FIBERGLASS REBAR (GFRP) Glass Fiber Reinforced Polymer
Kodiak (GFRP) E-CR Fiberglass Rebar is Highly Structural, Non-Corrosive, Non-Magnetic, & with more than 200% strength with less than 25% weight vs steel
America’s #1 Fiberglass Rebar & Basalt Rebar Manufacturer – Since 1984 –
KODIAK Fiberglass Rebar / CR-GFRP (Corrosion Resistant Glass Fiber Reinforced Polymer) - Made with Premium Corrosion Resistant E-CR glass, Kodiak FRP is the best concrete reinforcement for any application, especially those where concrete is exposed to water, salt water, or chemical environments. Kodiak rebar does not corrode, weaken or dis-color. Kodiak Fiberglass Rebar is 25% the weight of steel rebar with twice the tensile strength of steel rebar. GFRP rebar is Non-magnetic, Non-Conductive to electrical current & thermal transfer, & transparent to (RF) radio frequency. These characteristic qualities have made GFRP Rebar standard protocol for use in MRI facilities, power transmission terminals, precision calibration, toll-roads as well as any area in which magnetic equipment & radio frequency is present. GFRP rebar is the concrete reinforcement of reputable pre-cast concrete manufacturers for quality production.
FIBERGLASS REBAR COST
The most critical cost consideration in comparing Fiberglass rebar vs Steel rebar is the weight per lineal foot is substantially lower & tensile strength properties are higher. GFRP rebar has more than 300% greater linear footage per ton when compared to steel rebar. Fiberglass rebar cost comparison should also factor: tensile strength is more than 200% of its steel counterpart.
Fiberglass Rebar Mechanical Properties
(GFRP) Fiberglass Rebar has 200% Tensile Strength @ 25% weight, GFRP vs. Steel Rebar. - Non-Corrosive & Non-Conductive -
The effective yield strength of FRP rebars should be calculated based on the following reduction factor, r
fye =Effective yield strength of FRP rebars fye = r fult
fult = Ultimate strength of FRP rebars obtained from the average, of a minimum of six samples of the same size or values given in Table 6.1

Green Building with Clean Technology
Using Advanced Materials in Infrastructure Design is the Key to Building Green... Sustainable Building !
Responsible Building with Kodiak FRP Rebar – Sustainable Infrastructure for the Future of America
Using Advanced materials in design is the key to building green...Sustainable Building!
There is not a legitimate argument in the facts. Infrastructure development using Kodiak FRP rebar is the most economical option. Anything less is short sighted cost analysis projection. Ignoring service life cost projection is a display of defiance to fiscal logic, an adolescent or lazy mentality that we just can not afford as a society in progress. Kodiak GFRP reinforcement initial cost is fractionally higher on front end budget calculation. With that said... Analyzation of cost to service life savings when accounted, convert to an astronomical fiscal return on program investment.
Too often, critical working life cost analysis is dismissed or minimized by carelessly short sighted budget politics over-ruling or ignoring the best interests of the peoples national infrastructure longevity & sustainability. Save a buck today & kick the can, spend 5 times as much next time to demolish & rebuilt again, and Again &... Again. Its is just tax revenue, free money right? Wrong... Now is the time for responsible planning. Its time to scrutinize service life projections critical to long term value engineering with use of high quality, efficient materials for the infrastructure of our country, our home.
The Carbon footprint of steel in production is much higher than that of FRP rebar production, even without consideration of the footprint left by demolition & rehabilitation time & time again. Not to mention the carbon offset provided in the ability to use less concrete in the initial structure by a thoroughly strategized engineering design.
Green Building with FRP Concrete Rebar In The USA, from the Beginning
Kodiak FRP Rebar is the first fiberglass rebar made in the USA, from which Testing & application standards as used in ACI440 were set. The Mckinleyville Bride of Buffalo Creel was first vehicular bridge in the U.S. using only GFRP concrete reinforcement (WV Mckinleyville bridge 1996) for the U.S. Federal Highway Department with The University Of West Virginia's Dr. Hota GangaRao
FRP Fiberglass Rebar is the "Hybrid" concrete reinforcement noted for its high tensile strength, light weight , Non-Corrosive, & Non-Conductive properties. KODIAK Fiberglass rebar was the first structurally viable Fiberglass rebar developed & produced in the United States. 1982, Leroy applied his extensive knowledge in structural plastics & years of experience in the field of plastics pultrusion moved with the idea of industry change for infrastructure sustainability. 1984 Leroy Heston stepped forth with Kodiak Fiberglass Rebar, as the most effective solution to the US’s crumbling bridge infrastructure. Over time, chloride salts used to de-ice bridges slowly penetrate bridge concrete to its steel reinforcement. When chlorides chemically react to steel rebar, rust is formed expanding as it reacts. The expansion of rust exerts tremendous internal pressure from the inside of the concrete structure eventually causing the concrete to crack, ultimately causing structural failure shortening the working life of the structure
