Fibrelite, the world's leading and largest manufacturer of composite manhole covers fights metal theft!

Fibrelite’s lightweight, incredibly strong fibreglass composite covers with zero re-sale value in the scrap market are the perfect metal theft deterrent.

The increase in metal costs has stimulated the theft of metal manhole, trench and gully covers. Metal theft is now having a serious impact on the global economy through inflated insurance premiums, high repair and replacement costs as well as causing extremely serious health and safety hazards.

Fibrelite is strategically placed to utilise its quality, high volume manufacturing facilities in the UK, US and Malaysia to offer a very cost competitive alternative to metal that can benefit all affected industries. Fibrelite has manufactured and sold globally over 250,000 covers.

Fibrelite first pioneered the composite covering system in 1980 and set the standard by which performance is now measured. Fibrelite initially developed the composite cover for petrol station forecourts to withstand the wheel loading of heavy goods vehicles and from there quickly went on to be adopted worldwide. Fibrelite is considered as the industry standard by the major oil companies and continues to lead the way in composite innovation.

Having established a global reputation for high quality products and superior after sales service the company has held accreditation to both the ISO quality standard and British Standards Kite Mark since 1998. Fibrelite is the first composite cover manufacturer to have KIWA approval.

Fibrelite’s covers comply with the requirement of BS EN 124:1994, classes C250 & D400 and provide an excellent anti slip/skid surface which is guaranteed for the life of the cover, with a value of Polished Skid resistance Value (PSRV>50 when in wet conditions) which meets the requirements of HA 109/09, part 5.

The covers are manufactured in a close mould environment combining long strand multi-directional fibreglass with a specifically formulated resin matrix to produce an extremely durable but lightweight, approx. 1/3rd the weight of a steel or cast iron cover. The covers are inert so will not corrode, are not electrically conductive and have low thermal conductivity. Highly effective in covering manholes, gullies and trenches that contain cable, wire or fluid and perfect for where access is required as they are such a lightweight alternative to metal and concrete. They are unaffected by underground gasses and most chemicals, particularly those involved with sewage.

Global Expansion

Fibrelite announced earlier this month it has expanded global operations with the opening of a new Malaysian production and service facility in order to meet accelerating demand. In addition to this new facility, Fibrelite also has a 30,000sq ft. factory in the UK and a 35,000sq ft. plant in the US.

Cost Benefits

Although composite is initially more expensive than metal, the monolithic structure of a Fibrelite cover means they will not delaminate or corrode. With a minimum guaranteed lifespan of 15 maintenance free years, these covers are a ‘fit and forget’ product that can be fully lockable. So when considering the total cost of ownership, composite covers represent excellent value for money versus metal.

Typical Applications

To provide a guide, typical applications include: access for electrical junction boxes, access points for piping, airport meter pits, catch basin covers, sanitary access covers, fuel tanks, grease trap covers, leak detection covers, meter pits, monitoring wells, non-conductive electrical drawpits, oil water seperators, pipe trench covers, piping sumps, removable planking, sewer access, submersible pumps, tank gauge covers, underground chambers, underground communication boxes, valve boxes.

Recent Customer Quotes

“We were looking for an installation to replace our ageing duct covers. Fibrelite came up with this solution and it is manufactured and sourced locally.”

“I was impressed with how easy the install was and couldn’t believe how light the covers were whilst still being able to hold 40 tonne loadings.”

“We are very happy with this solution. We do not need a forklift truck anymore to remove the concrete slab and can get to the geothermal installation in a minute.”

“We are working with Fibrelite to retrofit our older vaults. The Fibrelite covers met an important need to find a light, durable, temperature, corrosion and abrasion resistant cover that seals out the surface water.”
