TR80+ Floor Deck
TR80+ Floor Deck

Description

 Initially added to our product range in 2002, the original TR80 has undergone further research and development, evolving to the popular TR80+ profile in use today. This 80mm deep trapezoidal profile offers long un-propped spans reducing the number of structural support members required, making it a popular choice for low to medium storey buildings.

Deflection – This table is based on concrete poured to a constant thickness and does not take account for deflection of the decking or supporting beams (as a guide, to account for the deflection of the decking, a concrete volume of span/250 should be added to the figures indicated). Concrete Weight – These tables indicate concrete weight only and do not include the weight of decking or reinforcement. Concrete weights are based on the concrete densities specified in BS EN 1991-1-1 as follows: Normal Weight Concrete – 2550kg/m. (wet) and 2450 kg/m. (dry). Lightweight Concrete – 2050kg/m. (wet) and 1950 kg/m. (dry).
