GRP Rebar

Alcomet supply GRP Rebar (aka FRP Reinforcing Bar) for use within concrete structures.

Fiber reinforcement bar is made from high strength glass fibre reinforced with vinyl ester resin. The core of the rebar has all the reinforcing fibre (70%wt) along the length of the bar for maximum strength. A helically recess in the surface of the rebar is created in the production process which does not damage the core fibre and is sufficiently deep to give a key to enable the concrete to have a mechanical grip on the rebar.

The stock rebar is supplied in it’s natural unpigmented colour of the resin / glass composite which is a translucent beige. Other colours can be ordered if you are colour coding different ares of a site for example.All the various dimensions are all supplied in standard 5mtr lengths but can be cut to size to suit your requirements.

GRP Rebar is available as standard or with a sanded finish.

Benefits for using GRP over traditional steel reinforcements

• GRP is non conductive which is beneficial within electrical installations such as substations.
• GRP doesn’t need earthing in electrical applications unlike tradition steel reinforcement.
• GRP  is non corrosive which can vastly increase the lifespan of the concrete structures, saving time and money.
• GRP is only 25% of the weight of steel alternatives allowing faster more cost effective installation and also making it a much more environmentally friendly alternative.
• GRP tensile strength is equal to or exceeds that of equivalent steel.

Common applications for GRP rebar

• Applications requiring low electric conductivity or electromagnetic neutrality – electrical substations, bases for transmission and telecommunication towers, railroad crossings, specialised military structures.
• Structures built in or close to sea water – piers, jetties, docks, off shore platforms, decks.
• Weight sensitive structures – construction in areas of poor load bearing soil, remote locations, sensitive environments or seismic areas.
