Cold-formed equilateral angle steel GB 6723-86

A Cold bending equal side corner steel is a type of steel that can be used in many different applications such as structural, automotive and aerospace industries. Cold bending is a process of bending steel into undinating shaped sections by passing it through a set of matched dies. This process is also used to form more complex shapes such as channel, angle, H and Z sections.

The application of cold bending equal side corner steel is dependent on the material properties and grade of the steel. Cold bending is commonly used to manufacture parts that are too complex and delicate to form by other methods such as pressing or rolling, or those that require a higher degree of accuracy.

GB 6723-86 is a standard specification for cold bending equal-side corner steel. This standard specifies the requirements for cold bending equal sides corner steel including dimensions, chemical composition, and mechanical properties. It is designed to ensure a higher degree of accuracy and uniformity in the manufacture of the steel parts, and to ensure the safety and reliability of these parts.

The steel used for the cold bending process must be of the highest quality and must meet all the requirements specified in the standard. It must also comply with the mechanical properties specified in GB 6723-86. These properties include tensile strength, yield strength, elongation, hardness, ductility, and impact strength. The steel must also be free from any defects or contaminants, such as cracks, pinholes, laminations, and inclusions.

The steel must also be tested to ensure it meets the requirements of the standard, and to ensure it can withstand the heat exposure during the bending process. The steel must also be tested for other conditions such as corrosion resistance and the ability to retain its properties after the bending process.

The cold bending process is highly complex and requires skilled and experienced personnel. The personnel must be knowledgeable in the use of equipment, techniques and procedures for bending the steel in accordance with the standard. The correct techniques, equipment and procedures must be used to ensure a good finish and consistent results.

GB 6723-86 is a standard specification for cold bending equal side corner steel, and is an important guideline for anyone involved in the production or use of cold-bent parts. The standard ensures the safety and high-quality of the parts, and helps to guarantee the reliability of the parts. This standard provides for a high degree of accuracy in the fabrication process, and helps to ensure that the parts have a consistent quality and uniformity in their performance.

Cold bended equal-sided angle steel is the common material for steel structure architecture. It is special section steel with L-shape one side of them are 90° corner. It is made from high quality carbon structural steel and alloy structural steel. In normal situation, its surface should be oiled to protect it from rust.

Through cold-bending processing, it can be bent with different angles and edges. There are various length, height, shape and specifications. Different shape of steel makes it easier to combine and build varied structures of architecture.

Cold bended equal-sided angle steel also has many other advantages like strong compressive strength, good heat resistance, low cost. It can also be used in a variety of construction projects such as bridge, ship, lightweight steel structure, etc.

GB 6723-86 is the national standard for cold bended equal-sided angle steel. Steel shall comply the requirements in terms of product type, chemical composition and mechanical properties. The product should be inspected and tested during product processing and before delivery to guarantee the quality of steel.

In conclusion, cold bended equal-sided angle steel has become the common material for many building projects. Besides, it also has many other advantages. Adhering to the standard of GB 6723-86 is necessary to guarantee its quality.
