Weight of 1 meter of angle (equal and unequal), number of angles in 1 ton - table of all sections

An equal-flange corner is a shaped L-shaped metal product with equal sides (the same length of shelves). It is the most popular and leading type of profile rolled metal products used in various fields of industry and production.

The method of application depends on the type, hardness, width of the sides. The corner can be used during repairs to strengthen concrete structures, in construction as the basis of metal structures, as reinforcement in construction projects, or as a decorative element for decoration.

Corners come in different types, are distinguished by their versatility, low cost, ease of installation, and are manufactured in accordance with state quality standards.

Types of equal angle corner

Equal angles are classified according to the following criteria:

• mode of production;
• precision manufacturing;
• length.

Mode of production

There are two main types of equal angle angles, determined by the production method. These are the corners

• obtained by hot rolling;
• representing bent products.

Hot rolled products

Thus, an equal-flange angle GOST 8509-93 is made from rolled sections of suitable size using the hot rolling method. In this case, certain rolled products of square shape are used.

As a rule, low-alloy or structural steel is used. Its use complies with the current GOST 19281−89. It applies to rolled products made of high-strength steels. Such products can be used without additional heat treatment.

Bent corners

The corner GOST 19771-93 is a bent equal-flange corner. It is considered as a separate type of this product. It is produced using special machines by bending a strip of cold-rolled or hot-rolled sheets. The production uses carbon steel of ordinary quality, high-quality structural steel, and low-alloy steel.

Bent corners are characterized by lower strength and smaller tolerances for deviations specified in GOST, assortment, and other technical documentation. Although in reference books such products have the same names as rolling angles.

Manufacturing accuracy and length

Only equal angles from 4 to 12 meters can be classified by length. These are measured products. Moreover, each type of measured products has certain tolerances for the volume of unmeasured length (no more than 5% of the lot). The unmeasured length has a size of 3-12 meters and an error tolerance of up to 70 cm.

The manufacturing accuracy of the shelf width determines the production of corners of the following types:

• type A (maximum accuracy);
• type B (increased accuracy);
• type B (normal accuracy).

In addition, the shelves of the corners must be located strictly perpendicular to each other within the permissible values ​​​​according to GOST. The thickness of the shelves is also indicated in GOST and may have permissible deviations. The type of corner determines its main parameters and characteristics.

Product characteristics and features

The main characteristics of the corners include the weight of one linear meter and the cross-sectional area. A feature of this type of rolled product is considered to be high strength and rigidity of the product with a low weight of the profile. An equally important indicator is high manufacturing precision. This feature is taken into account to obtain an ideal even angle.

Weight of equal angles

The weight and other characteristics of the corners depend on indicators such as width, wall thickness, and manufacturing accuracy. The shelf width can be from 20 to 250 mm. Products are marked according to the shelf dimensions. The labeling indicates the name of the product and the size of the shelf. For example, “Equal angle 50”.

The weight of a linear meter of products is determined by quality characteristics, including the following indicators:

• type of metal;
• steel grade;
• corner size;
• product thickness.

For each product there are calculation tables indicating the mass and number of meters per ton of the batch. For example, it is calculated that the weight of a linear meter of a 50x50x5 mm corner is 3.74 kg. And the number of meters in a ton is 267.48 m.

All the necessary parameters of the corners of interest can be found in the table:

The table below shows all parameters in accordance with GOST 8509-93 . Also, for complete convenience, the number of meters in one ton of different sizes is given.

Steel equal angle: GOST

The documentation regulating the production of products reflects the physical properties and manufacturing methods, indicates product parameters and permissible deviations from the established norm. This takes into account the dependence of permissible deviations on wall dimensions and accuracy indicators.

GOST

GOST No. 8509-93 applies exclusively to hot-rolled equal-flange steel angles. And GOST No. 19771-93 regulates the production of the same, but bent corners. Both documents establish categories of product accuracy, its physical characteristics, and permissible deviations from standards.

GOSTs contain information about materials that can be used in manufacturing. These materials, in turn, must also comply with GOST requirements.

The documents contain tables and figures with section values, mass, and weight of one linear meter of products. The tables were compiled taking into account the profile area, thickness and width of the flanges, radius of curvature, reference value of metal density, and nominal dimensions. But such calculations usually do not take into account deviations that are inevitable in the production of rolled metal.

Assortment

The assortment of rolled metal products is a detailed classification of metal products grouped by size, physical characteristics, quality, and other characteristics. The range of equal-angle angles corresponds to GOST 8509-93. It contains tables with corner dimensions, cross-sectional areas, and reference indicators.

The assortment is used for accurate calculation of materials, which allows you to use building materials correctly, avoid overuse, and carry out effective interaction with suppliers.
