Overview
The construction and infrastructure industry requires rigorous testing of materials — reinforcement steel, concrete, structural steel, cables, and fasteners — to ensure structural integrity and compliance with Indian building codes and international standards.
JRAGRAU provides testing machines and force measurement instruments to construction material testing laboratories, ready-mix concrete plants, structural engineering firms, and government testing facilities across India.
Our UTMs test everything from TMT bars and wire rope to prestressing strand and structural bolts, while our load cells support structural load monitoring, pile testing, and anchor pull-out verification on active construction sites.
Reinforcement Steel & Bar Testing
Testing of TMT bars and reinforcement steel is one of the highest-volume applications for UTMs in India. Every construction project requires material test certificates for the reinforcement used.
JRAGRAU UTMs for rebar testing offer: • Tensile testing per IS 1786 — yield strength, UTS, elongation • Bend and re-bend testing per IS 1599 • Capacities from 400 kN to 1000 kN for all bar diameters • Automated report generation with load-elongation curves and pass/fail against IS specifications
Our rugged testing machines are designed for the high-throughput demands of construction material labs, testing hundreds of samples daily with minimal operator intervention.

Structural Load Monitoring
Beyond laboratory testing, JRAGRAU sensors are deployed in the field for structural and geotechnical monitoring:
Pile load testing — Compression load cells measure the load applied during static pile load tests, verifying foundation capacity per IS 2911.
Anchor pull-out testing — Load cells integrated into pull-out rigs verify anchor capacity in concrete and rock.
Structural health monitoring — Load cells and pressure sensors embedded in bridges, tunnels, and dams provide long-term structural health data.
Tower and crane monitoring — Crane load cells provide real-time overload protection for construction cranes and hoisting equipment.
Our sensors are available in IP67 stainless steel construction for outdoor and underground environments.
Cable, Wire & Strand Testing
Prestressing strand, wire rope, and structural cables are critical to bridges, pre-stressed concrete structures, and lifting operations. Testing these products requires high-capacity UTMs with specialized grips.
JRAGRAU supports cable and wire testing for: • Prestressing strand tensile testing per IS 6006 • Wire rope breaking strength testing per IS 2266 • Galvanized wire tensile and wrap tests • Stay cables and tendons for bridge construction
Our high-capacity UTMs (up to 1000 kN) with hydraulic gripping systems provide secure specimen holding without jaw breaks, ensuring valid test results.
