Frequently Asked Questions
What sizes of galvanised dowel bars are available?
Our galvanised dowels are available in R12, R16, R20, R24 and R28 diameters, each in a choice of standard lengths from 300mm to 600mm. We also offer custom cutting for complex projects.
How does galvanising protect dowel bars from corrosion?
Galvanising protects dowel bars by adding a layer of protection between the bar and the elements. This is done through hot-dip galvanising, where a dowel bar is placed in molten zinc, which coats the bar in a protective layer. All of our bars comply with AS/NZS 4680 coating thickness standards for extra peace of mind.
What's the difference between dowel bars and deformed reinforcing bars?
Deformed bars have an uneven surface, whereas galvanised dowel bars are smooth. Galvanised dowel bars are best used where load transfer is crucial, such as in pavements and industrial floors, whereas deformed bars give concrete structural reinforcement, such as in slabs, beams or walls.
Can you supply galvanised dowel bars for large commercial projects?
Yes, we can. Sydney Reo has experience supplying major commercial and infrastructure projects. We can handle any custom cutting you might require, and can supply you with bulk orders of galvanised dowel.
How quickly can you deliver galvanised dowel bars to my Sydney site?
