Unequal angle metal — is one of the most versatile and popular types of rolled metal. Despite the simplicity of the design, such a profile is used in dozens of industries — from construction to mechanical engineering. In this article, we will tell you in detail, what is an unequal angle, where it is used, what sizes and materials exist, and why it is profitable to order metal products from the angle from the company Art-Metal.
🔧 What is an unequal angle?
Unequal angle — is a metal profile of an L-shape with two shelves of different widths, connected at a right angle. It is made of steel (regular carbon, galvanized, stainless), aluminum or other metals by hot or cold rolling.
📏 Example of dimensions: 63×40×5 mm, where the first number is the width of the long shelf, the second is the short one, and the third is the thickness of the metal.
⚙️ Key features of unequal angle
-
📐 Asymmetry of shelves allows the element to be used in specific designs
-
💪 High flexural and compressive strength
-
🛠️ Convenient installation and welding
-
🔩 Possibility of use as an independent load-bearing element
-
🌧️ Corrosion resistance (when using stainless or galvanized steel)
🏗️ Where are unequal angles used?
The application of unequal angle is extremely diverse. The main industries and specific applications are presented below.
🧱 1. Construction and architecture
Corners are used as:
-
elements frame structures
-
column amplifiers, beams and ceilings
-
connecting nodes during installation of metal structures
-
frames for windows and doors
-
decorative elements of facades
-
during assembly awnings, canopies, verandas
📌 Advantage: unequal-angles are ideal where rigidity in one plane and compactness in another are required.
🚛 2. Mechanical engineering and automotive industry
-
Manufacturing frames and subframes
-
Strengthening structures during assembly of bodies and platforms
-
Equipment supports and fastenings
-
Protective covers and machine bodies
🔧 3. Production equipment
-
Designs for machines and presses
-
Mounting and support frames
-
Posts and fences
-
Supports and bearing elements for units
🏢 4. Furniture and interior
Unequal angles are used in:
-
Production metal furniture
-
Manufacturing shelves, racks and display cases
-
Assembly office partitions
-
Frames for decorative panels
👉 Stainless steel corners are especially popular - they combine strength and decorativeness.
🛠️ 5. Private construction and country house structures
-
Construction greenhouses, canopies, gazebos
-
Manufacturing gates, wickets, fences
-
Gain wooden structures
-
Frames under hammocks, swings, ladders
⚙️ 6. Electrical engineering and ventilation
-
Frames for distribution boards
-
Supports and holders for cable routes
-
Fastenings for air ducts and channels
📊 Advantages of unequal angles over equal angles
| Parameter | Unequal angle | Equal angle |
|---|---|---|
| Form | Shelves of different widths | Shelves of the same width |
| Flexibility in installation | Tall | Average |
| Weight | Lower with comparable strength | Usually higher |
| Purpose | For specific nodes | Universal application |
| Use in design | Often | Less often |
🔩 Popular materials
| Material | Advantages | Where is it used? |
|---|---|---|
| Steel St3 (black) | Affordability, high strength | General building structures |
| Stainless steel | Corrosion resistance, aesthetics | Food industry, furniture, decor |
| Galvanized steel | Moisture protection, average price | Street, wet areas |
| Aluminum | Lightweight, corrosion resistant | Aviation, interior, exterior decoration |
🧮 Standard sizes of unequal angles
The most commonly used sizes are:
-
from 25×16×3 mm to 160×100×10 mm
-
length - standard 6 or 12 meters
-
according to GOST 8510–86 or manufacturer’s specifications
Company Art-Metal offers manufacturing custom-made non-standard unequal angles, including non-standard thicknesses, lengths, shelf angles and perforation options.
