troff (/ ˈ t iː r ɒ f /), short for "typesetter roff", is the major component of a document processing system developed by Bell Labs for the Unix operating system. troff and the related nroff were both developed from the original roff.

The Teeroff beam is a more efficient cross section than the Super T beam and has several other advantages whilst retaining the same aesthetic shape of the Super T beam. The advantages of the Teeroff beam have been recognised by manufacturers and contractors resulting in numerous successful completed bridges.

Roff was a Unix version of the runoff text-formatting program from Multics, which was a descendant of RUNOFF for CTSS (the first computerized text-formatting application). [1] roff is a descendant of the RUNOFF program by Jerry Saltzer, which ran on CTSS.

This document provides a summary of the design of a proposed 37m single span bridge with precast concrete T-roff girders. Section 2 describes the bridge design, including using LUSAS MODELLER software to model preliminary box girder sections and layout.

groff (GNU roff) is a typesetting system that reads plain text input files that include formatting commands to produce output in PostScript, PDF, HTML, DVI, or other formats, or for display to a terminal. Formatting commands can be low-level typesetting primitives, macros from a supplied package, or user-defined macros.

Delta has been manufacturing and supplying precast prestressed concrete TeeRoff Beams to numerous Main Roads projects throughout Western Australia since 2002. Projects supplied are located as far north as Kununurra down to Esperance in the far south.

Over the past 15 years, precast pretensioned Super ‘T’ concrete beams with a composite concrete deck has been the preferred superstructure form for typical road bridges throughout Australia, particularly in Victoria.
