Steel-Deck is an engineer designed and certified, screwed together DIY friendly steel floor framing system.
Made from Stramit long span bearers and joists, using corrosion resistant BlueScope Z350 galvanised steel, as well as Steel-MAX brackets, tek screws and optional steel stumps.
Rectangular in-plane panels are supplied with bearers and joists pre-cut to length and labelled for easy assembly on site and easy connection to existing structures.
Load rated at 3.0 kPa, Steel-Deck is suitable for most domestic and many light commercial applications.
In-plane panels can be joined together to make larger floor frames to the size and shape needed.
Optional Steel-MAX stumps to suit the Steel-deck system, are available.
Steel-MAX modular stumps are supplied as a “Pack”, consisting of a base, telescopically height adjustable top, galvanised post tube and the tek screws needed. These are easy to assemble and install, as well as provide the necessary strength and load support.
The galvanised stump tube is supplied in 8.0m stock lengths only, for cutting to required lengths on site by the builder/installer.
Stumps can be up to 4.0m high.
Make any combination floor needed, with any number of individual panels, of any size up to 12.0m long (bearer direction) x 5.0m wide (joist direction).
Load rated = 3.0 kPa
a live load (approx. 300 kg / m2)
Suitable for most domestic as well as some light commercial decks and mezzanine floor applications.
Joists are spaced at 450mm centres to suit most timber decking and sheeting.
Make any combination floor needed, with any number of individual panels, of any size up to 12.0m long (bearer direction) x 5.0m wide (joist direction)
Joists centres = 450 mm c/c
Live load = 3.0 kPa and 1.8 kN concentrated load, suitable for domestic decks up to and over 1.0 m high.
Dead load = 0.5 kPa
Bearers and joists have been designed to support timber decking or FC sheeting.
Joists must be fixed to end nesting bearers with joist connector brackets supplied to provide web stability and stiffening to both bearer and joists.
Bearers supported on masonry piers or flat surfaces where no web support is provided, must have a minimum of 200 mm bearing along the bearer where the bearer is continuous over that support and 100 mm minimum bearing at the end where direct bearing only occurs.
This is not a requirement where bearers are supported on Steel-MAX stumps, which provide sufficient web support in addition to direct bearing.
