HEA, HEB, and HEM beams have a wide range of applications in the construction and structural engineering industries. Some common uses include:

1. HEA beam (lightweight H-beam): Suitable for low-load and lightweight applications.

The core advantages are light weight, high material utilization, and easy installation. Its mechanical properties meet foundation load-bearing requirements, eliminating the need to bear extreme loads. Its main applications are:

Civil buildings: secondary beams, partition wall keels, and balcony frames in multi-story residential buildings/apartments;

Small industrial facilities: auxiliary support structures for lightweight factories (such as equipment platform secondary beams and maintenance walkway frames), and warehouse rack columns/beams;

Non-load-bearing or low-load-bearing applications: ceiling keels in commercial spaces (shopping malls, exhibition halls), and temporary lightweight shed frames.

2. HEB Beam (Medium H-Beam): Suitable for general medium-load scenarios

The core advantages of HEB beams are balanced mechanical properties (moderate bending and shear resistance), strong versatility, and high cost-effectiveness. They lie between the lightweight design of HEA beams and the heavy-duty design of HEM beams. They are the most commonly used type in construction and infrastructure, with primary applications in:

Industrial and commercial buildings: Main beams/columns for medium-sized factories, load-bearing frames for multi-story office buildings, and main load-bearing beams for supermarkets and warehouses;

Small and medium-sized infrastructure: Main beams for rural road bridges, load-bearing structures for urban pedestrian overpasses, and supports for small water conservancy facilities (such as aqueducts);

Equipment and structures: Base frames for medium-sized machinery (such as machine tool supports), main frames for steel canopies, and load-bearing columns for parking lots.

3. HEM beam (Heavy Duty H-Beam): Suitable for high loads and extreme working conditions

The core advantages of HEM beams are thick webs/flanges, large cross-sectional moments of inertia, and extremely high load-bearing capacity. They can withstand large bending moments, high axial forces, and complex loads (such as impact and vibration). They are primarily used in:

Heavy industrial facilities: Main beams/columns in heavy machinery plants (such as shipyards and metallurgical plants), support frames for steelmaking blast furnaces, and foundations for heavy equipment (cranes and rolling mills);

Large infrastructure: Main beams for highway/railway bridges, bearings for cross-river bridges, and pier-column connection beams for urban elevated highways;

Special high-stress applications: The bottom load-bearing section of transmission towers, support ring beams for large storage tanks (crude oil tanks and chemical tanks), and supports for heavy-duty transport tracks in underground mines.
