SMS group and Lamina y Placa Comercial SA de CV, part of the Villacero Group, have successfully completed the hot commissioning of the revamped galvanizing line in Apodaca in Mexico. For the project, SMS supplied a new four-high inline skin-pass mill, a new tension leveller, new fluid equipment and new electrical and automation systems. The project consisted of four consecutive phases, starting with the relocation of the existing equipment on a new bridge structure, thus allowing the installation of the new foundations and equipment, including cold commissioning, to be executed in shadow mode with the line in production. Thanks to this solution, the overall shutdown period could be reduced to a minimum.
The revamping of the galvanizing line allows Lamina y Placa Comercial to meet the growing demand for skin-passed products. The company is now able to produce skin-passed strips, galvanized profiled sheet and coils, galvanized steel roof ridge cap, and pre-painted coils and sheet for structural engineering. Enhanced strip surface quality, improved flatness, and better thickness and elongation accuracy and control are the main benefits of the plant modernization.
The Mexican manufacturer is now in a position to supply the market with galvanized steel SAE 1006, 1008 and 1010 and steel strip products with yield strengths between 210 and 560 MPa, thicknesses from 0.23 up to 2.0 millimetres and widths from 812 to 1,282 millimetres.
