Order COLORBOND® Steel Receiver Channels for Patio and Roofing Support

Receiver channels are an essential structural component when installing insulated patio roofing systems like SolarSpan®. Made from high-quality COLORBOND® steel, these channels provide strong perimeter support, helping to secure panels in place and ensure a clean finish along the edges of your patio or verandah.

Perfect for use in both residential and commercial outdoor builds, receiver channels are designed to resist corrosion, maintain structural integrity over time, and match seamlessly with the rest of your COLORBOND® patio system. Available in a range of lengths and colours, these channels are suitable for DIY projects and trade installations alike.

What is a purlin receiver channel?

A receiver channel is a C-shaped steel section fixed along the top of a beam that the roof sheets sit into and are fixed to, giving a clean, supported edge to lock the roofing profile in place. ClickSteel stocks it as RECEIVER CHANNEL 3600MM COLORBOND®️ steel and RECEIVER CHANNEL 7200MM COLORBOND®️ steel to suit different beam lengths. It’s a structural fixing accessory used in patio and pergola roof builds rather than a roof sheet in its own right. Length is chosen to match your beam run, joined where needed for longer spans with an INLINE BEAM CONNECTOR.

What is the difference between a channel and a purlin?

A purlin is a horizontal structural member that spans between rafters or trusses to support roof sheeting across a roof area, while a receiver channel is a fixing section that sits on top of a beam and receives the roof sheets directly, common in patio and pergola construction. ClickSteel’s RECEIVER CHANNEL 3600MM COLORBOND®️ steel and RECEIVER CHANNEL 7200MM COLORBOND®️ steel serve this receiving role on a patio beam. Purlins are typically a separate structural product used in larger roof or shed structures. Which one your build needs depends on the structure type and span, so check with your builder for the correct approach.

How do you join C channel purlins?

C-section channel or purlin lengths are joined with an inline connector that overlaps or sits inside both ends, keeping the join aligned and structurally sound along the run. ClickSteel stocks an INLINE BEAM CONNECTOR for joining beam and channel sections, alongside receiver channel lengths like RECEIVER CHANNEL 3600MM COLORBOND®️ steel and RECEIVER CHANNEL 7200MM COLORBOND®️ steel for longer runs. The join should be positioned and fixed according to the manufacturer’s structural detail, not just butted together. Confirm the correct connector and fixing method with your builder for a structurally sound result.

How far should roof sheets overhang a gutter?

Roof sheet overhang past a gutter or receiver channel is typically a modest amount, enough to direct water cleanly into the gutter without dripping behind the fascia, and the exact figure depends on the roofing manufacturer’s installation guide for your specific profile. This detail applies at the receiver channel end of a patio roof just as much as at a house gutter line, and ClickSteel’s RECEIVER CHANNEL 3600MM COLORBOND®️ steel and RECEIVER CHANNEL 7200MM COLORBOND®️ steel are fixed to set the sheet’s supported edge correctly. Getting the overhang wrong can cause water to track back under the roof sheet. Check the manufacturer’s installation instructions for your specific roof profile before fixing sheets.

How is a receiver channel fixed to a wall?

A receiver channel used at a wall junction is fixed with appropriate wall fasteners into solid structure, masonry, timber frame or as engineered for the wall type, positioned to support the roof sheeting edge correctly and matched to the beam or wall detail on the build. ClickSteel’s RECEIVER CHANNEL 3600MM COLORBOND®️ steel and RECEIVER CHANNEL 7200MM COLORBOND®️ steel are supplied as the structural material, with fixing method depending on your specific wall type and structural detail. This is a structural fixing, so it should follow an engineered detail or your builder’s specification for the wall construction involved. Confirm fixing type and spacing with your builder before installation.
