Standing seam metal roofing system

LokFold is a high-quality, fully supported, metal roofing and cladding system available in a variety of quality metal finishes including pre-painted and mill finish aluminum, copper, zinc and stainless steel.

The LokFold system provides traditional standing seams or batten rolls on pitched roofs or walls. The system is based on metal trays which, can be formed in the factory or on site, and which are fully supported by the deck to which they are attached, providing a ‘traditional’ and aesthetically pleasing roof construction that is also extremely cost-effective.

Attachment to the deck is made with a combination of fixed and sliding cleats which allow for thermal movement in the length of the tray. The cleats are mechanically folded into the standing seams either by hand or using a portable folding machine.

Standard metals

  • LokFold is available in a variety of metals and finishes:
  • Aluminum
  • MicroZink
  • Stainless Steel
  • Copper
  • Zinc

Reverse coating of zinc

It is traditional to use an underlay to separate zinc from the supporting layer unless the system is fully insulated. As an alternative, zinc is offered with a plastic coating on the reverse side.

Product availability

LokFold is available in a variety of formats from the plain coil to the fully installed system.


For installers who have their own roll forming capacity, we can provide a coil for this purpose. As major traders in metal products, our buying capacity means that we can provide extremely cost-effective terms, particularly on aluminum and our own MicroZinc products.
