Why choosing the wrong color will make Prepainted Galvanized Steel Coil less useful

The durability of the coating is the performance of the color steel coil during use, which is usually measured by the aesthetic life and the first overhaul life.
1. Beautiful life
The time interval from the completion of the manufacture of Prepainted Galvanized Steel Coil to the occurrence of a certain degree of discoloration and chalking of the surface coating, which affects the original aesthetic effect of the coating.

2. Coating thickness
Porous tissue coating. Microscopically, the coating is a porous structure, and water and corrosive media (chloride ions, etc.) in the air will invade through the weak part of the coating, causing corrosion under the film, and then the coating will foam and peel off.
coating color
From the technical point of view, the choice of pigments for light-colored paints is large, and inorganic paints with superior durability (such as titanium dioxide, etc.) can be selected, and the heat-reflecting ability of the paint is strong (the reflection coefficient is twice that of the dark paint). Summer paint The temperature itself is relatively low, which is beneficial to prolong the life of the coating. In addition, even if the coating is discolored or chalked, the contrast between the light-colored coating and the original color after the change is small, and the effect on the appearance is not large.

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.

Production process of welded steel pipe

The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling and transportation of oil and natural gas have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits

Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September

According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
