ALUS Double, Triple, Quad Hangers — Custom-Die Designed for Maximum Load Value
The ALUS series joist hangers are custom-die designed and manufactured by Tamlyn for quick installation and maximum allowable load performance. Constructed from 18-gauge galvanized steel, these hangers are available in G-185 Triple Zinc or Hot-Dip Galvanized finishes to suit corrosion-resistance requirements on the jobsite. Designed for use with wood or structural composite lumber having an effective specific gravity of 0.55 or greater — such as Southern Pine — the ALUS series carries both FL and ICC code approvals, making them suitable for regulated residential and commercial framing applications. Contractors working on double, triple, or quad joist assemblies will find these hangers engineered to deliver reliable gravity and uplift load performance across standard load duration conditions.

Unlike generic off-the-shelf joist hangers, the ALUS series is custom-die designed by Tamlyn specifically to optimize both installation speed and load capacity. The dual finish options — G-185 Triple Zinc and Hot-Dip Galvanized — give contractors the flexibility to match corrosion-protection requirements for different exposure conditions, and the dual ICC and FL code approvals simplify the inspection and permitting process on regulated projects.
Key Features & Benefits
Custom-Die Design for Quick Installation
Tamlyn engineered the ALUS hangers with a custom die to streamline field installation. Faster hanger placement reduces labor time on multi-joist assemblies, keeping framing crews on schedule.
18-Gauge Galvanized Steel Construction
The 18-gauge steel provides the structural rigidity needed to achieve rated allowable loads in double, triple, and quad joist configurations. Galvanized construction protects against corrosion in typical framing environments.
Dual Finish Availability — G-185 Triple Zinc or Hot-Dip Galvanized
Contractors can specify the appropriate corrosion-resistance level for the project's exposure conditions. Hot-Dip Galvanized is available for applications requiring a heavier zinc coating; call for availability on specific finishes.
FL and ICC Code Approvals
The ALUS series carries FL Approval #8283 and ICC approvals ESR-1347 and ER-2556, providing the documentation needed to satisfy inspectors and meet code requirements on permitted projects without additional engineering submittals.
Load Duration Factor Flexibility
Allowable gravity loads are rated at three load duration factors — C = 1.0, 1.15, and 1.25 — covering occupancy live loads, snow loads, and construction loads respectively. Uplift loads are adjusted at C = 1.6 for wind and seismic conditions, giving engineers and contractors the data needed for accurate load calculations without further increases permitted.
Common Applications
Double Joist Framing
The ALUS series is designed for double joist assemblies where increased load capacity is required at beam-to-header connections in floor and roof framing.
Triple Joist Assemblies
Used where triple joist members are specified to carry concentrated loads, such as at stair openings, large floor openings, or heavily loaded beam points.
Quad Joist Connections
Supports quad joist configurations in high-load framing situations, providing a code-approved connection at the header without custom fabrication.
Southern Pine and High-Specific-Gravity Lumber Framing
Rated for use with wood or structural composite lumber having an effective specific gravity of 0.55 or greater, making these hangers well-suited for Southern Pine framing common in southeastern U.S. construction.

Frequently Asked Questions
Q: What lumber types are compatible with the ALUS hangers?
A: The ALUS hangers are rated for use with wood or structural composite lumber having an effective specific gravity of 0.55 or greater, such as Southern Pine. They are not rated for use with lower-density lumber species that fall below this specific gravity threshold.
Q: What code approvals does the ALUS series carry?
A: The ALUS series holds FL Approval #8283 and ICC approvals ESR-1347 and ER-2556, supporting use on code-regulated residential and commercial projects.
Q: What finish options are available, and how do I order a specific finish?
A: The ALUS hangers are available in G-185 Triple Zinc or Hot-Dip Galvanized finishes. Availability varies by finish — contact Tamlyn directly to confirm which finish is in stock for your order.
Q: What are the allowable gravity loads for the ALUS26-2 at different load durations?
A: For the ALUS26-2, the allowable joist load is 935 LBF at all three load duration factors: C = 1.0 (occupancy live loads), C = 1.15 (snow loads), and C = 1.25 (construction loads). No further increases in allowable loads are permitted beyond these values.
Q: How many nails are required to achieve the rated load on the ALUS26-2?
A: The ALUS26-2 nail schedule requires 4 nails into the joist and 8 nails into the header to achieve the rated allowable loads.
Q: What gauge steel are these hangers made from?
A: The ALUS hangers are manufactured from 18-gauge galvanized steel.
