System overview
The RM-EDGE™ G3300-TM is a premium welded aluminum and glass guard system featuring a slim structural post profile and integrated glass capture at the handrail to achieve maximum transparency and refined architectural appearance.
The system incorporates adjustable installation capability while maintaining a rigid welded structural frame, suiting high-performance residential and commercial balcony applications.
Designed for projects requiring minimal visual mass, precise alignment and consistent façade presentation.
Configuration
- Welded aluminum glass guard system for top-mounted balcony and terrace applications
- Structural aluminum 1½" slim post assembly for reduced visual obstruction
- Continuous extruded aluminum handrail profile designed to receive and capture the top edge of glass panels, eliminating the need for a separate glass channel
- Integrated adjustment capability to accommodate slab variation and ensure consistent guard elevation
- Shop-welded post and base assemblies fabricated under controlled manufacturing conditions
- Fixed, rigid system once installation and adjustment are completed
- Laminated safety 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)
- Architectural handrail extrusion with integrated glass capture
- Tempered laminated safety glass infill
- Stainless steel fasteners and concealed setting hardware
- Isolation materials to prevent galvanic interaction
Fabrication
- All aluminum welding performed under controlled shop conditions in accordance with AWS D1.2 Structural Welding Code — Aluminum
- No field welding of structural aluminum components permitted
- Welded assemblies designed to maintain structural continuity and panel rigidity
- Fabrication tolerances maintained for glass alignment and façade consistency
- Post-weld preparation completed prior to finishing
Mounting & anchorage
- Surface mounted to structural slab
- Anchorage engineered based on project loading requirements
- Mechanical anchors or threaded rod systems utilized
- Adjustment capability accommodates slab variation without compromising performance
- Waterproofing coordination maintained
Performance & code compliance
