Heavy structural steel beam metal fiber laser engraving

This is a section of structural iron beam. Beam is 2” thick and 24” high, weights around 500 lbs as result project was quite unusual and normally LaserCutZ does engraving on more light weight items. Interestingly enough this beam came right after we did fiber laser engraving for Brooklyn Navy Yards rail road rail which has same shape and same idea but is smaller and weights much less. This structural metal beam was fiber laser engraved for NYC local iron works company, to be used as a gift and sign for the project that they finished. Engraved letters in this metal go quite deep too as result job required lots of machine hours
