Threaded steel PSB930-50 bridge high yield strength non longitudinal ribbed steel bars
Threaded steel PSB930-50 bridge high yield strength non longitudinal ribbed steel bars Post-tensioning is a form of prestressing. Prestressing simply means that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the... -
PSB950/1050 PT bar for tunnel construction soil anchor/rock bolt
PSB950/1050 PT bar for tunnel construction soil anchor/rock bolt Through these environmental considerations, stress rod and post-tensioning techniques not only increase the strength and durability of building structures but also contribute to more sustainable and environmentally friendly building practices. Post tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms befor... -
D20mm 500MPA All threaded rebar for construction
D20mm 500MPA All threaded rebar for construction Impact of environmental stress on seagrass: For example, pharmaceuticals such as ibuprofen entering the marine environment may have an impact on seagrass. Studies have shown that high concentrations of ibuprofen can cause increased oxidative stress in seagrass, affecting its photosynthesis and metabolite production, thereby affecting its ability to adapt to other environmental stressors. Through these environmental considerations, stress ro... -
PSB930 THREADED STEEL BAR BARRA HELICOIDAL PRODUCERS from Guotai Metal
PSB930 THREADED STEEL BAR BARRA HELICOIDAL PRODUCERS from Guotai Metal Post tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. Afterwards, once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete. Post-tensioning is a ... -
1230Mpa Screw Thread Steel Bar for post tensioning
1230Mpa Screw Thread Steel Bar for post tensioning Stress Bar Post-Tensioning: Stress bar post-tensioning systems are a cost-effective solution for applying post-tensioning forces on short straight tendons without any profiles. They are used for a range of applications, including pre-cast connections in buildings, temporary and permanent bracing, and pre-stressed beams and columns The thread bars used in the system are made from high-strength steel and are bonded to the surrounding concret... -

The difference between high Strength Thread Bar System and ordinary threaded steel bars
The appearance of hot rolled thread bar is slightly different from ordinary threaded steel. Hot rolled thread bar not have longitudinal ribs, so it can be directly connected to nuts. Application of the Post Tension Bar Post-tension bars are used in various applications within the construction industry to enhance the strength and durability of concrete structures. Here are some of the key applications of post-tension bars: Prefabricated Tendon Systems: Wire-based tendon systems provide solut...
