Q355 and S355 Grade Hot-Rolled High-Strength I-Beams Designed for Structural Framing Projects
Product Introduction
Standards & Grades
- Q235 Series: This falls under the category of ordinary carbon structural steel, with a tensile strength of ≥375 MPa and a yield strength of ≥235 MPa. It is extensively applied in building supports, factory structural beams and similar load-bearing components.
- Q355 Series: Classified as low-alloy high-strength steel, it delivers a tensile strength of ≥470 MPa and a yield strength of ≥355 MPa. It is ideally suited for load-bearing structures in bridges and high-rise buildings.
- S235 Series: Boasting a tensile strength ranging from 360 to 510 MPa and a yield strength of ≥235 MPa, this grade is commonly utilized in general building structures.
- S355 Series: With a tensile strength spanning 470 to 630 MPa and a yield strength of ≥355 MPa, it is well-adapted for heavy-duty applications such as load-bearing bridges and industrial working platforms.
- SS400: As a type of ordinary structural steel, it has a tensile strength of 400 to 510 MPa, making it suitable for manufacturing mechanical components and light-duty support brackets.
- SM490: A welded structural steel grade with a tensile strength of 490 to 610 MPa, it is a preferred choice for bridge construction and shipbuilding projects.
- ASTM A36: This carbon structural steel grade features a tensile strength of ≥400 MPa and a yield strength of ≥250 MPa. It finds widespread use in construction projects and mechanical frame structures.
Regular Dimensions
Applications of Steel I Beams
(1)Construction engineering: used for load-bearing structures such as beams and columns in factories and high-rise buildings.
(2)Bridge engineering: used as main beams or supporting members to bear vehicle and dynamic loads.
(3)Mechanical equipment: manufacturing crane rails, equipment brackets, etc. .
(4)Transportation: railway vehicle chassis, container frames, etc.
Packaging and Shipping
Packaging method:
Bundling and fixing: Use steel strapping, each bundle weight ≤ 5 tons to prevent deformation during transportation.
Rust-proof treatment: Apply anti-rust oil or plastic film on the surface, suitable for sea transportation and humid environment.
Transportation requirements:
Use flatbed trucks or containers for transportation to avoid stacking and overloading.
Storage should be kept dry and ventilated to prevent rust.
