SF-Tec #3 G40 Poly Rebar

SKU: 181403
Regular price $5.49

SF-Tec #3 Poly G40 Rebar is a horizontal use rebar. This SF-Tec #3 G40 rebar is Grey in Colour and is engineered for flatwork and is a non-structural bar that is coated with a polyester coating. It is made with a corrosion proof glass to help reinforce your concrete with a superior grade product. 

It is rust proof and will help to eliminate spalling and corrosion cracks. This rebar will last for generations with an easy and quick installation.  SF-Tec #3 G40 bar is lighter than steel rebar and will save in transportation and installation costs..  SF-Tec #3 Poly G40 Rebar should not be used in areas where standing water is prevalent. This rebar is stamped with it's rating.

For Conrete Reinforcement

FRP (Fiberglass Reinforced Polymer) is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass (in fiberglass), basalt, carbon, or aramid. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic. 

FRP bar has been developed as a non-corrosive alternative to steel for concrete reinforcement. FRP bar is suitable for any structural or architectural application where a material that is corrosion resistant, lightweight, or non-conductive is required. 

FRP bar is the ideal solution for concrete reinforced projects, such as bridges, barrier walls, decks, diaphragm walls (soft eye), tunnel segments, garages, pavements, Wharfs, sea walls, wave breakers retaining walls and fence systems.
