22.12.2019 18:15

Sheet metal profiled commonly used materials

 

1.Stainless steel plate

 

Definition: refers to steel that is resistant to corrosion by weakly corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt, also known as stainless acid-resistant steel.

 

Features: There are two kinds of light (mirror) and matte (brushed), good texture, slow oxidation, good flatness, smooth surface, high plasticity, toughness and mechanical strength, acid resistance, alkaline gas, solution and other media Corrosion. It is an alloy steel that is not easy to rust, but it is not absolutely rusty, but the cost is high, and the color is dark and single.

 

2. Cold rolled steel plate

 

Definition: Cold-rolled thin steel plate is an abbreviation for common carbon structural steel cold-rolled plate, commonly known as cold plate. A common carbon structural steel hot-rolled steel strip is further cold-rolled into a steel sheet with a thickness of less than 4 mm.

 

Characteristics: Rolling at room temperature does not produce iron oxide scale. Therefore, the cold plate has good surface quality and high dimensional accuracy. In addition to annealing treatment, its mechanical properties and process performance are better than those of hot-rolled thin steel plates. In the field of home appliance manufacturing, it has gradually been used to replace the hot-rolled steel sheet, which has high hardness and relatively difficult processing, but is not easy to deform and has high strength.

 

Advantages: strong plasticity, easy bending, cutting, welding, grinding, convenient processing, strong color adhesion, can be used for various signage of the shape, and the cost is lower, but the oxidation is fast, easy to rust (general baking paint treatment).

 

3. Hot rolled steel plate

 

Definition: Slabs (mainly continuous casting slabs) are used as raw materials. After heating, strips are made from rough rolling units and finishing rolling units, commonly known as hot plates.

 

Features: low hardness, easy processing, good ductility, relatively low strength, poor surface quality (with oxidation, low finish), but good plasticity, generally medium and thick plates, cold rolled plates: high strength, high hardness, surface finish High, generally thin plate, can be used as a stamping plate. The thickness and width accuracy are poor, and the edges often have defects such as wave shape, folded edge, and tower shape.

 

4. Galvanized sheet

 

Definition: In order to prevent the surface of the steel plate from being corroded and prolong its service life, the surface of the steel plate is coated with a layer of metal zinc. This zinc-coated thin steel plate is called galvanized steel. Galvanizing is a cost-effective and effective method of corrosion protection often used.

 

Features: anti-corrosion, long life.

 

5.Aluminum sheet

 

Definition: It refers to a rectangular material that is made of pure aluminum or aluminum alloy through pressure processing (shearing or sawing) with a rectangular cross section and uniform thickness.

 

Characteristics: It has good elongation and tensile strength, which can fully meet the general processing requirements (stamping, stretching) and high formability. It is industrial pure aluminum, with high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, heat treatment can not strengthen the machinability is not good; gas welding, hydrogen atom welding and contact welding, difficult to braze; easy to withstand This kind of pressure processing and extension, bending.

 

6.Aluminum-plastic board

 

Definition: A composite material processed by chemically treated coated aluminum plate as the surface layer material and polyethylene plastic as the core material on special aluminum-plastic plate production equipment.

 

Characteristics: It is composed of two materials (metal and non-metal) with completely different properties. It not only retains the main characteristics of the original composition materials (metal aluminum, non-metal polyethylene plastic), but also overcomes the shortcomings of the original group of materials, thereby obtaining It has many excellent material properties, such as luxury, colorful decoration, weather resistance, corrosion resistance, trauma resistance, fire resistance, moisture resistance, sound insulation, heat insulation, and shock resistance; light weight, easy processing and molding, easy handling and installation.

 

7.Acrylic board

 

Definition: Commonly known as plexiglass, chemical name is polymethyl methacrylate, which is a polymer compound polymerized by methacrylate. It is by far the best in synthetic transparent materials.

