Mild Steel I Beam with JIS G3101 SS400 ASTM A36 EN10025 for Structural Construction
1．Product Overview
Mild steel I beams are widely used structural steel sections designed for load-bearing frameworks and industrial construction systems. The I-shaped cross section provides high bending resistance and structural efficiency while reducing overall steel consumption compared with solid structural sections.
These beams are manufactured according to international standards including JIS G3101 SS400, ASTM A36, EN10025 S275JR, and GB Q235B/Q345B standards. They are suitable for industrial buildings, bridges, infrastructure projects, shipbuilding, machinery manufacturing, and steel structure engineering.
2．Technical Solution
The hot rolled and high frequency welded manufacturing processes provide stable section geometry, reliable structural strength, and consistent dimensional accuracy. The web and flange configuration is optimized to improve load distribution and bending resistance under structural loading conditions.
I beams can be supplied in different sizes, grades, and surface treatments according to engineering requirements and environmental conditions.

5．Applications
Mild steel I beams are widely used in:
6．Processing
Products can be supplied with customized cutting lengths and additional processing services including:
7．Advantages
8．How to Choose
SS400 and Q235B are commonly used for general structural construction. Q345B, ASTM A572, and S355JR are suitable for higher load-bearing requirements and heavy-duty structures.
Beam selection should consider span length, structural load, welding requirements, corrosion environment, and project design standards.
9．FAQ
Q1．What is the difference between I beam and H beam
H beams generally have wider flanges and stronger load-bearing capability, while I beams are commonly used for lighter structural applications.
Q2．Can customized lengths be supplied
Yes. Products can be supplied according to project-specific cutting lengths.
Q3．What surface treatments are available
Black finish, galvanized coating, painted surface, and blasted surface treatments are available.
Q4．What standards are supported
Products can be manufactured according to ASTM, EN, JIS, DIN, and GB structural steel standards.
Q5．What industries commonly use mild steel I beams
They are widely used in construction, infrastructure, shipbuilding, machinery manufacturing, petrochemical plants, and industrial steel structures.
