Representative steel types
A3q steel: a carbon steel suitable for riveted bridge structures, with certain strength and toughness, which can meet the force requirements of riveted bridges and is widely used in early bridge construction.
16q steel: a carbon steel specially designed for welded bridge structures, with good welding performance and comprehensive mechanical properties, which can connect various components into an integral bridge structure through welding technology and has been widely used in modern bridge construction.
Material Composition: Alloy steel plates for bridge construction are typically composed of alloying elements such as chromium, molybdenum, and nickel, which enhance their strength, toughness, and corrosion resistance. These alloys are carefully selected to meet the specific requirements of bridge construction, including the need for high strength and durability.
High Strength and Toughness: These plates offer high tensile strength and impact toughness, making them suitable for withstanding the dynamic loads and stresses experienced by bridge structures. Their high strength-to-weight ratio allows for the construction of lighter yet robust bridge components.
Corrosion Resistance: Alloy steel plates for bridge construction are designed to resist corrosion, ensuring the longevity and structural integrity of bridge components exposed to environmental elements, such as moisture, salt, and atmospheric conditions.
Weldability and Formability: These plates are engineered to be weldable and formable, allowing for ease of fabrication and construction of complex bridge structures. This characteristic facilitates efficient assembly and construction processes in bridge engineering.
Compliance with Standards: Alloy steel plates for bridge construction are manufactured in compliance with industry standards and specifications, ensuring that they meet the required quality, performance, and safety criteria for bridge applications.
Impact Resistance: These plates are engineered to provide excellent impact resistance, which is essential for withstanding dynamic loads, vehicular traffic, and environmental factors that bridges are subjected to during their service life.
Note:
1.Free sampling, 100% after-sales quality assurance, Support any payment method;
2.All other specifications of round carbon steel pipes are available according to your requirement (OEM&ODM)! Factory price you will get from ROYAL GROUP.
Hot rolling is a mill process which involves rolling the steel at a high temperature
which is above the steel’s recrystallization temperature.
Standard Packing: The plate packs aresecured with steel strapping to prevent shifting in transit.
Surface treatment: Anti-rust oil, PVC film, colorcoated package etc for protecting steel surface.
Customized Packing: FFW can provide customized packing solutions for export.
Delivery Methods: Good for sea, rail, road transportation, LCL or FCL.
Delivery time: Normally 7-10days after the receipt of payment by advace, depends on the quantity and destination.
Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)
