The core considerations for the mezzanine in steel structure projects are structural safety, compliance, and suitability for use, which need to be strictly controlled throughout the entire process from design to construction.

I. Design Stage: Consolidate the foundation of safety

Clearly define the load standards, which should include self-weight, live loads (such as personnel and equipment), and seismic loads, and avoid overloading design.

Select suitable steel materials, giving priority to common specifications such as Q235B and Q355B, to ensure that the material complies with national standards.

Optimize the design of node connections. Welding and bolt connections must meet the strength requirements to prevent nodes from becoming weak points under force.

Ii. Construction Stage: Control the quality of landing

The construction team must possess professional qualifications in steel structure, and the operators must be certified to work (such as welder certificates).

Materials entering the site should be inspected and accepted. The model, specification and quality guarantee certificate of the steel should be checked. If necessary, a re-inspection should be conducted.

Construction must be carried out strictly in accordance with the drawings, and the welding quality (free from defects such as slag inclusion and pores) and the tightening torque of bolts should be controlled.

Carry out proper fireproof and anti-corrosion treatment. After rust removal from the steel surface, apply anti-rust paint and fireproof coating to meet fire protection standards.

Iii. Compliance and Usage: Avoid Risks in the Later stage

Approval procedures should be completed in advance, and they must comply with relevant regulations such as architectural planning, fire protection, and structural safety to avoid illegal construction.

Control the height of the mezzanine to ensure that the upper and lower floors are comfortable to use, while meeting the requirements of ventilation and lighting.

It is strictly prohibited to modify the structure without authorization. During later use, do not cut or weld the steel structure, and do not increase the load beyond the design standard.
