'- Korea's first and only technology to manufacture coil springs by securing them to leaf springs of cargo vehicles (Holding Patent) 

'- One B&R Tech coil spring increases the loading capacity by 990KG for Porters, 780KG for Bongos

'- It is difficult to increase the load by more than 200kg with a single leaf-spring reinforcement (the B&R Tech coil spring is superior in terms of price and function)

'- B&R Tech coil springs are recommended for trucks that transport heavy loads or in areas with many unpaved roads (Korea has numerous mountainous areas and about 81% of truck drivers have overloading experiences) 

'- Cold-Work Coil Production

'- Powder coating plating technique for corrosion prevention
