Proper mechanical installation of the Wallpro SF-82-CG heavy-duty extruded EPDM corner and column guard ensures long-term impact absorption and edge protection in high-traffic commercial and industrial facilities. Featuring an 82 mm (W) x 82 mm (H) x 16 mm profile with an integrated 5 mm internal supporting beam, the guard is engineered for direct surface mounting onto standard 90-degree corners across concrete pillars, structural masonry, and interior or exterior wall edges.
Substrate Compatibility and Preparation
The SF-82-CG profile is designed for installation on structural substrates in multi-level parking structures, basement garages, loading docks, healthcare corridors, airports, hotels, schools, office complexes, and residential developments. Compatible substrates include:
- Square and rectangular cast-in-place structural concrete columns
- Solid concrete masonry units (CMU) and structural brick pillars
- 90-degree wall corners in commercial corridors and loading zones
Prior to mounting, the corner surface must be cleared of loose concrete aggregate, dust, moisture, and surface contaminants. Ensure that the 90-degree corner profile is structurally sound to provide adequate holding power for mechanical anchoring hardware.
Mechanical Fastening with 6 mm Steel Anchor Fasteners
The Wallpro SF-82-CG is secured using 6 mm steel anchor fasteners to deliver rigid impact resistance against vehicle contact. The mechanical fixing process is conducted as follows:
- Profile Alignment: Position the 82 mm x 82 mm EPDM guard vertically against the 90-degree column apex, ensuring the 5 mm internal supporting beam sits flush against the corner.
- Hole Marking & Drilling: Mark fastener points along the mounting line. Drill pilot holes into the structural concrete or masonry using a drill bit sized appropriately for 6 mm steel anchors.
- Debris Removal: Clear dust and masonry debris from drilled holes to ensure full engagement and grip depth for the steel anchors.
- Fastener Tightening: Insert the 6 mm steel anchor fasteners through the profile into the substrate. Tighten evenly to secure the 3 mm outer wall and internal supporting beam firmly against the column, avoiding over-compression of the 70 ± 5 Shore A hardness EPDM elastomer.
Reflective Strip Positioning and Optical Alignment
The top face of the profile integrates dual 18 mm PVC reflective warning strips designed to increase visibility for approaching motorists and equipment operators. When mounting the guard, align the profile so that both 18 mm PVC reflective strips face oncoming vehicular traffic paths. Ensure that mechanical fasteners do not interfere with or puncture the dual reflective inserts during installation.
Post-Installation Verification and Maintenance
After mechanical fastening is complete, conduct a thorough site verification:
- Confirm that the 82 mm x 82 mm guard is seated tight along the entire vertical column edge without bowing or gaps.
- Verify that all 6 mm steel anchor fasteners are securely torqued and seated flush.
- Inspect the dual 18 mm PVC reflective strips to ensure clean, unobstructed optical reflectivity.
- Maintain the surface through routine washdowns using water and standard commercial cleaning agents, leveraging the non-porous, UV- and ozone-resistant EPDM material properties (tested to ASTM D414 and ASTM D1149 standards).
- Implement periodic facility checks to inspect fastener tightness and surface integrity following vehicle impact events.
