Iron and steel industry has changed a lot during last 40 years. Trust is one of the most important parts of this industry because now a lot of Chinese and other countries are making and changing the results of the analysis which impacts the trust issues. Today inspections are changing throughout the world because of the technology advancements, and it gives us an absolute advantage for its effective nature and convenience. We can reach a breakthrough in this field if sufficient research regarding visual analysis inspections is done. 
Mass producing analysis
China has become largest consumer and producer in the whole world. China industry regarding iron and steel has had a big impact on the development of its economy and this rapid production and output of steel products has made a lot of defects, which are affecting all the enterprises and factories around the world and finally this affects their brand image too. The advancement level of steel industry is continuously respected as a key pointer for a country's financial quality and comprehensive national quality. Steel industry is one of the vital fundamental businesses within the national economy, and it is one of the supporting industries for a nation to realize industrialization. China's steel industry has long been a major consumer of coal and other fossil fuels with low efficiency, making it a major contributor of greenhouse gas emissions in China. Also, because of its coal-dominated energy structure and high consumption of limestone, severe environmental problems have risen around the iron and steel production plants. China's steel industry has become the third biggest CO2 emitter, only second to the power industry and construction materials sector. The carbon emissions from steel industry accounts for more than 10% of the total carbon emissions in China. According to the statistics of the Ministry of Environmental Protection of China, there were iron and steel companies in 17 of the 20 most polluted cities in China from January to May of 2013.

The recognition and usage of Iron and ferrous products goes back to 2000BC. Evidence is found of manmade ferrous metals all the around China and India. After all these years of advanced technology, modern steel makers are still using the same old methods i.e. carbothermic process. Blast furnace in many forms has been an inseparable part of this industry world-wide, making and modernizing it has been continuously active since the beginning. Modern steel making is extremely in favor of using energy and capital, at the same time as being a major source of environmental concerns, it is directly related to the high energy consumption. A highly competitive market due to the demand and size of the products has been shown around the world which is directly affecting quality, price, and delivery. High capital costs, raw materials shortages, environmental concerns, and customer demands has been identified as four industrial controllers in steel industry around the world. Although these controllers are applied to all the materials and industries around the world but concerns around Iron and Steel products are still among the main and important criteria discussed. 
Steel varieties
- Steel billets and ingots.
- Steel slabs.
- Metal bars and rebars.
- Hot and Cold rolled coils.
- Steel sheets.
- Hot briquetted Iron (HBI).
- Sponge Iron and Direct reduction Iron (DRI).
- Hematite Iron Ore.
- Iron Mill Scale.
- DRI fines and DRI sludges.
- Iron pellets fines and Iron Ore Pellet fines.
The list above is the products and byproducts of Iron produced and manufactured in IRAN.
Let's go to IRAN
Steel industry has been recognized as one of the mother industries serving many different models of products. consequently, understanding the market inside and outside of the country is very important. Supply and demand are among the main factors related to the subject, but fortunately regarding Steel and steel products, Iran has a good potential and has its own market globally. Simultaneously, Iran is competing with a lot of countries such as Saudi Arabia and Germany which have a better quality and stronger supply that tightens the market. Countries such as China, Japan, India, America, Russia, South Korea, German, Turkey, Brazil and Ukraine are top 10 steel producers in 2016, according to the World Steel Association. Comparing steel production in selected countries showed that Iran is the largest crude steel producer in April 2017. This shows a significant difference in the production scale in Iran compared to global norms. 
Raw steel production in Iran, during 2020 was about 29MT which has been increased 13.4 since last year. Iran is one of the effective countries on the production of raw material growth in the Middle East and has been experiencing a noticeable growth in producing Metal and Iron products. Hence, at the end of 2020 Iran experienced a booming growth in this line of production among all the other producers and countries around the world and stood on the 10th place. Reports show that Iran is growing even more and respectively is reaching the 7th place in the next few years. Managing steel industry needs prudent and far-sighted decisions and designing new capacities with advanced technologies with general approaches. One of the management tools in this approach is dynamic science system. This approach can duplicate different suppling chains, and with the help of this duplicator, we can identify the unclear outcomes of the decisions. Suppose we have a balance between supply, demand and price, then demand for housing will increase, then the demand for steel will increase, with increasing demand for steel, steel price also increases. All in all, Steel and steel manufacturing processes and countries producing the product are all having potentials and Iran specially, has a bright future in the producing and manufacturing steel and steel products and I hope we have a bright future.
