Steel has been a fixture in the packaging industry

For more than 200 years, steel has been a fixture in the packaging industry. When people think of the many uses of steel, they usually think of industry. This includes oil, pipes and buildings.

However, the beauty of steel is its versatility. Therefore, with its durability and portability, it is no wonder that major manufacturers used it in packaging in the 19th century.steel tubing manufacturers

Steel has been a fixture in the packaging industry

Manufacturers and distributors of the 19th century were fascinated by the ability of steel packaging to be preserved indefinitely. Many products are canned during this time because they are transported over long distances – and shipped for long periods of time.

This happened mainly in Europe, but American industry did not take a long time to become popular. In 1877, Sherwin Williams applied for a patent for his “ready-to-use paint,” a revolutionary and ingenious invention at the time.

He turned to steel cans because they could be resealed and kept fresh in paint. This trend is as popular as wildfire. The first drink can follow the footsteps of steel packaging in 1935.

Zero competition:

Until today, no packaging materials can compete with steel. It protects against the effects of moisture, UV and gas weathering. In addition, it has become a staple food for pressurized aerosol products such as detergents, hair sprays, and the like.

More importantly, people are degraded by their appearance. The steel package is smooth, clean and dynamic. It can be decorated with paper labels or printed directly. Its shiny appearance is undoubtedly multifaceted.

Many modern manufacturers use embossing and embossing methods as well as matt lacquers to make steel packaging more upscale.

The understated appearance and unobtrusive nature of steel packaging make it an excellent medium for brands to evoke emotional and experimental brands.

Hopeful future:

Contemporary printing techniques can only make the stylization of steel packaging easier to obtain. However, the service life of steel in the packaging industry is not just based on aesthetics.

As individuals become more concerned about the environment, they seek more typical “green” packaging. However, many people still ignore the recyclability of steel.steel square bar

In Europe, steel packaging has been one of the highest recycling materials in the past 10 years. Americans also recycled 71% of steel cans. Letting more people know about the ability to recycle steel cans (and how to differentiate aluminum cans) will keep them alive in the packaging industry.

Steel packaging manufacturers must continue to boast of the reusability of their products. As a result, they will definitely stay active. With its unparalleled better shelf life, there is no doubt that steel packaging can satisfy every market – as well as every family in the United States.

The specification of steel angle for sale

Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other on both sides. There are equal angle steel and unequal angle steel. The sides of the equiangular steel are equal in width. The specifications are expressed in millimeters of side width × side width × side thickness.steel angle for sale For example, “∠30×30×3” means an equilateral angle steel with a side width of 30 mm and a side thickness of 3 mm. It can also be expressed by model number, the model number is the number of centimeters of the side width, such as ∠3#. Model does not indicate the size of different sides in the same model.

It is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal width and unequal thickness.

The specification of steel angle for sale

The specifications of the angle steel are expressed by the dimensions of the side length and the side thickness. At present, the specifications of domestic angle steel are 2-20, and the number of centimeters of the side length is the number. The same angle steel often has 2-7 different side thicknesses. The imported angle steel indicates the actual size and thickness of the two sides and indicates the relevant standards. Generally, a large angle steel having a side length of 12.5 cm or more is a medium angle steel between 12.5 cm and 5 cm, and a small angle steel having a side length of 5 cm or less.

The order of import and export angle steel is generally based on the specifications required in use, and the steel number is the corresponding carbon steel number. In addition to the specification number, angle steel has no specific composition and performance series.

The delivery length of angle steel is divided into two types: fixed length and double rule. The range of fixed length of domestic angle steel has four ranges of 3-9m, 4-12m, 4-19m and 6-19m depending on the specification number. The length of the Japanese angle steel is selected from 6 to 15 m.

The height of the section of the unequal angle steel is calculated as the width of the long side of the unequal angle steel. Refers to steel with an angled section and unequal lengths on both sides. It is one of the angles. Its side length is from 25mm x 16mm to 200mm x l25mm. It is rolled by a hot rolling mill. The general unequal angle steel specifications are: ∟50*32–∟200*125 thickness is 4-18mm.steel square bar

Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding industries, various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, Container racks, warehouses, etc.

Angle steel per meter weight = 0.00785 * (side width + side width – side thickness) * side thickness

For example, 50*5 angle steel: (50+50-5)*5*0.00785=3.73 (this algorithm can only roughly calculate the weight of the angle steel, the actual hardware manual shall prevail!)
