How to choose scaffolding suitable for a specific project?
Aug 13,2025
Choosing scaffolding suitable for a specific project requires a comprehensive consideration of the project type, construction requirements and safety regulations. The following are the key points:
1. Select the typebased on the project characteristics
The coupler-type steel pipe frame: It has strong versatility and is suitable for the construction of various building main structures and formwork support operations, but its assembly and dismantling efficiency is relatively low. The spacing of its vertical poles is usually 1.5 to 1.8 meters and it needs to be used in conjunction with swivel fasteners, right-angle fasteners, etc.
Bowl buckle type/disk buckle type frame: suitable for scenarios such as chimneys and tunnels that require quick assembly and disassembly. The socket design makes its stability superior to the traditional fastener type, and the components are less likely to be lost.
Gantry frame: widely used in civil engineering and large-scale operation platforms, it has a high degree of standardization and is suitable for working conditions that require frequent adjustments.
Attached lifting frame: specifically designed for high-rise buildings, it can climb along the floor, saving materials but requires professional installation.
Aluminum alloy frame: lightweight and easy to move, suitable for short-term, low-load operations such as interior decoration and equipment maintenance.
2. Core selection criteria
Load-bearing requirements: the load capacity of structural scaffolding should be ≤300kg/m² (such as concrete pouring), and that of decoration scaffolding should be ≤200kg/m². Any excess capacity requires special design.
Height and span: For structures exceeding 24 meters, reinforced frames should be adopted. For cantilevered structures, the anti-overturning coefficient needs to be calculated.
Site conditions: In narrow Spaces, single-row frames are recommended. For soft foundations, additional pads or channel steel foundations should be added.
3. Security compliance verification
The materials must comply with mandatory standards such as GB55023-2022. For instance, the wall thickness of the steel pipe should be ≥3.6mm (with an allowable deviation of ±10%), and the torque of the fasteners should reach 65N·m.
The special plan should include load verification, detailed node drawings and demolition sequence. Anti-fall nets and tie-in components should be set up for high-altitude operations.
When making an actual choice, it is recommended to prioritize the assessment of the construction period and economy - for short-term projects, quick-release frames can be leased, while for long-term projects, standardized components are advisable to be purchased. At the same time, local regulations should be taken into account. For instance, in some cities, bamboo and wood scaffolding have been banned, and the use of new systems such as buckle-type scaffolding is now mandatory.
