Product Details
Prestressed concrete strand profile:
The Prestressed concrete strand is a stranded steel cable composed of 2, 3, 7 or 19 high-strength steel wires. According to the number of steel wires, it can be divided into 7 wires, 2 wires, 3 wires and 19 wires. The commonly used structure is 7 wires. The commonly used Prestressed concrete strands in Prestressed concrete strands are low relaxation Prestressed concrete strands without coating, and some are galvanized. They are commonly used in bridges, construction, water conservancy, energy and geotechnical engineering, etc. Unbonded Prestressed concrete strands are commonly used in floor slab and foundation engineering.
Prestressed concrete strand features:
The main characteristics of the Prestressed concrete strand are high strength and good relaxation performance, and the other is straight when unfolded. The common tensile strength grade is 1860 MPa, and there are strength grades such as 1720, 1770, 1960, 2000 and 2100 MPa. The yield strength of this steel is also very high.
Prestressed concrete strand parameters:
| Steel strand type | Nominal diameter (mm) | Nominal sectional area (mm) | Mass per meter g/m | Tolerance | Breaking load of specified characteristic value not less than (KN) | The yield load of 1% of the specified characteristic value is not less than (KN) | The load at 1% elongation is not less than (KN) | Small elongation at high load 10 ≥ 500% | Necking at break | When the initial load is 70% of the breaking load, the relaxation rate of 1000h is not more than 1% | |||
| Diameter tolerance (mm) | Cross-sectional area tolerance (mm) | Weight tolerance (mm) | Relaxation Type 1 | Relaxation Type 2 | |||||||||
