System overview
The RM-EDGE™ G3200-TM is an architectural welded aluminum and glass guard system featuring integrated glass capture for balcony and terrace applications.
Welded aluminum structural assemblies, tempered glass set within aluminum glass channels and a continuous architectural handrail profile suit residential and commercial developments across low-, mid- and high-rise construction.
Configuration
- Welded aluminum glass guard system for top-mounted balcony and terrace applications
- Structural aluminum posts (1½" × 2½" standard) with 2½" square corner post assemblies
- Shop-welded post and base assemblies fabricated under controlled manufacturing conditions
- Fixed, rigid system once installed and secured
- Tempered glass infill panels in thicknesses as required by project design
- Suitable for high-rise, mid-rise and low-rise buildings
Materials
- Weld-appropriate aluminum structural components (6061-T6, 6005A-T6 / 6063-T6)
- Continuous architectural handrail extrusion with integrated glass capture
- Tempered glass infill
- Stainless steel fasteners and concealed setting hardware
- Isolation materials used to prevent galvanic interaction
Fabrication
- Shop-welded assemblies produced under controlled fabrication procedures
- Welded base and post assemblies designed to maintain panel rigidity and alignment
- Adjustment features incorporated to accommodate slab tolerances and façade variation
- Post-weld surface preparation completed prior to finishing
Mounting & anchorage
- Surface mounted to structural slab
- Anchorage engineered per project loading requirements
- Mechanical anchors or threaded rod anchorage systems utilized
- System coordinated with waterproofing and drainage strategies
- Base assemblies distribute loads along slab edge

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™ G3200-TM (Architectural Adjustable Top-Mounted 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: Top-mounted (surface-mounted) to structural slab. 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.
