Introduction of Characters:
Pre-stressing Plain Steel bars/Prestressed regular steel bars, also known as prestressed steel bars or high-strength steel bars, which are used in constructions to increase the strength and durability of concrete structures. Made from high-carbon steel, these bars of high-tensile, low-relaxation, smooth are specifically designed to withstand the tensile forces exerted on concrete. The prestressing process involves applying compression to the concrete before it is subjected to the more common tension forces. This is usually done by embedding prestressed steel bars in concrete and then stretching and anchoring them at both ends. This process puts the concrete in a state of compression, which helps offset the tensile forces the structure will experience over its lifetime. Prestressed plain steel bars are available in various diameters and strengths to meet different construction requirements in compliance with PrEN10138-2:2009,BS5896:2012,ABNT NBR 7482:2008, etc. It is important to consult with a structural engineer or construction professional to determine the specific requirements for prestressed plain steel reinforcement in a project because the design and implementation of prestressed systems requires specialized knowledge and expertise.
ltem Description:
Pre-stressing Steel bars, in compliance with PrEN10138-2:2009,BS5896:2012,ABNT NBR 7482:2008, etc.
high-carbon, smooth, cut to length, in packages with weight approx.1250kg with maritime package;
Diameter: 3.0mm - 11.0mm;
Length: as required (+2/-0 mm);
Tensile Strength: 1470MPa. - 1860 MPa.
Key Parameters& Reference Standards：
| PLAIN WIRE | ||||
| Nominal Dia.(mm) | Tensile Strength (MPa) | Relaxation (1000h) | Min. Elongation at Max. Load | Standards |
| 4.0, 5.0, 6.0, 7.0, 7.5, 8.0, 9.0, 10.0, 11.0, 12.0 | 1470、1570、1670、1770、1860 | Low relaxation≤2.5% | Agt≥3.5% | GB/T5223, ASTMA421, BS5896 |
Applications:
They are frequently used in the construction of bridges, high-rise buildings, parking
lots, railway sleepers, the PHC concrete pilings/tubes and other large, complex
concrete structures, etc.
Advantageous:
By introducing prestressed ordinary steel bars into concrete construction members,
the overall material usage can be reduced, cracks can be minimized or
disappeared, spans can be increased, structural stability can be enhanced, and the
overall load-bearing capacity of the structure can be improved.
To sum up, prestressed ordinary steel bars, or prestressed ordinary steel bars, are basic elements in the construction and engineering of reinforced concrete structures.
These steel bars play a key role in improving the performance and longevity of a wide range of civil and construction projects by introducing tension into the steel before it is embedded in concrete.
