Steel and calcium sulphate raised floors should be compared as complete proposed assemblies. For a South Africa office or technical building, neither core material is automatically the better choice. The useful comparison follows the room schedule, finishes, loads and maintenance requirements.
Start with the intended room use
An office may prioritize accessible floor outlets and a finish that can be reinstated after layout changes. A server room may have more demanding equipment and electrical criteria. Mixed-use buildings should separate these needs in the specification instead of applying one generic description to every room.
Request model-specific information for the steel floor and calcium sulphate floor alternatives. Keep the proposed support height and arrangement visible in the comparison.
Compare the evidence on equal terms
| Issue | Questions for both proposals |
|---|---|
| Loading | Does the report cover the proposed assembly and required loading conditions? |
| Finish | Is the covering approved for the panel and the intended access method? |
| Electrical performance | What test evidence and grounding details apply, if required? |
| Site conditions | What storage, moisture and installation limitations are stated? |
| Maintenance | How are panels lifted, replaced and identified? |
| Documentation | Which drawings, instructions and reports will be supplied? |
Do not infer a universal fire, acoustic or load rating from a core material. If the project specifies one of these properties, request the relevant report and confirm that it applies to the offered configuration. Have the responsible consultant review proposed substitutions.
Check finish and access details together
Ask how the floor covering aligns with the panel grid and how routine service access will be achieved. A finish that is attractive in a sample needs a workable removal and reinstatement method in the installed room. Coordinate thresholds and perimeter cuts before quantities are finalized.
Both alternatives also require protection during storage and construction according to their instructions. A metal facing should not be treated as an unrestricted guarantee against moisture exposure.
Compare complete supply costs
Normalize panel quantities, supports, accessories, spares and delivery scope. Ask for packing dimensions and weights instead of assuming the transport cost from the material name. Identify installation, receiving and local transport costs separately where they are outside the supplier’s offer.
Make a documented selection
Send SunTree Floor the South Africa project application, area, drawings, height, load criteria and finish. Request a comparison quotation showing both system configurations and their exclusions. Select the option supported by the project evidence and accepted by the design team, rather than a generic claim that one core is always superior.
