PRODUCT INTRODUCTION
Hot-Dipped Galvanized PC Strand low relaxation prestressed steel strand is made of seven hot-dipped galvanized round steel wires with good corrosion resistance, which can effectively extend the life of components in the state of corrosive environments such as coastal areas, which are recognized as an effective form of corrosion prevention in currently and internationally.
This standard applies to bridge cables, fixed tension components, lifting or fixing tension parts of buildings and other prestressed structures, which is not directly used in concrete grouting constructions, diameter: 12.7mm, 15.00mm, 15.7mm, 17.8mm, strength class: 1770MPa, 1860 MPa, 1960MPa.
The structure of 1x7, 1x19 hot-dipped galvanized prestressed steel strand series products, the tensile strength which can reach 1860MPa and same specifications as plain&round PC steel strand in terms of performance levels ACC. to GB/T 33363, ASTM A416, EN10138, BS5896 and NFA35-035 etc.
PRODUCT FEATURES
The product can be produced as per the requests of zinc coating from customers, zinc coating can reach 250 gsm or above, the uniformity of the zinc coating layer is 3-4 times without exposing copper, and the adhesion does not break and does not peel under the condition by winding 8 circles after zinc coated.
Depending on the company's advanced equipment, we can design the galvanized process to meet the special requirements of users on zinc layer quality, surface quality, etc.
Compared with the PC steel strand without coating and galvanized PC steel strand, the former appeared red rust after a salt spray test for 24 hours.
Sample changes of PC steel strand without coating and galvanized PC steel strand after 21 days of neutral salt spray test.
PRODUCT APPLICATIONS
The products can be used in construction engineering and coal mine roadway support engineering under harsh environmental conditions.
The world's first 160m low wind speed experimental high tower in Shandong.
