The reinforcing steel DURA550 is suited for constructional elements
exposed to splash water and stationary water (use of defrosting salt) and
for areas jeopardized by carbonatization. DURA550 presents a reliable
and economic solution for improving the corrosion resistance of reinforced
concrete significantly and thus extending their lifetime. DURA550 can be
projected and handled according to the methods developed for black rebars.
No special treatment on the construction site is necessary.
Extend the lifecycle and reduce costs
In construction, the current trend is increasingly a far-sighted approach. The costs of future structural maintenance –
the lifecycle costs – are frequently considered during the design phase. DURA550 aim is to improve the durability of
structures and thus avoid future maintenance work.
DURA550 helps you protect your Concrete Structure
DURA550 is an innovative reinforcing steel with significantly improved corrosion resistance and best-in-class lifecycle
costs, developed by India Steel. DURA550
