ComFlor®  Tata Steel Tata Steel ComFlor® 210 The original deep ultra long span composite profile introduced for the first Slimflor® systems. • Efficient. Cross stiffener technology and deep profile shape provides a very efficient metal deck and composite slab. • Especially suited to bear on the extended lower flange of a steel beam, can also be used on the top flange. • Nestable profile gives low transport and handling costs. High performance deep deck specifically designed for Slimdek® and all other integrated steel beam systems. • Optimised profile design gives superb span capability and...

ComFlor®  Introduction Introducing ComFlor® Composite floor decking systems ComFlor® is specifically designed for rapid installation of flooring and to facilitate lower mass buildings with long clear span composite concrete floors. Large areas of ComFlor® can be easily craned into position and in excess of 400m2 laid by one team per day. With minimal mesh or fibre reinforcement and pumped concrete, the completed floor can quickly follow. Composite floor decks ComFlor® offers the widest range of composite floor decks, from ComFlor® 46 all the way to ComFlor® 100, the Tata Steel range...

BNP Paribas Real Estate HQ, 6 Pancras Square, City of London Steelwork contractor: Severfield Decking installer: Composite Profiles Key benefits: ComFlor® composite floor deck range • The most extensive cost-effective and efficient range of composite floor deck profiles in Europe. • Seven unique profiles enable effective and efficient design. • Fast build time provided by quick installation and prop free concrete floors. • High levels of fire resistance from all ComFlor® slabs with zero soffit protection. • Colorcoat FD® pre-finished steel soffits offer significant extra protection and...

Span parameters Parameters assumed for quick reference span tables Mesh Refer to composite floor decks design information. Spans Measured centre to centre of supports. Deck Standard deck material specification to BS EN 10346. Supporting Beam Width The width of the supporting beam is taken at 152mm, except for deep decks which are assumed to bear on an extended bottom flange 400mm wide. Prop width Assumed to be 100mm. Shear studs One weld through shear stud per trough is assumed to be included for ComFlor® 46, 51+, 60 and 80. Weld through shear studs are not used with ComFlor® 100, 210 or...

ComFlor®  Span parameters Using these reference tables Applied load The total applied loads stated in the Eurocode tables covers an allowable unfactored total load of either 5.00, 7.50 or 10.00kN/m2, which represents three typical cases, as specified in the table below. The total load combination is made up of an imposed live load, ceilings and services, finishes and partition loads. However the dead load of the slab itself has already been taken into account and need not be considered as part of the applied load. The three typical load cases of 5.00, 7.50 or 10.00kN/m2 have been given the...

Classic composite flooring profile, easily transported, simple and efficient ComFlor® 46 was our first composite flooring profile, introduced in the early 1980s and is still popular today for its primary characteristics of being nestable, easily transported, simple and efficient. It is particularly suited for export or difficult access sites, due to the large area of flooring that will fit into a container and because the deck is fast and easy to lay. Nestable The simple trapezoidal shape neatly nests one profile into another, allowing more square metres per bundle. Low transport cost...
