What kind of plate is used for steel structure? What are the materials of steel plates?

It is best to use tread plates for steel structures.

Do not use antiseptic wood, which is used outdoors and has a strong smell.

It is best to use patterned steel plates (which can be used directly), and wooden floors and bamboo floors can be laid on them.

If you make a bathroom upstairs, it is a patterned steel plate (preferably stainless steel, so you don't need to paint), mortar and then pave the floor tiles.

As long as it's good material! It doesn't matter if it's thin! It's still thick! In general, it is thin! Because the material is good!

This mainly depends on what kind of customer needs

The materials of the cold plate are: Q195A-Q235A, Q195AF-Q235AF, Q295A

Cold-rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold-rolled plate, also known as cold-rolled plate, commonly known as cold plate, and sometimes miswritten as cold-rolled plate. The cold plate is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no iron oxide scale is produced, therefore, the surface of the cold plate is high, the dimensional accuracy is high, coupled with the annealing treatment, its mechanical properties and process properties are better than the hot-rolled thin steel plate, in many fields, especially in the field of household appliance manufacturing, it has gradually replaced the hot-rolled thin steel plate.

It is mainly distinguished by the content of various elements inside.

For example, Q235, Q345 which is very common, Q235 is ordinary carbon steel.

Q345 is a low-alloy high-strength steel with better mechanical properties than the former, which is a little more expensive. The amount of MN is higher in the main interior.

304 is stainless steel with a high Cr Ni content.

It is a high-quality carbon structural steel.

CR12 is a tool steel and is also an alloy steel.

W18CR4V is high speed steel.

1Cr18Ni9Ti is a heat-resistant steel.

ZMN13 is a high manganese steel.

There are 4 commonly used materials for steel structure roofing panels, and the differences between them:

1. Color steel plate.

Single-layer color steel plate (color coated steel coil is used after being molded by the tile presser) (color steel plate, aluminum-magnesium-manganese plate, aluminum veneer, aluminum-plastic plate).

Roof panels --- veneer (color steel plate, aluminum-magnesium-manganese board, aluminum veneer, aluminum-plastic panel).

Single-layer color steel plate: The color steel plate is rolled into the profiled roof panel, and the thermal insulation performance of this roof panel is very poor.

Second, the roof composite panel.

On-site composite panel - laying glass insulation wool at the construction site, the roof panel can be processed on site according to the length requirements, the roof panel has good thermal insulation performance, the whole roof can be done without lap, and the transportation is convenient.

The common practice is: color steel bottom plate + glass wool on-site composite + color steel top plate generally has two methods: purlin exposed type and purlin hidden type.

3. Sandwich roof panel.

Sandwich roof panel - is made of two layers of waterproof color coated steel plate or other metal as a panel, the middle injection sandwich panel material is composite, commonly used sandwich materials are polystyrene, polyurethane and rock wool, this kind of roof panel insulation performance is good, but due to the factory processing, when the board length exceeds a certain requirement, transportation is more difficult.

Fourth, the steel skeleton light grid plate.

The steel skeleton light grid plate can solve the condensation and frosting phenomenon of traditional plates (such as color steel plates), and the construction difficulty of traditional plates (such as concrete plates) is greatly reduced, and the process of changing and reducing the waterproof layer can be integrated in the steel structure itself, and the functions of waterproofing, heat preservation, wind load, rain and snow load of the grid roof can be well realized.

The steel structure skeleton and the steel skeleton light plate (including floor slabs, wall panels, and roof panels) are made into integrated load-bearing plates, which can be made into multi-storey structure prefabricated buildings; The steel frame is equipped with external and internal wall panels to realize high-rise or super high-rise prefabricated buildings. Supporting detachable partition panels, refractory decorative panels, etc., so that all complex projects are processed and produced in the factory, and quickly assembled on site, improving the performance of the building and reducing the comprehensive cost.

1. What are the steel structure roof panels? 1. The steel structure sandwich panel, which is made of two layers of metal plate and a polymer cabinet core that is foamed and solidified in the middle of the plate, the finished product is easy to install, and light and efficient, which can avoid water vapor condensation, its strength has also reached the standard, and it looks very beautiful. 2. Color pressure plate, it is a kind of pressure plate made of color coated steel plate, which can be rolled and cooled into various shapes, usually used in industrial and civil buildings, its light weight, excellent strength, many colors, convenient construction, and also has the ability of earthquake resistance, fire prevention, waterproof, and has a long service life, no need to spend energy maintenance.

2. What are the advantages and disadvantages of steel structure? It has the advantage of excellent strength, and has the corresponding toughness, and the material is balanced, the safety performance is good, and the construction is also very fast, without spending a lot of energy. Its disadvantage is that the corrosion resistance is not good, although it has heat resistance, but the fire resistance, it is generally easy to crack at low temperatures.

