Snow Guards for Union Corrugating
Snow guards for Union Corrugating Company roofing panels help control rooftop snow and ice movement above entrances, sidewalks, driveways, parking areas, landscaping, mechanical equipment, and other locations where sliding snow can create damage or safety concerns. The correct SnoBlox-Snojax system depends on whether the project uses a standing-seam concealed-fastener panel or an exposed-fastener metal roof panel, and then on the specific Union Corrugating panel profile installed.
- Union Corrugating Company standing-seam and exposed-fastener panels require different snow-retention attachment methods.
- Standing seam panels should use compatible clamp-on rail or cleat systems, or adhesive-mounted guards when the panel has a suitable bonding surface.
- Exposed-fastener panels may accept adhesive, screw-down, SnowCatcher, PBR rail, or 2.67 corrugated systems depending on rib geometry and available mounting area.
- Corrugated exposed-fastener panels require special attention because standard flat-mounted pad guards are not appropriate for every wavy profile.
- Final product selection should consider roof slope, panel width, snow load, run length, roof material, panel striations, and the full roof layout.

About Union Corrugating Company Roofing Systems
Union Corrugating Company traces its roots to 1946 in Fayetteville, North Carolina, when J.E. Union started the company with a manually operated corrugating machine. The company became known locally after Hurricane Hazel in 1954, when demand for metal roofing surged, and the business chose to maintain standard pricing rather than capitalize on the surge. That customer-focused approach helped shape the company's long-term reputation as a reliable metal roofing supplier. Today, Union Corrugating serves residential, commercial, agricultural, and post-frame roofing markets from multiple manufacturing facilities across the central and eastern United States. Because Union Corrugating panels vary by seam height, rib spacing, fastening method, material, coverage width, and surface pattern, snow guard compatibility should always be matched to the exact panel profile.
Snow Retention Solutions for Union Corrugating Company Roofing
Union Corrugating Company offers both concealed-fastener standing seam profiles and exposed-fastener roofing panels. These roof styles require different snow retention strategies. Standing seam panels typically use non-penetrating clamp-on systems when the seam shape allows it, or adhesive-mounted polycarbonate guards when a flat bonding surface is available. Exposed-fastener panels may accept screw-down products when fastened through the correct mounting area and into adequate structure.
See our full range of snow guards for metal roofs and use the charts below to confirm which SnoBlox-Snojax products fit each Union Corrugating Company panel. “YES” indicates the product is shown as a fit for that panel. “NO” means it is not shown as compatible for that profile.
Snow Guards for Union Corrugating Company Standing Seam Roof Panels
Union Corrugating Company standing seam profiles include Advantage-Lok II, SL150, SL175, ML200, ML150, and TS-324. These panels vary by seam height, seam style, panel width, material, installation method, and whether they are snap-lock, mechanically seamed, or trapezoidal standing seam systems.
Standing seam warning: Do not install screw-down snow guards through concealed-fastener standing-seam roof panels. Use compatible clamp-on products where the seam accepts them, or adhesive-mounted guards where a flat bonding surface is available.

The Advantage-Lok II, SL150, SL175, ML200, ML150, and TS-324 profiles all show broad standing seam compatibility across adhesive-mounted polycarbonate snow guards, clamp-on rail systems, RCB-3 rail systems, 2-bar rail systems, and clamp-on SnoCleat options.
Striated panels may require a heavier adhesive application to fill small gaps and reduce moisture paths beneath the guard. If using a rail system, IceStopper attachments are recommended above pedestrian or parking areas to help manage snow and ice beneath the rail.
Snow Guards for Union Corrugating Company Exposed Fastener Roof Panels
Union Corrugating Company exposed fastener profiles include MasterRib, 7/8-inch Corrugated, 2-1/2-inch Corrugated, 5V, and PBR panels. These profiles do not share the same rib spacing, rib height, corrugation shape, or low-flat mounting area, so snow guard compatibility changes significantly from one panel to another.
Exposed fastener reminder: When screw-down snow guards or rails are compatible, they should be attached through the correct mounting area and into adequate structure. Standard exposed-fastener products typically mount through the low flats. At the same time, 2.67 corrugated systems are designed for compatible corrugated profiles and use the appropriate corrugated bracket attachment method.

The 5V profile accepts the broadest range of exposed-fastener snow retention options, including polycarbonate guards, SnowCatcher products, SnoCleat PBR, PBR-style rail systems, and 2.67 corrugated products.
MasterRib and PBR panels are compatible with selected pad-style guards and rail systems. In contrast, 7/8-inch Corrugated and 2-1/2-inch Corrugated panels require 2.67 corrugated systems because their wavy profiles are not suited for standard flat-mounted pad guards.
When using screw-down products, always verify that fasteners engage adequate structure beneath the panel. When using adhesive-mounted polycarbonate guards, follow the recommended adhesive and cure-time guidance for the project conditions.
Union Corrugating Company Snow Guard Buying Checklist
- Confirm the exact Union Corrugating Company panel name before choosing any product.
- Identify the roof type: standing seam, concealed fastener, exposed fastener, PBR-style, or corrugated.
- Verify the attachment method: adhesive, screw-down, clamp-on, PBR bracket, or 2.67 corrugated bracket.
- Check ground snow load. Individual glue-down or screw-down guards are generally best suited for lighter snow-load applications. At the same time, higher loads often require rail systems.
- Request a layout rather than installing only in isolated areas such as doors, chimneys, or HVAC equipment.
- Order samples or single units when a test fit is needed. SnoBlox-Snojax products and components are available with no minimum order requirement.

Compatibility Guidance Note
SnoBlox-Snojax bases the compatibility information presented in this guide on product testing and field experience with Union Corrugating Company metal roof panel profiles. Panel manufacturers periodically update profile specifications, and individual project variables, such as seam condition, coating type, and installation method, can affect outcomes. Customers are encouraged to confirm current panel specifications directly with Union Corrugating Company and to contact SnoBlox-Snojax with project-specific questions before ordering.
