Q:Are lead contained in galvanized steel plates and plain steel plates?
According to the content of alloy elements, divided intoLow alloy steels (alloy elements less than 5%),Medium alloy steel (total alloy element is 5%-10%)High alloy steel (amount of alloying elements is higher than 10%).
Q:Is the pattern steel plate hot-dip galvanized steel?
A steel plate with a raised (or dented) surface on a surface (patterned, section). Pattern steel plate, also known as checkered steel plate, is its surface with diamond or protruding steel plate. The pattern can be a single diamond, a lentil shape or a round bean shape, or two or more than two patterns can be properly combined to form a composite pattern board. Pattern mainly from anti-skid and decorative effect. The comprehensive effects of antiskid, bending resistance, metal saving and appearance of the combined pattern board are obviously better than that of the single pattern board. Checkered steel plates are widely used in shipbuilding, boilers, automobiles, tractors, railway cars and construction industries.
Q:Is PCM steel better than galvanized steel?
The decoration of household appliances barrel and microwave oven shell. In addition to ordinary color products, pearl color, metal color products have become popular trend of home appliance shell decoration, such as silver frequency conversion refrigerator, full frequency space King refrigerators and network appliances shell adopts Haier special steel company research and development of home appliances.
Q:What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water swelling seal, rubber sealing strip, sealing plate, the three theory can effectively prevent outside moisture through concrete construction joints with, from the analysis of the sealing principle, construction technology, the three is a big difference, the effect is different. Taking an underground three story structure in an engineering project as an example, the advantages and disadvantages of using the three structures in different parts are analyzed.
Q:What is Larson steel sheet pile?"
The advantages of Larson steel sheet piles1. high quality (high strength, light, good water resistance);2., simple construction, shorten the period of time, good durability, life of more than 50 years;3. construction cost is cheap, interchangeability is good, can be reused 58 times;4., the construction has remarkable environmental protection effect, greatly reduces the amount of soil sampling and the use of concrete, and effectively protects the land resources;5., the timeliness of disaster relief is stronger, such as flood control, landslides, subsidence, quicksand and so on;6. Deal with and solve a series of problems in the process of excavation;7, for the construction task, it can reduce the space requirements;8, the use of steel sheet pile provides the necessary safety, and timeliness;9, the use of steel piles can be free from weather conditions;10, the use of steel sheet pile material can simplify the complexity of inspection materials and system materials;
Q:What does "rolled steel" mean?.
The surface of the rolling material is not original, and the price of the calendering material is relatively low. The calender material is generally applied to the surface which is not very high or is the surface treatment field.
Q:What kind of material does ordinary steel plate refer to in steel market?
This is not difficult to understand. The chemical composition of ordinary steel is very simple. It is only made of carbon and iron. But the alloy steel plate is according to the different design request and the construction request to deploy its chemical composition, the different design request will affect the alloy steel plate in the choice alloy element choice.
Q:What are the properties of deep drawing properties in sheet steel?
Refers to the change of the thickness of steel plate and the change of plane (length and width direction) when the steel plate is pressed.
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
Q:What is steel concrete?
The steel reinforced concrete structure for steel reinforced concrete in Japan (two, u, iron and iron bars, a}) structure. In Europe and the United States known as the concrete steel structure (SteelEnc, ED, Concrete) structure, in the former Soviet Union is known as the reinforced concrete structure. According to different forms of steel distribution, SRC structures can be divided into two types: solid steel, steel reinforced concrete and seamless steel reinforced concrete. At present, the solid steel reinforced concrete members are often used in seismic structures, and the typical section forms of solid steel concrete columns, beams, shear walls and joints are commonly used.
