Who Is Merchant and Evans?
Merchant and Evans has been part of the American roofing landscape for more than a century. The story begins in 1866, when the company supplied metal products to builders who needed dependable materials that could withstand demanding environments. Things changed in a big way in 1964 when Merchant and Evans introduced the ZIP RIB system, a structural standing-seam roof based on a Kaiser Aluminum innovation. That system became a turning point for the entire industry. Crews finally had a panel that locked mechanically, carried its own structural load, and stayed weather-tight through decades of abuse.
The ZIP RIB panel quickly became the signature roof in their catalog. It performed well in harsh climates, over long spans, and in complex roof designs that other panels struggled with. Once architects realized they could curve, taper, and wrap it around almost anything without sacrificing strength, ZIP RIB began appearing on projects worldwide. Merchant and Evans never drifted from that original focus on engineering. The company produces roofing, wall panels, fascia, soffit systems, perimeter trims, and accessories that give architects freedom to build whatever they can sketch. Their partnership with IMETCO strengthened that approach, giving them more capacity, better tooling, and an expanded range of high-performance solutions.
Non-Penetrating Fall Protection Solutions Are Critical For Merchant and Evans Standing Seam Systems
Safe work on Merchant and Evans panels starts with understanding the seams, the metal, and which anchors protect both. These roofs appear on projects where performance matters, often involving tall buildings, long spans, and architectural details that challenge traditional safety plans. Every anchor must sit correctly on the seam, match the metal gauge, and protect the weather-tight seal for which Merchant and Evans panels are known.
Choosing non-penetrating fall protection is the only responsible option for Merchant and Evans standing-seam profiles. This guide walks safety managers, installers, and building owners through each panel, explaining which fall protection systems best match the seam shape and substrate.
- SSRA1 Standing Seam Roof Anchor: A universal non-penetrating anchor that attaches to the seam using 12 stainless-steel set screws, providing a 5,000-lb certified tie-off point without drilling.
- SSRA2 Adjustable Roof Jack Adapters: Adapters that mount to SSRA1 anchors to support a 10-foot walk board, allowing workers to stand on a level surface on steep-slope roofs.
- SSRA3 Anchor Plate: A heavy-duty aluminum plate that spans two SSRA1 anchors to create a certified attachment point for horizontal lifeline systems.
- SSRA HLL 100-foot Temporary Horizontal Lifeline Kit: A complete, portable lifeline system for up to two workers that allows safe lateral movement across wide roof sections without panel penetrations.
- Super Anchor 120-foot Permanent Horizontal Lifeline Kit: A long-term safety solution featuring galvanized steel cables and non-penetrating riser posts for facilities requiring frequent maintenance access.
- Ridge Pro Steep Assist Anchor: A ridge-mounted anchorage device that hooks over the peak to provide safe vertical lifeline access on pitches from 6:12 to 12:12.
Proper Attachment: Set-Screws and Torque Requirements
- 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: Apply these tips to 22-gauge or 24-gauge steel panels to achieve certified holding power without marking the finish. Torque these screws 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
Never use an impact gun to install set-screws. Over-torquing with an impact driver crushes the standing-seam rib, causing permanent panel deformation and compromising the anchor's certified holding power. Always use a calibrated torque wrench for final installation.
Merchant & Evans Zip-Rib Mechanical Panel (SSRA Compatible 22/24 ga. Steel)
The Zip-Rib panel has been the signature profile of Merchant & Evans since 1964. Its 2.5-inch structural rib acts like a miniature beam, providing incredible strength across spans of 400 feet or more. This mechanically locked system is a staple for universities, transit hubs, and sports facilities. It is available in 20-, 22-, and 24-gauge steel, as well as .032 to .050 aluminum. See the Roof Anchor Compatibility Chart for Merchant and Evans Zip-Rib Standing Seam Panels.

CRITICAL WARNING: INSPECTION REQUIRED
Tapered or radius B1515R applications alter force distribution and require professional inspection before equipment selection.
Merchant & Evans 114-R Box-Seam Panel (Ridge Pro Only)
The 114-R is an architectural box-seam panel with 1.25-inch-high by 1.25-inch-wide seams. It is available in aluminum and 22-gauge and 24-gauge steel. The box-seam shape prevents standard seam anchors from achieving a certified grip. See the Roof Anchor Compatibility Chart for Merchant and Evans 114-R Standing Seam Panels.
Fall Protection For Merchant and Evans 114-R Panels
- Ridge Pro Steep Assist Anchor: The safest and most predictable choice for 114-R panels on slopes between 6:12 and 12:12.
- Constraint: The box-seam profile rules out seam-mounted anchors (SSRA1, SSRA2, SSRA3).
Performance Over Price: The Value of Certified Anchorage
While budget-priced, imported anchors may look identical to professional systems, they often lack the structural strength and dynamic load testing necessary for industrial safety. Choosing an uncertified alternative introduces an unknown variable into your fall protection plan, potentially jeopardizing both your workers and your liability.
We eliminate this risk by providing complete transparency through our dedicated testing page. Our hardware is engineered in America and verified by an ISO 17025-accredited laboratory to exceed 5,000-lb dynamic load requirements.

Safety Tips For Standing Seam Roofs
- Equip Workers with High-Quality Safety Gear: A harness that hugs the worker correctly, a Malta Dynamics SRL that pays out smoothly, and connectors that pass inspection give workers confidence. OSHA harness fit standards are critical for 2026 compliance.
- Set Up Protective Guardrail Barriers for Work Zones: Guardrails rank among the simplest ways to keep crews safe. They block off skylights, edges, and staging zones, providing a physical boundary for workers.
- Consult Experts for Curved Metal Panels: A conical taper, dome surface, or long curved panels require additional scrutiny. A fall protection expert should evaluate those designs before choosing anchors to prevent damage to curved ZIP-RIB or B1515R installations.
- Use Specialized Anchor Systems for Standing Seam Roofs: Standing seam systems demand anchors that grip without breaking the weather-tight seal. SSRA1 anchors use stainless steel set screws that apply low-torque pressure across a 12-inch span rather than high-torque at concentrated points.
- Promote a Culture of Safety: A five-minute conversation before work begins has more influence than any manual. Encouraging workers to point out concerns creates safer job sites.
- Encourage the Use of Trauma Straps: Trauma straps give a suspended worker a way to stand, shift their weight, and avoid circulation problems as the rescue plan unfolds. Safety managers should treat these as required equipment.
- Develop OSHA-Compliant Safety Plans: A written plan identifies anchor points, defines restraint vs. arrest work, and outlines rescue procedures. Site-specific plans reduce improvisation risk.
- Prioritize Ladder Safety Training: Review the 4-to-1 setup rule, maintain three points of contact, and inspect rails/rungs daily. Ladder sloppy habits usually translate to roof accidents.
- Install Permanent Roof Anchor Systems: For roofs requiring ongoing HVAC or seasonal service, a Super Anchor Permanent HLL eliminates repeated temporary installations and maintains the weather-tight seal.
- Ensure Proper Footwear for Stability: Slip-resistant boots with firm ankle support are essential for smooth Kynar finishes. Proper traction paired with a secure tie-off point is the foundation of safety.
