Hot Rolled Steel Corner - Angle Bar

Steel euro corners: types and characteristics

Steel corners are a type of shaped steel, which is characterized by an L-shaped shape. The main function of steel corners is to join together and create additional strength and stiffness in welded steel structures and framing elements. Also, corners are actively used in construction and metallurgy to eliminate cracks and voids when connecting two parts, distributing loads in supporting elements, etc.
Structurally, steel corners are a bent L-shaped profile with two shelves located at right angles.

One of the main standards that regulates technical tolerances, materials and manufacturing methods, dimensions of steel corners is EN 10095:

• EN 10095-1 - regulates the dimensions of hot-rolled steel angles;
• EN 10095-2 - regulates the dimensional tolerances of steel corners.

The classification of the roll-formed profile takes place taking into account several parameters.

Depending on the section:

• equal angles are steel profiles in which the flanges (edges) are parallel to each other, multiples in width and have the same bearing capacity;
• unequal angles are steel profiles, in which the flanges (edges) are parallel to each other, but not multiple in width. I also call this type of rolled metal non-isosceles steel corners.

Depending on the production method:

• hot-rolled corners are products in the production of which a steel billet (bloom) is heated to the recrystallization temperature and deformed by pressure to an L-shape on rolling mills. Hot-rolled corners are characterized by a pointed ridge at the fold and improved performance;
• bent corners are products that are made by gradually bending a pre-cooled steel slab. Bent or cold-drawn corners are characterized by a rounded ridge at the fold;
• welded corners are products that are made by laser welding of individual sheet strips. The production of welded corners is not widespread, mainly they are made for a specific project.

For the production of steel corners, structural steel grades are used, which are characterized by high flexibility of machining, resistance to corrosion and oxidation, as well as high strength and hardness. Among the most popular brands are S235J0 / 1.0114, S235J2 / 1.0117, S235JR / 1.0038, S275J0 / 1.0143, S275J2 / 1.0145, S275JR / 1.0044, S355J0 / 1.0553, S355J2 / 1.0577, S355JR / 1.00545, S355 S450J0 / 1.0590.

The dimensions of the steel corners according to EN 10056 are as follows:

• equal angles: width - 15-300 mm; height - 15-300 mm; shelf thickness - 1-30 mm;
• unequal corners: width - 15-300 mm; height - 15-300 mm; shelf thickness - 1-35 mm.

Steel angle properties

Structural steels, which serve as raw materials for the production of shaped metal products, are distinguished by high physical and mechanical properties. So, they weld well and allow a high cutting speed, show a low level of cold brittleness, and are characterized by high resistance to the formation of near-weld cracks. Steel corners made from structural steels are more cost effective due to the cost of raw materials for production.

It is worth noting that structural steels are tolerated for a long time without loss of quality to direct UV rays, high humidity, temperature drops, which is important for corners that are operated outdoors in unfavorable working conditions.

In general, equal and unequal steel angles are:

• structural strength;
• the reliability of the welded seam;
• additional rigidity;
• resistance to wear and deformation;
• accuracy of geometric dimensions;
• long service life.
• Due to these characteristics, steel corners are actively used in:
• construction of civil and industrial facilities;
• erection of bridges, supports, frames, stairs, etc.;
• laying of heating networks;
• metallurgy, architecture;
• production of wagons and special equipment;
• heavy loaded and large-span ceilings;
• utilities, etc.

Steel corners of large dimensions, for example, for example, an equal angle corner 250x250, are especially in demand in the power industry. With their help, power lines are installed, and such a profile is called the corners of the power transmission line support.
