Product Description and Features

KLIP-LOK® 406 is a strong, durable and versatile long length roof or wall cladding. The concealed fastening method enables its use on many applications from low pitched roofs to vertical or horizontal ribbed walling.

  • Fixing clips effectively secure KLIP-LOK® 406 to supports without puncturing the sheet
  • No exposed fasteners means clean and smooth lines


  • KLIP-LOK® 406 is only available upon enquiry in some states. Please consult the availability table below for further details
  • Minimum recommended roof pitch is 1 degree (1 in 50)

Span Table

The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.0-1992 and AS4040.1-1992.

Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance) and assessment of ease of installation.

Can KLIP-LOK 700 HI-STRENGTH® be side-lapped with KLIP-LOK® 406?

No. KLIP-LOK 700 HI-STRENGTH® has a rib shape and clip design different to the traditional KLIP-LOK® 406.

Can KLIP-LOK® 406 be unclipped?

It is not recommended to unclip KLIP-LOK® 406 once the cladding is installed. Unclipping can damage the clips, cladding or metallic coating on the cladding. It is difficult to assess how KLIP-LOK® 406 will perform after such damage.

What is cladding and how does it relate to roofing and walling?

Cladding is a collective term for any sheeting that covers a building, whether it be on the roof of the building, or on the walls. Roof cladding is made from thicker steel and is rolled to a profile capable of supporting roof traffic*. In most cases, these roof claddings can also be used for walling as well. Wall cladding is made from thinner steel, rolled to a less rigid profile. They are generally not capable of supporting roof traffic, prohibiting their use as roofing.

*Some roofing is designed to be non-trafficable. Please consult the span and capacity tables of the cladding for further details.
