ComFlor 210

From the Panels and profiles deep composite profile range
The original SlimFlor long span steel deck, ComFlor 210 has the capability to span up to 6 metres in unpropped construction. Suitable for use in Corus Slimdek® construction, which offers minimal structural depth, fast construction and many other benefits.

• With cross and longitudinal stiffeners, ComFlor 210 is structurally efficient and offers excellent composite action with the concrete
• Simple single bar reinforcement in each trough, combined with anti-crack mesh near the top of the concrete slab gives the composite slab superb structural strength and fire properties
• The nestable profile shape reduces transport and handling costs
• Up to two hours fire rating with unprotected soffit

Volume and weight table notes

1. Deck and beam deflection (i.e. ponding is not allowed for in the table).
2. Deck and mesh weight is not included in the weight of concrete figures.
3. Density of concrete is taken as:
   •  Normal weight (wet) 2400 kg/m²
   •  Normal weight (dry) 2350 kg/m²
   •  Lightweight (wet) 1900 kg/m²
   •  Lightweight (dry) 1800 kg/m

Design notes

Deck material
Zinc coated steel to BS EN 10147:1992, Fe E 350G, Z275, with a guaranteed minimum yield stress of 350 N/mm². Minimum zinc coating mass is 275 g/m² total including both sides.

Quick reference tables
The quick reference load/span and fire design tables, on the following 2 pages are intended as a guide for initial design, based on the parameters stated below the tables.

Anti-crack mesh
BS 5950: Part 4 currently recommends that anti-crack mesh should comprise 0.1% of slab area. The Eurocode 4 recommendation is that anti-crack mesh should comprise 0.2% of slab area for unpropped spans and 0.4% of slab area for propped spans. Panels and Profiles in conjunction with The Steel Construction Institute, has agreed to modify the requirement with regard to anti-crack mesh, to comply with the Eurocode 4 recommendations. Accordingly, the mesh shown in the quick reference tables complies with EC4 and the design program defaults to these values. Where EC4 mesh rules are used, the mesh may be reduced midspan. The reduced British Standard mesh values may still be used by overriding this default in the design program. Mesh top cover must be a minimum of 15 mm, and a maximum of 30 mm. Mesh laps are to be 300 mm for A142 mesh and 400 mm for A193, A252 & A393 mesh.

Fire
For details of the performance of composite slabs under a fire condition with nominal anti-crack mesh, please refer to the quick reference fire load tables.
