FRP vs Steel: Total Cost Analysis for 20-Year Projects
FRP vs steel cost is an important question that infrastructure planners in India are facing today. With the country’s infrastructure budget rising to ₹10 lakh crore (≈US$120 billion) in 2023–24, the decision-makers are focusing on both upfront prices and long-term value.
India’s growth through smart city projects, industrial expansion, and public works is driving demand for durable and low-maintenance materials. Due to steel’s low initial cost, it has been the go-to material. However, its high maintenance, risk of corrosion, and frequent replacements make it less attractive over time.
Fiber Reinforced Polymer (FRP) is slightly more expensive at the start. But it offers exceptional resistance to corrosion and requires minimal upkeep. Let’s discover more about the 20-year FRP vs steel price for infrastructure projects.
Initial Material Costs: FRP vs Steel
When comparing initial FRP vs steel cost, steel appears cheaper. Standard mild steel grades in India usually range from ₹80 to ₹110 per kg. This makes it an ideal choice for budget-conscious projects.
On the other hand, FRP components like pultruded panels, gratings, or rebars fall in the range of ₹150–300 per kg. This indicates that FRP is 50-150% more expensive than steel initially. However, the upfront cost does not close the debate between FRP vs steel price.
FRP is 70-80% lighter than steel, which reduces the transport costs, simplifies handling, and reduces installation labour by up to 30%. While FRP parts can be installed quickly with basic equipment, steel requires cranes, welding, and larger crews. When these ancillary costs are taken into consideration, the initial gap narrows. In many cases, projects even achieve cost parity during installation.
Maintenance & Repair Costs Over 20 Years
Now that you are aware of the initial FRP vs steel cost, let’s focus on their maintenance and repair costs.
Steel
Steel is vulnerable to corrosion, which strains the ongoing expenses, compounding over time. Indian environments are characterised by high humidity, coastal salinity, and industrial pollutants. Hence, steel structures need comprehensive maintenance programs, like:
- Rust Treatment and Prevention: Annual costs of ₹50-100 per ton, which escalate in corrosive environments.
- Regular Repainting Cycles: Every 3-5 years for structural protection, which costs ₹200-400 per square meter.
- Protective Coating Renewals: Specialised coatings lasting 8-15 years before complete renewal.
- Inspection and Monitoring: Regular assessments to prevent catastrophic failures.
FRP
Creative Fibrotech’s FRP products virtually eliminate maintenance requirements over their operational lifespan. Corrosion immunity means no rust treatment, protective coatings, or painting cycles. The maintenance profile includes only:
- Periodic Visual Inspection: Minimal costs, primarily for safety compliance.
- Occasional Cleaning: Standard maintenance procedures without specialised treatments.
Strength & Durability Comparison
FRP vs steel price also excel in strength and durability. Steel has superior compressive strength and stiffness (high modulus), which makes it reliable for heavy loads. However, it requires fireproofing and rust protection, and its strength degrades with corrosion.
FRP is lightweight yet exceptionally strong in tension. For example, fibreglass-reinforced rebar can reach tensile strengths around 1000 MPa, far above typical steel rebar (400-600 MPa). This high tensile strength means FRP elements can be designed to be strong and light.
FRP structures also ensure harsh environments. They are 100% non-corrosive and resist acids, salts, and alkalis. As a result, FRP bridges or grating in coastal or chemical plants can last 50-100+ years. On the other hand, steel components might fail in 20-30 years without extensive maintenance.
FRP parks and street benches are extremely common today. They are weatherproof and do not require any maintenance. Plus, they can be customised in colour or even wood-like finishes. They do not warp, rust, or resist graffiti, unlike wood or metal benches.
Lifecycle Cost Analysis: 20-Year Projection
The comprehensive FRP vs steel cost analysis reveals a compelling economic advantage over 20 years. While steel appears cheaper initially, the total cost of ownership strongly favours FRP:
| Total Cost | Steel: ₹22,00,000 | FRP: ₹16,00,000 |
|---|---|---|
Initial Material |
₹8,00,000 |
₹13,00,000 |
Installation |
₹4,00,000 |
₹2,50,000 |
Maintenance |
₹5,00,000 |
₹50,000 |
Replacement |
₹3,00,000 |
₹0 |
Downtime |
₹2,00,000 |
₹0 |
In short, FRP is highly cost-efficient, with the break-even point typically occurring within 8-12 years depending on environmental conditions. Projects in harsh environments achieve payback even faster due to accelerated steel degradation.
Environmental & Sustainability Factors
Beyond the FRP vs steel price, there are also environmental and sustainability factors one needs to consider. FRP production consumes much less energy than steel making. This leads to roughly 40% lower embodied CO2 per kilogram. It is lightweight, so transport requires less fuel.
Although FRP recycling is still evolving, end-of-life protocols allow many FRP products to be recycled rather than landfilled. Crucially, FRP’s long lifespan means far fewer replacements, which shrinks material turnover and waste.
For example, engineers note that over a 50-year span, FRP structures can emit only a fraction of the carbon steel structures would. Many governments and industries now prioritise such “green” attributes. FRP’s lower carbon footprint and reduced maintenance-driven pollution make it attractive for eco-conscious projects.
