Composite solutions for infrastructure designed to last.
IMARA develops project-ready construction solutions and supplies composite materials for civil, industrial, transport and energy infrastructure.
Product ecosystem
Five systems. One engineering approach.
From reinforcement inside concrete to the poles supporting critical networks, every range is selected around real project conditions.
GFRP Rebar
High-strength reinforcement for durable concrete structures.
- Corrosion free
- Lightweight
- High tensile strength
GFRP Bent Elements
Project-specific elements for accurate reinforcement assembly.
- Project-ready supply
- Accurate geometry
- Faster installation
GFRP Mesh
Lightweight, corrosion-free reinforcement for slabs and surfaces.
- Corrosion free
- Lightweight
- High tensile strength
Polypropylene Macrofibre
Designed fibre reinforcement for concrete performance and crack control.
- Crack control
- Improved durability
- Reduced plastic shrinkage
Composite Poles & Masts
Project-specific structures for power, transport and communications.
- Corrosion resistant
- Project-specific load capacity
- Lightweight
Why composites
Performance where traditional reinforcement is vulnerable.
Composite materials shift the engineering conversation from corrosion management to long-term structural performance.
TRADITIONAL STEEL
Maintenance begins with exposure.
- Susceptible to corrosion in aggressive environments
- Higher transport and handling weight
- Conductive and magnetic
GFRP COMPOSITE
Durability is built into the material.
- Complete resistance to reinforcement corrosion
- Approximately 75% lighter than steel
- Electrically non-conductive and non-magnetic
Project calculator
Compare reinforcement before the project reaches site.
Enter the slab geometry and grid layout to estimate reinforcement quantity, indicative material comparison and transport weight.
Delivered cost, weight and truck loads for the selected pair.
| Steel 12 mm | GFRP 8 mm | |
|---|---|---|
| Material | $36,381 | $32,198−$4,184 |
| Delivery | $5,963 | $1,193−$4,770 |
| Delivered total | $42,344 | $33,390−$8,954 |
| Weight | 42,802 kg | 5,463 kg−87.2% |
| Truck loads | 5 | 1−4 |

Assumptions and limits of this estimate
Preliminary quantity, weight and material-cost scenario based on an indicative international composite-material reference. Delivery is an indicative logistics scenario only: full truck loads of 10 t at $2.65 per km, one way, excluding loading, unloading, duties and route conditions. The selected pair is not a statement of structural equivalence and this is not a commercial offer. Final reinforcement, logistics and pricing must be verified for the project.
