Uses of UM Steel Plates

The strength of UM steel plates makes them well-suited for a variety of structural and building projects. For example, the UM process allows for plates to be produced in substantial lengths that can be used in constructing girders. UM Steel Plates can also be shaped into different tools and objects. Steel suppliers like California Steel Services understand the importance of choosing the right material for your projects.

The specific project requirements will be the primary factor in determining the thickness and weight per foot. Environmental conditions, such as temperature and exposure to other weather elements also should be considered when deciding on grade. If the possibility of corrosion is a concern, look for a plate with a more resistant make-up such as galvanized, stainless steel, or aluminum, rather than others that are more susceptible to the elements.
