Spacedek®
Spacedek has a 415mm cover which gives the advantage of easier handling and fixing in long lengths and the 50mm rib profile gives 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 Spacedek® roof sheet profile. In patio, awning and carport situations, translucent sheets must be supported every 1200mm with 3mm strapping attached to steel on both sides, otherwise ponding could occur.
