The Simpson Heavy L-Angle in hot-dip galvanized 7-gauge steel is a heavy-duty right-angle connector engineered by Simpson to reinforce timber framing joints and structural wood connections where both strength and durability are critical. Designed to handle the real-world demands of construction, this connector resists uplift and diagonal forces while delivering the corrosion protection required for exterior environments and treated-wood applications - making it a go-to choice for engineers and contractors who need reliable, code-compliant hardware. Compatible with Simpson structural hardware, it promotes standardization and construction economy across a wide range of framing and timber projects.

Key Features

• Reinforces right-angle timber connections - provides a rigid, secure joint where structural members meet at 90 deg., reducing movement and maintaining alignment under load
• Resists uplift and diagonal forces - engineered to counter the real stresses that act on wood connections, helping protect structural integrity over time
• Heavy 7-gauge steel construction - the substantial material thickness delivers the load capacity and rigidity that heavy framing and timber applications demand
• Hot-dip galvanized finish - the HDG coating provides extra corrosion resistance compared to standard finishes, making this angle well suited for exterior use and contact with treated wood where moisture exposure is a concern
• Installs with 1/2 in. diameter bolts - designed for bolt-driven installation, ensuring a firm, secure connection between structural members
• Compatible with Simpson structural hardware - works alongside other Simpson connectors to support a consistent, standardized approach to framing and timber construction

Why This Product

• Built for demanding exterior and treated-wood environments - the hot-dip galvanized coating offers a higher level of corrosion protection than standard coatings, so this heavy angle holds up where lesser connectors would degrade over time
• Heavy-gauge steel for serious structural work - 7-gauge construction means this connector is sized and rated for timber framing and other heavy-duty right-angle connections, not light-duty general carpentry
• Engineered and tested by Simpson - manufactured to the quality standards that engineers and contractors rely on, giving confidence that the connector will perform as expected in structural applications
• Promotes jobsite efficiency and standardization - versatile design works across a range of timber and framing connections and pairs with other Simpson structural hardware, reducing the need for custom fabrication and simplifying procurement

Frequently Asked Questions

What type of steel and thickness is the HL55HDG made from?

The HL55HDG is manufactured from 7-gauge steel, providing the heavy-duty structural integrity required for demanding timber and framing connections.

What makes the hot-dip galvanized coating on the HL55HDG beneficial?

Hot-dip galvanization (HDG) offers extra corrosion resistance compared to standard finishes, making the HL55HDG well suited for exterior applications and use with treated wood where exposure to moisture and corrosive elements is a concern.

What hardware is recommended for installing the HL55HDG?

The HL55HDG should be installed with 1/2 in. diameter bolts, ensuring a secure and code-compliant connection between structural members.

What types of forces does the HL55HDG resist in a wood connection?

The HL55HDG is engineered to resist uplift and diagonal forces in wood connections, helping to maintain the integrity of right-angle joints under a variety of structural loads.
