Introduction: Is FRP Grating Really More Expensive?
Many buyers wonder whether FRP grating is really more expensive than steel.
The short answer is: it costs more at first, but saves much more over time.
FRP grating doesn’t rust, doesn’t need painting, and lasts for decades with little maintenance.
When you look at the total cost — not just the purchase price — FRP can reduce overall expenses by 30–40% across its lifetime.
Let’s break down how the cost works, what affects the price, and why it offers better long-term value than steel grating.
1. Understanding the Real Cost of FRP Grating
When comparing materials, price per square meter doesn’t tell the whole story.
FRP grating costs are shaped by several key components:
a. Material Cost
FRP grating is made from resin and fiberglass.
Different resins bring different prices:
Vinyl Ester – best corrosion resistance, highest cost.
Isophthalic – balanced performance and price.
Orthophthalic – budget choice for general use.
Higher fiberglass content improves strength but also raises cost.
b. Manufacturing Process
Molded FRP Grating: economical, suitable for most projects.
Pultruded FRP Grating: higher precision and load capacity, slightly pricier.
c. Transport and Installation
FRP is about four times lighter than steel, meaning:
Easier handling and transport.
No heavy lifting equipment.
Lower labor costs and faster installation.
d. Maintenance
FRP requires almost no maintenance.
It doesn’t corrode, doesn’t need repainting, and keeps working in harsh environments — a major long-term advantage over steel.
2. FRP vs Steel Grating: Cost Over Time
Let’s look at a 1,000 m² industrial platform over 20 years:
| Cost Item | FRP Grating | Steel Grating |
|---|---|---|
| Purchase | $30,000 | $20,000 |
| Installation | $5,000 | $8,000 |
| Maintenance (10 years) | $2,000 | $15,000 |
| Replacement (after 20 years) | $0 | $20,000 |
| Total (20 Years) | $37,000 | $63,000 |
FRP’s initial cost is higher, but it saves about 40% over the full lifecycle — especially in corrosive or coastal environments.
3. 2025 FRP Grating Price by Region
| Region | Price Range (USD/m²) | Notes |
|---|---|---|
| China | $18 – $30 | Depends on resin and thickness |
| Middle East | $35 – $60 | Includes logistics |
| USA / Europe | $50 – $90 | Higher compliance and labor cost |

4. What Affects the Price
Resin type and quality
Thickness and load rating
Grating type (molded or pultruded)
Surface finish and coatings
Custom sizes and colors
Certifications like ASTM, ISO, or BS 476
5. The Long-Term Economic Value
FRP grating brings savings beyond its price tag:
No maintenance or repainting
Lighter weight reduces structure and shipping costs
20–50 years of service life
Non-slip, non-conductive, fire-retardant
Environmentally friendly and recyclable
These benefits make FRP a long-term investment, not just a material purchase.

Conclusion
FRP grating isn’t the cheapest option — but it’s the smartest one.
It saves money, time, and maintenance over the years, making it ideal for ports, wastewater plants, and chemical industries.
Think beyond price. Think long-term value.
FRP grating is an investment that pays for itself.
