Unlike lightweight cold-formed profiles, Shixinda's China Hot Rolled I Beam has a high density of base material, with uniform internal grains, and no internal defects such as layering, porosity, or bubbles. The overall rigidity and anti-deformation ability are suitable for long-term heavy-load and dynamic load conditions.
- Integrated hot-rolled dense base material, with extremely strong structural stability
- National standard precision tolerances, high adaptability for on-site assembly
- Dual selection of high and low material grades, covering all scenarios of adaptability
- Resistant to impact and fatigue, with a longer service life
- Regular surface appearance, excellent compatibility for further processing
- Extremely versatile, suitable for a wide range of engineering applications

Strictly follow the GB/T 706-2016 standard for hot-rolled steel sections. The steel is produced through a single-piece hot-rolling process without welding connections. The flange inclination, web thickness, and straightness tolerances meet the standards. It has excellent vibration and fatigue resistance, suitable for use in truck frames, factory main beams, and equipment bases.
Q235B: Suitable for general factory buildings, simple steel structures, and lifting tracks, with high cost-effectiveness;
Q355B Low Alloy High Strength: Suitable for heavy-duty factory buildings, bridges, and large mechanical supports. It is stable under low-temperature and high-load conditions; Each batch comes with an original material certificate and furnace batch number. It supports third-party inspection by SGS, meeting the requirements for import customs clearance in overseas projects.
Before storage, each batch is straightened and inspected for appearance. Bending, cracks, and non-standard materials with size deviations are removed to prevent the shipment of substandard products and reduce on-site construction losses for customers.
- Geometric dimension tolerance sampling inspection: Randomly sample each batch to test the cross-sectional height, flange width, web thickness, straightness, and curvature. All parameters are controlled within the allowable error range of the GB/T706-2016 national standard, eliminating defective products such as bias measurement, side bending, and twisting.
- Mechanical tensile and yield strength testing: Through a universal testing machine, test the yield strength, tensile strength, and elongation of the profiles. The mechanical properties of Q235B and Q355B materials meet the standards, and the load-bearing capacity matches the structural design parameters, meeting the engineering load-bearing design standards.
- Low-temperature impact toughness testing: Conduct low-temperature impact tests for materials used in harsh cold conditions. The profiles show no brittle fracture at low temperatures and have stable toughness, capable of adapting to harsh construction environments such as northern low temperatures and high altitudes.
- Internal non-destructive flaw detection: Our Hot Rolled I Beam uses ultrasonic flaw detection technology to check for internal layers, cracks, porosity, etc. in the profiles, ensuring the integrity and density of the base material and eliminating structural safety hazards caused by internal flaws.
- Heavy-load static compression test: Simulate the real heavy-load conditions of factory main beams and crane beams for static compression testing. The profiles are uniformly stressed, with slight deformation, and can quickly rebound after unloading, without irreversible deformation. The structural bearing safety factor is high.
- Welding compatibility testing: On-site sampling welding tests. The profiles have good welding fusion, no cracks, no pores, and the weld joint strength meets the standards. The welding nodes are stable, meeting the requirements for high-strength steel joint construction in the steel structure.
