Steel structure member

In steel structure engineering, the common material selection mainly involves structural steel, coating materials and connecting parts. The following are some common steel structure engineering material choices:

Structural steel: Structural steel is the main material of steel structure, common structural steel includes:

Carbon structural steel: such as Q235, Q345, etc., suitable for general building structures.

Alloy structural steel: such as Q420, Q460, etc., with high strength, suitable for large span, high level and other requirements of high strength structure.

Stainless steel: For some special environments, such as Marine environments, food processing plants, etc., stainless steel may be a more suitable choice because of its good corrosion resistance.

Coating materials: steel structure members need to be anti-corrosion treatment during use. Common coating materials include:

Anti-corrosion coatings: including primer, middle coat and top coat, can improve the corrosion resistance of steel structure.

Hot dip zinc coating: Hot dip zinc on steel surface to form zinc layer, improve corrosion resistance, suitable for outdoor or humid environment.

Galvanized coating: Zinc layer is formed on the surface of steel by electroplating or hot dipping zinc to improve corrosion resistance.

Connector: Connector is a key component of the steel structure to connect and transmit force. Common connectors include:

Bolt: Bolt connection is a common connection mode, which can be divided into high-strength bolts and ordinary bolts.

Welding materials: welding is one of the common connection methods, welding materials need to choose the appropriate wire, flux, etc.

Stud connection: Stud connection is suitable for structures with high requirements for connection rigidity.

Support materials: In building structures, supports are needed to support and transfer loads, and support materials include:

Rubber bearing: has good shock absorption and vibration absorption performance, suitable for earthquake areas.

Metal support: Usually made of carbon steel or stainless steel, it is used to support the structure and allow a certain displacement.

Fireproof coatings and materials: For some buildings requiring fireproof performance, it is necessary to choose fireproof coatings and fireproof insulation materials to improve the fireproof performance of steel structures.

In the selection of materials, it is necessary to make a reasonable choice according to the requirements of the specific project, environmental conditions, budget and regulatory requirements to ensure the performance, safety and economy of the steel structure. In addition, factors such as the availability of materials and production processes need to be considered. The experience and knowledge of professional structural engineers and designers in the selection of materials is key to ensure the success of the project.
