Who Is Drexel Metals?
Drexel Metals built its reputation by pairing American manufacturing with dependable standing seam roofing systems that perform in the real world. Drexel Metals was founded in 1985 with a simple mission: to provide consistent, high-quality painted metal roofing panels. The company shifted into a new gear in 2009 when it became Drexel Metals Inc. That growth continued in 2011, following the acquisition of Met-Fab Manufacturing. This move expanded its custom fabrication capabilities and deepened its footprint in the architectural metal market.
Today, Drexel operates multiple sales, fabrication, and distribution locations across the country. Contractors, builders, and architects rely on Drexel for engineered metal roofing systems, portable roll-forming equipment, custom trim fabrication, and a long list of accessories that keep projects moving. Drexel Metals manufactures an extensive lineup of standing seam profiles in pre-painted Galvalume, pre-painted aluminum, Drexlume, and copper. The company keeps production in the United States, which matters when consistency and quality are top priorities. Between the color options, coating systems, gauges, and panel widths, Drexel gives builders the flexibility to match performance with design in a way that feels almost custom.
Non-Penetrating Fall Protection Solutions Are Critical For Drexel Metals Standing Seam Systems
Workers stay safer on Drexel Metals panels when they use non-penetrating anchors that protect the seam profile and maintain the roof warranty. Drexel standing seam systems offer the strength, weather resistance, and architectural detail that metal roof installers seek. Still, they require safety equipment that grips the seams without creating holes or weakening the weather-tight seal. Any seam penetrations can cause panel distortion, leaks, and warranty issues on Drexel Metals standing seam panels.
This article provides installers, safety managers, and building owners with a clear overview of the fall protection equipment that fits Drexel Metals' standing-seam profiles. It also explains why compatible anchors, horizontal lifeline systems, and steep-assist devices create a safer workflow from the first ladder step to the final piece of trim. You will see a breakdown of Drexel's main standing-seam profiles and the most compatible fall-protection solutions for each. When the appropriate anchors match the panel, workers stay properly tied off, and OSHA compliance becomes easier.
- SSRA1 Standing Seam Roof Anchor: The foundation of the system. This anchor attaches to the seam with stainless-steel set screws at low torque, providing a 5,000-lb certified tie-off point.
- SSRA2 Adjustable Roof Jack Adapters: Mount directly to SSRA1 anchors to support ten-foot wooden walkboards, providing installers with a level work surface on steep metal roofs.
- SSRA3 Anchor Plate: Heavy-duty aluminum plates that secure across two SSRA1 anchors to serve as certified endpoints for horizontal lifelines.
- SSRA HLL 100-foot Temporary HLL Kit: A complete turnkey system for up to two workers in fall arrest, allowing safe lateral movement across wide spans.
- Super Anchor 120-foot Permanent HLL Kit: An industry-exclusive galvanized steel cable solution for roofs requiring regular maintenance without penetrations.
- Ridge Pro Steep Assist Anchor: A ridge-mounted anchor for initial access and safety on 6:12 to 12:12 pitches, providing 100% tie-off from the ladder to the ridge.
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. This installation error damages the anchor hardware, compromises worker safety, and voids the manufacturer's warranty. Always use a calibrated torque wrench for final installation.

Why Budget Fall Protection Imports Compromise Drexel Roof Integrity
Many low-cost anchors flooding the market are manufactured with inferior alloys and lack the transparent, verifiable testing required for industrial-grade safety. These "knock-off" systems often rely on self-certification or generic documentation that doesn't account for the specific shapes and structural gauges found on Drexel Metals structural panels.
We replace that uncertainty by providing direct access to our 3rd-party, ISO 17025-accredited laboratory results. Our American-engineered SSRA hardware can withstand dynamic loads exceeding 5,000 lbs. By insisting on hardware backed by transparent domestic engineering and certified lab reports, you ensure that your fall protection is every bit as advanced and reliable as the Drexel Metals building envelope it protects.

Essential Safety Strategies for Standing Seam Metal Roofing Contractors
- Mandate Cleaning Protocols: Before locking down an SSRA1 Standing Seam Roof Anchor, verify the seam is free of grease, debris, or morning dew. Residual oils from the roll-forming process can reduce the grip of set screws. A quick wipe with a rag ensures the 5,000-lb. certified hold remains intact, protecting the crew and the Drexel Metals finish.
- Deploy Steep Slope Walkboard Staging: For pitches 6:12 and higher, do not just lean into the roof. Use SSRA2 Adjustable Roof Jack Adapters to stage 10-foot walkboards on standing seam roofs. Providing a level standing surface drastically reduces lower back fatigue and prevents ankle burn.
- Impact Wrench Warning: Over-tightening is as dangerous as under-tightening. Use a calibrated torque wrench for 90 inch pounds torque for stainless cupped tipped screws or 180 - 200 inch pounds for nylon tipped screws. This precision preserves the Drexel Metals thermal expansion clips and ensures the anchor does not crush the rib.
- Transition to Leading Edge SRLs: Standard lifelines are not enough when working around the sharp edges of Drexel 200S or 175S panels. Ensure every worker uses Leading Edge (LE)- rated Self-Retracting Lifelines. These products withstand falls where the cable might snag on sharp metal edges.
- Implement the "First Man Up" Rule: Transitioning from ladder to roof is high-risk. Use the Ridge Pro Steep Assist Anchor to establish a 100 percent tie-off point at the ridge before any worker steps off the ladder. This strategy allows for a safe, vertical lifeline descent down to the eaves.
- Use Horizontal Lifelines for Maximum Worker Mobility: Install temporary horizontal lifeline systems, such as the SSRA HLL 100-foot Kit, to provide your crew with continuous, hands-free protection across large roof spans. These systems allow lateral movement along Drexel panels without disconnecting. Keep in mind that horizontal lifelines are limited to 4:12 pitch or less.
- Standardize Trauma Strap Integration: Suspension trauma can kill in minutes. Require Suspension Trauma Straps on every harness. If a worker falls, these straps allow them to stand up while hanging, relieving pressure on the femoral arteries and buying critical time for rescue.
- Enforce Roofing Footwear: Smooth Galvalume and painted aluminum are slippery when dusty. Contractors should mandate roofing-specific boots with rubber soles. These sticky soles provide maximum friction on Drexel architectural coatings, preventing slips before they occur.
- Establish Permanent Maintenance Lifelines: If the building requires routine HVAC or gutter service, consider installing a Super Anchor 120-foot Permanent HLL Kit. It protects the roof from damage caused by future contractors using the wrong anchors.
- Conduct Daily Dynamic Load Tool Talks: Good safety managers lead a five-minute huddle every morning to review the day's specific roof hazards and tie-off points. Daily safety meetings ensure that every worker understands the required safety protocols and hazards before stepping onto the Drexel panels.
