Carbon and low alloy structural steel plates
Carbon structural steel plates and low-alloy structural steel plates are the two most widely used structural steel plates in the industrial sector. They are primarily used to manufacture mechanical components that bear or transmit loads, and engineering structures (such as bridges, buildings, and ships). Their core characteristics are their combined structural load-bearing capacity and ease of processing, with costs tailored to the needs of different scenarios.
Bridge steel plates are high-strength, high-toughness, weather-resistant special steel plates specially used to build the main structures of various bridges (main beams, bridge decks, piers, connecting plates, etc.), including highway, railway, cross-sea/cross-river bridges, etc. They belong to the core category of engineering structural steel and must meet the strict requirements of bridges in their long-term service life, such as bearing dynamic loads (vehicle and train collisions), complex environments (wind and rain, corrosion, temperature changes), and structural safety redundancy.
Wear-resistant steel plate is a specialty steel plate that utilizes specialized material composition, rolling processes, or surface treatments to significantly enhance both surface and overall wear resistance. Its core function is to extend equipment life and reduce maintenance costs under high-wear conditions, such as material impact, sliding friction, and particle erosion. Wear-resistant steel plate is not made from a single material but rather a diverse system of steel plates suitable for a variety of applications.
Die Steel Plate is a type of special steel plate used specifically for manufacturing various types of molds (such as stamping molds, injection molds, forging molds, etc.). Its core function is to meet the mold's key performance requirements such as hardness, wear resistance, toughness, and corrosion resistance during the forming process through specific composition design and heat treatment process, ensuring that the mold can stably produce high-precision, high-quality industrial parts or products in the long term.
Steel plates for building structures
Structural steel plates are specialized steel plates used in construction projects to bear loads, transmit forces, or resist external forces (such as earthquakes and wind loads). They are the core material of building structures such as frames, trusses, shear walls, and long-span roofs. Unlike ordinary steel plates, their performance indicators (such as strength, toughness, and weldability) are specifically designed to fully meet the mechanical requirements and construction characteristics of building structures, thereby ensuring the overall safety, stability, and durability of the building.
Boiler and pressure vessel steel plates
Boiler and pressure vessel steel plates are specialized medium-thick steel plates used to manufacture boiler pressure-bearing components (such as drums, furnace bladders, and water-cooled wall tubes) and pressure vessel components (such as shells, heads, and flanges). The core requirements for these steel plates are to maintain excellent mechanical properties, Weldable, and structural stability over long periods of time under specific temperature and pressure (even corrosive conditions) to ensure safe equipment operation and avoid major accidents such as explosions and leaks due to material failure.
Line Pipe Steel Plate is a specialty steel plate used specifically for the manufacture of long-distance pipelines (such as oil and gas pipelines and water pipelines) that transport fluids such as oil, gas, water, and mud. It is a key structural material in energy transportation and urban infrastructure construction. Its core requirements are high strength and toughness, along with excellent Weldable, corrosion resistance, and low-temperature resistance to withstand the complex working conditions encountered during pipeline laying (such as in the field, deep sea, and in low-temperature permafrost regions).
High-strength steel plates for construction machinery
High-strength steel plates for construction machinery are specifically developed to meet the structural requirements of excavators, loaders, cranes, bulldozers, and other construction machinery under high-intensity operations and complex working conditions (such as heavy loads, impact, wear, and corrosion). Their core characteristics lie in their excellent mechanical properties (strength and toughness) combined with good processability (welding and forming), significantly reducing equipment weight, increasing structural load-bearing capacity, and extending service life. They are a key material for achieving lightweight and high-performance performance in modern construction machinery.
Wind power steel plates are special steel plates designed specifically for key structural components of wind turbines. Their core function is to ensure the structural strength, toughness and durability of wind power equipment (especially onshore/offshore wind turbines) when they are subjected to complex loads (such as wind, gravity, vibration, fatigue, etc.) and harsh environments (such as low temperature, salt spray, ultraviolet rays, etc.) for a long time, so as to avoid wind turbine shutdown or safety accidents due to material failure.
Steel plate for shipbuilding and offshore engineering
The general strength structural steel specified in the China Classification Society specifications is divided into four quality grades: A, B, C, and D (i.e., CCSA, CCSB, CCSC, and CCSD); the high-strength structural steel specified in the China Classification Society specifications is divided into three strength levels and four quality grades.
