Simpson Strong-Tie A35 Framing Angle
The A35 is an 18-gauge galvanized steel framing angle designed to adapt to multiple framing connections. Its exclusive bending slot enables instant, accurate field bends for both 2-way and 3-way ties. The reversible design allows mounting from either side, supporting a wide range of 90-degree wood-to-wood connections. Best for: contractors or DIYers needing flexible on-site adjustment for various framing layouts. Limitation: field bending requires proper technique to ensure consistent strength around bends.
Simpson Strong-Tie A34 Framing Angle
The A34 framing angle measures 1-7/16″ x 2-1/2″ in 18-gauge steel. It features a zinc (ZMAX) coating for corrosion resistance, making it suitable for outdoor framing and decorative outdoor connections. It includes pre-punched holes for straightforward installation with nails or screws. Best for: projects requiring reliable 90-degree joints with good outdoor longevity. Caution: ensure fasteners match the pre-punched pattern for secure anchoring.
Simpson Strong-Tie A35-100 Framing Angle
The A35-100 mirrors the A34 family’s features in a higher-volume pack. Crafted from heavy-duty 18-gauge steel with zinc galvanization, it supports a range of 90-degree connections and resists outdoor corrosion. Best for: shops or contractors who need multiple angles for rapid framing work. Caution: verify that the higher quantity pack aligns with project demand to avoid waste.
Simpson Strong-Tie A21Z 2 in. x 1-1/2 in. x 1-3/8 in. ZMAX Galvanized Angle
The A21Z provides a versatile 90° angle option with ZMAX galvanized coating for added corrosion resistance. It supports a range of joints and is positioned as a robust general connector for home repairs or moderate framing projects. Best for: users needing dependable, all-around angles for multiple 90-degree connections. Limitation: not designed for heavy hurricane ties or extreme load conditions.
18-Gauge Metal L-Shaped Right Angle Brackets
These basic 18-gauge galvanized brackets provide straightforward right-angle support for wooden frames and shelves. Best for: simple, cost-effective reinforcement in DIY projects or light-duty framing. Caution: limited to lighter loads; for structural framing, rely on purpose-built framing angles with pre-punched holes and higher load ratings.
Buying Guide: Key Purchase Considerations
- Material and coating: Choose 18-gauge galvanized steel for a balance of strength and corrosion resistance. ZMAX coating offers superior outdoor durability.
- Size and fit: Verify the dimensions (length, width, gauge) match your joint requirements and screw/nail patterns. Pre-punched holes speed up installation.
- Connection type: Decide between reversible/bendable angles (A35 family) or fixed-angle brackets (A21Z, A34) based on your layout.
- Environment: For exterior or damp conditions, prioritize corrosion-resistant finishes and larger load-capacity angles.
- Installation considerations: Some angles require field bending; ensure you have the right tools and technique to avoid compromising joint strength.
- Quantity planning: Packs vary from single items to bulk packs; choose according to project scale to minimize waste and cost.
FAQ
- What is 18-gauge galvanized steel best for in framing?
It provides moderate strength with good corrosion resistance for wood-to-wood joints and light-to-moderate loads. - When should I choose a reversible framing angle like the A35?
Choose when you need flexibility for multiple 90-degree connections from either side on the job site. - What’s the advantage of ZMAX coating?
It delivers enhanced corrosion resistance suitable for outdoor or moisture-prone environments. - Are pre-punched holes important for installation?
Yes, they speed up fastening and improve alignment, reducing adjustment time on site. - Can I use these angles for structural load-bearing applications?
Use only products rated for the loads in your design; consult a structural engineer for heavy-duty requirements. - How many angles should I buy for a project?
Base it on the number of joints and the anticipated need for replacements or future repairs; many projects overestimate by 10–20% to cover errors.