Therefore, when choosing a building structure, we must take into account the environment and our own needs, and then combine building materials, and then we can formulate a good construction plan.

Third, the comparison between the steel structure and the concrete structure, the concrete structure is made of reinforced concrete, its load-bearing performance is excellent and very strong, and the fire performance is first-class, compared with the steel structure, it can save the effect of steel, so the cost is not high, it is also very common in the construction field, and the construction is very convenient.

The materials needed for the roof of light steel houses are; Plywood (or particleboard), linoleum, hanging shingles, sand-faced asphalt shingles. The roof structure frame is made of light steel materials, generally a large zigzag inclined roof or a herringbone roof, and then covered with multi-layer plywood (or particleboard), and then laid linoleum, hung tile strips and tiles, and sand asphalt shingles can also be directly used on linoleum. For beams and structural columns with concentrated loads, light steel materials are also used to connect into load-bearing beams and columns through appropriate combinations.

The walls and floors are hollow layers, and there are also reserved holes in the keel. As a result, all pipelines can easily pass through walls and floor levels.

The steel structure uses carbon structural steel (Q195, Q215, Q235, Q255, Q275, etc.), low-alloy high-strength structural steel, high-quality carbon structural steel and alloy structural steel and special-purpose steel.

The steel structure will be subjected to various forms of action (load, uneven settlement of foundation, temperature ridge balancing, etc.) in the process of use, so it is required that the steel should have good mechanical properties (strength, plasticity, toughness) and processing performance (hot and cold processing and welding performance) to ensure the safety and reliability of the structure.

The application of steel structure system to residential buildings can give full play to the good ductility of the steel structure, strong plastic change and shape ability, excellent seismic and wind resistance, and greatly improve the safety and reliability of the residence. Especially in the case of ** and typhoon disasters, the steel structure can avoid the collapse and damage of the building.

The five floors of my house were covered by Q235 steel at the beginning, but my dad disagreed and changed it to Q345 steel!

When preparing for construction, my third uncle, who is a steel trader, said that the use of Q490 can ensure that there is no problem for more than 100 years!

In the end, it was changed to Q490 steel during construction, but the cost was nearly 200,000 yuan higher!

1. If it is divided according to the processing method of the steel structure, there is one kind of hot rolling, and the other is cold-rolled steel plate, which is made of billet as raw material, and then through the process of rough and fine binding in the later stage, through setting the temperature and in accordance with certain standards, to meet the cooling requirements. And guess.

2. If you choose cold-rolled, it is also a finished product made of hot-rolled steel plate as the original age-old cover material, and then called to remove the oxide scale through pickling, which needs to be processed in a room temperature environment.

3. If it is divided according to its shape, some are striped with steel plates, and some are patterned or special-shaped steel and section steel on the surface. According to the treatment of the surface, some are galvanized or color-coated. If you choose galvanizing, it has better corrosion resistance and can prolong the service life.

There are two ways to galvanize this steel structure, one is hot-dip galvanizing, and the other is alloyed galvanizing.

4. If it is divided according to the thickness, some are thin, medium, thick, and extra-thick, and the thickness represented is different, such as the thin plate is less than 4 mm.

Steel plate is a flat steel made by pouring molten steel, cooling it and pressing it. It is flat, rectangular and can be rolled directly or sheared from wide steel strips.

The width of the sheet is 500 to 1500 mm; The width of the thickness is 600 to 3000 mm. Thin plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet. According to professional use, there are plates for oil drums, enamel plates, bulletproof plates, etc.; According to the surface coating layer, there are pinned jujube zinc sheet, tinned sheet, lead-plated sheet, rubber calendar, plastic composite steel plate, etc.

Structural steel refers to steel that meets a specific strength and formability grade. The formability of the rocks is expressed by the elongation after the tensile test has been interrupted. Structural steel is commonly used for bearings and other applications where the strength of the steel is an important design criterion.

The carbon content is approximate, and in some cases can be as high. It can be divided into ordinary carbon structural steel and high-quality carbon structural steel. The former has a lot of laughter and low quality.

It is used where the performance requirements are not high. Its carbon content is mostly below and its manganese content does not exceed. Its strength is low, but its plasticity, toughness and cold deformation properties are good.

Except in rare cases, heat treatment is generally not required for direct use. Most of them are made into bars, special-shaped steels, steel plates, etc. It has many uses and many uses.

It is mainly used in railways, bridges and various construction projects to manufacture various jujube metal components, mechanical parts and weldments that are generally not large in weight or need heat treatment. High-quality carbon structural steel is pure, less impurities, good mechanical properties, and can be used after heat treatment. According to the manganese content, it is divided into two groups: common manganese content (below and high manganese content.

The carbon content is below and is often used directly without heat treatment, or after carburizing and carbonitriding treatment.
