GRP CABLE tROUGH, tRAY & lADDER
MITA brand is now powered by Wibe Group.
MITA have been supporting customers through their technical journey on choosing the correct product, manufactured from GRP, in cable support applications for almost five decades. MITA are now fully separated operationally from Schneider Electric. They now have a stand alone presence in the UK market with their “Made in UK” products which are fully compliant to the related cable management standards.
MITA are marker-leaders in the manufacture of GRP non-metallic cable troughing, ladders, trays (the CABSYS range), ducts, cable support channels and Fibastrut as the brand continues to lead the industry towards a sustainable future for a wide range of low (LV), medium (MV) and high voltage (HV) cable installation applications. The GRP offer includes a complete industrial cable support and cleat systems range specifically designed for harsh and corrosive environments to carry and support electric cable, data, instrumentation, computer or power cables.

mita Features
| Lightweight | Density and weight are significantly lower than steel (70% lighter than steel ) with reduced handling requirements for GRP |
| Compression Strength | Despite its lower weight, tension, flexure and compression strength of GRP is almost 20 times that of steel with much greater safety factors. It does not deform permanently under high loads. Slow heat transfer allows for even stronger mechanical resistance |
| Slow Heat Transfer & Resistant to Electromagnetic Pulses | It is effective at temperatures between -140oC to +120oC. Resistant to electromagnetic pulses and transfers heat more slowly than steel. Composite materials are excellent insulators having a thermal conductivity 1/60 of a steel product, and do not require earthing |
| Zero Halogen, UV & Corrosion Resistance | GRP is resistant to UV and corrosion, and is zero halogen. It is also available in low smoke classified material |
| Offer & Design | Available in 3m and 6m lengths. Full range of pre-manufactured bends, jointing bays and transitions available for fast installation. Dedicated design facility to support bespoke solutions |
mita Benefits
- Health & Safety – GRP presents reduced risk of staff injuries due to its lightweight, easy to cut, no hot works requirement, no deburring and no sharp edges
- Low Installation & Transport Costs – Typically between 30-40% less than steels with easier cutting, drilling and no deburring, painting or earthing
- Long Life & Low Maintenance – Composites are corrosion resistant and maintenance free. MITA GRP products are designed and manufactured to withstand a majority of chemicals & extreme weather – without requiring further maintenance. No rusting, even when exposed to salt spray, H25, acid build up from exhaust gases or brake dust
- Fire Performance – GRP is zero halogen. It has low heat and electrical conductivity, and is available in self extinguishing and low smoke material
- Simpler Installations & Modifications – MITA GRP solution offers a far easier installation, without the need for painting, earth bonding or special tools. Supplying 6m or 3m lengths reduces amount of couplers required
 |
GRP cable ladders manufactured by MITA are available in heights from 100mm to 150mm with widths from 150mm to 1000mm |
| Cable tray and troughing manufactured by MITA is available solid and slotted bottom, and in depths from 60mm to 210mm with widths from 50mm to 400mm. |  |
 |
GRP (Glass Reinforced Polymer) provides excellent resistance to fire and the effects of corrosion.
|
As a comprehensive manufacturer of corrosion resistant industrial cable support products, Wibe Group have the solutions and expertise to specify a suitable solution, and deliver a product which can support any type of power circuit, cable, data and instrumentation.
|
 |
 |
As well as being the perfect accompaniment to other MITA industrial support products, this range of Channel Support Systems is ideal for mounting other industrial service items such as pipework and ducting. Fibstrut™ has high rigidity coupled with an excellent load bearing to weight ratio and of course is totally resistant to a wide range of corrosive agents.

GRP Cable Support Solutions for every application with MITA
GRP (Glass Reinforced Polymer) cable support systems manufactured by MITA possess unique properties which enable them to resist many corrosive environments, particularly where conditions indicate that conventional materials may not provide an economic service life.
Constructed from glass reinforced thermoset resins, GRP is designed and manufactured with a structural integrity normally only associated with steel, but without their corrosion, weight and electrical conductivity problems.
As GRP is non conductive, there is no concern of transmitting electricity into the support system from damaged cables. Additionally there is no requirement for special support conditions to prevent electrolytic corrosion. Non conductive and non magnetic features mean a safer support system.

MITA Cable Support System Applications
What is GRP?
GRP is the abbreviation of Glass 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 – GRP is resistant to most chemicals, stretching and shrinking, resistant to mildew and abrasion as well. When it is reinforced with glass, it becomes a structural polymer. The range is composed of ladders, trays or so called troughs in rail business language and it can support any type of power and data cable runs.
GRP is manufactured by MITA through a process called pultrusion
Resin Types
MITA offers 4 main resin types to accommodate the requirements of various industrial applications which can be in chemically aggressive, demanding heated environments.
 |
POLYESTER Type 2 | Referencing Convention: Ending with PY2 This type of polyester is for general applications, is resistant to corrosion suitable in industries using heavy chemical and caustic materials, and resistant to UV light by nature. |
| POLYESTER Type 1 | Referencing Convention: Ending with PY1 This type of polyester has better fire retardance which makes it suitable for railway, trackside and any other application requiring UL94 compliance and 5VA classification. |
|
| POLYESTER Type 1 Carbon Loaded | Referencing Convention: Ending with PY1C This type of polyester has anti-static properties as it contains carbon powder. It, therefore, requires grounding. It is for on-shore and off-shore oil and gas applications which are classified as explosive environment. |
|
| MODIFIED ACRYLIC | Referencing Convention: Ending with MX This type of polyester has anti-static properties as it contains carbon powder. It, therefore, requires grounding. It is for on-shore and off-shore oil and gas applications which are classified as explosive environment. |
