Steel sections form the backbone of modern construction and heavy engineering projects. Their ability to provide strength, flexibility, and design efficiency makes them a vital component for buildings, bridges, industrial facilities, and transport infrastructure. Each type of steel section has unique structural advantages suited to specific applications.     In this article, Cheongfuli (Xiamen) Co., Ltd. explores four of the most commonly used steel sections and how they contribute to achieving optimal structural performance in various industries.     1. Angle Sections (L-Shapes)     Angle sections, available as equal or unequal L-shapes, offer excellent resistance to shear and tension at corners and joint points. Their right-angled design makes them ideal for structural reinforcement, bracing systems, and connection members.     Common Uses:   - Structural bracing and framing   - Equipment and vehicle frames   - Corner strengthening and edge protection   - Decorative trims, brackets, and reinforcements       2. Beams and Columns (I-Beams & H-Beams)     I-Beams and H-Beams are among the most widely used structural shapes due to their outstanding ability to handle heavy loads. Their wide flanges provide resistance against bending and shear, helping support long spans and high-stress structures.     Common Uses:   - Building frameworks and support columns   - Bridges and large-span infrastructure   - Industrial platforms and heavy machinery bases       3. Channel Sections (C or U Shapes)   Channel sections combine efficiency and strength within a compact design. Their top and bottom flanges connected by a vertical web deliver rigidity while keeping weight low, making them a cost-effective choice for medium-duty structural tasks.     Common Uses:   - Framing for walls, floors, and ceilings   - Supporting rails and mezzanine floors   - Vehicle chassis and light construction projects        4. Hollow Structural Sections (HSS)   Hollow Structural Sections, available in square, rectangular, and circular profiles, offer excellent strength-to-weight performance. Their enclosed shape enhances torsional resistance and visual appeal, making them a favorite for modern architectural designs.     Common Uses:   - Load-bearing columns and tubular frames   - Industrial machinery supports   - Architectural and exposed structural designs   - Fencing, railings, and modular construction systems     Why Choose Cheongfuli (Xiamen) Co., Ltd.

  What Is Heavy Steel Plate?     Heavy steel plate refers to any steel plate that is 6mm thick or more. These plates come in a wide variety of grades and are widely used across construction, mining, energy, and automotive industries. Heavy steel plates are most commonly applied in structural and building projects, where strength and stability are essential.   Common Grades of Heavy Steel Plate     Cheongfuli offers a full range of heavy plate grades, including: Structural steel: SS400, S235JR, S355JR, Q235 Wear-resistant steel: NM400, NM450, NM500 Weathering steel: A588 GrA/B, A709HPS50W/70W Pressure vessel steel: A516 Gr70, A537 Cl1/Cl2 Shipbuilding steel: ABS-A, AH32, AH36, DH36, EH36, E40 Offshore steel: API 2W, API 2H   Each grade is alloyed to enhance strength, hardness, and durability, making these plates ideal for heavy-duty structural and industrial use.     Material Testing of Heavy Plate     As plate thickness increases, the risk of internal laminations—tiny defects formed during the rolling process—also rises. These flaws can reduce a plate’s structural integrity if left undetected.   To ensure quality, buyers often request Ultrasonic Testing (UT). This advanced inspection uses high-frequency sound waves to detect hidden layers, folds, or trapped gases, guaranteeing that your heavy steel plate is structurally sound and safe for demanding applications.     Sourcing Heavy Steel Plate with Cheongfuli     When sourcing heavy plate, it’s important to choose a reliable supplier with: A wide inventory of diverse steel grades, including rare specifications Strong global logistics and technical support   With over 9 domestic and 26 overseas offices and a professional sourcing team, Cheongfuli (Xiamen) Co., Ltd. ensures timely delivery and consistent quality for every heavy plate order.   Contact Us Whether for construction, shipbuilding, or pressure vessel projects, Cheongfuli can provide the right heavy steel plate to match your specifications.   Email: cfloffice@chinacnd.com Website: www.cflsteel.com Tel : 0592-2592583WhatsApp : +8617319312767

Selecting the right corrosion-resistant steel often comes down to choosing between tinplate and tin-coated steel sheets including thin tin coated sheet tin-coated cold rolled steel sheet and carbon steel tin coated sheet While both offer excellent rust protection they differ significantly in composition manufacturing processes and ideal applications.       What Is Tinplate Tinplate consists of a thin steel sheet coated with an extremely fine layer of tin typically measuring between 01 to 20 microns This material is generally produced from low-carbon steel and undergoes a precise electrolytic tinning process to achieve uniform coating distribution. The material features an exceptionally thin tin layer that provides outstanding corrosion resistance while remaining completely non-toxic and food-safe Its excellent formability and weldability make it particularly suitable for precision applications. Common applications include food and beverage packaging such as canned goods and aerosol containers as well as battery casings and decorative packaging solutions where a lightweight yet protective material is required.   What Is Tin-Coated Steel Tin-coated steel sheets including tin-coated cold rolled steel sheet and carbon steel tin coated sheet represent steel products with substantially thicker tin coatings compared to traditional tinplate These sheets are manufactured through either hot-dipping or electroplating processes applied to cold-rolled steel substrates. These materials feature a more substantial tin coating that enhances durability while maintaining the inherent strength of the cold-rolled steel base The thicker coating improves solderability and provides superior resistance to oxidation and environmental degradation.   Typical applications include automotive components such as fuel tanks and radiator parts electronic shielding solutions and industrial containers that demand both structural integrity and corrosion protection.   Key Differences: Tinplate vs. Tin-Coated Steel Feature Tinplate Tin-Coated Steel (Cold Rolled) Base Material Low-carbon steel Cold-rolled steel (stronger) Coating Thickness Very thin (0.1–2.0 µm) Thicker (2.0–12.0 µm) Manufacturing Process Electrolytic tinning Electroplating or hot-dip coating Strength Moderate Higher (due to cold-rolled base)
