Stratco 900 is a metal trapezoidal roof and wall cladding with 900mm cover and 37mm rib height that is suitable for a minimum roof pitch of three degrees. This allows for long spans and has excellent water carrying ability.
Stratco 900 has a 'square corrugated' form that has the looks and versatility to allow it to blend easily with any building style. Its strong seven rib design lends itself for use on roofing, wall cladding and fencing. Stratco 900 is ideal for architects and builders who are trying to achieve a different look, with maximum serviceability.

Packs of Stratco 900 sheeting should always be kept dry and stored above ground level on site. If the sheets have become wet, they should be separated, wiped and placed in the open to dry.
Stratco 900 sheets should be laid lapping to sit neatly on the preceding roof sheet.
Cut pre-painted steel material by shear only — use nibblers or hand shears. Friction blades and high-speed saw blades must not be used on metal cladding.
Black lead pencils must never be used for marking aluminium/zinc, and unpainted or pre-painted steel products. Use a pencil of any colour other than black, a marker pen, or crayon.

All roofing and cladding products are subject to the cumulative effects of weather, dust and other deposits so the performance and durability of Stratco 900 roofing and wall cladding over time depends on its correct maintenance. For roofing, normal rain washing will remove most accumulated atmospheric contaminants from the top side of roofs.
Areas that do not receive adequate rain washing (known as unwashed areas) require more extensive manual washing.
Roofing and cladding products should be manually washed by either water and a sponge or a soft nylon-bristled brush or by water blasting at pressures of no more than 20MPa. Never use abrasive or solvent based cleaners such as turps, petrol or kerosene.
