PRODUCT INTRODUCTION
The Hot-Dipped Galvanized PC Strand is crafted using a low relaxation prestressed steel strand composed of seven precisely engineered wires. These hot-dipped galvanized round steel wires boast exceptional corrosion resistance, significantly prolonging component lifespan in corrosive environments such as coastal areas. Internationally acclaimed as a robust corrosion prevention method, these strands ensure durability and reliability.
Ideal for bridge cables, fixed tension components, and various prestressed structures, this standard supports a range of diameters (12.7mm, 15.00mm, 15.7mm, 17.8mm) and strength classes (1770MPa, 1860MPa, 1960MPa) and is not directly used in concrete grouting constructions.
Featuring a versatile 1x7 and 1x19 structure, these hot-dipped galvanized prestressed steel strand series offer incredible tensile strengths up to 1860MPa. These strands match the performance specifications of plain & round PC steel strands, adhering to top international standards such as GB/T 33363, ASTM A416, EN10138, BS5896, and NFA35-035.
PRODUCT FEATURES
Tailored to meet your specific needs, the zinc coating on our product can reach 250 gsm or more. The coating's uniformity remains intact without copper exposure, and the adhesion remains robust even after winding 8 circles, without breaking or peeling.
Thanks to our cutting-edge equipment, we customize the galvanization process to meet users' special requirements regarding zinc layer quality and surface aesthetics.
Compared to uncoated PC steel strands, our galvanized version exhibits dramatically enhanced resilience, showing no red rust even after 24 hours of salt spray tests.
Observe significant improvements in galvanized PC steel strands against untreated ones with notable differences after a 21-day neutral salt spray test.
PRODUCT APPLICATIONS
Our products excel in construction engineering and coal mine roadway support under harsh environmental conditions.
This engineering marvel stands as the world's first 160m low-wind-speed experimental tower, located in Shandong.
