FEATURES AND ADVANTAGES:

l Light in weight (1/4th weight of steel rebar)

l High strength to weight ratio

l High corrosion resistance

l Fire retardant

l No electrical conductivity

l Lower maintenance cost

l Lower transportation fee

l Easy cutting

l Proper bonding to concrete

l Good thermal insulation

l Able to Mold into Complex Shapes

APPLICATION FIELDS:

GRP high stength mining rock bolts and bits

Based on features above, FRP rebar appears to be promising alternative to steel reinforcement in concrete structures such as marine structures, parking structures, bridge decks, highway under extreme environments, subway tunnel ,airport construction,Waterway Engineeringand structures highly susceptible to corrosion and magnetic fields.
