1. Stainless steel profile specifications

Stainless steel profile, refers to stainless steel bar through hot melting, extrusion, so as to get different cross-sectional shape of stainless steel materials. The production process of stainless steel profiles mainly includes three processes of melting and casting, extrusion and coloring. Among them, coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon coating, powder coating, wood grain transfer and other processes.
Stainless steel angle: specifications ∠10mmX10mm–∠150mmX150mm
Stainless steel flat bar, stainless steel square bar: specifications 10mmX10mm–750mmX750mm

2.Stainless steel profile classification

I. Classification by us
1. Architectural stainless steel profiles (divided into two kinds of doors and windows and curtain walls)
2. Radiator stainless steel profiles
3. General industrial stainless steel profiles: mainly used for industrial manufacturing, such as automated machinery and equipment, the skeleton of the cover and the companies according to their own mechanical equipment requirements custom molded, such as assembly line conveyor belt, lifting machine, dispensing machine, testing equipment, shelves, etc., the electronic machinery industry and clean room with the majority.
4, rail vehicle structure: mainly used for rail vehicle body manufacturing.

II, according to the alloy into classification

Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy grades of stainless steel profiles, of which 6 series is the most common. The difference between different grades is that the ratio of various metal components is different, except for commonly used aluminum profiles for doors and windows such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural stainless steel profiles, stainless steel profiles do not have a clear distinction between models, most production plants are processed in accordance with the actual drawings of customers.

3.Features of stainless steel building materials

2.Stainless steel profile


Product use of different welding performance requirements vary. A class of tableware on the welding performance is generally not required, even including some pot enterprises. But the vast majority of products need raw materials welding performance is good, like the second class tableware, insulation cups, steel pipes, water heaters, water dispensers, etc.

2、Corrosion resistance

The vast majority of stainless steel products require good corrosion resistance, like one or two types of tableware, kitchenware, water heaters, drinking fountains, etc. Some foreign businessmen on the product also do corrosion resistance test: NACL aqueous solution heated to boiling, pour off the solution after a period of time, wash and dry, weigh the loss, to determine the degree of corrosion (Note: the product polishing, because of the composition of the sand cloth or sandpaper containing Fe, will lead to test (when the surface rust spots)

3、Polishing performance

Stainless steel products in today’s society are generally polished in the production process, only a few products such as water heaters, water dispenser lining, etc. do not need polishing. Therefore, this requires the polishing performance of raw materials is very good. The main factors affecting the polishing performance are the following.
① raw material surface defects. Such as scratches, pockmarks, over acid washing, etc..
② raw material material problems. Hardness is too low, polishing is not easy to polish bright (BQ sex is not good), and hardness is too low, in deep drawing surface prone to orange peel phenomenon, thus affecting the BQ sex. High hardness of BQ sex is relatively good.
③ after deep drawing of the product, the surface of the area of great deformation will also be small black spots and RIDGING, thus affecting the BQ sex.

4、Heat resistance

Heat resistance performance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties.
The impact of carbon: carbon in austenitic stainless steel is strongly formed and stable. Fixed austenite and expand the austenite zone of the element. The ability of carbon to form austenite is about 30 times that of nickel, and carbon is an interstitial element that can significantly improve the strength of austenitic stainless steel by solid solution strengthening. Carbon can also improve the austenitic stainless steel in highly concentrated chloride (such as 42% MgCl2 boiling solution) in the performance of stress and corrosion resistance.

5、Corrosion resistance

When the amount of chromium in the steel atomic number of not less than 12.5%, can make a sudden change in the electrode potential of steel, from the negative potential to a positive electrode potential. Stop electrochemical corrosion

6.Stainless steel in architecture

A modernist architectural structure using the concept of exterior curtain wall. 1948, an office building in Schenectady, New York, with stainless steel decorative facade, so that the constant load on the facade is significantly reduced, thus allowing an additional floor without changing the original frame and foundation structure. 1950s in North America and other parts of the world there are many examples of the use of stainless steel curtain wall. For example, the Thyssenhaus in Düsseldorf, Germany, is one of the high-rise buildings in Europe using stainless steel. Trapezoidal curtain wall thickness of only 1.0mm No. 4 surface SS316 stainless steel decoration, is a building with a guide. Also, the high technology style Lloyd’s of London built in 1986 also used stainless steel curtain wall, so that the building’s artistic achievements continue to this day.
stainless steel is a very strong and durable material, with high strength and high ductility, completely impervious to water, he requires little or no maintenance, easy to form and weld. These unique properties are particularly suitable for roofs, whether flat, sloping, arched or curved. He can be colored with resin paint, as widely used in Japan for roofing, can also be hand-made or standard profiles made of uncoated metal roofing, many residential buildings, commercial buildings, municipal buildings and industrial buildings, stadiums and churches have been equipped with stainless steel roofing, many of which are decorated into a curved shape, increasing the artistic appearance of the building.
in the 1980s, in the United Kingdom first produced a lentil-shaped pattern of stainless steel flooring sheet as an alternative to corrosion-resistant carbon steel. Since then, due to the appearance, cleanliness, ease and frequency of cleaning (sometimes requiring chemical cleaning), the limitations of the sanitary environment and cost, stainless steel flooring has been used in many different industries, food processing plants, slaughterhouses, industrial and chemical plants, hospitals, motor rooms, and even commercial buildings, offices and railway stations are paved with stainless steel flooring, increasing the practical function of the building The flooring is made of stainless steel. Electro-polished stainless steel flooring has minimal potential to harbor bacteria and dust, and is particularly suitable for use in high-tech factories and food processing areas, where maintenance costs are low, making stainless steel the ideal material of choice.

7.stainless steel building case

Len Lye Museum / New Plymouth, New Zealand
With the completion of the Len Lye Museum, known as the most beautiful steel modern building in the world, the small city of New Plymouth, located at the southernmost tip of New Zealand’s South Island, has attracted a lot of attention from the global architectural community. The building’s facade is made of highly polished 316-gauge steel with an artistic curvilinear shape. The building resembles a shimmering beacon, which attracts the attention of all those interested in steel for the architecture, building and construction industry.
II. Chrysler Building / New York, USA
If we turn back the history to 1930, the then watchers were equally amazed by the dazzlingly beautiful roof panels of the Chrysler Building in New York, which was the first time ever to use stainless steel as decorative panels in a main building. What’s even more remarkable is that the roof of the Chrysler Building has only been serviced and cleaned three times in the past 87 years – in 1961, 1996 and 2001. And daily household cleaners were used. The inspection found the roof to be in excellent condition.
Three: Two Horses Sculpture (Scotland)
The Two Horses sculpture, 30 meters above the Firth and Clyde Canal in central Scotland, should be considered the most impressive piece of public art in the world. Scottish sculptor Andy Scott’s giant double horse head design was inspired by the old canal. The main contractor for the project, SH Structure, Inc. The head of the sculpture is made of 150 tons of 6 mm thick glossy 316L (S31603) stainless steel plate supplied and cut by Otokunp. A special lighting treatment is the finishing touch to the sculpture, providing a dramatic twin horse sculpture at night. The double horse sculpture was originally designed along an artistic perspective, but later in the collaboration, through a combination of traditional manufacturing techniques and excellent structural engineering, it successfully transformed into an outstanding work of public art.
