Big Air Shougang Launches Snow-making Mode
On November 15th, in preparation for the 2023 FIS Snowboard and Freeski Big Air World Cup, Big Air Shougang launched its “Snow-making Mode.” Nine ice crushers made a rumbling roar as they crushed ice cubes into icy foam, and the staff pushed snow blowers to scatter the snow piles stacked in front of the ice crushers and spread them flat. The floating ice debris in the air drifted into people’s collars, giving them a refreshing feeling.

In the construction and industrial sectors, high-quality steel is a key material for withstanding mechanical loads and environmental factors, with round pipes being popular for their excellent performance. Often manufactured from carbon steel, alloy steel or cast iron, these pipes are characterized by high strength and corrosion resistance, making them suitable for a wide range of scenarios.
Core characteristics of round pipes
The most distinctive feature of round pipes is their round cross-section, which is available in a wide range of sizes (diameters of 15-100 mm and lengths of up to 7,000 mm) to meet different engineering requirements. The wall thickness (up to more than 12 mm) directly affects its load-bearing capacity and needs to be selected according to the actual application environment (e.g. temperature, pressure, etc.).
Surface treatment processes are varied and include:
Mechanical polishing: abrasives of different grit sizes are used to eliminate surface defects, and the finish can be further optimized by polishing paste.
Chemical polishing: utilizing acidic solutions to form a smooth protective layer.
Electrochemical polishing: Enhancement of surface corrosion resistance by means of an electrolytic process.
Hot-dip galvanizing: Forms a zinc layer on the surface to enhance rust resistance.
Main Application Areas
Oil & Gas: Used to transport oil and gas resources to ensure the safety and stability of media transportation.
Construction engineering: as a frame structure or support member, widely used in industrial plants, civil buildings and temporary facilities (such as pavilions, garages, etc.).
Water supply and heating system: suitable for hot and cold water pipelines and sewage treatment facilities, taking into account the needs of indoor and outdoor installation.
Chemical industry: stainless steel round pipe can withstand acid, alkali and other corrosive media, commonly used in chemical transportation.
Mechanical manufacturing and transportation: used in aviation, automotive and heavy equipment manufacturing, to meet the demand for high-strength, lightweight.
Decorative and auxiliary uses: small round tube can be used for railings, furniture and other decorative structures, both functional and aesthetic.
Round tubes have become an indispensable key material in modern industry and construction due to their excellent mechanical properties, various surface treatment technologies and wide application adaptability.
Stainless steel bars, as fundamental industrial materials, are widely used in machinery manufacturing, construction, petrochemicals, medical devices, automotive components, and other fields.
China is the world's largest producer of stainless steel, accounting for 56% of global production (2023 CRU data), with significant export advantages:
✅ Price Competitiveness: Lower domestic production costs, 15%-25% cheaper than European and American manufacturers✅ Comprehensive Specifications: Main grades such as 304, 316, and 430, available in round bars, square bars, hexagonal bars, and other forms✅ Mature Supply Chain: Well-established industrial clusters in the Yangtze River Delta (Jiangsu, Zhejiang) and Pearl River Delta (Guangdong)✅ Policy Support: Export tax rebates (some stainless steel bar products enjoy a 13% rebate)
Generally speaking, the internal length of a standard 20-foot container is approximately 5.898 meters, while the internal length of a 40-foot container is approximately 12.032 meters. Therefore, the length of steel cannot exceed these values.For more information about containers, please click on the topic for more information on containers.
