Longspan Lintels are a group of pre-engineered, precast, prestressed, laminated concrete beams.
Our Longspan Lintel range was originally developed from the Windeck and Winstep product ranges, which gave us exposure to the various structural challenges faced by engineers and building contractors.
Hamish Scott Consulting Engineers initially specified our prestressed, precast Winstep and Windeck beams to provide structural support in a number of “Longspan” applications. Three Windeck DB 250 beams were laminated together with galvanised steel bushes, through the lightening holes, to provide a 230mm wide composite Winlin bearer beam for double garage door apertures. We further refined this design to form the ‘Slimlin’ (3 beam) laminated system, specific for 4800mm wide garage door applications. In 2012 word of mouth ignited demand amongst Contractors as this simple, fast erection system eradicated long curing times and provided a fast, hassle free method of beam construction, thereby saving time and cost of shuttering and propping.
In 2013 the launch of our ‘Kwiklin’ laminated beam system took place, which consisted of a two-part prestressed shutter beam, for longer, heavier duty, beam applications. This system is available in three wall-width options in lengths of up to 9 meters and consists of a reinforced concrete infill (placed post erection). The Kwiklin was initially designed and engineered by Messrs Colin Dunn and John Brittain and later refined by Herman Pietersen.
All Longspan lintels are manufactured with class 3, 50Mpa reinforced concrete, precast and prestressed at our facility just outside of East London. The result is a fit-for-purpose structural lintel, which satisfies most structural beam requirements.
Our Longspan Lintels have been used in many large-scale construction projects in the Eastern Cape, such as schools, clinics, hospitals as well as domestic dwellings spanning double garages, stack-away doors, sliding doors, etc. TFSD is a local manufacturing company, which can proudly boast another range of unique innovative fast track construction products for our built environment.
