The Timberless-33 floor system is the lightest cold-formed steel system on the market today. The Timberless-33 system is ideal for taller structures in order to maintain a light foundation and reduce the supporting elements of the foundations and/or podiums such as geo piers, spread footings, pilings, beams, columns, etc. Lower weight delivers less foundation impact and ultimately less cost to the owner/developer. Additionally, the Timberless-33 system is ideal for areas of extreme winter weather conditions, as it can be dried in quickly with one trade driving the critical path.
