Who Is Robertson Building Systems?
For over 150 years, Robertson Building Systems has been a pillar of the Canadian custom-engineered building industry. Founded in 1863, the company is now a primary brand within Cornerstone Building Brands, North America's largest supplier of residential and commercial building solutions. Strategically headquartered in Burlington, Ontario, and supported by a vast network of manufacturing facilities across Western Canada and the Maritimes, Robertson delivers innovative, high-quality building envelopes tailored to the unique demands of the Canadian market. Every profile is backed by deep local knowledge of regional snow loads and wind requirements, making them a trusted partner for builders from British Columbia to Newfoundland.
Why Specialized Fall Protection is Crucial for Robertson Roofs
Safety is paramount when working on high-performance standing seam panels. Because Robertson systems utilize concealed fasteners and floating designs to manage thermal expansion, traditional penetrating anchors are strictly prohibited. Drilling into these panels causes immediate leaks and voids the manufacturer's warranty. Contractors must utilize specialized, non-penetrating anchors that clamp to the standing seams to preserve structural integrity while providing a certified tie-off.
To ensure 100% tie-off without voiding warranties, we recommend the following non-penetrating products:
- SSRA1 Seam Anchor: The foundational component. It features a one-piece body and a patented design that fits 95% of today's standing seam profiles, including large mechanical ribs, without disassembly.
- SSRA2 Adjustable Roof Jack Adapters: Brackets that mount directly to the SSRA1 to support 10-foot wooden walk-boards for stable footing on steep Canadian roof slopes.
- SSRA3 Anchor Plates: High-strength plates that connect two SSRA1 anchors into a single assembly to create heavy-duty endpoints for lifelines.
- 100-foot SSRA HLL Kit: A temporary mobility solution including four anchors and a 100-foot kernmantle rope rated for two workers.
- 120-foot Super Anchor Permanent HLL: A long-term maintenance solution using non-penetrating 5-inch riser posts that allow the floating roof to move naturally during thermal shifts.
- Ridge Pro Steep Assist: The essential First-Man-Up tool for pitches between 6:12 and 12:12, providing immediate tie-off before leaving the ladder.
Keep in mind that OSHA and ANSI standards limit horizontal lifeline systems to a maximum pitch of 4:12. OSHA recognizes that workers can lose their footing and slide on steeper roofs, leading to dangerous swing falls that are not suitable for horizontal lifeline setups.
Proper Attachment: Set-Screws and Torque Requirements
Installers must match the fastener and torque setting to the specific Robertson panel gauge to ensure certified holding power and finish preservation:
- Cupped-Tip Stainless Steel Set Screws: Use these screws exclusively on 22-gauge steel panels. Torque these screws to 90 inch-pounds.
- Nylon-Tipped Set Screws: For use with 22-gauge or 24-gauge steel panels where preserving the paint finish is the priority. Torque these fasteners to 180-200 inch-pounds.
- Maintenance: Treat nylon tips as consumables. Replace these tips every 3 to 5 uses to maintain maximum grip strength.
CRITICAL WARNING: NO IMPACT GUNS
Warning: Always use a calibrated torque wrench for final installation. Never use an impact gun to install set-screws. Impact guns can quickly over-tighten the screws, resulting in permanent damage to the standing seam panel or the anchor itself. This error compromises the anchor's certified holding power and voids the hardware warranty.

Certified Protection: U.S. Engineering vs. Unbranded Imports
A Robertson building represents a premium, engineered investment designed to survive Canada's harshest environments. Your fall protection must meet that same professional standard. The market is currently targeted by unbranded, generic imported anchors that lack verifiable load testing or alloy certifications. These inexpensive substitutes are a liability that could lead to a Willful Violation during a site inspection. In a courtroom event following a fall, using uncertified safety hardware leaves the employer as the sole target for legal action.
The American-made SSRA1 Standing Seam Roof Anchor provides a sharp contrast. Precision-machined from solid 6061-T6 aluminum and validated at independent laboratories, our hardware has withstood test loads exceeding 14,500 pounds—nearly triple the OSHA 5,000-lb requirement. Choosing certified domestic hardware replaces high-risk guesswork with verifiable reliability that protects your crew and your firm's liability. Review our technical results in our independent laboratory test reports.

10 Essential Safety Guidelines for Robertson Building Systems Projects
Staying safe on a Robertson roof requires more than just the proper anchors; it requires a total commitment to safety culture. Here are ten essential strategies to keep your team protected while preserving the integrity of these high-performance systems.
1. Enforce First-Man-Up Protocol
On pitches between 6/12 and 12/12, never step onto the roof without The Ridge Pro. This device ensures the worker is 100 percent tied off the moment they transition from the ladder to the peak.
2. Verify Torque Settings Daily
Set-screw tension is not a set-and-forget task. Use a calibrated torque wrench every morning to ensure anchors remain at their required specifications. Vibration and thermal shifts can affect tension.
3. Eliminate Clip-Location Guesswork
Traditional anchors force contractors to search for hidden clips beneath the panel to ensure a secure hold. The SSRA1 eliminates this frustration by securing directly to the seam, providing a certified 5,000-pound tie-off point regardless of clip location.
4. Stop No-Name Liability
Avoid unbranded, imported knock-off anchors. If an anchor lacks a verifiable 3rd-party test report for compliance with OSHA 1926.502 and ANSI standards, it poses a liability risk that could lead to site-wide shutdowns.
5. Neutralize the Pendulum Effect
Always calculate your dynamic sag and fall distance. Keep the work zone within a 30-degree arc of the anchor point to prevent dangerous swing falls that could result in collisions with lower building structures.
6. Preserve Thermal Flexibility
Robertson panels float to manage Canada's extreme temperature swings. Only use non-penetrating clamps that allow for this natural thermal expansion, preventing the panels from buckling or oil-canning.
7. Defend Against Galvanic Corrosion
Never mix incompatible metals. Use only Stainless Steel set screws on Robertson steel panels to prevent chemical reactions that lead to rust and structural failure.
8. Mitigate Suspension Trauma
Equip every worker's harness with Suspension Trauma relief straps so the fallen worker can stand and relieve pressure on the femoral arteries while waiting for rescue.
9. Protect the Panel's Structural Integrity
High-torque, two-piece anchors can crush standing seams, damaging the roof and voiding warranties. Prioritize the SSRA1 low-torque design, which requires only 90 inch-pounds on 22g steel to achieve a full-strength lock.
10. Consult Specialists for Complex Roof Shapes
Custom Robertson projects often feature curved, serpentine, or convex rooflines. A qualified safety professional must perform a mandatory on-site inspection of these specialized profiles before deploying any fall protection hardware.
