Classification of metal corners and their application

Metal angles are one of the most popular types of rolled metal, used in construction, industry, mechanical engineering, and domestic structures. Their versatility and strength make them an indispensable element in the construction of frames, supports, frameworks, and other load-bearing structures.

Company ArtMetal (art-metal.com.ua) supplies metal corners of various types and qualities. In this article, we'll take a detailed look at classification of metal corners, their types, sizes and areas of application.

What is a metal corner?

The metal corner is steel profile with a right angle of 90° between the shelves. It happens equal-shelf And unequal-shelf, has different thicknesses and lengths, which allows it to be used in a wide variety of designs.

Main functions of the corner:

  1. Increasing the rigidity and strength of the structure.

  2. Providing resistance to bending, compression and tension loads.

  3. Connection of metal and wooden elements in frames and trusses.

Classification of metal corners

Corners are classified according to various characteristics: shelf shape, production method, purpose and wall thickness.

1. By the shape of the shelves

  • Equal angle: both shelves are the same width.

    • Application: building frames, supports, beams, trusses.

    • Advantages: symmetry, ease of installation, uniform load distribution.

  • Unequal angle: shelves of different widths.

    • Applications: structures requiring reinforcement in one direction, suspension systems, connections to slabs and walls.

    • Advantages: saving metal while maintaining strength, easy installation in tight spaces.

2. By production method

  • Hot rolled angle

    • Produced by hot rolling of steel.

    • It is used in construction and industry where high strength characteristics are required.

    • Advantages: high mechanical strength, durability, load resistance.

  • Bent corner

    • It is produced from sheet steel by cold bending.

    • Used for lightweight structures and decorative elements.

    • Advantages: low cost, easy installation, design flexibility.

3. By type of material

  • Low-alloy steel - used for standard building and industrial structures.

  • Alloy steel - increased strength and resistance to loads and wear.

  • Stainless steel — resistant to corrosion, used on objects with high humidity, chemical exposure or decorative elements.

4. By appointment

  • Structural corners — used for load-bearing elements, frames and frameworks.

  • Finishing corners — used for decorative purposes, for finishing and reinforcing the corners of slabs, walls, and furniture.

  • Special corners — have non-standard dimensions or features (perforation, stiffening ribs) for specific industrial tasks.

5. By size and thickness

  • The length of the corners is usually 6–12 meters.

  • Shelf width: 20–200 mm.

  • Steel thickness: 3–20 mm.

  • The dimensions are selected depending on the load and purpose of the structure.

Advantages of metal corners

  1. Strength and stability — the corner is capable of withstanding significant compressive and bending loads.

  2. Versatility — can be used in frame, staircase, truss and decorative structures.

  3. Easy to install — corners are easily connected by welding, bolts and fasteners.

  4. Durability - especially when using galvanized or stainless steel corners.

  5. Economy - optimal strength-to-weight ratio, material savings.

Applications of metal corners

1. Construction

  • Building and hangar frames;

  • Stair flights, ceilings, trusses;

  • Supporting and load-bearing structures;

  • Frames and racks for industrial facilities.

2. Industry

  • Metal structures and equipment frames;

  • Suspension systems, pipeline supports;

  • Supports for cranes and heavy equipment.

3. Decorative and household structures

  • Railings, fences, furniture frames;

  • Gazebos, canopies, frameless structures;

  • Strengthening the corners of slabs and walls in finishing works.

4. Mechanical engineering and transport

  • Vehicle frames;

  • Supports and connecting elements of industrial equipment;

  • Strengthening structures under dynamic loads.

Recommendations for choosing a corner

  1. Determine the load and purpose of the structure — For load-bearing elements, choose hot-rolled equal-leg angles; for lightweight and decorative elements, choose bent or unequal-leg angles.

  2. Choose the right material - stainless steel for wet environments, low-alloy or alloy for standard designs.

  3. Thickness and width of shelves — are selected depending on the expected load and span length.

  4. Length of the product — Consider ease of installation and transportation; the 6–12 meter standard is suitable for most applications.

  5. Check the quality of the coating - galvanizing or powder coating extends the service life of the corner in an aggressive environment.

Conclusion

Metal corners are a versatile and reliable structural element used in construction, industry, mechanical engineering, and domestic projects. Classification of corners by shape, production method and material allows you to choose the optimal option for a specific task, ensuring strength, durability and cost-effectiveness of the design.

Company ArtMetal offers a wide range of metal corners of various types, sizes, and steel grades, allowing you to find the optimal solution for any construction or industrial project.

The correct choice of corner, its thickness, and fastening method ensures the safety and durability of the entire structure, minimizes operating costs, and increases the economic efficiency of the project.
