TR50 Floor Decking
TR50 Floor Deck

Description

 This profile should only be used as formwork, where the reinforcement within the slab has been designed by the structural engineer, taking no account of the metal decking. 

Benefits

• Formwork for non-composite RCC floor and roof slabs

• Optimised cover width for speed of installation

• Flexible side-lap detail for control of cover width 

Gauges

 • 0.7mm

• 0.8mm

• 0.9mm

• 1.0mm

• 1.2mm 

Specification

• 950mm cover width

• 50mm deep 

Steel Grade

• S250

• S350 

tr50

Finishes

  • Galvanised (Z275)
  • Interior Liner

Fire Design

With TR50 being a formwork-only profile, the fire design and reinforcement required must be determined by the structural engineer designing the slab. In the table below the concrete weight is based upon concrete density of 26kN/m³ allowing for 1kN/m³ of reinforcement.

This table is based upon concrete poured to a constant thickness and does not take account of deflection of the decking or supporting beams – as a guide, to account for the deflection of the decking, a volume of span/250 should be added to the figures indicate in the Concrete Volume and Weight table. Concrete weight indicated does not include the weight of the deck profile. Overall slab depth includes deck profile
