Product Detail
Equal and Unequal Carbon steel Angle bar are frequently used structural steel products in construction and are more efficient than flat bar shades or flat bar sections in supporting where the depth is greater in the direction of bar isively. Both are carbon steel L shaped profiles but what distinguishes these profiles is the size of their legs.
An equal angle bar has two similar length legs which are perpendicular to each other. They are mainly utilized in structural, framework, support, bracing or general strengthening applications that need uniform load bearing capability.
An unequal angle bar has two sides (legs) of different length so it creates an asymmetric L-shape. They are suitable for variable load under travel, space saving or unique design of structures such as flexible supports.
Both these can be obtained in a variety of standard sizes and are easy to weld, cut, drill, and fabricate. As strong, durable, and versatile as they are,carbon steel angle bars can be applied in various construction, industrial and infrastructure projects.

ASTM Equal Angle Steel
Grade:A36、A709、A572
Size:20x20mm-250x250mm
Standard：ASTM A36/A6M-14
Features
Equal angle bars of mild steelEqual angle bar is a kind of angle bar of equal length on both legs and made of hot rolled carbon steel which is widely used in the industrial and construction areas because of its strength, flexibility and it can be easily fabricated.
With two equal legs whose interior corners form a true 90 degree angle, these products are perfect for structural frames, bracings, supports, and general reinforcement work.
These mild steel angles are made of mild carbon steel material, which is a good choice for strength, rigidity and it is used in many workload applications. They also offer excellent weldability and can be cut to size, drilled, machined and customised according to your project needs.
While performance of mild steel is dependable, surface treatment such as galvanizing or painting may be necessary to protect it from corrosion when used in a hostile environment.
Because of the strength and multi-purpose characteristics, mild steel equal angle bar can be found in many applications such as building structures, industrial plants, machinery and infrastructure projects.
Application
Broad range of use: Equal angle bars are used for a variety of applications such as:
Framing, bracing and supporting walls in residential and commercial building construction.
Basic Structure and Support: Utility and fabrication requirements are both addressed in the need for basic frame and support for machinery, equipment, and storage.
Decorative Building Elements: Support brackets, corner guards, window and door trim.
Mechaniability and weldability: It is also possible to machine equal angle bars. As a result, they are ideal for many custom fabrication applications.
Durability and stability: Equally angled bars have double-sided thickness and symmetrical shape, that allows equal angle bars to have durability to resist heavy loads that they bear and to gain stability in structure when used for making any kind of structure.
Surface finish and coatings: Equal angle bars are offered with several surface finishing options including a mill finish or protective treatments that improve the durability and resistance to rust or other forms of corrosion.
Packaging & Shipping
The angle steel bars should be packed properly in order to avoid any damage and deformation during transportation, storage and handling.
1.Binding: Angle steel bars are generally straped with steel or iron wire to keep bunded together closely without moving while shipping.
2.Protective Wrapping: Every bundle is usually wrapped with plastic film, waterproof paper, woven cloth to prevent from damp, dust and rust.
3.Wooden Support / Pallets: In some cases, angle bars can be placed on wooden pallets or packed in wooden boxes to guarantee stability and minimize the risk of damage in the course of loading and unloading.
4.Secure Fixing: Bars are also tightly packed so they don’t rattle, bend, or scratch all while on a long haul trip.
5.Labeling: With information of size, grade, length, quantity, handling etc., “the label” is clear to identify the products included in the bundle.
6.Export Standard Packing: For high density freight-wood packaging is strengthened to meet QC and seaworthy export requirements which make it possible to withstand the long transit time.
