RM-EDGE™ G3100-FM
Face-Mounted Welded Glass Railing System
The G3100 assembly anchored to the slab edge instead of the top of it. The full balcony area is kept, and no anchors pass through the walking surface.

System overview
The RM-EDGE™ G3100-FM is a shop-fabricated welded aluminum and glass guard system designed for slab-edge and façade-mounted applications where top mounting is not feasible, or where architectural intent requires a clear walking surface.
Welded aluminum post and rail assemblies combine with laminated safety glass infill to provide unobstructed views, efficient load transfer to the structural edge and consistent architectural appearance.
Configuration
- Face-mounted welded aluminum guard assembly
- Shop-welded post and rail framework fabricated under controlled conditions
- Laminated tempered safety glass infill
- Modular prefabricated panels for consistent installation
- Custom widths, heights and glass thickness configurations available
- Designed for balconies, terraces and retrofit slab-edge conditions
Materials
- Welded structural components fabricated from weld-appropriate aluminum alloys including 6061-T6, 6005A-T6 and 6063-T6
- Tempered laminated safety glass infill
- Stainless steel fasteners and concealed connection hardware
- Isolation materials incorporated to prevent galvanic interaction and moisture intrusion
Fabrication
- Shop welding performed under controlled fabrication procedures
- Welded joints designed to maintain panel rigidity and structural continuity
- Fabrication tolerances maintained for glass alignment and façade interface
- Post-weld preparation completed prior to architectural finishing
Mounting & anchorage
- Face mounted to slab edge, steel framing or embedded structural plates
- Anchorage engineered to transfer guard loads directly into primary structure
- Mechanical anchors, threaded rod systems or structural fastening methods used as required
- System allows coordination with waterproofing membranes and façade assemblies
- Load path designed to minimize slab penetration at walking surface
Performance & code compliance
Designed to meet or exceed:
- Ontario Building Code guard load provisions (OBC 4.1.5.14)
- CSA S157 aluminum design requirements
- OBC SB-13 “Glass in Guards”
- Applicable ASTM safety glazing standards
- Engineering review of welded assembly and anchorage
Finish options
- Factory powder-coat and Duracron, Acrynar, Duranar (XL) finishes meeting AAMA 2603, AAMA 2604 or AAMA 2605
- Standard and custom architectural colors available
- Textured and matte finishes supported
- Anodized finishes available upon request
Applications & advantages
Typical applications
- High-rise slab-edge balconies
- Retrofit balcony replacement
- Podium edges
- Projects requiring clear walking surface
- Hospitality and luxury residential developments
- Façade-integrated guard systems
Advantages
- Preserves balcony usable area
- Continuous welded panel rigidity
- Clean slab edge appearance
- Reduced waterproofing penetrations at walking surface
- Compatible with multiple glass thickness options
- Efficient prefabricated installation
- Consistent architectural elevation

Ready to paste into Section 05 73 00 (Decorative Metal Railings) or the guard schedule. Project-specific values (glass thickness, guard height, color) are left for the specifier to complete.
Guard system: RM-EDGE™ G3100-FM (Face-Mounted Welded Glass Railing System), as manufactured by Railing Masters Inc., 110 Claireport Crescent, Unit 4, Etobicoke, Ontario.
Fabrication: Shop-welded aluminum post and rail assemblies fabricated under controlled conditions in accordance with AWS D1.2; no field welding of structural aluminum components.
Materials: Structural components of weld-appropriate aluminum alloys (6061-T6, 6005A-T6, 6063-T6); stainless steel fasteners and concealed hardware; isolation materials at all dissimilar-metal interfaces. Extrusions supplied by certified North American manufacturers with mill certification available.
Infill: Tempered laminated safety glass infill in thickness per project design, conforming to OBC SB-13 "Glass in Guards" and applicable ASTM safety glazing standards.
Mounting and anchorage: Face-mounted to structural slab edge, steel framing or embedded plates. Anchorage engineered to project loading requirements; shop drawings showing anchorage layout and panel configuration to be submitted for review.
Performance: Designed to meet or exceed Ontario Building Code guard load provisions (OBC 4.1.5.14) and CSA S157 aluminum structural design.
Finish: Factory-applied powder coat, Duracron, Acrynar or Duranar (XL) coating to AAMA 2603, 2604 or 2605 as scheduled; color per architect's selection.
