Angle steel

Angle steel is commonly known as angle iron, and its cross section is a strip of steel whose two sides are perpendicular to each other to form a right angle. Angle steel can be divided into equilateral angle steel and unequal angle steel. The length of two vertical sides is the same as that of equilateral angle steel, and the length of one vertical side is unequal angle steel. The specification is expressed in millimeters of side width × side width × side thickness. The main purpose of angle steel is: it is mainly used to make frame structures, such as Tower frame for high-voltage transmission, frame on both sides of steel frame bridge main beam, column and arm rod of tower crane on construction site, the column and beam of the workshop, etc., small places such as the shelf of flower pots on the roadside, the shelf of air conditioning solar energy hanging under the window, etc.

I. Marine angle steel

Main product description of marine angle steel: due to the harsh working environment of the ship, the performance of marine angle steel materials is required to have good toughness, high strength, good corrosion resistance, welding Performance and surface performance, etc. The chemical composition of the material is also different from that of ordinary angle iron. Its main purpose is: mainly used for Hull Int Comp, etc. 3 N7

II. Flat-bulb steel

Flat-bulb steel is a medium profile mainly used in the field of shipbuilding and bridge building, among which marine flat-bulb steel is an auxiliary medium profile for shipbuilding. The main product features are:

1. The appearance is round, no grain and no rib, and the surface of other steel bars is carved or ribbed. This results in a small bond between flat steel and concrete, while a large bond between other steel bars and concrete.

2. The flat steel produced by converter is mainly made of molten iron as raw material, with less harmful elements in molten iron, and the quality of the flat steel produced is guaranteed.

3. Continuous casting billet has a high sizing rate, which can ensure the sizing rate of flat steel and meet the needs of users.

III. L-shaped steel

L-shaped steel, also known as unequal-thickness angle steel, is a new type of profile produced to meet the needs of the construction of major ship. In addition to major ship, L-shaped steel can also be used for marine engineering structures and high-demand building engineering structures. Its main advantages are:

1. Under the condition that the height of steel is the same as the thickness of abdomen, the section coefficient and rigidity of L Steel are larger than that of flat-bulb steel

2. When the cross-section coefficient is the same, the thickness of L-shaped steel panel is slightly thinner than that of flat-bulb steel, which is conducive to improving the quality of the weld.

3. Under the condition of the same cross-section coefficient, increase the storage capacity of the ship and improve the economic benefits.
