Fiberglass rebars,FRP rebars,GRP rebar, Composite rebars
Various sizes of fiberglass rebars ( GFRP rebar, composite rebar) ,diameter from 6mm to 38mm, 8 years of experience in different applications
Pulwell manufactures composite R-bars by combining the pultrusion process and an in-line winding & coating process for the outside sand surface. The FRP composite rebar is made from high strength glass fibers along with an extremely durable vinyl ester resin. The glass fibers impart strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. For improved stiffness and mechanical properties a carbon/vinyl ester or Epoxy product is also available. FRP rebar significantly improves the longevity of civil engineering structures where corrosion is a major factor.
Pulwells GFRP rebar Features & Benefits:
1.High Strength-to-Weight Ratio provides good reinforcement in weight-sensitive applications.
2.Non-Corrosive will not corrode under exposure to a wide variety of corrosive elements including chloride ions.
3.Non-Conductive provides excellent electrical and thermal insulation.
4.Excellent Fatigue Resistance performs very well in cyclic loading situations.
5.Good Impact Resistance resists sudden and severe point loading.
6.Magnetic Transparency is not affected by electromagnetic fields. Excellent for use in MRI and other types of electronic testing facilities.
7.Lightweight easily transported and assembled in the field without need for heavy lifting equipment.
Pulwells GFRP Rebar Applications:
Six general categories of applications have been identified for which FRP reinforcement are suitable alternatives to steel, epoxy-coated steel, and stainless steel bars:
1.Reinforced Concrete Exposed to Deicing Salts-FRP bars can eliminate the corrosion problems and reduce maintenance and repair costs in northern climates where deicing salts are used every year on roads and pavements. Applications most likely to benefit include: parking structures; bridge decks; jersey barriers, parapets; curbs; retaining walls and foundations; roads and slabs on grade; and many others.
2. Structures Built in or Close to Seawater-Corrosion of steel reinforcement is a common problem in structures built in or close to seawater. Examples of possible applications: quays; retaining walls; piers; pilings; jetties; caissons; decks; bulkheads; floating structures; canals; roads and buildings; offshore platforms; swimming pools and aquariums.
3. Applications Subjected to Other Corrosive Agents-Chemical processing industries of all types, as well as wastewater of domestic or industrial origin, constitute major sources of corrosion for steel reinforcement. Typical applications include: wastewater treatment plants; petrochemical plants; pulp and paper mill and liquid gas plants; pipelines and tanks for fossil fuel; cooling towers; chimneys; mining operations of various types, nuclear power plants; and nuclear dump facilities.
4. Applications Requiring Low Electric Conductivity or Electro-magnetic Neutrality-Using steel bars in applications where low electric conductivity or electromagnetic neutrality is needed often result in complex construction layouts, if such use is possible at all. Potential applications are: aluminum/copper smelting plants; manholes for electrical and telephone communication equipment; structures supporting electronic equipment such as transmission towers for telecommunications; airport control towers; magnetic resonance imaging in hospitals; railroad crossing sites; and military structures needing radar invisibility.
5. Applications in Tunneling / Boring Requiring Reinforcement of Temporary Concrete Structures: Structures including mining walls; underground rapid transit structures and underground vertical shafts.
6. Applications in Weight Sensitivity or Thermally Sensitivity Structures: Concrete construction in areas of poor load bearing soil conditions, remote geographical locations, sensitive environmental areas, Apartment patio decks; thermally insulated concrete housing and basements; thermally heated floors and conditioning rooms, or active seismic sites posing special issues that the use of lightweight reinforcement will solve.
