SupFRP DUMAX-Nut - excellent anti-corrosion with superior strength advanced by 60%

GFRP bolts and accessories are using more and more globally wide in mining, tunneling, and civil construction for its advantages of lightness, high strength, anti-corrosion and easily-cutting. However, when higher bearing capacity is required on the GFRP bolting system in relatively complicate soil foundation, GFRP nuts seem not strong enough to support the demand. The traditional way is to use steel nut with GFRP bolt, however, the anti-corrosion is non-comparable to GFRP material. 

 

DUMAX-Nut is invented to cope with the new demand by SupFRP. The new Nut is made by 25% steel and 75% GFRP, in which, the steel part is protected perfectly by the GFRP cover against from air and humidity, while steel provides superior bearing capacity, thus the strength of the whole system could be advanced by 60%.  

 

DUMAX-Nut as a new product which is born to combine the advantages of GFRP and steel material shall provide more options for our customers in different jobs. SupFRP is also committed to create new products and more possibility to satisfy customers’ increasing demands along with development of the markets. 

The application for patent has been accepted. 

 

End Load Test (S25 L100 DUMAX-Nut): 60% higher than traditional GFRP nut
