General Design Criteria


Recommended Uses
The recommended uses of Nutec Flat Sheets under normal conditions are tabulated for easy reference in Table 2.

Mechanical and Physical Properties
Details on the mechanical and physical properties of Nutec Flat Sheets are scheduled at the end of this brochure.

Painting, Finishes and Coatings
The sheets are best painted with a pure acrylic PVA paint. Where it is intended to use oil or alkyd paints it is essential to prime the sheet with an alkali-resistant sealer. In this instance both faces of the product should be sealed.

Exposed and Windy Conditions
The information presented in this catalogue is a guide only for normal wind-loading conditions.

Please consult an Engineer or Architect for advice on specific fixing and framing recommendations for structures in normal-or high-wind areas.

Substructure Guidelines
The design of structural supports requires professional expertise and should be executed by structural engineers.

  • For specific fixing and framing recommendations where the sheets are to be used for applications such as floors, shelving and permanent shuttering, please consult an engineer or architect for details.
  • If used for flooring, and covered with ceramic tiles or other inflexible material, expansion joints must be provided. Please refer to an engineer for details.

When using Nutec Flat Sheets to form a double skin wall in a prefabricated steel or timber framed structure, the cavity (if not fully filled) between the two skins should be ventilated. In these structures, especially in humid conditions, foil is often installed as a moisture barrier and as an insulator. Ventilating the cavity will permit the evaporation of any condensation which may collect.

Site Service
Site service personnel are available on request to assist with recommended storage, handling and erection of the Company’s products before and during installation.
