About Steel Props

Steel props are steel load-bearing components used in construction/foundation projects to bear vertical/horizontal loads and control structural deformation. They are reusable, made of Q235/Q345 steel, and mainly divided into two categories: Adjustable Independent Steel Props (for formwork) and Large-Scale Foundation Steel Props (steel pipe/H-beam).

1. Adjustable Independent Steel Props (Scaffolding/Formwork Internal Support)

  • Structure: Composed of outer tube + inner threaded tube + top plate/flat plate + base + handle nut, with adjustable height.
  • Common Specifications: Pipe diameter Φ48/Φ60/Φ63, length 2.2m - 4.0m.
  • Function: Vertical support for formwork systems, replacing traditional wooden squares. It features quick leveling and strong load-bearing capacity (single prop can bear several tons).
  • Types: Lightweight (for civil buildings), Heavy-duty (for bridges/large workshops), and Special Steel Props for Aluminum Formwork.
  • Surface Treatment: Painting, hot-dip galvanizing, and plastic spraying for corrosion resistance.

2. Foundation/Structural Steel Props

  • Section: Steel pipe supports (Φ609, Φ800, etc.), H-beam/combined section steel supports.
  • Arrangement: Opposite support, angle support, cross support, diagonal support.
  • Application: Deep foundation pit support, tunnel initial support, and lateral force resistance of high-rise buildings.
  • Technology: Prestress can be applied to control foundation pit deformation.

Key Part Details

  • Couplers: The most versatile connectors. Right-angle couplers (cross-connect standing poles and crossbars), rotary couplers (connect diagonal rods), butt couplers (extend steel pipes).
  • Disk-Lock Scaffold Parts: Standing poles with disks, crossbars/diagonal rods with lock head bolts. Features fast erection speed and high node stiffness.
  • Scaffold Planks: Steel planks are the mainstream choice, with high strength, durability, and suitability for frequent turnover.
  • Base/Top Plate: Adjustable base is used for leveling uneven ground; top plate supports formwork keel.

Selection & Quality Points

  • Material: Main steel: Q235/Q345; Couplers comply with GB 15831 standard. Non-standard, rusted, or deformed parts are strictly prohibited.
  • Compatibility: Pipe diameter and wall thickness must be uniform (e.g., Φ48.3mm system). Steel props must match the diameter of scaffolding to avoid node stress concentration.
  • Surface Treatment: For damp construction sites, hot-dip galvanized steel props and parts are preferred, with a service life far superior to ordinary painted products.
  • Inspection: Each batch must be accompanied by a certificate of conformity and material report. Key parts are sampled to test load-bearing capacity and torque.

Surface Treatment Options

  • Hot-Dip Galvanizing: Suitable for heavy-duty steel props (e.g., 7660/7663 models). Galvanized layer ≥0.4mm, excellent corrosion resistance, not easy to rust.
  • Electro-Galvanizing: Galvanized layer ≈0.1mm, poor corrosion resistance, easy to rust.
  • Pre-Galvanizing: Optional for specific project needs.
  • Paint Coating: Cost-effective, available in custom colors.

Special Customization

  • 4860 Model: Cup-type design available, suitable for Chinese, Middle Eastern, and African markets.
  • 4048/4856 Models: Only available in cup-type design.

Application Scenarios

  • Formwork Engineering: Mainly uses adjustable independent steel props, combined with cup-lock/disk-lock scaffolding for full-house support.
  • Exterior Wall/High-Altitude Operations: Mainly uses coupler-type/disk-lock scaffolding, emphasizing safety protection.
  • Deep Foundation Pits: Large-scale steel pipe/H-beam steel props (often prestressed) are used to form a foundation pit support system.
