H-beam connection method

Welding connection
Method description: Connect two steel h beams together by arc welding or gas welding.

Ways to increase stability: Welding connection has the advantages of high connection strength and compact structure, which can ensure the strength and rigidity of the H-beam connection, thereby increasing the stability of the overall structure.

In the process, reasonable weld design and process can be used to ensure quality and further improve the stability and reliability of the connection.

1. Bolted Connection (Highly Recommended)

Method: Connecting two H-beams or components using high-strength bolts. This is the most common method for modern steel construction due to its efficiency.

Why choose this: It allows for fast on-site assembly without the need for professional welders. It is easy to disassemble, maintain, or adjust.

How we help: We offer Pre-drilling Services. We can deliver H-beams with holes strictly positioned according to your drawings, saving you labor costs and installation time.

Method description: Connect two h section steels together by bolts.

Ways to increase stability: Bolted connection is easy to disassemble and replace, and can be adjusted and maintained when necessary, thereby maintaining the stability and safety of the structure.

Using bolts and reasonable preload can ensure the tightness and stability of the connection and prevent the connection from loosening or failure.

2. Welding Connection

Method: Directly connecting steel beams using arc welding or gas welding to form a rigid joint.

• Why choose this: It offers the highest connection strength and structural rigidity (moment connection). Ideal for earthquake-resistant structures where gas and water tightness are required.
• How we help: Welding requires high-quality steel with good weldability. We supply H-beams in grades like ASTM A36, A572, S355, and SS400, ensuring strong and defect-free welds.

3. End-Plate Connection (Replaces "Mortise and tenon")

Method: Welding a steel plate to the end of the H-beam, which is then bolted to another beam or column.

• Why choose this: It combines the benefits of welding and bolting. It ensures a precise fit and excellent load-bearing capacity for heavy structures.
• How we help: We provide Cut-to-size and Plate Welding services. You receive ready-to-assemble components rather than raw materials.

4. Channel Steel / Splice Connection

Method: Using Channel Steel or angle plates as connectors to join two H-beams together.

• Why choose this: Suitable for extending beam lengths or reinforcing specific joints. It adds rigidity to the connection point.
• How we help: As a comprehensive steel supplier, we provide a "One-Stop Package." You can order H-beams, Channel Steel, and Angles together in one shipment to save on freight.

5. Riveted Connection (Historical/Special Use)

Method: Connecting beams using hot rivets.

Note: While historically common, this has largely been replaced by high-strength bolting. However, it is still used in specific heavy-duty dynamic load environments (e.g., old railway bridges) due to its fatigue resistance.

Mortise and tenon connection
Method description: Two h-shaped steels are connected together through mortise and tenon joints.

Ways to increase stability: Mortise and tenon connection is a traditional connection method with the characteristics of simple structure and beautiful appearance.

Through mortise and tenon design and processing, the tightness and stability of the connection parts can be ensured, and the bearing capacity of the overall structure can be improved.

Channel steel connection

Method description: Two h-beam metals are connected together through channel steel.

Ways to increase stability: Channel steel connection is a special connection method suitable for some special construction requirements.

Using channel steel as a connector can increase the rigidity and strength of the connection parts and improve the stability of the overall structure.
