The Equal Leg Aluminium Angle Profile is one of the most fundamental yet versatile shapes in the aluminum extrusion catalog. With two legs of equal length forming a precise 90° corner, this L-profile delivers reliable structural support across countless industrial, architectural, and DIY applications. From heavy-duty equipment frames to edge protection trims, the equal leg angle combines simplicity of design with exceptional adaptability.

Manufactured from 6063-T5 or 6061-T6 architectural and structural grade aluminum, our equal angle profiles provide an outstanding strength-to-weight ratio, natural corrosion resistance, and excellent formability for secondary fabrication. The extrusion process ensures tight dimensional control — leg lengths, thickness, and the all-important 90° angle are held to tight tolerances across full production runs. This consistent geometry is critical when angles are used for alignment, framing, or jig components where squareness must be reliable.
Shengxin stocks and custom-produces a wide range of standard equal leg sizes, from small 10x10mm trim angles to large 150x150mm structural sections. Wall thickness can be specified from 1mm up to 15mm or more, depending on the load case. Beyond standard mill finish, we offer anodized aluminum profiles and powder coated surfaces for enhanced aesthetics and corrosion protection. Every batch is traceable back to the extrusion press, with mill certificates available upon request.
Features & Benefits
-
Precise 90° geometry: Equal leg angles are extruded with tight angular tolerance, ensuring reliable squareness for framing and structural connections — no need to shim or adjust on-site.
-
Wide standard size range: Leg lengths from 10mm to 150mm stocked; custom sizes up to 550mm profile width available. One supplier covers small trim and large structural sections.
-
Corrosion resistant without coating: Bare aluminum forms a natural oxide layer. For harsh environments, anodized or powder coated finishes add decades of protection without paint maintenance.
-
Easy to cut, drill & weld: 6063 and 6061 alloys accept standard metalworking tools. Angles can be mitered, drilled, tapped, or welded into complex frameworks with minimal preparation.
-
Lightweight handling: Aluminum angles are significantly lighter than steel equivalents — easier to transport, lift into place, and install, especially in overhead or access-restricted locations.
-
100% recyclable: All our aluminum angle profiles are fully recyclable at end of life, supporting circular economy and green building certification targets.

Typical Applications of Equal Leg Aluminium Angles
-
Structural framing & supports: Used as corner bracing, cross-bracing, and frame connectors in machine guards, conveyor systems, and workbench structures where steel would add unnecessary weight.
-
Edge protection & trim: Applied to protect the corners of walls, columns, and equipment housings. Also used as a clean finishing edge for tiling, paneling, and drywall corners in architectural interiors.
-
Brackets & mounting plates: Short cut pieces of angle serve as simple L-brackets for shelving, solar panel mounting, and electrical enclosure installation — easily drilled and bolted on-site.
-
Furniture & display systems: Powder coated angles form the structural legs and frames of modern retail displays, modular shelving units, and exhibition stands, combining aesthetics with load-bearing capacity.
-
Transportation & vehicle bodies: Aluminum extrusions like equal angles are used in trailer frames, truck bodies, and RV construction where corrosion resistance and weight savings are priorities.
-
Greenhouse & solar structures: Resistant to humid, UV-exposed environments without rusting, making equal angles ideal for greenhouse frames, solar module support rails, and agricultural infrastructure.

Why Shengxin for Equal Leg Aluminium Angle Profiles?
Standard aluminum angles are available from many suppliers, but few can match Shengxin’s combination of stock range, custom extrusion capability, and in-house fabrication. With 29 years of extrusion experience, we understand that a “simple” angle profile still demands precise die design, consistent alloy composition, and careful handling to arrive straight, square, and ready to use.
Extensive Die Library
With 500,000+ molds in stock, we likely already have the angle dimension you need — eliminating tooling costs and reducing lead times for standard profiles.
100,000-Ton Annual Capacity
35 extrusion lines (600–5500 tons) ensure we can handle both small batch orders and multi-ton contract volumes with reliable delivery schedules.
Complete Finishing Services
Anodizing (3 lines), powder coating (3 lines), PVDF, and wood grain transfer — all on-site. Your angles arrive finished and ready to install, not requiring secondary processing.
Precision Fabrication
Imported CNC machines for drilling, tapping, and mitering angles to exact lengths and hole patterns — we deliver parts, not just profiles, saving you workshop time.
Reliable Global Supply: $120 million total assets. 5,000-ton professional warehouse. 5 independent container loading platforms. We export aluminum angles to 97 countries with documentation support including mill certificates, packing lists, and certificate of origin for customs clearance.
Equal Leg Aluminium Angle Profile FAQ
Q: What is the difference between equal and unequal leg aluminum angles?
A: Equal leg angles have both legs the same length, forming a symmetrical L-shape. Unequal leg angles have one leg longer than the other, used when the load or attachment surface requires different bearing lengths on each side. We supply both types; this page focuses on equal leg profiles.
Q: Can I get aluminum angles cut to specific lengths and drilled?
A: Yes. Our fabrication shop provides cut-to-length, drilling, countersinking, and tapping services. Send your fabrication drawing, and we deliver ready-to-assemble angle components — no additional machining on your end.
Q: What alloy should I choose: 6063 or 6061?
A: 6063-T5 is ideal for architectural, trim, and general purpose applications where aesthetics and good corrosion resistance are key. 6061-T6 offers higher mechanical strength and is preferred for structural, load-bearing, and welded fabrications. If unsure, share your load conditions with our engineering team for a recommendation.
Q: Do you have a minimum order quantity for standard equal angles?
A: For stocked standard sizes, we are flexible with small quantities — you can order as little as a single 6-meter length for prototyping or trial. For custom die profiles, a minimum production run typically starts at 300–500 kg.
Q: Are Shengxin's aluminium angles suitable for outdoor use without coating?
A: Yes. Mill finish aluminum angles naturally resist corrosion through the formation of a protective oxide layer. For aggressive environments — coastal, industrial, or constant moisture — we recommend powder coated aluminum extrusions or anodized finishes for extended service life.
