Designed to lock together, each Topdek 700 sheet has a male and a female edge that forms a strong locking action when joined together. The anti-capillary shape of the female rib means water is stopped from entering through the side-laps. The sheets lock into the specially designed Topdek 700 clips. The clips are fastened to the purlins with hex head screws (table 8.0) through the holes provided. Although the clips join the roof deck to the purlins, they still allow for expansion and contraction, which is important for long length roofing.

Custom made for your project

For lengths over 1.2 metres, Topdek 700 can be rolled to the length you require, provided the appropriate transport and handling can be arranged. For lengths longer than ten metres, contact your nearest Stratco for advice on handling and transport. Stratco offer a complete range of flashings and accessories for use with Topdek 700, and can provide professional advice on specific flashings.

Ordering

Sheets are available custom cut, allowing you to minimise waste, and enhance your design options. Topdek 700 is available in un-painted zinc/alum, and in an attractive range of factory pre-painted colours. Subject to the delivery location, quantity and material availability, delivery is usually within 48 hours, or at an agreed time that suits your building schedule. Unless advised differently, a one tonne maximum is usually applied to larger packs. Arrangements for unloading the truck are the responsibility of the customer, and should be arranged before ordering. When unloading you must ensure the load is adequately spread. Use spreaders and slings to prevent damage. If packs are to be loaded directly above structural members, they must be of sufficient strength, such as over portal frames, or braced roof trusses.

Maintenance Requirements

The performance of Topdek 700 over time depends on its correct application and maintenance. Maintenance should be performed as often as is required to remove any dirt, salt and pollutants. Where used in severely corrosive environments, cleaning should be performed more often. It is important that screws have the same life expectancy as the cladding you have specified.

Packs of Topdek 700 should always be kept dry and stored above ground level while on site. If the sheets have become wet, they should be separated, wiped and placed in the open to dry.
