Values in shaded cells denotes spans that exceed foot traffic limitations. Internal spans should have both end spans 20% shorter than tabulated values. The maximum permissible free edge overhang is 150mm from the screw line.

7 The maximum permissible stiffened edge overhang is 300mm from the screw line. Sheeting span can be limited by maximum batten spacing when using CYCLONIC steel battens. It is essential that the relevant deemed to comply information (for NT) for the batten product is used in conjunction with these TO TABLEST hese tables have been prepared by LCJ Engineers Pty Ltd.
