Krympress reports:
Sheet rental is one of the most popular types of metal rolling, actively used in construction, engineering, energy, aviation and many other industries. It is a metal sheets of various thicknesses and sizes obtained by hot or cold rolling. Despite a simple form, sheet rental has a wide variety of characteristics, so that here This fact is indisputable: the material finds application in almost all areas of production.
What is sheet rental
Sheet rolling is called metal products made in the form of flat sheets of certain thickness and width. It is produced mainly in metallurgical plants by deformation of a metal blank between rotating rolls. Depending on the temperature of the rolling, they distinguish:
- hot -rolled sheet — produced at a temperature above the recrystallization point of the metal. It differs with lower accuracy, but high strength.
- Cold rolled sheet — obtained at a temperature below the recrystallization point. It has a more even surface and accurate geometric parameters.
The thickness of the sheet rental can vary from 2 mm up to 160 mm. Depending on this parameter, the sheets are divided into:
- thin -leaved rental — up to 4 mm;
- Tolstolystal rental — from 4 mm and above.
Types of sheet rental
Modern industry offers a variety of types of sheet rental, which differ in production, surface, size, shape and other characteristics. Main types:
By production technology:
- A hot -rolled sheet — has a scale and a rough surface, is used where high accuracy is not required.
- Cold rolled sheet — differs in a smooth surface, used for the production of parts with high accuracy.
On the surface:
- Smooth — universal type, widely used in construction and engineering.
- Crowned (lentils or rhombic) — has protrusions to increase clutch, is used on stairs, ramps, flooring.
- Perforated — contains holes of various forms, is used in architecture, ventilation, filtration.
By the degree of processing:
- Galled — covered with a layer of zinc for protection against corrosion.
- Posited — connected to another metal to improve anti -corrosion and other properties.
- Covered by polymer — has a color coating for decorative and protective purposes.
What materials leaf rental are made of
Sheet rental can be made from various metals and alloys, depending on the tasks that it should solve:
Carbon steel
The most popular material. Carbon steel is distinguished by a good combination of strength and cost. Used in construction, mechanical engineering, the production of pipes and structures.
Stainless steel
It has high corrosion resistance. It is used in the food, chemical, pharmaceutical industry, in the construction of facades and interiors.
Aluminum and its alloys
Light, resistant to corrosion, are easily processed. Used in aviation, automotive, construction, design.
Copper and copper alloys (brass, bronze)
They have excellent electrical conductivity and corrosion resistance. They are used in electric power, architecture, decor production.
Titanium
Very durable, light, resistant to aggressive environments. Used in aviation, shipbuilding, medicine and chemical industry.
Popular brands became for sheet rental
The choice of steel brand directly depends on the requirements for strength, plasticity, corrosion resistance and other characteristics. Some of the most common brands:
Carbon steel:
- ST3 is a universal brand, used in construction.
- 09G2C — low alloy steel with high strength, is used in welded structures.
- 10, 20, 35, 45 — brands of structural quality steel for cars.
Stainless steel:
- 08x18n10 (analogue AISI 304) — resistant to corrosion, universal use.
- 12x18N10T — contains titanium, which increases resistance to inter -qurystalline corrosion.
- 10x17n13M2T (analogue AISI 316TI) — resistant to acids and sea water.
Heat -resistant and acid -resistant:
- 15x5m, 20x23N18 — are used in chemical and energy industries.
Scope of sheet rental
Due to the variety of characteristics and shapes, leaf rental is used almost everywhere:
Construction:
- facade sheathing, roofing;
- manufacturing of metal structures;
- Reinforcement and strengthening of structures.
Mechanical engineering:
- parts of the bodies and cases;
- frames and panels;
- Traffic under stamping.
Aviation and transport:
- Light aluminum alloys for lining;
- Titanium sheets for power nodes.
Chemical and food industry:
- containers, tanks and stainless steel pipelines;
- Equipment in contact with aggressive substances.
Energy:
- heat exchangers, steam pipelines;
- casings of turbines and generators.
Architecture and design:
- facade panels;
- perforated decorative elements;
- Sculptures and art objects.
How to choose leaf rental for specific tasks
The choice of sheet rental depends on several key factors:
Appointment:
Determine where and in what conditions the material will be used: indoors, on the street, in contact with moisture, chemistry, at high temperatures, etc.
Material:
- For universal use, carbon steels (for example, ST3) are suitable;
- for moist or aggressive conditions — stainless steel or aluminum;
- for high loads — low alloy brands of the type 09G2C;
- For decorative purposes — copper, brass or painted sheet.
Type of processing:
- cold -rolled sheet is suitable for accurate processing and coloring;
- hot -rolled — for massive structures without strict requirements for the surface.
Thickness and size:
It is important to choose a sheet of the desired thickness: too thin may not withstand the load, and too thick will be more expensive and more difficult to process.
Additional properties:
- the presence of galvanizing or polymer coating will protect against corrosion;
- Riffie will increase safety when used as a floor.
According to experts, sheet rental is not just a “metal sheet”, but a whole range of materials on which the strength, durability and reliability of finished structures and products depend. The correct choice of the type, brand and shape of the sheet ensures the compliance of the final product with technical and operational requirements. When selecting, it is important to consider both working conditions and affordable types of processing and materials.
