EN 10138 is a European Standard series that specifies and verifies prestressing steel products for concrete, such as wire, strand, and bar used in pre- and post-tensioned construction. To match this to your program, talk with our team.
What EN 10138 Covers
The series sets the requirements for prestressing steels, including mechanical properties, tolerances, and the tests used to confirm them. It governs the high-strength wire, strand, and bar that carry prestress in concrete structures.
Testing Prestressing Steel
Verification centres on tensile properties, including tensile strength, proof force, and elongation, tested on full-section wire and strand with grips that hold high-strength product without slip or damage.
Preparing Specimens
Strand and wire are usually tested full-section, so grips and fixturing must handle the high force and the geometry. To configure prestressing-steel testing, request a quote.
Reading the Designation
Cited as EN 10138 with its part and year. Confirm the part relevant to your product form.
