Carbon Steel Q195 Q235 Q345D Factory Direct Sales China Standard H-Beam

H-beam is an economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio.

Features

H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure in all directions, and has been widely used.

Material Characteristics & Specifications

Each material grade is tailored to meet specific mechanical performance requirements, ensuring optimal suitability for diverse applications:

Q195 Carbon Steel: Boasting a minimum yield strength of 195MPa, this grade is characterized by excellent weldability, formability, and cost-efficiency. It is ideal for light-duty structural components, such as secondary framing, supports, and non-load-bearing structures, where moderate strength and 加工 flexibility are prioritized.

Q235 Carbon Steel: With a minimum yield strength of 235MPa, Q235 is a widely used general-purpose grade renowned for its balanced combination of strength, toughness, and workability. It exhibits reliable performance in welding, cutting, and bending processes, making it suitable for medium-load structures, including building frames, bridges, machinery bases, and transportation equipment.

Q345D Carbon Steel: A high-strength low-alloy (HSLA) grade with a minimum yield strength of 345MPa, Q345D is designed for demanding environments and heavy-duty applications. The "D" designation indicates its excellent low-temperature toughness (tested at -20℃), ensuring resistance to brittle fracture even in harsh climatic conditions. It is extensively utilized in large-span bridges, high-rise building columns, offshore structures, and industrial equipment requiring superior load-bearing capacity and durability.

Structural Advantages of H-Beam Design

H-beams, also known as I-beams, feature a distinctive "H" cross-section that delivers exceptional structural efficiency:

High Strength-to-Weight Ratio: The optimized cross-sectional design distributes weight evenly, providing superior bending resistance and load-bearing capacity while minimizing material consumption, resulting in lighter yet stronger structures.

Stability & Rigidity: The wide flanges and thick web enhance lateral stability and torsional rigidity, making H-beams ideal for supporting long spans and heavy loads without deformation.

Easy Installation & Fabrication: The uniform cross-section facilitates seamless welding, cutting, drilling, and assembly, reducing construction time and labor costs.

Quality Assurance & Factory Direct Benefits

Our H-beams are produced using high-quality carbon steel billets through advanced hot-rolling processes, adhering to strict quality control standards from raw material inspection to final product testing. Key quality assurances include:

Compliance with GB/T 706-2016 and international equivalent standards (e.g., ASTM, DIN) upon request.

Comprehensive testing (tensile test, impact test, bending test) to ensure mechanical properties meet specifications.

Surface treatment options (galvanized, painted, or black oxide) to enhance corrosion resistance for different operating environments.

As a factory-direct supplier, we eliminate intermediate distributors, offering competitive pricing, flexible order quantities (from small batches to bulk orders), and customizable dimensions (height, flange width, web thickness) to meet specific project requirements. We also provide timely delivery and professional technical support to assist clients in material selection and application optimization.
