Steel Tubular Snowguards SG1 are a non-penetrating snow retention system engineered specifically for standing seam metal roofs. Rated at 5 kN/m static load (SS 831367), SG1 clamps attach directly to the standing seam rib — no drilling, no penetrations through the panel surface, roof warranty fully preserved.

Engineered for standing seam

Unlike universal snow guards, SG1 is purpose-built for standing seam profiles — mechanical lock (single and double) and snap-lock. The clamp grips the seam rib mechanically, transferring snow load to the roof structure without a single hole in the panel.

Why steel, not aluminum

SG1 is zinc-coated steel — higher load capacity than aluminum, and no galvanic corrosion on steel roofs. Aluminum snow guards clamped to a steel panel corrode at the contact point over time. Steel-on-steel contact eliminates that risk entirely.

Key specifications

• Load rating: 5 kN/m static load (SS 831367)
• Hot-dip zinc coating: 275 g/sq.m for corrosion resistance
• Oval tube: 25 x 45 mm — optimized load distribution
• Tube length: 3 m sections
• Bracket spacing: up to 1.2 m (4 ft)
• Non-penetrating clamp connection to standing seam rib

SG1 vs SG2

SG1 is optimized for standing seam roofs with clamp-on connection. If you need snow guards for shingle roofs, straight-rib panels, or other roof types requiring a screw connection, see our SG2 universal system.

Ordering

SG1 is supplied in 3 m sections with brackets. Quantity and layout depend on roof slope, length, and local snow load per NBC 2020. Use our snow retention calculator for a preliminary layout, or call for a quote.
