Product Description
What Is a 45° Angle Bracket?
A 45° angle bracket is a metallic connector designed to join two structural members at a 135° interior angle — the outside corner forms a clean 45° incline. In curtain wall and steel construction, not every joint is a right angle. Sloping facades, angled canopy beams, diagonal bracing, and architectural feature frames all demand non-orthogonal connectors that standard 90° brackets simply cannot provide.
Fabao Machinery fabricates 45° angle brackets in three key material groups to match every project condition: carbon steel for welded structural connections, stainless steel for exposed or corrosive environments, and aluminum alloy for lightweight curtain wall framing systems.
Material Selection Guide
| Material | Grade | Best For | Surface Treatment | Weldable? |
|---|---|---|---|---|
| Carbon Steel | Q235B | Heavy-duty welded connections to steel embed plates, canopy beams, bracing | Hot-dip galvanized (≥50μm), electro-galvanized, powder coated | Yes |
| Stainless Steel | SS304 / SS316 | Exposed architectural hardware, coastal & marine environments, hygienic areas | Pickled & passivated, optional powder coat | Yes |
| Aluminum Alloy | 6063-T5 | Aluminum curtain wall mullion-to-transom connections, non-welded framing, solar panel supports | Anodized (silver, black, bronze), powder coated | No (bolt-on) |
Typical Applications
-
Sloped Curtain Walls – Connecting inclined mullions to horizontal transoms at 45° joints.
-
Canopy & Awning Steel Beams – Bracing angled roof beams to vertical support columns.
-
Architectural Sunshades & Trellises – Geometric steel or aluminum frameworks requiring non-90° connections.
-
Diagonal Bracing Systems – Compression and tension tie-in points at 45° in steel structures.
-
Stone Cladding Subframes – Angled mounting brackets for entrance portals and feature walls.
-
Solar Panel Mounting Structures – Tilt brackets at custom angles for photovoltaic arrays.
