General Information close-medium-white

Many internal applications for Stramit Perforated or Acoustic Sheets will be relatively benign. In applications of high humidity or corrosive environments, contact your local Stramit office to discuss the optimum material choice.

All building products need to be checked for compatibility with adjacent materials. These checks need to be for both direct contact between materials, and where water runs from one material to another.

Stramit products should be handled with care at all times to preserve the product capabilities and quality of the finish.

Packs should always be kept dry and stored above ground level while on site. If the products become wet, they should be separated, wiped and placed in the open to promote drying.

Stramit Premier 300™ Perforated Panels are supplied cut to length. When designing or transporting long products ensure the length is within the limit of the local Transport Authority regulations.

Manufacturing tolerance on length of product supplied is +0, -15mm.

All Stramit panels are made from steel that confirms with AS 1397.

Technical Information close-medium-white

The internal wall/ceiling shall be Stramit® Acoustic Panel System in the Premier 300™ profile. Material shall be protected steel sheet to Australian Standard AS1397 with a minimum yield stress of 300MPa (Grade 300) and an ZA150 zinc-aluminium coating (or an AM100 zinc-aluminium-magnesium coating) with an off-white, oven baked paint film.

The sheeting shall be fixed to the structure in accordance with the manufacturer's instructions.

All sheeting shall be fixed in a professional manner, leaving the job clean and with minor blemishes touched up with paint supplied by the manufacturer. All insulation/absorbing materials shall match the Stramit specification contained in the Stramit Acoustic Panel System Technical Manual.

Use one fastener per panel per support.

All fasteners should conform to AS3566 – Class 3 and be compatible with the cladding material used.

For steel:

  • 10 x 16mm wafer head self drilling, self tapping screws.

For timber:

  • 10 x 25mm type wafer head self drilling Type 17 screws. Add 10mm to screw length for softwood applications. Alternatively use 4mm aluminium pop rivets or 40mm flat head galvanised clouts for steel or timber respectively.

For wall areas likely to be subject to human impact, sheeting spans should be reduced. Impact loads will vary considerably and these are not prescribed in Australian Standards.

A maximum span of 900mm is suggested for such areas, but this should be adjusted dependent upon the exposure and importance of the application.

Stramit Premier 300™ Perforated Panels are manufactured from G300 colour coated steel or zinc-aluminium alloy coated steel. In some locations galvanised and severe environment colour coated steel may be available by arrangement.

Colour coated steels are in accordance with AS2728 – Category 3 and, for the substrate, with AS1397. Zinc-aluminium alloy coated AZ150, aluminium-zinc-magnesium alloy coated AM100/AM125 and galvanised Z450 conform to AS1397. 

Stramit standard perforations cover approximately 11% of the cladding surface. Holes are 2.4mm in diameter and are pitched symmetrically across the sheet.

This layout gives the best balance between appearance, ease of installation cladding performance and noise reduction.

Contact our technical services consultants if you require a different hole pattern.

Stramit Premier 300™ Perforated Panels may be subjected to loads from impact or limited by acceptable deflection. Maximum recommended spans in millimetres for each profile are shown in the table below. For most expected applications, the panels will not be subject to wind  loading.

However if either should be applicable, please refer to the relevant Stramit Technical Product Manual for these capacities.

Installation Information close-medium-white

Stramit's cladding can be easily cut, where required, using a power saw with a steel cutting blade or a power nibbler and, for localised cutting, tin snips. Avoid the use of abrasive discs as these can cause burred edges and coating damage. Please dispose of any off-cuts carefully.


Consideration should be given to handling and installation issues as part of site induction safety procedures. Specific consideration should be given to pack handling, avoidance of cuts, trips, slips and falls, long section handling, particularly in windy conditions, section cutting procedures and surface temperature on sunny days.

Wear safety glasses with side shields when cutting or trimming product. Cut resistant or leather gloves should be worn when handling product. Foot protection should be warn when handling and transporting product.

Stramit recommends installers follow the installation code for metal roofing and wall cladding as outlined in the Standard Australia Handbook – HB39. 

Maintenance Information close-medium-white

Should it be necessary to wash Stramit Perforated or Acoustic Sheets, use the following procedure:

  • Wash the surface with a mild solution of pure soap or non-abrasive, non-toxic, kitchen detergent in warm water using a sponge, soft cloth or a soft bristle nylon brush.
  • Thoroughly rinse with clean water immediately after use.
  • Never use abrasive or solvent type cleaners, such as turps, petrol, thinners or kerosene, on COLORBOND® steel.
