Why Stainless Steel Rebar
• Rebar products reduce the lifetime cost of the structure
• Rebar products reduce the maintenance-related downtime
• Rebar products have a wide range of dimensions and alloys.
There are three main cases where stainless steel is the best choice:
1. When concrete is subject to the ingress of chlorides from either marine environments or de-icing salts. Stainless steel rebar can resist the initiation of corrosion with chloride concentration levels more than 10 times higher than that which carbon steel can resist.
2. When concrete loses the high alkalinity that protects the carbon steel from corrosion due to carbonation. This can take more than 100 years but ultimately is inevitable, making stainless steel the ideal solution for structures requiring a very long lifespan, for example temples and monuments.
In addition, the stainless-steel rebar has much better ambient and low temperature energy absorption, fatigue resistance, and toughness than carbon or alloy steels, which is important in applications where there are seismic, security, and other impact resistant considerations. It also has improved stiffness and strength retention in fire compared to carbon steel.
Using stainless steel rebar in these environments reduces the lifetime cost of the structure, as well as maintenance-related downtime.
Quality and standards:
Our manufacturing program is supported by in-house product inspection and testing, and the extensive expertise of our technical team.
We offer rebar according to BS 6744, BS 8666, and ASTM A955. Marcegaglia supplies mill test certificates with every bundle delivered and our mills are accredited to recognized international standards, including:
• ISO 9001: 2008 (TUV Nord)
• CARES Certificate of Approval for production of rebar
• CARES Certificate for sustainable reinforcing steel
• Kontrollrådet product type approval
Environmental Product Declaration:
LEED (Leadership in Energy and Environmental Design) is the most widespread program of voluntary certification systems for environmentally friendly buildings. Using Marcegaglia stainless steel products can contribute credits towards LEED certification.
