4. Based upon concrete densities at wet stage: normal weight concrete 2400 kg/m3,
lightweight concrete 1900 kg/m3.
5. Concrete volumes: Figures shown in the tables are nominal values based on constant slab
thickness. As with all steel decks, an allowance should be made for the deflected form
of the soffit when ordering concrete and, as guidance, we suggest that the estimated
volume of concrete equates to: Overall slab depth - 8mm for voids + span/250.
6. A span to depth ratio limit of 35:1 for normal weight concrete and 30:1 for light weight
concrete is generally used. Where isolated single spans occur, these ratios are reduced
to 30:1 and 25:1 respectively.
7. Maximum deflections are limited to span/130 after taking account of ponding.
8. Construction stage design includes an allowance of 1.5kN/m2 for construction loading.
9. Composite slabs are designed as simply supported irrespective of the deck support
configuration. A minimum crack control and distribution mesh is required over the
supports in accordance with clauses 6.7, 6.8 and 6.9 of BS5950: Part 4.
10. S280 decking is manufactured from material meeting the specifications:
BS EN 10147-S280GD+Z275-N-A-C, ie.yield strength = 280 N/mm 2
S350 decking is manufactured from material meeting the specification:
BS EN 10147-S350GD+Z275-N-A-C, i.e. yield strength = 350 N/mm 2
Note: S280 & S350 yield strengths are referred to in British Standards and this terminology
replaces superseded references Z28 & Z35.

Some technical
benefits of Holorib:
Best concrete compression block
for flexural resistance
Deep concrete section/high steel
Tables are applicable for any construction where the mesh may act in tension
over a supporting beam or wall (negative bending). This includes end bay conditions
i.e. the concrete slab is continuous over more than one span.
2.
Loads shown are unfactored working loads and should include all imposed
live and dead loads, excluding only the self-weight of the slab.

6.
For conditions outside the scope of the simplified tables, including all isolated
spans, consult SCI publication 56 (2nd edition) or RLSDs Deckspan software.

LIGHTWEIGHT CONCRETE
Permanent shuttering
Can be used with lightweight or dense concrete
Up to four hours fire resistance with exposed soffit can be designed
Composite construction reduces steelwork frame weight
Lower dead load reduces frame and foundation loading
Stiffens supporting frame if steelwork used
Cover for following trades
Provides a safe working platform
Easily cut and fitted to awkward shapes
Minimal site storage requirements
Separate panels can be manhandled into restricted access situations
Provides the Tensile reinforcement
Needs no (or minimal) propping
Shear studs can be site welded through-deck
for composite construction
Speeds construction programme essential in
fast-tracking
Ceilings and services can be easily suspended
using standard fixings
