Handling and storage To ensure delivery of product undamaged, suitable arrangements should be made for unloading. When lifting product by crane, care must be taken to ensure the load is spread evenly. If a crane is not available, sufficient labour must be supplied to assist with manual unloading.

Site Storage Sheets should be laid as soon as possible after delivery. If site storage is necessary, packs should be kept dry and above ground. If sheets do become wet, separate them, wipe and place in the open to dry. Installation

Good Practice Stramit recommends that good trade practice be followed when using these products, such as found in CCAA/Standards Australia handbook HB67 ‘Concrete practice on building sites’.

Supports It is imperative that permanent supports (steel or concrete beams, or walls) be stable and of adequate strength to withstand loadings prior to the placement of the decking. Ensure that the end bearing width (min 50mm) and internal bearing width (min 100mm) nominated by the engineer is achieved on site. In the case of masonry walls, a damp-course strip should be installed between the masonry and the decking.

Temporary Propping, where required, must provide continuous transverse (across the sheet) support at the prescribed spacings. The prop bearer width must be no less than 100mm, unless established by calculation. Continuous support is generally provided by substantial timber or steel beams supported by vertical props. If the deck soffit is to be left exposed, it is recommended that a piece of caneite or similar be placed between the bearer and the deck. All propping should meet the requirements of AS3610, including bracing. Prop bearers should not be placed higher than the permanent end support.

Sheet Placement Stramit Condeck HP® decking is easily placed by hinging the overlap edge of one sheet over the underlap edge of the previous sheet. If the decking is used as a platform for laying subsequent sheets, designated propping must be positioned first.

Walking On The Deck Take care when walking on Stramit Condeck HP® decking, particularly if the surface has become wet. Wear suitable rubber-soled footwear at all times. Also note that, when first delivered, there may be traces of rolling oil present. It is possible to step either in the pans or on the ribs of Stramit Condeck HP® decking but when walking use only the pans. Avoid walking on the edge sheet, or on rib ends.

Cutting Stramit Condeck HP® decking is supplied cut to length. Generally, cutting is only required around projections and cut-outs. Use a power saw fitted with an abrasive disc or metal cutting blade. Cuts should be started with the decking laid upside down (ribs down). If necessary, turn the sheet and complete the cutting of the ribs. This method provides the neatest finish and minimises the risk of burred edges being exposed on the finished slab.

Fixing Once decking panels are laid they should immediately be secured against possible wind uplift. Typically use one fixing per pan at end supports, and one fixing every third pan at permanent internal supports. Self-drilling and tapping screws or 4.5mm powder actuated drive pins are commonly used. These fixings should be adjacent to the decking ribs. In exposed conditions additional fixing may be required. Shear studs, if used, attached immediately after decking placement, or puddle welds, will provide wind uplift resistance.

Side-Lap Fasteners Side-lap fastening is only required if stacked construction materials are to be laid in the decking pans. Where required, side-lap fasteners should be at least No.10x16 self-drilling and tapping screws. These should be fixed through the trough in the rib tops, and positioned at mid span on every rib.
