Snow Guards For Sheffield Metals

Snow guards for Sheffield Metals roofing panels help manage rooftop snow and ice above entrances, walkways, parking areas, landscaping, and equipment. Choosing a suitable SnoBlox-Snojax system starts with identifying the precise Sheffield Metals standing seam profile and confirming its attachment options.

• The five mechanical seam profiles and two 450-series snap lock profiles in this guide accept adhesive guards and compatible clamp-on systems.
• SMI 1.0 Fastener Flange, SMI 1.5 Fastener Flange, SMI 1.5 SnapLock 550, and SMI 1.75 SnapLock accept adhesive-mounted guards only.
• SnowBreaker breaks moving snow into smaller pieces; choose pad-style guards or rails when the project calls for snow retention.
• Roof slope, snow load, panel width, roof material, coating, striations, and roof run length all affect system selection and layout.

Find your panel group here, then confirm each product in the compatibility charts below.

• SMI 1.0 MS, SMI 1.5 MS, SMI 2.0 MS, SMI 2.0 MS Armco, and SMI 2.0 SCH MS: Adhesive-mounted polycarbonate guards, SnoBar/ColorBar standing seam rails, RCB-3 rails, 2-bar rails, and SnoCleat RC/RCT are listed as compatible.
• SMI 1.5 SnapLock 450+ and SMI 1.5 SnapLock 450 SL: These two snap lock profiles accept the same adhesive and clamp-on product groups.
• SMI 1.0 Fastener Flange, SMI 1.5 Fastener Flange, SMI 1.5 SnapLock 550, and SMI 1.75 SnapLock: Use adhesive-mounted guards. The listed clamp-on rails and SnoCleat products are not compatible.
• Standing seam warning: Do not penetrate these roof panels with screw-down snow guards.

The charts list adhesive-mounted products for all 11 profiles and compatible clamp-on products for five mechanical seam profiles and two 450-series snap lock profiles. Choose between adhesive guards and clamp-on systems based on the roof's snow load, dimensions, and approved layout. The correct clamp hardware must still match the installed seam.

Larger polycarbonate models include IceJax II, Snojax II, and SnoBlox Ace. Ecojax, SnoBlox Deuce, and IceJax I provide smaller pad-style options. Aluminum roofing may require additional rail rows to spread the retained load.

Use IceJax I, IceJax II, Ecojax, SnoBlox Deuce, SnoBlox Ace, or Snojax II where an adhesive-mounted retention guard is appropriate. SnowBreaker is an option for breaking up sliding snow. SnoBar, ColorBar, RCB-3 rails, 2-bar rails, SnoCleat RC, and SnoCleat RCT are marked NO for these four profiles.

On striated panel pans, the adhesive bed must fill the grooves beneath the guard base. Follow the installation instructions to obtain full contact and avoid moisture pockets.

Plan SureBond SB-190 installations for approximately 28 days at 50°F or warmer so the adhesive can fully cure. Initial resistance to moisture is not the same as a complete cure. Confirm roof finish and material suitability before bonding; do not use SB-190 for copper roofing applications.

Sheffield Metals Snow Guard Buying Checklist

• Confirm the exact Sheffield Metals panel name and distinguish the 450-series profiles from SnapLock 550 and SMI 1.75 SnapLock.
• Check the seam and panel pan: Verify the installed profile, panel width, coating, roof material, and available bonding surface.
• Choose a listed attachment method: Adhesive guards work across the profiles shown; clamp-on systems work only on the seven compatible profiles shown in the charts.
• Check ground snow load: Confirm that the selected system is appropriate for the project’s ground snow load. Contact SnoBlox-Snojax for projects above 45 psf, especially when the panel profile accepts only adhesive-mounted products.
• Request a full-roof layout: Provide the roof slope, eave-to-ridge measurements, seam spacing, and building location rather than placing guards only above individual doors or equipment.
• Order samples or single units when you need a test fit. SnoBlox-Snojax products and components are available with no minimum order requirement.
• Plan adhesive installation timing around the full SB-190 cure period and follow the product instructions.
