to Industrial Equipment and BS 4592 Industrial Flooring, Walkways and Stair Treads regulations.

GRP grating and flooring systems can be easily cut to shape, enabling installations to be completed quickly, even for the most complex schematics. Our products can be made to order in other resin systems, including vinyl ester for the ultimate corrosion and fire resistance.

What Are GRP Gratings Used For?

GRP Moulded Gratings are predominantly used for industrial platforms, bridges, and walkways. Although steel gratings are the traditional type of material used in many settings, GRP is fast becoming the superior alternative. GRP Moulded Gratings products supplied from Engineered Composites are effective within a variety of settings.

What Are The Main Features?

There are many outstanding features with Moulded Gratings that makes them the number one choice for industrial settings. They are corrosion-resistant and last beyond ten years without any maintenance required. They are also able to withstand all types of chemicals and weather conditions so they are more than sufficient for aggressive-type environments which may include chemical plants and oil rigs. Furthermore, they are also incredibly robust and sturdy which is another reason why GRP is the best option.

Are They Fire Resistant?

Yes, of course. All GRP Moulded Gratings supplied and delivered by Engineered Composites are fire-resistant to ASTM E 84 and BS476 Class 2.

What Are The Colour Options?

The three main colours that we currently have available are green, green and yellow which suit the majority of commercial and industrial environments perfectly. Panel size and panel thickness vary depending on your preferences and requests.

How long do GRP gratings last?

GRP gratings have a long service life due to their corrosion resistance and durability. They do not rust, rot, or degrade like metal gratings. With proper installation and maintenance, GRP gratings can last for many years, often up to a decade or even longer in some cases, making them a cost-effective and reliable choice for flooring and structural applications. Whether you’re purchasing open mesh grating, or an alternate option, you can expect a long service life!

How do GRP gratings compare to steel gratings?

GRP gratings offer advantages over steel gratings. They are lighter in weight, corrosion-resistant, non-conductive, and require less maintenance. GRP gratings are also more comfortable to walk on, as they do not transfer heat like steel gratings. And of course, they offer a much better environmentally-friendly alternative so you’ll also be doing your bit for a more sustainable future.

Can GRP gratings withstand harsh environments?

Yes, GRP gratings are highly resistant to corrosion caused by chemicals, moisture, and UV radiation. They can withstand harsh environments, including exposure to saltwater, making them suitable for marine or offshore applications. Engineered Composites also regularly supply GRP gratings for industrial use, for example, oil and gas.
