Appearance

The appearance of corten steel is no different from ordinary steel,but after special process,it will show a completely different color from ordinary steel.
After special treatment of weather-resistant steel,a variety of colors of paint will appear on its surface,which is mainly manifested as black paint is a unique color on the surface of corten steel,and a layer of black will be produced after special treatment on surface of general steel.Silver paint is the spraying of a layer of silver plastic on the surface of general steel.

Price advantage

The price of ordinary steel is high because a lot of energy in the process of processing and transportation,and if it is not used for industrial construction,these energy will be wasted.But corten steel does not have this problem,the processing and transportation process of corten steel is carried out at room temperature.And the production process of corten steel is also very simple,no need for high temperature treatment,no special heat treatment equipment,the production cost is very low.In addition,corten steel is one of the steel materials,and when used in the construction industry,it can attract a large number of customers through preferential prices.Ordinary steel also has very large losses during processing and transportation,so corten steel is cheaper than ordinary steel.

Service life

After long-term exposure to the atmosphere,corten steel will produce a thin and dense oxide film on its surface,forming a dense layer of metal oxide on the surface.The main components of this film are iron,chromium,manganese,and a small amount of aluminum,nickel and copper,which protect the substrate from a variety of media in the atmosphere.Ordinary steel does not have this"protective film" function due to the different internal structure with corten steel.Therefore,the surface of steel is corroded by various media during use.

Environmental performance

The raw material of corten steel is steel plate,and after heat treatment,and then galvanizing and other anti-rust treatment,it meets the standard that can be used.Steel in the nature,can not be rust-free forever,only the life beyond the natural life can become qualified steel.If the raw material of corten steel is steel plate,it is possible to become corrosion-resistant steel.
Ordinary steel is easy to rust and corrode in the natural environment,does not meet the requirements of the construction industry, and requires constant material replacement.Corten steel does not have this problem.
If you compare corten steel with ordinary steel,it can be said that it has its own merits,although ordinary steel seems to have low price,good quality and long service life,but the cost of environmental pollution and ecological damage is very high,and corten steel has very advantages in the above aspects.
