Single and Double-lock Standing Seam

STANDING SEAM FOR ROOFING, CLADDING & SOFFIT

Standing seam system is a traditional flat-tray roofing and cladding system with a raised 25mm seam. All fixings are concealed using stainless steel clips that allow for expansion and contraction in the cladding panels. The pan widths are customisable using our state of the art manufacturing equipment to the millimetre allowing total control over your designs. It reflects the individual concerns for both light and shadow and produces designs that have a modern yet historical perspective that offers a traditional, refined look, with maximum flexibility. Standing Seam is capable of achieving intricate designs that other systems cannot. It is suitable for both roof (double-lock) and wall cladding (single-lock) which makes it ideal for dramatic residential and commercial architectural roofs and facades.

DOUBLE-LOCK STANDING SEAM

The double-lock Standing Seam is a traditional system that has been used historically throughout Europe and America for many years. Seams can also be mitred into cladding pans for a seamless design. Many modern building designs now incorporate the double lock standing seam system. Minimum 3 degree pitch required for roofing.

SINGLE-LOCK STANDING SEAM

The single-lock Standing Seam can be installed vertically, horizontally or diagonally in wall cladding applications. Panels can be curved both horizontally and vertically. Seams can also be mitred into roofing pans for a seamless, flashing-less design. Many modern building designs now incorporate the single lock standing seam system.

FEATURES & BENEFITS

Incredible flexibility and versatility with standing seam metal roofing and cladding. Unlimited design options with panel widths changeable to suit wall and roof width, windows and skylight penetrations; tapered, curved, convex and concave; cross joints to create specific lines or continuous cladding for long panel applications.

Fully waterproof with all details and panel connections made to leverage inherent material waterproofing.

Economical due to minimal wastage of materials.

Ability to connect with continuous seam to between single-lock standing seam wall cladding and double-lock standing seam roofing.

OUR EXPERTISE

We work closely with architects during the design stages to share our expertise on installation and technical details. From traditional to contemporary applications, our aluminium, zinc and copper roofing and cladding solutions are specified based on their durable, sustainable and virtually maintenance-free nature that need to withstand the elements and protect those within. Being corrosion resistant, non-combustible, architecturally appealing, their outstanding list of benefits just can’t be beaten.

VMZINC

Composed of very high quality zinc (at least 99% pure) alloyed with copper and titanium to make it harder and stronger, increasing both mechanical and creep resistance.

Lifespan of 50–80 years, depending on exact location.

Continues to develop a natural protective layer (or patina) as it ages, self-repairing any marks and scratches throughout its lifetime.

COPPER

Lifespan of 70­­–100 years, depending on exact location.
As a result of surface oxidisation caused by weathering, copper forms a protective barrier (patina) that resists further corrosion and extends its life.
This results in ongoing colour changes depending on the environment – from blue-green to nut-brown.

ALUMINIUM

Superior quality aluminium, produced In Europe and available for use in all our panel systems.
Lifespan of 40–60 years, depending on exact location.
Pre-painted using a PVDF paint system, using at least two layers to produce a minimum paint thickness of 27 microns.
Can be used in areas without direct rainfall with no corroding or discolouring.

COLORBOND

Manufactured in Australia to Australian Standards (AS1397 and AS/NZS 2728) and tested in some of the harshest Australian conditions over the last 50 years, genuine COLORBOND® steel is far more than just ‘paint on steel’.

The COLORBOND® steel range has been developed to give great design versatility and to suit a wide range of environments. And the new COLORBOND® steel Matt range of colours create a softer, more subtle look that is both understated and contemporary.

The steel base is manufactured to meet relevant Australian Standards, ensuring strict adherence to the required grade and strength.

CORTEN

Often called “weathering steel”, Corten steel panels form a stable rust-like appearance if exposed to the weather for several years.
This protective surface layer, or patina, is produced by Corten’s metal panel chemical composition and produces anti-corrosive properties superior to many other structural steels.

ROOF OR WALL STRUCTURE
Must consist of continuous roof or wall top hats (rafters or studs) at max 600mm spacing. Minimum 3 degree pitch required for roofing.
SUBSTRATE
For roofing 18mm plywood or spandek sheets when non-combustible buildup is required. For cladding 15mm plywood or trimdek/spandek sheets when non-combustible buildup is required.
UNDERLAY
Breathable waterproofing membrane for both roofing and cladding
FIXINGS
Standing seam clips installed at maximum 300mm distance. Clips to be min 0.4mm stainless steel. Fixed and sliding clips to be used to allow for expansion and contraction of panels.
VENTILATION
40mm continuous air gap must be beneath the plywood substrate for ventilation for all VMZINC installations. It is recommended to be used on all other metals when using plywood substrate.

Metal cladding/roofing and especially lengthy flat-span sheet-metal panels often will exhibit waviness, commonly referred to as “oil-canning.” The degree of oil-canning and the appearance of the panels will vary depending on factors such as the length and colour of the panels, alloy, gauge, substrate condition and exposure to sunlight. Oil-canning pertains to aesthetics and not the performance of the panels and is not controlled by the contractor. The type of metal roofing panels specified can affect the degree of oil-canning. Roofing Group is not responsible for oil-canning or aesthetics. Oil-canning shall not be grounds to withhold payment or reject panels of the type specified.
