Compatible Fall Protection For Met-Fab by Drexel Roofs

Who Is Met-Fab by Drexel?

Met-Fab, once a prominent force in the D.C., Maryland, and Virginia (DMV) metal roofing market, joined Drexel Metals in October 2011. This merger was a strategic move that elevated Met-Fab's regional expertise in custom architectural sheet metal to the national stage. By integrating Met-Fab's lineup of over 42 engineered metal roof system assemblies, Drexel Metals significantly deepened its product portfolio.

The acquisition established a vital Baltimore-based distribution hub, drastically reducing delivery times for customers along the Eastern Seaboard. Met-Fab's precision craftsmen brought their creativity and technical mastery into the Drexel fold, providing a foothold in energy-efficient roofing solutions and total building envelope components.

In July 2017, the industry landscape shifted again when Carlisle Companies Incorporated acquired Drexel Metals. This move turned an already strong player into an industry powerhouse, merging Drexel's innovative spirit with Carlisle's global reach. Today, Met-Fab by Drexel stands as a pinnacle of the Carlisle Construction Materials division, delivering high-performance, architecturally stunning metal roofing systems to demanding residential and commercial projects throughout Maryland and the surrounding regions.

Why Compatible Fall Protection Anchors Are Critical For Met-Fab Drexel Panels

Standing seam roofs from Met-Fab are sleek, durable, and built to withstand harsh environmental conditions. However, working on these high-performance systems requires specialized safety hardware that respects the roof's structural design.

Penetrating a Met-Fab roof to install fall protection is like buying a waterproof jacket and cutting holes in it. Met-Fab's panels are known for weathertight performance, but drilling into them creates immediate vulnerabilities. Puncturing the metal leads to leaks, rust, and structural degradation. Furthermore, penetrations almost certainly void your Drexel Metals manufacturer's warranty.

Non-penetrating anchors clamp securely to standing seams or roof peaks without penetrating the metal. They preserve the roof's integrity while providing OSHA-compliant tie-off points. Choosing non-penetrating hardware ensures your crew's safety and long-term roof performance.

By investing in compatible, non-penetrating anchors like the SSRA system, you prioritize worker safety while preserving the panels' pristine aesthetics and lifespan. This commitment to using the right tools for the right roof separates industry leaders from standard builders.

Proper Attachment: Set Screws and Torque Requirements

Your safety and the SSRA1 anchor's certified holding power depend on correct set screw application. We provide specialized fastening options based on the material gauge of your Met-Fab by Drexel panels:

• Cupped-Tip Stainless Steel Set Screws: Use these exclusively on 22-gauge steel panels. Torque them to 90 inch-pounds for a secure, non-destructive lock.
• Nylon-Tipped Set Screws: Apply these to 22- or 24-gauge steel panels to achieve certified holding power. Torque them to 180–200 inch-pounds for maximum strength.

Maintenance: Treat nylon tips as consumables. Replace them every 3 to 5 uses to ensure they maintain the necessary coefficient of friction.

CRITICAL WARNING: Never use an impact gun to install set screws. Over-torquing with an impact driver will crush the standing seam, damage the anchor hardware, and void the Drexel Metals warranty. Always use a calibrated torque wrench for final installation.

The SSRA Component System & Expansion Tools

The SSRA system is a professional-grade modular platform designed to adapt to the diverse needs of Met-Fab job sites:

• SSRA1 Seam Anchor: The foundation of the system. This patented, non-penetrating anchor provides a 5,000-pound certified tie-off point and is compatible with over 95% of today's standing seam profiles.
• SSRA2 Adjustable Roof Jack Adapter: Mounts directly to the SSRA1 to support 10-foot wooden walk-boards. These are fully adjustable to match the roof pitch and seam height, providing a level, stable work surface.
• SSRA3 Anchor Plates: These heavy-duty aluminum spanner plates connect two SSRA1 anchors and serve as the structural mounting interface for horizontal lifeline systems.
• 100-Foot SSRA Temporary HLL Kit: A complete, non-penetrating solution that includes the SSRA1 anchors and SSRA3 plates needed for a 100-foot lifeline. Restrict the use of horizontal lifeline systems to roof pitches of 4:12 or less.
• 120-Foot Super Anchor Permanent HLL Kit: Engineered for long-term maintenance, this kit provides a permanent horizontal safety installation. OSHA guidelines restrict compatibility to roof pitches of 4:12 or less.
• The Ridge Pro Steep Assist: The premier "First-Man-Up" tool for pitches between 6:12 and 12:12. This is the required choice for steep slope entry before connecting to seam-mounted anchors.

The Risk of Generic Imports vs. American-Made Reliability

Utilizing unbranded, imported, or generic "look-alike" anchors on a high-performance Met-Fab by Drexel system creates a massive legal and financial vulnerability for your business. Inspectors are increasingly targeting job sites for safety equipment that lacks verifiable, third-party test data. Because the SSRA1 is engineered, fabricated, and tested right here in the United States, we provide the comprehensive documentation you need to satisfy OSHA 1926.502 and ANSI standards. Overseas manufacturers often provide "self-certified" claims that crumble under legal scrutiny. Unlike these anonymous importers, we offer a dedicated American support staff ready to answer technical questions and assist with site-specific compliance.
