Heavy-Duty Steel Rail
SnoBar uses a 1-inch-square, GatorShield-coated galvanized steel rail profile. The flat face provides a strong retention surface for snow and ice compared with round or angled bar profiles.
SnoBar Snow Retention System
SnoBar Snow Rail System for Metal Roofs
SnoBar is a heavy-duty bar-style snow retention system for compatible standing seam and exposed-fastener metal roofs. It uses a 1-inch square rail profile designed to help control dangerous sliding snow and ice while offering a durable, functional appearance.
What Is SnoBar?
SnoBar is the steel snow rail option in the SnoBar and ColorBar product family. It is commonly selected when a strong, economical, heavy-duty bar system is preferred for metal roof snow retention.
The system is built around a 1-inch square GatorShield-coated galvanized steel bar that can be used with standing seam clamp mounts or screw-down brackets, depending on the roof panel type. SnoBar is available in mill finish or powder-coated finish options, and stainless steel bar options may be used for selected applications.
SnoBar System Features
SnoBar is designed for functional snow retention, fast installation, and broad compatibility across common metal roof applications.
Multiple Finish Options
SnoBar comes standard with a mill-galvanized finish and can optionally be powder-coated to match the roof. Stainless steel bar options are also available for selected applications.
Roof-Specific Mounting
SnoBar for standing seam roof systems uses non-penetrating clamps that attach to compatible roof seams. Exposed-fastener metal roof systems use screw-down brackets secured to structural support below the panel.
Optional IceStopper
IceStoppers that extend from the bar down to the panel are recommended in selected areas, such as pedestrian walkways or parking lots, to help control ice and snow from sliding beneath the bars.
SnoBar Attachment Options
SnoBar can be configured for compatible standing seam or exposed-fastener metal roofs. The correct attachment method depends on the roof panel profile and project conditions.
Standing Seam SnoBar
Clamp-mounted SnoBar systems attach to compatible standing seam panels without penetrating the roof panel.
Standing Seam Options
Screw-Down SnoBar
Screw-down SnoBar systems attach through the panel into structural support on compatible exposed-fastener roofs.
Screw-Down OptionsSnoBar Systems by Roof Type
The correct SnoBar system depends on whether the roof is standing seam or exposed-fastener, along with panel spacing, roof pitch, roof run, eave length, and project location.
SnoBar for Standing Seam Metal Roofs
Clamp-on SnoBar systems attach to compatible standing seam panels without penetrating the roof panel. Clamps are selected based on seam profile, seam spacing, roof layout, and loading requirements.
- Non-penetrating attachment on compatible seams
- Top-loading clamp-mounted SnoBar rail system
- Installed on standing seam panels where roof penetrations are not desired
SnoBar for Exposed-Fastener Metal Roofs
Screw-down SnoBar systems attach through the roof panel into structural support. These systems are used on compatible ribbed and exposed-fastener metal roof panels.
- Top-loading bracket-mounted screw-down attachment
- Designed for fastening into purlins or decking
- Used on compatible exposed-fastener panel profiles
Snow retention layouts should be designed for the full roof area that contributes sliding snow. Do not isolate snow rails only above doors, walkways, vents, or other small areas. Upper roofs should be addressed before lower roofs when snow can shed from one roof area onto another.
SnoBar Material and System Options
SnoBar is the steel rail option. ColorBar is the aluminum rail option. Use this page when the project specifically calls for SnoBar.

Need a SnoBar Layout or Quote?
SnoBar layouts should be based on roof pitch, panel type, seam or rib spacing, horizontal eave length, roof run, snow load, roof geometry, and the project location.
Send the project information before ordering if you are unsure which clamps, brackets, row spacing, or accessories are required.

Review the correct SnoBar installation instructions based on roof type, attachment method, and whether the project uses a single-bar or two-bar snow rail layout.
Clamp-On SnoBar Instructions
Use these instructions for SnoBar systems installed on compatible standing seam metal roofs with non-penetrating clamps.
Screw-Down SnoBar Instructions
Use these instructions for SnoBar systems fastened through compatible exposed-fastener metal roof panels into structural support.
Two-Bar SnoBar Instructions
Use these instructions when the roof layout requires a two-bar SnoBar or SnoBar/ColorBar snow rail system.
Always match the installation instructions to the roof panel type and attachment method. Standing seam systems use clamp-on attachment, while exposed-fastener systems require brackets fastened into structural support.
SnoBar FAQ
Is SnoBar the same as ColorBar?
No. SnoBar is a GatorShield-coated galvanized steel snow rail system, with stainless steel options available for selected applications. ColorBar is a structural aluminum snow rail system with a slot to add a color strip in the face of the bar.
Can SnoBar be powder coated?
Yes. SnoBar is available in mill finish or powder-coated finish options for projects where a closer roof color match is desired.
Does SnoBar work on standing seam roofs?
Yes, when the standing seam panel is compatible with the selected roof clamp and the system is properly designed for the roof conditions.
Does SnoBar work on exposed-fastener roofs?
Yes, screw-down SnoBar systems can be used on compatible exposed-fastener metal roofs when brackets are fastened into structural support below the panel.
