GRP container

If you need to ship or store unusually shaped or large items – such as aerospace components, military or medical equipment or other specialist parts and products – GRP containers are a great option.

Manufactured using glass-reinforced plastic, GRP containers can be made in any size up to 8 metres in length without minimum order quantities or tooling costs. GRP cases offer durability, water resistance and overall strength and performance comparable with roto moulded cases. They have an operational lifespan in excess of 20 years. They also allow for a wide range of custom options besides their size, including colours, handles, lifting gear, security features, etc. Read more

About GRP containers

GRP containers provide an excellent strength-to-weight ratio and are extremely tough and durable. However, arguably their most significant advantage when compared with other rugged cases – such as roto mould – is their size flexibility.

You can specify a custom-sized GRP case with no tooling charge and no minimum order quantities. Bespoke sizing can help improve the protection provided to your products or components during transit and make transportation more efficient (as you are not paying to ship empty space within the case).

GRP containers are also ideal for very large or unusually shaped items, with the possibility of manufacturing cases up to 8 metres in length.

Besides the benefits of bespoke sizing, GRP cases are also hermetically sealed to prevent moisture and dust ingress and remain stable in extreme climates/temperatures. These properties, coupled with their inherent durability, mean GRP containers typically have an operational lifespan in excess of 20 years.

Other optional features include fire retardant properties, adding a range of handles, lifting eyes, silica ports (to prevent condensation within the case) and even a choice of colours. These features are in addition to the wide range of internal fittings available through GWP.

All this adds up to make GRP containers particularly suited to military, aerospace and heavy-duty industrial parts and applications.

Key benefits of GRP containers

The key benefits of GRP cases include:

  • Extremely tough and durable to protect items during transit.
  • Excellent strength-to-weight ratio.
  • Exceptional reusability, with an operational lifespan in excess of 20 years.
  • Resilience and stability in extreme climatic conditions.
  • Hermetically sealed to prevent water and dust ingress.
  • Custom sizes (and colours) improve protection and transport efficiency.
  • Particularly suited to large or unusually shaped items (up to 8 metres long).
  • Available with no MOQs (from single units) and no tooling charges.
  • Can be supplied with fire retardant properties.
  • Range of options including handles, catches, lifting eyes/hooks, silica ports, etc.

What does GRP stand for?

GRP stands for glass-reinforced plastic. GRP is a composite material commonly used in boatbuilding, automotive body components and street furniture, but it is also suitable for manufacturing heavy-duty, rugged cases.

How are GRP containers made?

GRP, consisting of glass fibre matting and thermoplastic resin, can be moulded or formed into shape. Moulded cases require tooling. Alternatively, the fibreglass can be ‘laid up’ over a substrate to form a laminate with a different material (such as a heavy-duty corrugated). This option requires no tooling. However, either process creates an extremely strong and rigid structure with an excellent strength-to-weight ratio.

Are GRP containers as tough as roto moulded cases?

GRP containers offer protection, strength and general performance comparable to rotationally moulded cases. However, their main benefit is that it is possible to specify custom sizes, which can help improve protection in transit further.

How long do GRP containers last?

GRP containers typically have an operational lifespan in excess of 20 years. Whilst this can vary depending on the conditions they encounter, it makes them ideal for the long-term storage of parts and equipment.

What size GRP cases are there?

GWP can manufacture GRP cases at the specific size that you require. The smallest case is approximately 1 meter cubed, with the largest being approximately 8 metres long.

Custom pricing for custom cases

One of the crucial benefits of GRP containers is that you can specify the exact size you require. Whilst this means improved performance, this, along with the range of additional options you can choose, makes it impossible to list prices on this site.
