Screw Down ColorBar Snow Retention System for Metal Roofs – Heavy-Duty Aluminum Snow Bar

Canada Snow Guards · Genuine SnoBlox-Snojax

Colour-matched snow retention for exposed-fastener metal roofs: a 6061-T6 aluminum ColorBar rail on drop-in ColorBracket™ mounts, anchored through the panel flat into structural wood or steel purlins — not just into the panel skin. Gasketed, sealed fastening at every penetration holds the snowfield for a controlled melt instead of a roof avalanche, and the aluminum rail reads as part of the roof rather than a bolt-on.

Mix and match: every snow bar and rail in your cart counts toward the same quantity break.

6061-T6 aluminum, not steel

Every ColorBar rail is 6061-T6 aluminum — the structural temper, not soft extrusion stock. On a screw-down roof that matters twice over: aluminum will not bleed rust down a coated panel from a cut end or a fastener contact point, and putting aluminum against an aluminum or coated-steel panel avoids the galvanic mismatch you invite when bare steel sits on a finished roof. It also stays dimensionally stable through Canadian freeze–thaw cycling and is light enough to carry up a ladder in full lengths.

Anchored into structure, not into the panel

Exposed-fastener roofs have no seam to clamp, so this system is fastened — and fastening only works if the screw reaches something structural. Each ColorBracket™ drops in and is anchored through the flat of the panel into the purlin or deck below, with a gasketed, sealed fastener at every hole. A snow guard fixed only to the panel skin will tear the panel before it stops a slide; this one transfers the load into the frame.

Choosing your configuration

Two things decide your variant. First, your panel width: a 9″ flat takes a bracket every 18″, a 12″ flat takes one every 12″. Second, what you are screwing into — wood purlins or metal purlins — which changes the fastener that ships with the kit. Pick the combination above. If you do not know your panel width, measure flat-to-flat between two ribs and send us a photo; we will confirm it before you order.

Fits

• Exposed-fastener / screw-down metal roofs — ag panel, R-panel, PBR and similar profiles
• 9″ and 12″ flat panel widths
• Wood purlins or metal purlins (select your fastener package above)
• Coated and painted panels where the retention system needs to match the roof colour
• Critical zones: entries, walkways, garage doors, gas meters, HVAC and vehicle parking

What's included

• 1.8 m (6 ft) ColorBar rail — 6061-T6 aluminum
• Drop-in ColorBracket™ mounts at your selected spacing
• Gasketed structural fasteners matched to wood or metal purlins
• Sealant and mounting hardware

Installation at a glance

• Locate your purlins first — bracket placement follows the structure, not the panel pattern.
• Sections join end-to-end across the roof face; row count and placement come from your engineered layout.
• Every penetration is gasketed and sealed; install above freezing where possible so the sealant sets properly.
• Protecting a vent in the field above? Add a VentSaver diverter to the same order.
