There have been a multitude of manufacturers and specs for Tee Rail over the years; below you will find some important data to help identify rail sections. The type of most rail can be easily identified by referring to the dimensional diagrams on this page. The Tee Rails sections data table lists basic dimensions and identifies mill marks usually rolled onto the rail web.
