Space Spanning Strength

Patio cladding embued with strength and a unique snap together action

Spacedek has a 550mm cover which has the advantage of being easier to handle and fix in long lengths. The 50mm rib profile provides greater strength and spanning abilities which reduces the number of purlins and girts required.

Complying with Australian Standards, Spacedek simply snaps together providing a strong locking action. It features a 4.4m roof span when used in accordance with Stratco fixing recommendations.

Spacedek is rolled to lengths that suit your specific requirements. Minimum lengths available are 1.2 metres. Sheeting longer than 10 metres requires special transport, handling facilities and on-site labour to assist in unloading sheets.

Translucent Sheeting

Translucent sheets are also available to match the Spacedek roof sheet profile. In patio, awning and carport applications, translucent sheets must be supported every 1200mm with 3mm strapping attached to steel on both sides, otherwise ponding could occur.
