Buyers who source
aluminum corner profiles usually need three things: the right shape, a consistent finish, and a supplier who delivers on schedule. Corner profiles, also called aluminum angles or L profiles, protect edges, join panels and add support in many products. A small change in thickness, leg length or surface finish can change cost, fit and appearance.
Aluvoltec is an aluminum extrusion manufacturer in the Sihanoukville Special Economic Zone, Cambodia. We extrude, finish and machine custom aluminum profiles for industries such as construction, solar, automotive and ladders. This guide explains what to check when you buy
aluminum corner profiles, from sizes and alloys to finishes, MOQ and quality control. Use it to prepare a clear inquiry and compare suppliers with confidence.
Aluminum Corner Profiles Manufactured in Cambodia
Aluvoltec produces
aluminum corner profiles at its own plant in Cambodia. The facility runs 8 extrusion machines and 2 anodizing lines, and it also offers fabrication and machining. Keeping extrusion, surface finishing and machining in one place means fewer handovers between vendors. You deal with one team for quality, schedule and packaging.
Our team has more than 20 years of experience in aluminum extrusion. Our service is built for importers, distributors, OEM buyers, project contractors and factory purchasing teams that need stable quality and repeat supply.
Equal and Unequal Aluminum Corner Profile Sizes
Aluminum corner profiles come in two basic forms. Choose the one that matches how the part will be used.
Equal-leg corner profiles
Both legs have the same length, for example 25 × 25 mm. Buyers use them for frames, edge protection, trim and general support.
Unequal-leg corner profiles
The legs have different lengths, for example 30 × 20 mm. They suit steps, shelves and panel edges where one leg must cover more surface.
For either type, define leg A, leg B, wall thickness, length and corner radius. Buyers often combine corner profiles with other shapes such as aluminum channels, T profiles, Z profiles, H bars, flat bars, square bars, square tubes, round tubes and round rods. See our range of
standard aluminum profiles and ask whether a mixed order fits your project.
Anodized Aluminum Corner Profiles: Colors and Finishes
Anodizing builds a hard oxide layer on the aluminum surface. It improves corrosion and wear resistance and keeps the metallic look. Aluvoltec operates its own anodizing lines, so finishing is part of the same production flow as extrusion.
• Higher surface hardness than mill finish
• Good resistance to weather and regular cleaning
• Natural silver or dyed colors, depending on the process
• A durable surface with no paint layer that can peel
Many architectural projects use an anodic layer of roughly 10 to 20 microns. Confirm the thickness your project needs. For color-critical orders, send a reference sample and request that the full quantity is anodized in one batch where possible. This limits shade differences between lots.
Custom Aluminum Corner Profiles to Your Drawing
Standard sizes do not always fit. Custom
aluminum corner profiles let you control the cross-section, wall thickness, radius and extra features such as grooves or screw ports. A typical custom project follows four steps:
1. Send your drawing or a physical sample.
2. Our team reviews the design for extrusion feasibility and suggests changes if needed.
3. Confirm tooling, alloy, finish and sample approval.
4. Start production and agree on packing and shipping.
Share your expected volume and the end use as well. This helps us recommend the right alloy, wall thickness and finish.

To estimate weight, multiply the cross-section area in mm² by 0.0027. The result is the approximate weight in kg per meter. This uses an aluminum density of 2.7 g/cm³.
Which Aluminum Alloy Is Best for Corner Profiles? (6060 vs 6063)
There is no single answer. Both 6060 and 6063 belong to the Al-Mg-Si family. Both extrude well and take anodizing well. Their properties are close, so most buyers decide by the standard named in their specification.
•
6060: common in projects that follow European (EN) standards. Suits general-purpose trim, frames and furniture parts.
•
6063: common in projects that follow North American (AA/ASTM) standards. Popular for architectural and decorative parts that need a clean anodized surface.
For load-bearing use, ask for a stronger temper such as T6 and run your own design check. Tell us your target standard, and we will confirm the alloy and temper we can supply.
Aluminum Corner Profile Applications: Construction, Furniture, Solar, Automotive
Aluminum is light, resists corrosion and is easy to cut and finish. These traits make
aluminum corner profiles useful across many sectors.
Construction
Contractors use corner profiles for edge trim, framing, tile and panel finishing, and support brackets. Browse our
construction profiles for related products.
Furniture and interiors
Designers use anodized corners to protect cabinet, shelf and display edges. The clean metal finish suits modern interiors.
Solar
Installers use aluminum angles in mounting structures and brackets. Aluvoltec also produces solar aluminum frames for photovoltaic projects.
Automotive and industrial
Corner profiles also serve as trim, supports and framing parts in vehicles and machines. For equipment frames and machine builds, see our
industrial aluminum profiles.
Powder Coated, Mill Finish and Brushed Corner Profile Options
The right finish depends on appearance, budget and the environment. These are the main options for
aluminum corner profiles:
•
Mill finish: the raw extruded surface. It has the lowest cost and suits parts that will be painted, bonded or hidden.
•
Powder coated: offers many colors and textures. It works well when you need to match a project color scheme.
•
Brushed: a fine linear grain that hides small marks and gives a soft, modern look.
•
Anodized: a hard, integrated oxide layer, as described above.
Tell us whether the parts will be used indoors, outdoors or near the coast. Harsher environments usually call for a higher grade of surface protection.
CNC Machining, Cutting and Fabrication Services
Many buyers want parts that are ready to assemble, not only raw bars. Aluvoltec machines custom aluminum profiles in house. Typical work includes:
• Cutting to fixed lengths
• Drilling and punching holes
• CNC milling and notching
• Deburring and surface finishing
Machined parts reduce your own processing cost and simplify your supply chain. Confirm the exact process range and tolerance for your part when you send the drawing.

Supplier checklist for importers
Before you place an order with any supplier, ask these questions:
• Which alloy and temper will you supply?
• How do you inspect dimensions and surface quality?
• What are the MOQ and lead time for my profile?
• How do you pack for sea freight?
• Can you support custom drawings and machining?
Minimum Order Quantity, Lead Time and Packaging
MOQ and lead time depend on the profile, alloy, finish and whether tooling already exists. We do not publish a fixed number, because a standard size and a new custom profile are very different jobs. Send your drawing and target quantity, and we will reply with clear terms.
Good packaging protects the surface finish in transit. Common options for aluminum profiles include protective film, paper interleaving, plastic wrap, bundles and wooden pallets or crates. Tell us your destination port and loading plan so we can suggest suitable packing.
Quality Control and Testing for Aluminum Extrusions
Quality problems often appear late, at the customer's site. Clear inspection rules prevent them. For aluminum extrusions, buyers commonly check:
• Dimensions and straightness against the drawing
• Wall thickness and corner radius
• Surface defects such as scratches, die lines and color variation
• Anodic layer thickness for anodized parts
• Alloy and temper
Tell us which standards and test documents your market requires, such as inspection reports or material certificates. We will confirm what we can provide before you place an order.
Aluminum Angle vs. Corner Profile: What Is the Difference?
Many buyers use the two terms for the same product, and in extrusion practice they overlap. The difference is mostly in how the part is used.
•
Aluminum angle: the general name for an L-shaped section with two legs, equal or unequal. It is common in structures and supports.
•
Aluminum corner profile: a name often used when the part protects or finishes a corner or edge. It may include a decorative radius or extra features.
If your design needs a U-shaped section instead of an L shape, look at our
aluminum channel profiles. When you are unsure, send a sketch and we will help you choose the right section.
