The Benefits of Prepainted Galvanized Steel Sheet

Metal buildings account for almost half of the low-rise non-residential buildings, and a large number of these buildings use high quality prepainted color galvanized coil plates for roofs and wallboards. Painted steel sheet is a cost-effective and durable product.

In many applications, proper selection of paint systems (pretreatment, primer and finish) can provide galvanized steel roofs and walls with a service life of 20 years or longer. However, in order to achieve this long service life, China PPGI corrugated roofing sheet factory must also consider many other issues, including the nature of the use environment, the thickness and conditions of galvanized steel sheets, and the coating of coated coils. Process and panel design and rolling process. Construction site problems, such as storage and treatment of rolled sheets, architectural design, installation practice and on-site maintenance, also affect the service life of pre-painted metal building components.

Pre-coated galvanized steel sheets have been successfully used for decades under various climatic conditions on roofs and walls.

Cold Rolled Coil Application

The following describes the cold rolled steel coil factory supplier to introduce the scope of use of cold rolled rolls to facilitate customers to better understand our products.

The cold rolled coil products produced by the cold rolled steel coil factory supplier are made of various fine processes and have flat plate shape, bright appearance, high elongation rate, uniform width and width, no heavy skin and cracks, and the thickness tolerance is not more than 0.02mm.

Cold rolled coils are commonly used in the corrosion-resistant parts of the automotive industry. They are used in the commercial industry for the storage and transportation of packaging utensils and materials. They are used in the construction industry for the manufacture of anti-corrosion industries and roof grills, civil construction roof panels, etc. In the fishery, it is used as a cold processing tool for food storage and transportation, and meat products.

In addition, in the light industry of tools, pipe materials, steel, stampings, and fitness equipment, furniture, leisure goods, etc., CRC is also very useful, it can be said that the use is very common.

Performance Difference Between Geotextile and Geomembrane

Geotextiles and geomembranes are commonly used in geotechnical materials. They are commonly used waterproof materials. Because there are many similarities between the two, and the names are very similar. As a professional smooth pond liner hdpe geomembrane supplier, below, we will introduce geotextiles for everyone. And the performance of geomembranes.

Geotextiles, as the name suggests, are made of non-woven fabrics. They are mainly used to reinforce foundations. Geomembranes are made of high-density polyethylene and are mainly used for seepage prevention. The combination of the two is a composite geomembrane, which is divided into a film and a film. Two cloths and one membrane have stronger anti-seepage performance. The high quality non woven geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving. It is a member of the large family of geosynthetic materials. It is widely used in highway, railway, water conservancy, large-scale construction, power plant ash dam construction, non-ferrous metal tailings treatment, environmental protection engineering, soil and water conservation, etc.

The high quality textured hdpe geomembrane is a plastic film. Geotextile is a member of the large family of geotextiles and geosynthetics. It is widely used in highways, railways, water conservancy, large-scale construction, power plant ash dam construction, non-ferrous metal tailings treatment, environmental protection projects, Soil and water conservation, etc. Geomembrane uses plastic film as the anti-seepage substrate, and the geotextile material composited with an on-woven fabric, its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film.

The above is the performance of high quality non woven geotextiles and geomembranes that we introduced for you, so we hope that through our introduction, we can better help you to distinguish. At the same time, we have first-class scientific research and development personnel, first-class technology, professional production technicians, advanced The processing equipment, the implementation of high-quality large-scale, assembly line, intensive production, to ensure the high quality of equipment, low cost. If you need, welcome your call!

Galvanized Steel Sheet Manufacturer

Zinc plating is a commonly used process in the industry. Its main function was to protect it, but with the advancement of the times, today's galvanizing has an important function, that is, its decorative effect. Shandong HENGZE New Material Co., Ltd. is one of China color corrugated steel sheet manufacturers. It has been continuously innovating in the galvanizing production process, so it has a good honor and reputation today.

Choosing HENGZE, first of all, your galvanized steel sheet is sure to pass the product, and the anti-corrosion function of the galvanized sheet is stronger. We also pay special attention to the production and processing. If you buy it, it is not only the quality of the galvanized sheet. Well, and its service life can be better extended.

The Development of Galvanized Coil Process

Although the history of electroplating has been more than 100 years old, it has been widely used in industrial fields, such as high quality prepainted color galvanized coil, existing galvanized steel coils, etc., which have continued to this day since the 1920s.

In electroplating history, galvanizing was one of the first coatings to be studied. Research work on electro galvanizing began in 1807 to 1827, and in 1829 some people used it on nails. In 1852, the United Kingdom issued the first patent for galvanizing, and in 1855 proposed a patent for silver plating. However, until 1915, tempering galvanizing was only in the real stage before the industry used a zinc sulfate bath. In 1921, the silver galvanizing process invented by Blum made a major breakthrough. Since then, the galvanizing process of smelting has two practical values. The composition and content range of the solution is very similar to the current standard high concentration cyanide galvanizing process.

In the 1930s and 1940s, electroplating workers conducted extensive research on galvanizing. The focus of the study was to improve the glossy appearance of the coating. Furfural, heterocyclic compounds, and sulfides are used as brighteners. In the late 1930s, a bright galvanizing process was introduced to make the galvanization of the sails more perfect and widely used in the production of structural parts. The high quality prepainted color galvanized coil has a wide range of processes, high work efficiency, good dispersion, deep coating, fine crystal structure, beautiful appearance and good corrosion resistance. It has occupied a dominant position in the late 1950s and is still abroad. widely used. According to reports, in the United States in 1975, the amount of sodium sulfate used for galvanizing reached 3 million pounds.

Things always have two sides. Although smelting galvanizing has the above advantages, since sodium is a dangerous drug, with the development of industry, the scale of electroplating is expanding, and oxidized electroplating sewage and exhaust gas cause serious pollution to the human body. The environment has finally caught people's attention. In order to solve the pollution problem of Peihua electroplating, electroplating workers have conducted in-depth and extensive research on the silver-free electroplating process. The human and material resources invested are far more than any period in the past, and academic research and practical problems of solving production are closely combined. Many types of airless galvanizing processes have been proposed to facilitate the development of the entire plating process.

The history of cyanide-free galvanizing is only about 15 years old, and it has been used in industrial production since the early 1960s. According to authoritative sources, before 1964, only 3% of the world's structural parts were galvanized, and by 1974 it had increased to 20%. It can be seen that the development speed is very fast.
