Scope of Use
  • Dimond Structural Flooring Systems use a roll-formed profiled galvanised steel sheet as a component in reinforced concrete floor systems
  • The steel decking sheet provides both permanent formwork and positive tensile reinforcement in one way reinforced composite floor slab construction over concrete block walls, poured concrete beams, steel beams or timber beams, subject to the environmental limitations referenced to the appropriate grade of the material selected
  • It is critical to product performance that the loads applied, spans, formwork material thickness and overall composite floor slab thickness are designed within the appropriate Limit State Loads and limitations published in the Flooring Systems Design Manual
  • Before commencing a project using a Dimond Structural Flooring System, the user must refer to the information within this manual and all sections as appropriate, ensuring relevant information is available to the end-user. Failure to observe this information may result in a significant reduction in product performance
  • Dimond Structural accepts no liability whatsoever for products which are used otherwise than in accordance with these recommendations
Limitations on Use

The use of galvanised steel decking sheet should be avoided:

  • In areas where high concentrations of chemicals are combined with a high humidity, where the system remains wet for long periods of time, causing rapid consumption of the galvanised zinc coating and eventual red rusting of the base metal
  • Where the galvanised surface is being exposed to continuous moisture, without a chance for the surface to dry out for example, where the composite floor slab covers a water tank
  • In or near marine environments, where the prevailing wind carries marine salts which deposit on the steel decking, causing rapid consumption of the galvanised zinc coating and eventual red rusting of the base metal.
  • In areas surrounding chemical or industrial storage buildings where any chemical attack may lessen the life of the structure or wind-driven chemical fumes may attack the galvanised coating
  • When in contact with or laid directly on ground
  • When in contact with timber and especially treated timber such as CCA (copper chrome arsenic) without the use of an isolating material such as DPC between the timber and galvanised steel decking sheet
  • When used in sub-floor areas with less than 450mm ground clearance
  • When used in sub-floor areas where ventilation does not comply with NZS 3604 Clause 6.14

Chemical admixtures may only be used with Dimond Structural Flooring Systems if they are compatible with galvanised steel
