ATS300 is a cold formed section manufactured from Australian steel.

It is an efficient and durable permanent metal formwork product, which is available in 0.60, 0.75, 0.90 or 1.00 mm Base Metal Thickness (BMT).

The coating class Z350 (350g/m2 of zinc) provides good resistance against corrosion.

ATS Steel Deck

Property Advantages

300mm Strip Width > Easy transport & handling > Less off-cut and waste

Interlocking Ribs > Quick installation > Reduced Deflection

Rolled Formed from G550 Steel > High tensile strength and good bonding with concrete > Reduce steel reinforcement usage

Flat Soffit Finish > Visually pleasing > Easy to clean and paint > Easy bolting to Soffit

Permanent Formwork > Minimal propping > No stripping of formwork required

Local Production and Distribution > Supporting Local Industry > Local design support and customer service

ProppingTemporary propping shall be provided according to ATS STEEL DECK formwork span table or instructions from a qualified structural engineer to avoid excessive deflection and prevent failure of formwork.

A minimum bearing width of 50mm for edge supports and 100mm for intermediate supports and temporary props must be provided unless approved by a qualified structural engineer.

All propping must be continuous across the width of ATS STEEL DECK formwork. The design, documentation, erection and removal of propping must comply with AS3610.

Fastening

ATS Steel Deck

Sheet PlacementThe edge ribs of ATS STEEL DECK sheets are designed to be interlocked. It is recommended to position a new sheet at an angle to a laid sheet, then slowly rotating it till the ribs are locked in place.

The sheets shall be fixed to provide resistance against uplift forces and lateral movement.

Appropriate fixing methods may be chosen from: welds, nails or screws. Headed studs welded through sheets to structural steel in composite beam design are also considered to have adequate resistance against uplift.

However, some temporary fixing shall be provided to hold down the deck prior to stud welding. Fixing of the sheets should be provided adjacent to every rib over each support.

Edge FormEdge forms are lipless C-sections rolled from light-gauge steel.

It can be easily trimmed, bent, spliced and fastened to achieve the ideal edge finish. The bottom flange of the C-section can be fastened to structural steel or the underside of ATS STEEL DECK sheeting. The top flange shall be braced using steel straps at maximum of 600mm centres.
