Enter the R51+ profile!

 In News

We are delighted to announce the launch of the new R51+ reentrant profile as a welcome addition to our range of decks. The original R51 profile has been part of our floor deck range for many years but now, with improved structural efficiency, the R51+ is lined up to take over.

The R51+ offers the same core benefits as its predecessor; excellent slab load carrying capacity, shallow slab depth option (100mm minimum for 1-hour fire rating) and flexibility for shear stud placement due to 150mm trough spacings. However, it now comes in S350 and S450 grades and thicknesses from 0.8mm to 1.2mm. Following a two-year period of development and intensive testing, the R51+ is now ready to perform on site.


Technical improvements
The new profile includes a percentage of additional steel to help form the trough stiffeners running down the profile troughs and rib embossments. These new additions result in an average of 5.8% improved spanning capabilities, the best performance for its specification on the market.

The Construction Stage graph below represents the comparison of the new and old profile. The new 0.8mm gauge value engineering option performing just short of the old 0.9mm gauge, the new 0.9mm is like-for-like to the old 1.0mm gauge and the new 1.2mm gauge setting the standard, far outperforming the previous option.


New order

The R51+ is available now and is supported with product data which can be found on our website. We’ll be glad to provide quotations for the R51+ deck on any new contracts with reentrant profile requirements.
