Stainless Steel Rebars

Main Deficiencies in M.S.

• M.S. is less robust than S.S.
• M.S. is less resilient.
• M.S. has lower corrosion resistance.
• M.S. is less heat resistant.

Stainless Steel Rebars is the only solution which can address the shortcoming of the M.S. Rebars.

Like any other re-bars, S.S. Re-bars does the job of reinforcement. The core structure of any building is made of steel. The S.S. Rebars does not get corroded due to formation of chromium oxide layer on the surface when exposed to atmosphere.

410L (Ferritic stainless steel) are mostly being used worldwide and recently in India, considering the life cycle costing. Stainless Steel 410L Grade can achieve 100 years of life in various corrosive environments with exceptions in marine splash zone and extremely critical regions.

“410L” of Indian Standard is equivalent to Japan-SUS410 “

Why is S.S. Rebars Superior?

• Inherently good corrosion resistance.
• Reduced life cycle cost for concrete structures.
• Good Strength.
• Good weld-ability.
• Good ductility.
• No coatings to chip, crack of degrade.
• No coatings damage to repair.
• No“exposed” cut ends to coat or cover
• Capable of withstanding shipping, handling, bending.
• Good high and low temperature mechanical properties.

S.S. Rebars Application

Properties of S.S. Rebars

Selective substitution

Where a structure needs to withstand a corrosive environment, Stainless Steel rebar can replace carbon steel rebar. This selective substitution can greatly extend the service life of the structure.

A simple substitution of carbon steel rebar with stainless steel will mean

• Identical rebar design and placement
• Identical development length
• Similar rebar pull-out strength
• Higher durability
• Lower maintenance cost

Life-cycle cost

In addition to the initial construction cost, a life cycle analysis takes into account future maintenance and rehabilitation/ replacement cost. The selective use of S.S. Re-Bars will greatly reduce maintenance cost and postpone the need for any major rehabilitation or replacement of the structure. When ‘Disruption’ costs are added to the maintenance costs, the benefits of using stainless steel rebar become increasingly compelling, in the event of major repairs to strategic bridges or elevated highways, disruption costs can include:

• Wasted fuel (when vehicles are idling or are forced to take lengthy detours)
• Employees late for work
• Delayed deliveries of goods
• Lower productivity
• Loss of revenue if traffic on toll bridges or highways is reduced or stopped.
• Additional use of concrete to repair.
• Repair & Maintenance cost.

Selective substitution with S.S. Re-Bars would have greatly reduced future maintenance costs and would have extended the service life to 70-100 years. These significant savings could have been achieved with only a relatively modest increase in the initial project cost. The additional costs of selectively using stainless steel rebar depend on the size and complexity of the structure.

Corrosion Resistance

• Corrosion resistance is important in construction materials, especially for infrastructure near coasts or at high altitude.
• Highly corrosion-resistant due to their Chemical properties.
• Corrosion resistance makes it more durable and longer lasting in harsh environment
• The cost of corrosion in India is estimated to be very high, with infrastructure being a major contributor to this cost.
• Corrosion rate of less than 0.5 microns year, making S.S. Re-Bars highly corrosion resistant

Durability and lifespan

• longer lifespan resulting in lower maintenance costs and longer service life.
• Durability due to ductility, corrosion resistance and high strength.
• Lifespan of up to 100 years or more.
• Cost of Lifecycle of structure can be reduced by up to 50%.
• Country like Japan also use SUS410 equivalent to “Grade AISI 410 L” of Indian Standard.

Strength and Ductility

• High strength and ductility, makes it suitable for use in high- stress application, such as bridges and coastal roads
• The strength allows to withstand high loads and stresses
• Ductility to deform without breaking, makes is important in seismic performance.
• The combination of strength and ductility makes a better choice for infrastructure near coasts or at high altitude, where high stress and seismic activity are common.
• Improves the seismic performance of a structure, reducing the risk of collapse during earthquakes.

Environmental benefits

• Recyclable - which can reduce the Environmental impact of construction projects.
• Reduction in the need for frequent maintenance and repairs resulting saving of resources
• world’s most recycled material, with a recycling rate of around 88%.
• These environmental benefits make it a better choice for sustainable construction. Being durable material, can reduce the need for frequent maintenance and repair, reducing waste and conserving resources
