Specific gravity of light steel keel

Light steel keel is a kind of skeleton material used in ceiling engineering, and its specific gravity varies in different applications. In the wall keel, ceiling keel, partition wall keel, outer wall keel, upper ceiling keel and non-upper ceiling keel, the specifications and cross-sectional dimensions of light steel keel are also different. According to relevant information, the proportion of light steel keel is between 50 and 150 types, and the specific value depends on the type and specification of the keel. The advantages of light steel keels include dry work, low energy consumption, flexible space division, easy removal, good decorative effect and stable performance

Precautions for light steel keel

Light steel keel in the installation process need to pay attention to the following points: first of all, the top and bottom should be used along the top of the keel and along the ground keel, vertical should have vertical keel, in the door frame should have reinforced keel, horizontal should have horizontal support keel. Secondly, along the top keel and the ground keel should be fixed according to the position of the elastic line. The fixing method can be used for shooting nails, expansion bolts, etc., and the nail distance is not more than 600mm.

Process performance of metal materials

The process performance of metal materials refers to the difficulty of obtaining welded joints under certain welding process conditions, including the combination of performance and performance. Bonding performance refers to the sensitivity of metal to form welding defects under certain welding process conditions, and the use performance refers to the applicability of metal welded joints to the use requirements under certain welding process conditions. Annealing is a common metal material heat treatment process, used to reduce the hardness of metal materials, improve plasticity, reduce residual stress, improve the homogenization of tissue and composition. In addition, the method to test the cold bending performance of metal materials is to bend the material sample to a certain angle around the bending center with a certain diameter or to contact both sides without bending center to judge whether the material is qualified.

Thickness of light steel keel

The thickness of the light steel keel varies by type and use. The thickness of the main bone is 1.2mm,38 main bone is 1.0mm,50 accessory bone is 0.5mm,60 accessory bone is 0.6mm, and the vertical and along the ground bone is 0.6mm. Light steel keel is divided into partition keel and ceiling keel. The standard spacing of the partition wall keel depends on the thickness of the surface gypsum board, and the thickness of the common mid-range gypsum board is about 0.95mm.

The difference between light steel keel and aluminum alloy keel

Light steel keel and aluminum alloy keel are commonly used in ceiling decoration materials, they have their own advantages and disadvantages. The light steel keel is mainly made of light steel, which has the advantages of changeable shape, stable performance, light and strong texture, and is suitable for families with small ceiling load-bearing. The aluminum alloy keel is made of aluminum alloy material, which has the advantages of changeable shape, stable performance, light and strong texture. It is stronger than the light steel keel and is suitable for the family with large ceiling load-bearing. The cost of aluminum alloy keel is high, so it is mostly used in the ceiling decoration of important occasions.

What is light steel keel

Light steel keel is a new type of building material, which is widely used in stations, hotels, shopping malls, playgrounds, terminals, office buildings, factories, interior decoration and other places. Light steel keel has the advantages of high strength and light weight, waterproof, dustproof, moisture-proof, constant temperature, sound insulation, etc. At the same time, the construction is simple and the construction period is short.

The role of light steel keel

Light steel keel is a new type of building material, mainly used for ceiling and ceiling decoration, with shockproof, dustproof, sound insulation, sound absorption and other functions. In addition, the light steel keel can also play a role in heat insulation, sound insulation, heat preservation, but also electrical, ventilation and air conditioning, communication and fire prevention, alarm pipeline equipment hidden layer. Compared with wood, the price of light steel keel is slightly higher, but it has a long service life and better waterproof and fireproof performance. Therefore, the choice of light steel keel or wood square should be based on personal needs and budget.

Application of Metal Materials in Aerospace

Metal materials are widely used in the aerospace field, including aluminum alloys, magnesium alloys, titanium alloys and nickel-molybdenum-tungsten alloys. These alloy materials have a long service life, excellent corrosion resistance and high temperature resistance, so they are widely used in aircraft and aerospace fields. Among them, aluminum alloy materials account for about 50%-70% of aircraft materials. In addition, metal materials also have an important position in the field of aerospace, such as metal matrix composites have broad application prospects in aerospace applications. The application of metal materials in the aerospace field is of great significance for improving the performance and safety of aircraft.

Application of metal materials

Metal materials account for 80% of regular weapons, of which steel materials account for the main position. However, with the modernization of weapons, the role of high-performance non-ferrous metal armor materials, structural special functional materials and composite materials is increasing. The use of aluminum alloy armored body materials has gone through four stages of development, from high-toughness weldable Al-Mg alloy armor to aluminum alloy gap laminated armor and aluminum alloy armor additional composite armor. Carbon fiber-copper composites and carbon fiber-lead composites are also widely used in various fields due to their respective characteristics. In addition, the innovative application of light metal materials and the development of lightweight industry, the application and development prospects of light alloy components in rail transit, and the surface modification and functionalization of biomedical materials have also attracted much attention.

What materials are included in metal materials

Metal materials include many types, some of the common metal materials include: 1. iron, steel, cast iron, etc., these materials are widely used in construction, machinery manufacturing and other fields; 2. aluminum, magnesium, titanium and other light metals, these materials are in Aviation, automobile manufacturing and other fields are widely used; 3. copper, nickel, zinc, etc., these materials are used in wire and cable, electronic equipment and other fields; 4. Silver, gold, platinum and other precious metals, these materials are mainly used in jewelry, medical equipment and other fields. In addition, there are many other types of metal materials, such as titanium alloy, aluminum alloy, stainless steel, etc.
