The Problem with Conventional Steel Reinforcement
Steel rebar fails in floor and slab environments for three reasons:
- Corrosion under slabs groundwater and moisture cause steel to rust from within, cracking the concrete above.
- Chemical exposure factory and warehouse environments accelerate steel corrosion, degrading floors faster than designed.
- High maintenance costs failed industrial floors mean costly repairs and expensive operational downtime.
What is GFRP Rebar?
GFRP — Glass Fiber Reinforced Polymer — is a composite rebar. It consists of glass fiber and polymer resin. It is available as straight bars, bent bars, and mesh. MRG Composites is India's first BIS-licensed GFRP rebar manufacturer — a proven, code-compliant material ready to specify.
A base slab sits between subgrade and the floor above — 100 mm to 500 mm thick — distributing building loads and blocking groundwater. It demands long-term strength, moisture resistance, and stability.
How GFRP's properties directly address road construction demands
Corrosion resistant
does not rust in contact with water, salts, or soil chemicals.
2× tensile strength
does not rust in contact with water, salts, or soil chemicals.
¼ the weight
faster handling and lower installation labour costs.
Non-conductive
safe for electrically sensitive environments.
Low maintenance
no spalling, no repair cycles over the slab's service life.
Industrial floors in factories, warehouses, and manufacturing plants endure heavy machinery, forklift traffic, chemical spills, and thermal cycling daily. Steel-reinforced floors crack, corrode, and need frequent repair.
How GFRP's properties directly address highway construction demands
Chemical resistance
inert to acids, alkalis, oils, and industrial cleaning agents.
High load capacity
2× the tensile strength of steel handles heavy machinery and constant traffic.
Thermal stability
no expansion and contraction cycle, reducing thermal cracking.
Zero maintenance
no rust, no spalling, no corrective repairs needed.
GFRP Bars vs. Steel Rebar
| Property | Steel Rebar | GFRP Rebar |
|---|---|---|
| resistance | Corrodes with moisture & chemicals | Fully corrosion-resistant |
| Tensile strength | Baseline | 2× higher |
| Weight | Heavy | ¼ of steel |
| Conductivity | Conductive | Non-conductive |
| Lifespan (harsh environments) | 15–25 years | 50+ years |
| Maintenance cost | High | Near zero |
| Upfront cost | Lower | Higher — lower lifecycle cost |
