Who Is A&S Building Systems?
Founded in 1958, A&S Building Systems initially operated in Houston, Texas, as a fabricator of grain storage bins before expanding into the design and fabrication of pre-engineered metal buildings (PEMB). In 1992, NCI Building Systems (now Cornerstone Building Brands) acquired A&S, positioning A&S as a premier subsidiary alongside industry leaders such as MBCI. Today, A&S operates a high-tech manufacturing facility in Caryville, Tennessee, where it produces complex, custom-designed metal building solutions for the industrial, commercial, and community sectors.
As a member of the Cornerstone family, A&S utilizes industry-leading standing seam technology. Their product lineup features high-performance profiles such as BattenLok HS, Double-Lok, and SuperLok. Every A&S roof system provides superior weather-tight performance and accommodates significant thermal movement through advanced "floating" clip systems. Contractors from the Tennessee Valley to across the United States rely on A&S for structural integrity and long-term reliability in demanding environments.
A&S Building Systems Require Non-Penetrating Fall Protection
Preserving the weather-tight integrity of an A&S roof requires safety hardware that respects the panel's movement. Many A&S standing seam systems use "floating" clips to manage thermal expansion across large spans. Using traditional anchors that penetrate the panel surface violates manufacturer specifications, causes hidden leaks, and voids the roof warranty. To maintain a secure seal, contractors must use specialized, non-penetrating anchors that clamp to the standing seams without piercing the metal.
The following products provide a complete safety solution for A&S Building Systems profiles:
- SSRA1 Seam Anchor: The foundational component. This patented, universal-fit anchor accommodates approximately 95% of today's standing-seam profiles, providing a certified 5,000-lb tie-off for non-curved 22-gauge and 24-gauge steel panels.
- SSRA2 Adjustable Roof Jack Adapters: Mount directly to the anchors to hold 10-foot wooden walk-boards for stable footing on steep slopes.
- SSRA3 Anchor Plates: High-strength spanner plates that connect two SSRA1 anchors to serve as structural endpoints for horizontal lifelines.
- 100-foot SSRA Horizontal Lifeline Kit: Allows two workers to move the entire length of the roof field while remaining 100 percent tied off on short-term projects.
- 120-foot Super Anchor Permanent HLL: A reliable, long-term maintenance solution using non-penetrating 5-inch riser posts that protect the roof's weather-tight seal.
- Ridge Pro Steep Assist: The essential First-Man-Up tool for pitches between 6:12 and 12:12, providing immediate tie-off before the worker leaves 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
To ensure certified holding power on A&S profiles, installers must select the appropriate fastener and torque setting based on the steel gauge:
- Cupped-Tip Stainless Steel Set Screws: Use these exclusively on 22-gauge steel and torque to 90 inch-pounds using a calibrated torque wrench.
- Nylon-Tipped Set Screws: Use these on 24-gauge steel. Testing proves that nylon tips provide a superior mechanical lock on lighter-gauge steel. 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 and ensure compliance with safety standards.
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.

Shielding Your Firm from Liability: The Risk of Generic Hardware
An A&S roofing system represents a significant capital investment in structural engineering and thermal efficiency. Your fall protection hardware should reflect that same level of professionalism. Using unbranded, imported, or generic anchors creates a significant legal and financial risk for your business. Regulatory inspectors are increasingly seeking safety equipment that includes verifiable third-party test data. Failing to provide documentation of compliance with OSHA 1926.502 and ANSI standards can result in immediate site shutdowns.
Beyond the fines, these incidents damage your safety rating and bonding capacity. If a roof anchor lacks a third-party paper trail, domestic technical support, or certified test reports, it is an unacceptable liability that has no place on a professional job site. American-made SSRA hardware provides the traceable reliability required for industrial-scale building envelopes. Review our full independent laboratory test reports to verify compliance.

10 Critical Safety Rules for A&S and MBCI Projects
- Protect First-Man-Up Workers: On pitches between 6:12 and 12:12, ensure workers use The Ridge Pro before stepping onto the panel surface. This tool protects the worker during the critical transition from the ladder to the peak.
- Conduct Daily Torque Verification: Users must verify set-screw torque before each attachment to confirm that the anchors meet required specifications and that no tampering or improper installation has occurred.
- Eliminate Clip-Location Guesswork: Traditional anchors require you to find hidden clips beneath the panel for a secure hold. The SSRA1 secures directly to the seam itself, providing a certified 5,000-pound anchor point regardless of clip location.
- Reject Uncertified Anchors: Do not risk your company's future on unbranded anchors. If a device lacks a verifiable third-party test report for compliance with OSHA 1926.502, it poses a liability risk that could cost you $100,000 in fines.
- Minimize the Pendulum Risk: Always account for dynamic sag. Limit the work area to a 30-degree arc from the anchor point to prevent dangerous swing falls that could result in collisions with the ground or the building.
- Thermal Expansion Is Critical: A&S panels expand and contract with temperature changes. Only use non-penetrating seam clamps that allow for this natural movement, preventing buckling or "oil-canning" of the steel.
- Avoid Metal Incompatibility: Galvanic corrosion can cause a roof to fail. Ensure you use only Stainless Steel set screws on steel panels to prevent galvanic reactions that cause rust and structural weakness.
- Prepare for Rescue: Fall arrest is only half the battle. Equip all harnesses with trauma relief straps to prevent suspension trauma while workers wait for rescue teams.
- Prioritize Low-Torque Anchor Designs: High-torque, two-piece clamps can easily crush a standing seam, voiding the panel warranty. The SSRA1 low-torque design requires only 90 inch-pounds (for 22-gauge) to achieve a full-strength, non-destructive lock.
- Verify Material Gauge: Before installation, confirm the metal thickness. Many architectural profiles, such as Slimline or LokSeam, may be available in 26-gauge or thinner and are not compatible with seam-mounted anchors, requiring ridge-mounted protection instead.
