Sand-coated composite rebar

More and more construction companies use composite rebar in their projects. Manufacturers of composite rebar try to keep up and develop products with up-to-date materials and technologies.However, most manufacturers still concentrate on ribbed rebar whereas only a few can develop and launch a more innovative product: composite rebar with sand coating.

Advantages

Higher resistance to corrosion, alkali and acids

Sand coating enhances anti-corrosiveness and protection from aggressive environments which are typical for concrete and construction mixes even further

No itching hands any more

And no need to use extra PPE

Up to 40% higher adhesion with concrete

Small particles of sand which are distributed equally all over the rebar surface make it more rugged and thus enhance adhesion with concrete by up to 40%

Higher pullout strength

Extended life-cycle

80 years minimum. Additionally, sand coating enables protection from UV light which normally destroys the epoxy matrix over time with other types of non-protected rebar.

9 times lighter than steel, 3 times stronger than steel

Tensile strength is three times higher than A400C steel provided that the weight is up to four times smaller with an equal diameter and 9 times lighter with a ‘substitution factor’

Non-magnetic, very low heat thermal conductivity

FRP is dielectric in nature which means that it does not create Radio Magnetic Interference and does not conduct electricity. FRP has a very low thermal conductivity coefficient so constructions keep warm in winter and cold in summer

50% more cost-efficient than equally functional bigger diameter of steel rebar

Cost-efficiency is achieved by a number of factors: smaller procurement costs, faster and less voluminous logistics, loading/unloading and installation works with less machinery and less manhours

More comfortable and more rational logistics

Diameters of up to 10mm are supplied in 100m coils of upto 1.5m in diameter and weight of up to 10kg.

Custom length

Rebar is supplied in rods and coils of custom length

Expansion similar to that of concrete

Steel reinforcement gradually deforms its concrete environment due to difference in coefficients of linear expansion. FRP’s coefficient of linear expansion is similar to that of concrete so concrete and reinforcement form a unanimous environment

RP keeps its strength if bent

FRP does not lose the linear shape if rolled into coils which makes transportation and installation very comfortable

Fast, easy and comfortable to install

FRP rebar does not require too much workforce or too many tools to work with: disk grinder, pliers and scissors are enough for fast and comfortable work with a full range of diameters
