Steel excellence in every wire

Welcome to the core of Remer’s quality control: our Testing & Analysis Laboratory, where every incoming wire and every rope produced undergoes rigorous checks, tests and inspections, according to precise and transparent standards.

Here, advanced technology and specialist expertise come together to ensure optimal performance and material safety.

From zinc mass testing using the Keller-Bohacek method, to complex mechanical tests for twisting, bending, tensile strength and breaking load, every testing step is essential to determine the strength, reliability and regulatory compliance of our products. Our laboratory is not just a control center: it is a daily commitment to excellence, quality and customer satisfaction.
Only the best is good enough!

Chemical tests

Zinc mass test
(Keller-Bohacek method)

The reaction vessel consists of a bulb test tube ending with a graduated scale tube. The test tube is filled with a hydrochloric acid solution. Through the upper stopcock, the specimen is then introduced: a piece of galvanized steel wire of a defined length.

When the rapid reaction is complete, pressure is equalized using the leveling vessel and, by difference, the amount of hydrogen released is read. A table supplied with the apparatus indicates the correspondence between the cubic centimeters of hydrogen produced and the amount of zinc in g/m² for a given length, taking into account specific temperature and atmospheric pressure values measured in the laboratory.

Physical tests

Wire torsion

The test consists of twisting a straightened wire, with a length 100 times greater than its diameter, around its own axis in one direction, applying a tension not exceeding 2% of the nominal tensile strength class, and verifying that the number of twists is greater than or equal to the value required by the standard.

Wire bending

Wires of the various classes must withstand the number of alternating bends specified by the standard, depending on their diameter. The standard also sets the bending radius of the supports according to the wire diameter.

Wire strength

The test consists of winding the wire around the grips of the testing machine; one grip remains fixed while the other is driven by an electric mechanism that pulls the wire to failure. Software processes the test data and calculates the wire’s strength and elongation.

Wire tensile test

The test consists of clamping a wire sample between two grips, one fixed and the other pulling. The load is measured on a dial with a scale indicating the value in kgF of the wire’s actual strength up to failure (this machine can test up to 10,000 kgF).

Cable tensile test

The test consists of winding the cable in a spiral around the grooves of two wheels, one fixed and the other rotating thanks to a hydraulic mechanism. The load is measured on a dial with a scale indicating the value in kgF of the cable’s actual strength up to failure (this machine can test up to 10,000 kgF).

Cable breaking test

The test consists of subjecting a length of rope to a tensile load until failure, in order to determine the rope’s actual breaking load. The load must be increased progressively so that the unit load increase does not exceed 100 N/mm² per second, until 80% of the minimum breaking load is reached.

Above 80% of the rope’s minimum breaking load, the load must be increased uniformly so that the unit increase does not exceed 10 N/mm² per second. The rope’s actual breaking load is the maximum load reached during the test.
