PRODUCT INTRODUCTION
Introducing our Hot-Dipped Galvanized PC Strand, an advanced low relaxation prestressed steel strand comprised of seven meticulously crafted components. Each strand is formed from hot-dipped galvanized round steel wires, offering superior corrosion resistance to significantly enhance the longevity of components in challenging environments like coastal areas. This globally recognized method is among the most effective solutions for corrosion prevention today and internationally.
This high-standard product is ideal for use in bridge cables, fixed tension components, or tension parts in buildings and various other prestressed structures. It offers diameters of 12.7mm, 15.00mm, 15.7mm, and 17.8mm, with strength classes of 1770MPa, 1860 MPa, and 1960MPa. However, it is not used directly in concrete grouting constructions.
The 1x7 and 1x19 series of hot-dipped galvanized prestressed steel strands boast a tensile strength reaching an impressive 1860MPa. They feature the same specifications as plain and round PC steel strands, aligning with performance levels according to GB/T 33363, ASTM A416, EN10138, BS5896, and NFA35-035 standards.
PRODUCT FEATURES
Our product can be tailored based on customer requirements for zinc coating, achieving up to 250 gsm or more. The coating uniformity is remarkably consistent, ranging between 3-4 times without exposing copper, while the adhesion remains unbroken and intact even when wound around 8 circles post zinc coating.
Thanks to our cutting-edge equipment, we can customize the galvanization process to accommodate specific user demands regarding zinc layer quality and surface finish.
In contrast to uncoated or simply galvanized PC steel strands, our coated variant resists red rust even after enduring a 24-hour salt spray test.
Observe the sample transformations between non-coated and galvanized PC steel strands following 21 days of neutral salt spray testing.
PRODUCT APPLICATIONS
Our innovative products are designed for use in construction engineering and coal mine roadway support engineering, even under the most severe environmental conditions.
This innovative application was showcased in the world's premier 160m low wind speed experimental high tower located in Shandong.
