Product Details

GFRP is a better option than traditional galvanized steel in high risk environments such as subsea tunnels or where groundwater has a high chloride content.





 



HEALTH & SAFETY



Safety and occupational health are rightly at the forefront of our work. Anyone who has lifted a steel rockbolt knows how heavy they are. There is still a lot of manual handling in bolting operations. GFRP has a much lower density (25% of steel) so using GFRP bolts reduces the potential harm from prolonged manual handling of rock bolts.



 





  



 



ENVIRONMENTAL IMPACT



As we become more aware of our negative impact on the environment, there is a growing need to reduce this impact. One of the ways to do this is to use products which have inherently less impact on the environment, such as GFRP. After studying, GFRP bolts could have up to 40% less environmental impact than an equivalent twin coated steel bolt. In part this benefit arises from the lower weight of the GFRP bolts which weigh a quarter of the equivalent steel bolts. However, GFRP was better in all ten categories examined and not just in terms of embodied carbon ,What is less well known is that it also featured GFRP bolts as the permanent rock support.

APPLICATIONS



There are different types of GFRP bolts, such as solid GFRP bolts, Hollow GFRP bolts,GFRP Spin bolts,Self-drilling GFRP bolts, Cable GFRP bolts,Injection GFRP bolts,GFRP Bolts Mesh,GFRP rebar reinforcement,etc.



1. GRFP BOLTS is widely used in highways, bridges, airports, terminals, stations, water conservancy projects, underground engineering and other fields



2. Suitable for corrosive environments such as sewage treatment plants, chemical plants, electrolysis tanks, manhole covers, and coastal defense projects.



3. Suitable for military engineering, confidential engineering, special engineering, etc.
