As a country with a developed steel industry providing more than 50% of global steel output, however, China is now massively exporting steel, causing concerns about global oversupply. The main reason comes from the weakening of the real estate market, which causes the country's domestic consumption to decline. Join MRS Steel to learn more through the article below!China's steel industry boosts exportsAccording to a report by the National Bureau of Statistics, in the first 2 months of 2024, China exported nearly 16 million tons of steel, an increase of 32.6% over the same period last year. This is also considered the highest steel export level of the Chinese steel industry from 2016 until now.According to Nikkei Asia, China's steel exports this year will equal or exceed last year's level, as China is on track to export about 90 million tons of steel and closer to 110 million tons in 2015, when it will witness an increase in anti-dumping measures around the world. This shows that the Chinese government is gradually stimulating the country's economic recovery.China just reported its highest steel export figures in eight yearsCurrently, China provides about 55% of the world's steel output. Therefore, even a small increase in exports can lead to downward pressure on prices in world markets. Therefore, the Chinese steel industry's promotion of exports has affected the steel industries of other countries, especially Southeast Asian countries, which are China's main export markets. In September 2023, the country's steel exports to Thailand increased by about 60% year-on-year, with exports to Malaysia increasing by about 80%. The amount of steel exported to Indonesia doubled and to Vietnam more than quadrupled.Pressure for Vietnam's steel industryA large amount of imported steel from China continuously floods the Vietnamese market, causing great pressure on the domestic steel industry. In just the first 2 months of 2024, the amount of steel imported from China reached 1.8 million tons, of which Vietnam's HRC alone imported from China reached 1.4 million tons, accounting for 74.2% of the total amount of HRC imported in the first 2 months of 2024.The reality of China's steel imports increasing sharply in the context of Vietnam enjoying an import and export tax of 0%. Trade defense measures have been lifted; other steel products, such as galvanized steel sheets, color steel sheets, steel pipes, prestressed steel,... are not subject to any trade defense measures. Facing pressure from imported steel, since 2023, the Vietnam Steel Association has made recommendations to the government to strictly control the import of steel products into the Vietnamese market.Chinese steel exports a lot, causing pressure on Vietnamese steelAs China increases steel exports, the country is turning to high-value-added products, putting pressure on domestic steel producers such as Hoa Phat, Hoa Sen, Ton Dong A,... Once again, Vietnam's steel industry faces a big challenge when it has to compete with cheap steel sources from China. This raises a warning bell for Vietnam's steel industry to have appropriate policies to ensure its development. development of domestic steel enterprises.Above is the information that MRS Steel sends to you about the problem of the world steel industry having excess supply because the leading country in steel production, China, is promoting exports. With China promoting exports, it not only affects Vietnam's steel industry but also the steel industry of other countries.

When choosing a gutter system for your home, gutters made of PPGI/PPGL are considered a durable and long-lasting option compared to traditional materials such as aluminum or plastic. In this article, let's explore the advantages and disadvantages of using PPGI/PPGL for gutters, and take a closer look at the installation process, maintenance, and cost with MRS Steel.What are gutters? Which materials are suitable for gutters?Gutters are a term describing the drainage system of a house, typically installed at elevated positions such as on the roof to collect rainwater and shape the flow in the desired direction. There are various suitable materials for making gutters, with aluminum and plastic being typical examples. Aluminum gutters are often lightweight and can withstand harsh weather conditions, while plastic gutters are lightweight, easy to install, and unaffected by corrosion or rust, providing a cost-effective solution.In addition to the traditional gutter materials mentioned above, manufacturers have also designed another durable material to cater to gutter applications. Gutters made of PPGI/PPGL are specifically crafted to operate efficiently when combined with steel roofs, especially when using the same PPGI/PPGL material. Furthermore, the installation process for gutters made from PPGI/PPGL often requires specific considerations to allow for expansion and contraction, given the nature of steel as a metal.Benefits of using PPGI/PPGL for guttersUtilizing PPGI/PPGL materials for gutters brings not only a range of benefits in terms of durability and long lifespan but also meets the aesthetic needs of a home. This material is designed with special protective layers to resist corrosion from sunlight, rain, wind, and harsh weather, providing a comprehensive and versatile solution for gutter systems.Harmonizing with metal roofing, enhancing aesthetic appeal for constructionWhen gutters and roofs are made from the same PPGI/PPGL material, it creates a cohesive design in terms of color, patterns, and quality. This harmonious combination not only produces a unified appearance but also delivers a unique and modern aesthetic impression, making the home stand out and appear exceptional in its surroundings.High-quality zinc-aluminum coating and paint layers play a crucial role in protecting PPGI/PPGL gutters from the impact of sunlight. This not only prevents color fading but also maintains the color of the gutters over time. The stable color retention contributes not only to enhancing the durability of the drainage system but also to the overall appearance of the home.Durable for a long lifespanThe clear difference between traditional gutters and PPGI/PPGL gutters lies primarily in their lifespan. Specifically, traditional gutters, often made from aluminum or plastic, typically last for 10-20 years, whereas PPGI/PPGL gutters have the potential to extend their lifespan to over 50 years, thanks to their outstanding durability and corrosion resistance.PPGI/PPGL materials are designed to withstand sunlight, rain, snow, and strong winds through the combination of multiple protective layers. In regions with particular climates, especially those with heavy snowfall or strong winds, the robust mechanical structure of