Product Introduction
Unveiling the marvel of innovation, the 1x7 structure "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand is meticulously engineered with a special anti-corrosion grease and sheath. These cutting-edge steel bars are pivotal in the realms of water conservancy and hydro-power projects, providing unmatched durability and resilience. With the burgeoning expansion of wind power projects, the construction heights of wind power towers now challenge or surpass the 120m mark. Consequently, the employment of concrete towers utilizing advanced external prestressing technology has seen a surge in the use of our unbonded prestressed steel strands. Their exceptional prowess in resisting corrosion and fatigue not only ensures fortified wind resistance but also significantly extends the operational lifespan.
Aligned with the esteemed JG/T 161-2016 Unbonded Prestressed Steel Strand standard, we've pioneered a transformative design that revolutionizes sheath tensile property testing. This groundbreaking innovation enhances practicability and efficiency, streamlining processes and maximizing project safety and quality. performance of the sheath. This breakthrough effectively standardizes quality parameters, ensuring rigorous project safety and elevating the overall quality assurance of endeavors.
Product Characteristics
Tailor-made for the outer cables of wind power concrete towers, our unbonded steel strand features customizable sheath and grease thickness, precisely crafted to meet user-specific technical requirements. The sheath boasts a dense, smooth finish, subtly showcasing the steel strand's outline. It exemplifies superior surface quality, adhering to stringent standards: devoid of air holes, mechanical damage, cracks, and conspicuous wrinkles, thereby ensuring flawless performance.
