Connection & Installation Instructions
All steel fixings can be replaced with welded connections.
Check with your/our Engineer to determine the appropriate design loads for your floor.
Installation Instructions
- Extra joists should be added under non load bearing, internal partition walls which are within 80% of their maximum span.
- Add extra joists at half spacing under spa baths or water beds.
- For all load bearing internal walls or point loads, please consult with your Hopleys representative.
- Do not notch top or bottom chords or remove webs. If a web needs to be removed, please consult with your Hopleys representative.
- We highly recommend screwing the sheets to the joists using a QuikDrive™ PRO250 Auto-Feed Screw Driving System, which can be purchased or hired from your Hopleys representative. You will require approximately 29 screws per 3600mm x 900mm sheet.
- Alternatively the floor sheets can be nailed down using hardened twist nails available from various manufacturers such as Senco, Duo-Fast, Bostitch and Paslode.
- Ensure that once the floor has been fixed that any nails protruding through and touching the webs are bent away a few millimetres using pliers.

An approved construction grade adhesive should be used to bond the sheet flooring to the joists. Approximately 2 tubes of 850ml will be required per 10 - 3600mm x 900mm sheets.
Spacing and Span
"Spacing" is the centre to centre distance between structural members and is assumed to be 450mm unless noted otherwise.
"Span" is the face to face distance between points of support for the structural members.
"Single Span" is the span of a member supported at both ends with no intermediate support. This is also known as "simply supported".
"Continuous Span" is when a member has support at both ends and also at one or more evenly spaced points between the ends.
