Steel – Panel 850 Ceiling and Soffit Cladding

Steeline Steel Panel is a modern, stylish, high strength, lightweight sheet cladding material.
It is an ideal product not only for walls, but also to use on ceiling and soffit linings.

Made from high tensile steel, the profile has been engineered to give the highest strength and rigidity possible, whilst using the least amount of material.
Manufactured locally using quality Colorbond® or Zincalume® steel, Steeline Steel Panel is strong and long lasting.

The sheets of Steeline Steel Panel overlap each other, and are fixed progressively along the building in the opposite direction to the prevailing weather. This gives complete weather protection, and a fast and efficient method of installing the roof. Each sheet consists of an “over” rib and an “under” rib and when put together they form an effective seal, preventing water entry


Steel-panel can be bent along the sheet at minimum bend radius of 3mm, however it is not recommended to bend it across the sheet.

Laying (Ribs Vertical)

Start at the end of the wall which is away from the prevailing weather. The over-edge should be as shown:

Laying (Ribs Horizontal)

The edge laps must face downwards with the over edge (double side rib) on top as shown. If end laps are necessary on long runs, allow 75mm per lap. End laps should be sealed with suitable sealant.


Recommended fasteners
Steel framing (up to 5mm thick):
No. 10×16 wafer head self drilling tek screws or blind rivets.

Timber framing:
No. 8×25 pan head type 17 self drilling wood screw.

Side lap fasteners
Use No. 8×12 hex head type S self drilling screw with neo washer or blind rivets.

When using the overlapping rib jointing method, these are added at the midspans of the sheets for support spacings over 800mm. When using the overlapping edge method, side lap fasteners are required at 300mm centres maximum.

Location of fasteners

At the ends of sheets and at end laps, fasteners are to be located at every second valley. At intermediate supports a fastener is to be located either at the side lap or adjacent to it, with 4 fasteners used equal distant across the sheet. Note: In some applications e.g. Interior applications the number of fasteners may be reduced by up to 50%.


When unloading bundles of sheeting with a crane always use a spreader bar and fabric slings to prevent damage. When manually handling sheets use clean dry gloves and do not drag sheets over each other. Storage of sheets should be above ground and under cover.

Do not locate fasteners less than 25mm from the end of sheets. Do not use punches to form holes for fasteners. Holes are to be drilled or self drilling fasteners are to be used.


Steeline Steel Panel can be cut in the factory to any length specified by the customer. Tolerance on the length is +0mm-5mm.
