GIGANT Concealed Beam Hangers for Heavy Timber Construction 61

GIGANT concealed beam hangers are high capacity structural connectors engineered for heavy timber, log construction, and mass timber applications. Designed for main to secondary beam connections, these concealed steel connectors provide immediate load transfer, precise alignment, and long term joint compression in demanding structural environments.

This category includes GIGANT beam hangers with a 40 mm connector depth, covering sizes such as 120 × 40, 150 × 40, and 180 × 40. All connectors in this group share the same concealed engagement principle, installation method, and performance characteristics.

Engineered Concealed Beam Hanger System

Each GIGANT connector consists of two identical steel brackets that interlock through a dovetail like engagement. One bracket is recessed into the primary timber member, while the mating bracket mounts directly to the secondary beam using KNAPP SK screws.

The short hooking path allows the secondary beam to slide into position with minimal insertion travel. Once engaged, the connector becomes immediately load bearing, and the self tensioning geometry maintains continuous joint compression over time.

Key Performance Features

• High load concealed beam hangers for heavy timber connections
• 40 mm connector depth across all sizes in this category
• Short hooking path enables fast drop in assembly
• Self tightening design maintains long term joint compression
• Immediately load bearing once engaged
• Suitable for glulam, solid timber, mass timber, and log construction
• Compatible with timber to timber, timber to steel, and timber to concrete supports
• Fire resistance performance when installed fully concealed
• Allows disassembly and reassembly when required
• Available in blue galvanized or hot dip galvanized finishes

Structural Capacity and Compliance

GIGANT concealed beam hangers are engineered for high strength structural applications and are approved under ETA 10/0189 when installed using original KNAPP SK screws. Characteristic load capacities vary by connector size and are verified based on C24 timber.

When installed fully concealed, the system supports fire resistance requirements for structural timber connections, including R30 and R60 assemblies depending on cover depth and installation geometry.

Applications

GIGANT concealed beam hangers are used across a wide range of structural timber projects, including:

• Glulam beam to beam connections
• Heavy timber and mass timber structures
• Timber frame and hybrid construction
• Log home construction
• Pergolas, canopies, gazebos, and sunrooms
• Commercial and architectural timber buildings

Installation and Accessories

Installation can be performed using CNC machining or guided on site tooling to ensure consistent accuracy and repeatable performance. The connector engages with minimal insertion travel and requires no additional adjustment once seated.

Optional accessories are available to enhance installation accuracy and connection security:

• GIGANT Locking Clip for securing the connection against pull out forces
• GIGANT Drilling Jig for precise and repeatable screw positioning
• GIGANT 40 mm drilling templates for accurate on site layout
• MULTI F 40 routing jig for producing consistent recessed housings
