PRODUCT DESCRIPTION & FEATURES
Widedek is an angular trapezoidal fluted sheet and is similar in appearance to IBR roof sheeting, the difference being the cover width of the roof sheet, and the depth of the flutes. Widedek sheeting has a cover width of 760mm and the depth of the flutes on Widedek is 29mm. The Widedek profile has a bigger cover width than IBR, resulting in a saving on sheeting.
Using this type of sheeting has certain cost saving advantages.
- The Widedek profile has a better cover width than IBR, resulting in a saving of ±10% on sheeting purchased.
- To achieve the same coverage less sheets are required to be erected, thus saving on time and labour.
- The advantage of using Widedek in place of a sinusoidal corrugated profile is its strength. The spanning capacity of Widedek is greater than the corrugated profile thus requiring less purlin also resulting in a further cost saving
- Widedek can be factory cranked, curved and bullnosed to a wide range of radii.
