"Using Lewis Deck was a simple way of allowing us to have the solid upper floor we wanted to our new home"
A LEWIS DECK composite floor consists of the LEWIS cold rolled steel sheet covered with a relatively thin layer of C20/25 fine grade aggregate concrete or CA25/ F4 free flowing, self levelling liquid screed.
During the curing period the LEWIS deck acts as shuttering, but once the concrete/ screed has cured, locking into the LEWIS deck, it forms an extremely strong, composite, structurally sound floor, i.e. it becomes reinforcement for the concrete/ screed. The use of fine grade aggregate concrete can also provide a monolithic finish to provide a “finished floor” option. The overall depth of a LEWIS composite floor can be relatively thin – 50 mm in most cases (without UFH pipework).

What are the Lewis Deck sheet sizes?A
Q: What sheet sizes are held in stock for delivery within a few days after order? A: We stock 2500mm and 1300mm sheets. These are all 630mm wide and 16mm deep. Deliveries are made via the pallet network directly to site. The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT. 2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*. (*2.5m sheet only) For larger projects we are able to produce bespoke sheet sizes if required, please get in contact to discuss other options for sheet sizes.Q
Why don't my Lewis sheets interlock like they do in the video?A
Q: Why don't my sheets interlock like they do in the video? A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.
