We understand the importance of having high quality raw materials in order to ensure long lasting products and finishes; this is why we have created a laboratory of our own to verify our material´s chemical composition.

Steel is an iron-carbon alloy with considerable concentrations of other alloys. In the global market, there are thousands of different steels made up of several compositions and/or thermal treatments, that´s why it is important to know their real composition.

We also offer Chemical Steel Analysis to our customers and suppliers, this is used to determine the amount of carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, nickel, aluminum, cobalt, copper, niobium, titanium, vanadium, tungsten, lead, tin, magnesium, arsenic, zirconium, bismuth, calcium, cerium, antimony, tellurium, boron, zinc, lanthanum, iron that exist in a sample.

The results are given in percentages units, for example:



The most important uses of zinc are: to alloy to other metals and to protect other metals as a coating.

For the analysis of a sample whose content is zinc, Metelmex offers the service of Chemical Analysis, which helps to determine the amount of aluminum, copper, lead, tin, cadmium, iron, indium, magnesium, manganese, nickel, antimony, titanium, chromium and thallium that exists in the sample.


This type of analysis is used to determine the percentages of the chemical elements that exist in a sample. This method consists in detecting the characteristic wavelength of each of these elements when a spark excites their electrons.

The base (Fe) and (Zn) Chemical Analysis can be carried out in our laboratory.

Spectro Equipment, which is innovative and adaptable, is used in a wide variety of fields, including metallurgy, environmental, as well as quality control.
