Fiberglass Rebar adopt glass fiber as reinforced materials and  polyester resin as basic materials, through Pulled by specific traction machine, be solidified glass fiber reinforced plastic rod body with full thread under high pressure and high temperature by preformed matched die . It is made up of fiberglass anchor rod plus resin anchoring agent, tray and nut.
The Solid Bolt is used in Mining, Tunneling and Civil Engineering widely. It provides more possibilities as an alternative to metal. The GFRP Solid Bolt is manufactured with high quality GFRP material(Glassfiber Reinforced Polymer). The GFRP Solid Bolt have a high tensile load and bearing capacity with accessories, but the weight is only one quarter of metal product.
 
Applications    
Fiber glass rebar, FRP rebar, GFRP rebar, Composite rebar,reinforcing bar with diameter from 4mm to 55mm.manufactures composite Rebars by combining the pultrusion process and an in-line winding & coating process for the outside sand surface.  As compared to con-ventional steel rebars, composite rebars should be a suitable alternative to steel reinforcing in:
 ·Architectural Concrete: cast stone, architectural cladding, balusters, column facades, window lentils, architectural precast elements, hand railing, and statuary and fountains, etc.
 ·Concrete exposed to de-icing salts in: bridge decks, railroad grade crossings, median barriers, parking garage elements, and salt storage facilities, etc.
 Concrete exposed to marine salts in: seawalls, water breaks, buildings & structures near waterfront, aquaculture operations, and floating marine docks, etc.
 ·Applications Subjected to Other Corrosive Agents: Wastewater treatment plants; petrochemical plants; pulp/paper mills; liquid gas plants; pipelines / tanks for fossil fuel; cooling towers; chimneys; mining operations of various types; nuclear power and dump plants.
 ·Applications Requiring Low Electric Conductivity or Electromagnetic Neutrality: Aluminum and copper smelting plants; manholes for electrical and telephone communication equipment; bases for transmission / telecommunication towers; airport control towers; magnetic resonance imaging in hospitals; railroad crossing sites, and specialized military structures.
 ·Tunneling / Boring Applications Requiring Reinforcement of Temporary Concrete Structures: Structures including mining walls; underground rapid transit structures and underground vertical shafts. 
 ·Weight Sensitive Structures: Concrete construction in areas of poor load bearing soil conditions, remote geographical locations, sensitive environmental areas, or active seismic sites posing special issues that the use of lightweight reinforcement will solve. 
 ·Thermally Sensitive Applications: Apartment patio decks; thermally insulated concrete housing and basements; thermally heated floors and conditioning rooms.

Method of application for FRP rock bolt
After the roofbolter finished drilling, remove the drill pipe, make the six-party of rock bolt installation machine insert jumbolter drill pipe connection, then make the lever genus part of compression nut insert the rock bolt installation machine, make anchoring agent into the rock bolt holes, then use the rock bolt bracing anchoring agent, at this time do propulsion leg movement, drilling machine motor not rotating, anchoring agent will be sent to the bottom of the hole, at this point to start drilling machine motor rotating, rotating rock bolt to stir anchoring agent, when the FRP rock bolt reached the bottom of the hole, stop the machine, drilling machine fast rotating to stirring anchoring agent, stirring time is set time of anchoring agent (usually 10 s ~ 15 s ), close the drilling machine, stop rotating, according to the anchoring agent curing time, general stop 30 s ~ 45 s, after anchoring agent curing, ant then make drilling machine to start rotating, screw up the nut for bottom of rock bolt, at this time drilling machine motor stop rotating, rock bolt install end
Safety matters need attention
1. When installation the rock bolt, not allowed holding the rock bolt, lest produce an accident
2. Finished the rock bolt, when the drilling machine drops, can't make the hand on the gas leg, prevent hurting hands
3. When use the jumbolter to installation tray and nut, must master the use of the drilling machine and anchoring agent, when install the nut must immediately stop the machine, otherwise it will damage FRP bolt
4. Please use the resin bolt anchoring agent that complies with safety srandards
5. Transportation store
6. In the process of product transportation shall not be cast and throw.
7. The rod body should be stored in a cool and dry place, rod body storage time no more than one year.
8. End of the anchoring can not contaminated with oil, rod body tail thread shall not damage

   Hollow grouting bolt characteristics
 1. The function of bolt and grouting pipe is combined, when grouting, it is grouting pipe, after grouting,
    no need to dial out to become a bolt.
2. The hollow design enables the anchor rod to realize the grouting pipe function, avoids the mortar
    loss which the traditional construction craft pipe grouting causes.
3. Grouting full, and can realize the pressure grouting, improve the quality of the project.
4. Because of the role of accessories, the middle of the rod is very good, mortar can anchor the whole
    body wrapped, to avoid the risk of corrosion, to achieve long-term support purposes.
5. Convenient installation, without on-site processing of thread, you can easily install the plate, nut.
6. Combined with the special bolt grouting pump and grouting technology, it is the anchor system
    which has solved many problems of traditional anchor support at home.