 

Features: high light transmittance, excellent weather resistance, especially for outdoor use, ranking first among other plastics, with both good surface hardness and gloss, great processing plasticity, can be made into various shapes and signage required .

 

8.Organic tablets

 

Definition: The chemical name is Polystyrene, which is a thermoplastic non-crystalline resin.

 

Features: colorless, odorless, odorless and shiny, light weight and cheap, low water absorption, good colorability, stable chemical properties, excellent electrical insulation, especially high frequency insulation, and some impact resistance , Weather resistance and aging resistance, good light transmission, resistance to general chemical corrosion, the price is cheaper than plexiglass (acrylic), can be machined, bent, screen printed, plastic.

 

9.PVC board

 

Definition: It is a vinyl polymer material, and its material is an amorphous material.

 

Features: Good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics, but low density, easy to deform, can not be baked.

 

10.Tempered glass

 

Definition: Tempered glass is actually a kind of pre-stressed glass. In order to increase the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass withstands external forces, it first cancels the surface stress, thereby improving the bearing capacity and enhancing the glass Resistance to wind pressure, cold and heat, impact, etc.

 

advantage:

 

1. The strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass, which improves the strength and also improves safety. Safe to use is toughened glass.

 

2. The increase of its bearing capacity improves the fragile properties. Even if the tempered glass is destroyed, small fragments without acute angles are displayed, which greatly reduces the harm to the human body. The tempered glass has a resistance to rapid cold and heat that is 2 to 3 compared with ordinary glass. It can generally withstand changes in temperature difference of more than 150LC, which has obvious effects on preventing thermal cracking. Disadvantages: 1 The tempered glass can no longer be cut and processed, and the glass can only be processed to the required shape before tempering. , And then tempered.

 

3. Although the strength of tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-rupture) when the temperature difference changes greatly, but ordinary glass does not have the possibility of self-explosion.

 

11.Endurance board

 

Endurance board (also known as PC board, polycarbonate, solid board, bullet-proof glass, kabulon board, solid board, polycarbonate board, aerial perspective board) is a high-performance engineering plastic polycarbonate or polycarbonate- --- Acids are processed,

 

characteristic:

 

Impact resistance, unbreakable: The strength is hundreds of times stronger than tempered glass and acrylic board, which is tough and safe, and has the best anti-theft and bulletproof effects.

 

Can be arched and bended: It has good workability, strong plasticity, and can be bent into arches and semi-circular shapes according to the actual needs of the construction site.

 

Light weight and easy to handle: It is only half the weight of glass, which saves time and effort in handling and installation, and is convenient and easy to manage. Weather resistance and excellent lighting: It can resist ultraviolet radiation for a long time, and the lighting effect is very good, which can save a lot of cost savings.

 

Common colors for endurance boards: transparent / lake blue / grass green / milk white / brown / sapphire

 

Conventional specifications: 1.22 / 1.56 / 1.82 / 2.1M (width) * Any length, thickness: 3.0-15.0mm

 

The main purpose

 

The endurance board is suitable for the singular decoration of the garden, the entertainment place and the gallery of the rest place

 

Applicable to the layout of telephone booths, advertising street signs, light box advertisements, and exhibitions;

 

Suitable for highway and urban elevated road noise barriers;

 

Suitable for modern ecological restaurant ceiling;

 

Applicable to bicycle sheds, sunshades and balconies on the balcony and roof rest pavilions in all units or communities;

 

12.Wood

 

Species: imported Porog (high cost), camphor, pine

 

Features: It is often used in some tourist scenic areas such as gardens and parks. It gives people a natural and friendly feel, but the cost is higher.

 

13.Stone

 

Type: Marble, Granite, etc.

 

Features: Not easy to damage, long service life, unique style and strong cultural flavor; but the material itself is too heavy, which is not conducive to processing, and it is not easy to modify the structure. Natural stone has a higher cost, and artificial stone is commonly used now.