PPGI/PPGL gutters helps them withstand the pressure from strong winds without deformation or damage. Additionally, their waterproofing capability ensures that the gutters are not affected by the impact of snow, maintaining stability during winter. Moreover, these protective layers can resist corrosion caused by prolonged exposure to rain, preventing rust and maintaining effective water drainage for the gutters.Minimizing annual maintenance costsWhen considering the initial cost, it is important to note that PPGI/PPGL materials are generally priced higher than some other materials used for gutters. The primary reason for this higher cost stems from the high-quality production process of PPGI/PPGL, which includes the application of multiple protective coatings such as zinc and aluminum. However, when examining the long-term benefits of PPGI/PPGL gutters, such as the ability to maintain form and function effectively over time without requiring significant maintenance costs, this cost is considered worthwhile.All types of gutters require regular maintenance to ensure they can operate efficiently, including cleaning to remove debris or checking for any signs of corrosion or rust. However, PPGI/PPGL gutters tend to incur lower maintenance costs as they are equipped with zinc-aluminum coatings and high-quality paint layers that help prevent oxidation from environmental factors. This has significantly contributed to minimizing repair or maintenance expenses for the product.Looking for a reliable supplier of PPGI/PPGL for gutter installationPPGI/PPGL is a type of steel that undergoes a complex production process with multiple coating stages, requiring detailed techniques to ensure even paint layers and enhance the adhesion of the coating. However, the current market offers numerous suppliers of PPGI/PPGL with varying prices and sizes, posing a challenge for buyers to choose a reputable source that guarantees quality, suitable dimensions, thickness, and colors.Collaborating with a company knowledgeable about specific steel products and possessing years of experience in the galvanized steel sector will provide buyers with more peace of mind regarding product quality.

Stainless steel is one of the most popular materials in construction and civil manufacturing fields. Because of its durability and higher aesthetic properties compared to most other materials, the stainless steel production process is also quite complicated.History of stainless steelStainless steel is closely associated with the name of a British steel industry expert - Harry Brearley. He invented a special type of steel that has strong resistance to corrosion and rust by adjusting the Carbon and Chromium content appropriately.During the production process, Harry Brearley researched and added 8% Ni and 18% Chromium, successfully creating the 304 stainless steel grade that is very popular today. Because of its outstanding strength, stainless steel is widely used in many industrial and civil sectors.Understanding the stainless steel production processThe preparation of raw materials is the first factor that determines the success of the stainless steel production process. The elements iron, chromium, carbon, manganese,... are processed to remove impurities, ready for the next steps.Melting and castingSteel and alloy metals are added to an electric arc furnace and melted at temperatures above 2800 degrees F for continuously 8 -12 hours so that the metal completely turns into liquid. During the melting process, experts must regularly check the temperature and chemical composition so that the finished products are as desired.After completely melting the metal, the liquid mixture is crystallized with argon and oxygen to remove impurities such as sulfur, excess carbon and slag.To increase product applicability, refined steel is cast into billets, plates, bars,... or different shapes to suit all applications.FormingMost cast steel is shaped by hot rolling into sheet form while the billet is heated and rolled through a large roller to form steel plates, strips or bars.In addition to hot rolling, billets can also be cold rolled to form custom-sized steel blocks. Cold rolling typically uses small diameter wheels to produce a smooth, shiny surface with the smallest tolerances.Heat treatmentStainless steel is heat treated by heating and cooling under controlled conditions to relieve internal stress and soften the stainless steel. However, this stage requires strict control of the annealing temperature to ensure the quality of the stainless steel interior.DescalingAfter annealing and rolling, stainless steel still has a layer of oxidized residue on the surface. The factory needs to clean off the residue to restore the shiny surface of stainless steel. Currently, nitric acid and hydrofluoric acid are the most popular descaling agents. In addition, the electrolytic method is also used to remove residue from the surface.Stainless Steel TemperingThe purpose of heat treatment of steel is to increase the hardness and durability of the material. After annealing, stainless steel tends to become softer. When tempering steel, factories often use water because of its low cost and quick cooling effect. First, experts heat the material to about 815 - 900 degrees Celsius, then transfer the alloy to a water bath to suddenly reduce the temperature, maximizing hardness and durability.Cutting and machiningAfter the above processing steps, stainless steel is almost complete and can be manufactured into various industrial applications. In this step, the factory can cut and process steel into different shapes and sizes by cutting, sawing or techniques such as plasma, high pressure water jet,...Surface finishingStainless steel is famous for its high aesthetics and outstanding corrosion resistance, ease of cleaning and high applicability. To achieve these properties, stainless steel needs to be surface finished by annealing, hot rolling, cold rolling, grinding, polishing, sandblasting,...Methods of controlling stainless steel quality after productionAfter production, stainless steel needs to undergo a number of quality tests before being distributed to the market.Mechanical testMechanical testing measures the physical capabilities of stainless steel such as load-bearing capacity, stress, tensile strength, Brinell, toughness,...Chemical testingChemical testing aims to check whether the chemical properties of stainless steel meet standards through spectroscopic analysis. Besides, factories also test and measure the corrosion resistance level of materials by spraying salt water.If you have any questions or need to import Vietnamese steel, please contact MRS Steel via Email: vanloc@mrssteel.com.vn or Hotline: +842836223358 for the most thoughtful support!
