Stramit CapacityPLUS™ cladding can be supplied in coated and coloured high strength steel, stainless steel and aluminium.

Coated steel product is manufactured from high yield strength G550 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 and galvanised Z450 conform to AS1397.

Stramit has a comprehensive range of colours as standard. Ask at your nearest Stramit location for colour availability.

ADVERSE CONDITIONS:

Stramit CapacityPLUS™ cladding will give excellent durability in almost all locations. It is however important to choose the correct coating for each application environment.

The table below shows the suitability of coating types for different exposure conditions.

Note - The suitability and exposure tables above are guidelines only; conditions will vary from site to site. If in any doubt about the choice of coating for a particular application consult your nearest Stramit office for advice.

COMPATIBILITY:

All building products need to be checked for compatibility with adjacent materials, whether they be part of the current project or pre-existing or planned building elements. These checks need to be for both direct contact between materials, and where water runs from one material to another.The following guidelines generally avoid material incompatibility:

• For ZINCALUME®, COLORBOND® and galvanised roofs avoid copper, lead, green or treated timber, stainless steel and mortar or concrete.
  
  

• In addition galvanised roofs should not receive drainage from aluminium, copper or any inert materials, such as plastics, glass, glazed tiles, COLORBOND® and ZINCALUME®. Contact Stramit for more detailed information.

TESTING:

Stramit has in-house, purpose built, testing equipment used to design, develop and improve products for the Australian market. In addition many Stramit® products are tested or witnessed by independent organisations.

These include:

• Cyclone Testing Station (James Cook University)

• The University of Sydney

• University of Queensland

• University of Technology, Sydney

This ongoing research and development activity ensures that Stramit remains at the forefront of innovation, design and consumer information.

ARCHITECTURAL SPECIFICATION:

This specification may be used to ensure that required performance and functional needs are met:-
