Iron and steel is an iron-carbon alloy that is smelted and processed based on the carbon content using pig iron as the raw material. Steel has a carbon content of less than 2% and has the advantages of high strength, toughness and plasticity, weldability, sawability, high impact resistance, and good machinability.

According to shape, steel products can be divided into four categories: profiles, plates, pipes, and metal products. The high strength of steel makes it often used as a structural member of buildings. Common types include round steel, flat steel, I-beam, channel steel, angle steel, and rebar.

The commonly used steels in architectural decoration engineering mainly include stainless steel and its products, color steel plates, color steel plates, color steel plates, color grain plates, microporous sound-absorbing plates, and composite relief art decorative plates. Plate, mirror stainless steel plate, titanium mirror panel, enamel decorative plate, and light steel keel.

1.1 Stainless steel and its products

The disadvantage of ordinary steel is that it is very easy to rust. In order to provide good corrosion resistance during use, chromium and other elements are added to the steel to make alloy steel, that is, stainless steel. The higher the chromium content in stainless steel, the better its corrosion resistance. The added elements also include nickel, manganese, titanium, silicon, and other elements, which can also affect the strength, plasticity, toughness, and corrosion resistance of stainless steel. The application range of stainless steel products includes roofs, curtain walls, doors, windows, interior and exterior wall finishes, handrails, skirting, and so on.

① Stainless steel wire drawing plate

Stainless steel wire drawing plates provide a silky texture to the surface of stainless steel through related processing techniques. The surface of stainless steel wire drawing plates is matt, smooth and smooth, and more wear-resistant than ordinary bright stainless steel. Stainless steel wire drawing board decoration is commonly used in high-end hotels, clubs, etc.

② Mirror stainless steel plate

The mirror stainless steel plate is a polished stainless steel plate, divided into 8K and 8S.

Mirror stainless steel plate is smooth, luxurious, durable, durable, never rusty, and easy to clean. Can be used for decoration of columns, windows, counters, and ceilings in hotels, shopping malls, office buildings, waiting rooms, etc.

③ Colored stainless steel plate

Colored stainless steel plates are various bright colors made by special processing on stainless steel plates, including blue, gray, purple, red, blue, green, gold, orange, and brown, which can change color effects according to different lighting angles.

Colored stainless steel plate has good corrosion resistance and good mechanical properties. The color laminated layer can withstand a high temperature of 200 ℃ and will not fade for a long time. It is mainly used for elevator car panels, car panels, interior wall panels, ceiling decorative panels, etc. in high-end buildings, and can also be used as signboards, nameplates, etc.

④ Stainless steel coated steel plate

Stainless steel coated steel plates are made by adding a layer of stainless steel, copper, nickel, titanium, and other metals to the surface of ordinary steel plates to composite them. This plate can replace expensive stainless steel.

The production process of stainless steel coated steel plate is simple, its cost is low, and its processing performance is superior to that of pure stainless steel plate. Mainly used for indoor and outdoor decorative components, it can completely replace stainless steel plates.

⑤ Stainless steel microporous sound-absorbing plate

Stainless steel microporous sound-absorbing plate is a pattern composed of micropores processed on stainless steel plate, which has sound absorption effect and certain decorative effect.

Stainless steel microporous sound-absorbing plate has good sound absorption effect and decorative effect. It can be used for indoor ceilings and walls, such as elevators, computer rooms, various control rooms, precision workshops, theatres, hotels, and broadcast studios.

⑥ Stainless steel checkered plate

Stainless steel grating refers to a special processing technology that makes the surface of stainless steel plate have a concave and convex feeling. Due to its excellent corrosion resistance and skid resistance, stainless steel checkerboard has been widely used and has begun to be widely used. The earliest stainless steel checkerboard patterns were horizontal and vertical stripes. Currently, various products have been derived, such as squares, diamonds, leather, ceramic tiles, stone tiles, ripples, and so on.

Stainless steel patterned plates are mainly used in professional fields such as anti-skid and anti-corrosion, including building curtain walls, railway transportation, machinery manufacturing, and other industries.

⑦ Titanium mirror panel

Titanium mirror panels are made by forming a titanium nitride film on the surface of stainless steel plates through special processing techniques. The thin film layer has golden yellow, bright gray, and color.

The titanium mirror panel will not be oxidized, will not change color, and is wear-resistant and has high hardness. It has brilliant gold and elegant decorative effects. Can be used for interior decoration of high-end buildings.

2.1 Color coated steel plate (color steel plate)

Color coated steel plate, also known as plastic clad steel plate, is made of hot rolled steel plate covered with 0.2-0.4mm semi rigid PVC film or other resin. The paint can be formulated in various colors and patterns, such as cloth, wood, marble, etc. Currently, the product has thousands of colors and hundreds of colors. There are two types of this board: single sided coating and double sided coating.

Color coated steel plate is wear-resistant, impact resistant, moisture resistant, good insulation performance, good processing performance, and does not damage the coating during bending processing.

Color coated steel plates can be used for the decoration of interior and exterior panels, floors, ceilings, curtains, and other equipment such as radiators and ventilation pipes, as well as for transportation, agricultural machinery, and daily necessities
