With regards to experience, our team is amongst the most technically qualified anywhere in the world – the self drilling anchor bolts that we produce for the mechanical industry reflects this experience.
We produce self drilling anchor bolt through the electric arc furnace route. The raw material mix is chosen and prepared carefully to ensure the highest standards of cleanliness. All heats are ladle refined and vacuum degassed before continuous casting and rolling. Right through the production process, we maintain full traceability of the material and a record of the tightly controlled process parameters. This ultra-clean steel forms the starting point for the manufacture of our tubes and hollow bars.
