PRODUCT INTRODUCTION
The Hot-Dipped Galvanized PC Strand offers an exceptional low relaxation characteristic, meticulously crafted from seven galvanized round steel wires. These wires boast outstanding corrosion resistance, significantly enhancing the lifespan of components, especially in corrosive environments like coastal areas. This technique is globally recognized as an effective method for corrosion prevention, adhering to both current and international standards.
This standard is ideal for use in bridge cables, fixed tension components, and tension parts in buildings, as well as other prestressed structures. Note: It's not suitable for direct use in concrete grouting constructions. Available diameters include 12.7mm, 15.00mm, 15.7mm, 17.8mm, with strength classes of 1770MPa, 1860MPa, and 1960MPa.
The 1x7 and 1x19 hot-dipped galvanized prestressed steel strand series features impressive tensile strengths reaching up to 1860MPa. These strands adhere to the same specifications as plain and round PC steel strands in performance levels, aligning with standards such as GB/T 33363, ASTM A416, EN10138, BS5896, and NFA35-035, among others.
PRODUCT FEATURES
Our product can be customized to meet customer requests for zinc coating levels. The zinc coating can achieve 250 gsm or more, with the uniformity of the layer reaching 3-4 times without any copper exposure. Adhering strongly, the coating remains intact without peeling, even after winding 8 circles post-zinc coating.
Leveraging our company's state-of-the-art equipment, we tailor the galvanizing process to fulfill unique user demands regarding zinc layer quality and surface perfection.
In contrast, uncoated PC steel strands show red rust after a 24-hour salt spray test, unlike our galvanized variant.
Observe the sample evolution of both uncoated and galvanized PC steel strands after a rigorous 21-day neutral salt spray test.
PRODUCT APPLICATIONS
These robust products are designed for usage in construction engineering and coal mine roadway support, even under the harshest environmental conditions.
This innovation supports the world's first 160m low wind speed experimental high tower located in Shandong.
