GRP Cable Support Solutions
Did you know that there is an alternative option to steel cable support solutions, which is more durable and has less hassle while handling? Through this article, we will explore the features of GRP, its additional and unique benefits in cable support applications and discover the Mita brand.
Thorne & Derrick are an approved distributor of the MITA brand, now powered by Wibe Group, providing competitive prices and fast delivery from stock for the complete range of cable troughs, CABSYS cable trays & GRP cable ladders
What is GRP?
GRP or FRP is the abbreviation for Glass/Fibre Reinforced Polymer, meaning it is a man-made resin based material which makes it a polymer, reinforced with glass. Polymer itself is extremely strong – it is a fibre material and in contrary to how it sounds, it is very durable. It is resistant to most chemicals, stretching and shrinking, resistant to mildew and abrasion as well. When it is reinforced with glass through pultrusion, it becomes a structural polymer resistant to fire and highly corrosive environments. Furthermore, it does not conduct heat. GRP has extra durability to adverse weather conditions and has UV stability which makes it an excellent candidate for outdoor applications, even for wind power substations built in the middle of the sea.
GRP cable support
Cable support is the backbone of any development. Wherever there is a structural development, cable support is there to facilitate electrification, signalling and data.
GRP cable support systems possess unique properties which provide structural strength as much as a stainless steel installation and resist many corrosive environments, particularly where conditions indicate that conventional materials may not provide an economic service life.

Features of GRP Cable Support Solutions vs Steel
Supporting Applications With A long Standing Brand
Mita GRP, designed and manufactured in the UK, is now powered by Wibe Group. Thorne & Derrick supply and distribute the complete GRP cable support system range specifically designed for harsh and corrosive environments, ensuring a sustainable installation through its lifetime. Serving industries of transportation, onshore and offshore power, water and waste management, chemicals, pharmaceuticals and many more, Mita GRP stands for “peace of mind” with its “fit and forget” solutions for generations to come.
Working with GRP
Another particularly useful feature of Mita GRP cable support solutions and systems is its ability to be integrated with the Bentley Raceway and Cable Management Building Information Modelling (BIM) tool. This provides a complete layout, routing and material estimating function in a single, integrated system. It can be applied from the initial concept design through to detailed design and construction. A user can create an accurate 3D model of the cable troughing route, making it easy to ensure that adequate space and clearances are available in confined locations, and for the detailed design and material requirements to be quickly and easily produced.
In conclusion, the Mita GRP cable trough system is a non-hazardous, inert product. It is lightweight and can be manually handled without difficulty, unlike concrete and steel. In contrast to steel, GRP does not have to be deburred or given edge treatment before fitting, saving time and further reducing labour costs. During installation, any cutting, drilling, bonding and jointing can be easily undertaken and will not give rise to a hazardous situation, with any dust kept to a minimum.
