STRUCTURAL DECKING Designer’s guide Steeldeck production at our plant in Zwevezele, Belgium. The Joris Ide Group is one of the largest independent European producers of insulated and non-insulated cladding systems and components. Its product range varies from single skin profiles to continuous produced PIR and Rockwool composite panels, purlins, flashings, rainscreen cladding and structural metal decking. Perforated decks for acoustic purposes. Metal decking is used in commercial and industrial applications for a built-up flat or low pitched roof. In combination with site-applied insulation...

Membrane Roof System Membrane Roof Systems with structural decks are often used for very low pitched or flat roofs combining long spans. The classic built-up exists out of JI Structural Deck in steel or aluminium with the option for perforation to improve acoustic absorption. Essential for this warm roof construction a vapour barrier is applied between the PIR, mineral wool or glass fibre insulation to be finished with a waterproof membrane . Standing Seam System Standing Seam Systems are used for the combination of their secret fixation, ability for low pitched roofs and curved roofs. The...

Perforation patterns Perforation in the decks are available depending on the type of deck and the location of the perforation (web, pan or full) to improve the acoustic absorption performance of the built-up system. Each Joris Ide decking production site has a high-performance perforating line to offer what is required for the project. Joris Ide Belgium offers the following perforation patterns: 6 Joris Ide Deutschland offers the following perforation patterns: 8

Mounting instructions Storage and handling The packs need to be unloaded at site in a controlled and careful way not to damage the goods and according to the health and safety regulations at force. Once unloaded, the packs need to be safely stored inside a cool and dry building and under a small slope in order to have no storage stain (white rust). Fixing recommendations The table below gives an overview of the recommended fixations. These recommendations are based upon good practice and do not take away the responsibility of the designer and the installer to check the limits of the...

Diaphragm What is a diaphragm action? The roof sheeting in a rectangular building under horizontal loads behaves like the web of a deep plate girder spanning between vertical planes of support. In this plate girder the longitudinal edge members behave as flanges, carrying the axial tension and compression. The girder helps resist horizontal loads. In a pitched roof building the roof slopes help to resist both horizontal and vertical loads. Shear field in sheeting Flange forces in edge members Sheeting Roof sheeting acts as a deep plate girder carrying load back to stiffened gables A shear...

Extended end laps When decks of long length impact the cost of transportation or create an inefficiency for handling or installing on-site, the solution of extended overlaps can be applied. Extended overlaps between two single span decks create a double span condition which enhances the mechanical performance. Therefore the below conditions need to be respected: Extended overlaps can only be used for decks manufactured out of steel. For perforated variances and aluminium decks please consult the Joris Ide Technical Support Team. The end lap must extend by 10% of the span from the opposite...
