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 befo... -
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... -
OEM Supply Hot Rolled Steel Bar - PSB1080-40 for coal mine roof rock bolt/connecting bar/Rock nail – Cathay
PSB1080-40 for coal mine roof rock bolt/connecting bar/Rock nail A threaded bar can be used as a ground anchor by drilling a hole into the ground and inserting the bar deep enough to provide sufficient stability for whatever is being anchored. This could be anything from a small tent or canopy to a large sign or billboard. The bar is typically secured in place with concrete, soil, or other materials that provide enough friction to prevent it from being pulled out of the ground by force. Depen... -

100% Original Factory Ground Anchor Screw Thread Steel Bar - Grade 830 32mm Fully Thread Pc Bars – Cathay
Grade 830 32mm Fully Thread Pc Bars Post tension bars are designed to create a compressive force within the concrete that helps to counteract the tensile forces that the structure will experience over time. This can improve the integrity and longevity of the concrete structure, making it more resistant to cracking, corrosion, and other forms of damage. Post tension bars are typically made from high-strength steel and are placed inside precast concrete sections or cast-in-place concrete forms... -
