Simpson HL57PC Heavy L-Angle is a structural heavy angle from Simpson's Decorative Hardware line, purpose-built to help connect timber members and reinforce right-angle connections in exposed wood applications. Fabricated from 7-gauge steel with a black powder-coat finish, it bridges the gap between structural performance and finished appearance, making it a practical choice for timber framing and heavy wood construction where connectors remain visible. Compatible with Simpson Strong-Tie structural hardware, this heavy angle supports standardization and construction economy on projects that demand both reliability and a refined look.

Key Features

• Helps connect timber and reinforce right-angle connections - provides a rigid, load-bearing joint at timber intersections, reducing movement and improving overall structural integrity in heavy wood framing.
• Resists uplift and diagonal forces in wood connections - engineered to handle multiple force directions at the joint, so the connection holds up under real-world loading conditions, not just vertical loads.
• Made from 7-gauge steel - the heavy gauge construction delivers the thickness and strength needed for timber-scale connections where lighter connectors would be undersized.
• Black powder-coat finish - a pre-applied decorative finish that keeps the connector looking intentional and clean in exposed applications, eliminating the need for field painting or concealment.
• Part of the Simpson Decorative Hardware line - designed alongside other aesthetically finished connectors, making it straightforward to maintain a consistent look across an entire timber framing project.

Why This Product

• Structural strength with a finished appearance - the black powder-coat surface means this heavy angle works as a design element rather than an eyesore, ideal for exposed timber framing in architectural or residential applications where hardware is part of the visual outcome.
• Built for timber-scale connections - the 7-gauge steel construction and generous sizing address the demands of heavy wood joinery, giving builders and contractors a connector appropriately matched to the loads and member sizes common in timber framing.
• Multi-directional force resistance - by resisting both uplift and diagonal forces, this heavy angle secures the joint against the range of stresses a right-angle timber connection can experience, offering broader protection than connectors rated for a single load direction.
• Compatible with Simpson Strong-Tie structural hardware - fits within an established ecosystem of connectors, so it can be incorporated into projects already using Simpson hardware without compatibility concerns or mixed-system compromises.
