Servo-hydraulic universal testing machine Tensile strength test of
steel strands for prestressed concrete
Test Objectives
Determination of Mechanical Properties Through the tensile test,
precisely derive the mechanical property indices of steel strands,
encompassing tensile strength (the ultimate strength under peak load), yield strength (the stress corresponding to 0.2% plastic deformation), and elongation at break (the deformation capacity of the gauge length post-fracture).
These quantitative data serve as the basis for analyzing the
material's mechanical behavior. Verification of Engineering
Suitability Compare the test outcomes with design codes or relevant
industry standards to assess whether the steel strands comply with
the safety and reliability criteria for practical applications in
fields like bridges, building structures, and prestressed
engineering. This process ensures the stability of engineering
structures.
Test Standards
GB/T 5224-2014, GB/T 228.1-2021, ASTM A416/A416M-21, ISO 6934-1
Price advantage
We increase our own research and development efforts, built
processing center, produce the core parts independently, so we
could reduce link costs with the same quality. Our good quality
products could save you much more than some other low price but bad
quality products. Reducing the failure rate of the machine to
reduce the customer's maintenance costs, but also improve the
efficiency of the machine, this price with high quality could give
customers real benefits.
Service advantages
A full range of services making customer satisfaction reflect our
professional. Pre-sale, we provide comprehensive advisory services,
tailored for different industries to meet customers’ special needs.
After-sale, we could supply door to door installation and training
services according to customer requirements . During the use
process, if there is any problem, your could reach our technical
engineers in time by e-mail, remote video, telephone and other
possible ways. The machine parts is free of charge during the
warranty period ,and machines lifetime maintenance.
