PRSteel – Welded Reconstructed Beams

PRSteel is a MOMSteel registered brand of welded reconstructed beams (PRS), with constant or variable inertia, made to measure and available from 3 to 16 metres and complying to standards  EN ISO 9001 e EN 1090. The configuration of this beam’s web allows us to considerably increase the resistance capacity in comparison to other conventional solutions in L shape, allowing the use of lower thicknesses, thus decreasing the weight and the price for the service. As well as this, the existing flexibility regarding the optimization of the flanges, also contributes to a more competitive final price.

MOMSteel is currently a reference in Portugal in the manufacturing of metal structures, the fruit of many years of experience in the metalworking sector. In its industrial unit in Abrantes, from the Engineering to the Production, the watchwords are innovation and efficiency, to make everything a lot simpler and easier for the clients.
