System overview
The RM-EDGE™ G3100-TM is a shop-fabricated welded aluminum and glass guard system designed to provide unobstructed views and continuous structural performance for exterior guard applications.
The system combines welded aluminum posts and rail assemblies with laminated safety glass infill to deliver architectural clarity, durability and reliable load transfer across residential, commercial and hospitality projects.
Configuration
- Top-mounted welded aluminum guard assembly
- Shop-welded post and rail framework fabricated under controlled conditions
- Laminated tempered safety glass infill
- Modular panel fabrication for consistent alignment and quality
- Custom widths, heights and glass configurations available
- Designed for balconies, terraces and podium applications
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 hardware
- Isolation materials incorporated to prevent galvanic interaction
Fabrication
- Shop welding performed under controlled fabrication procedures
- Welded joints designed to provide structural continuity and panel rigidity
- Fabrication tolerances maintained to ensure glass alignment and consistent installation
- Post-weld finishing prepared for architectural coating systems
Mounting & anchorage
- Surface mounted to structural slab or substrate
- Anchorage engineered based on project loading requirements
- Mechanical anchors or threaded rod systems used to transfer guard loads to primary structure
- System accommodates waterproofing coordination and drainage provisions
- Base assemblies distribute loads along slab edge
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”
