This document provides a comprehensive reference for industrial scaffolding components designed to support safe, efficient temporary works in construction, maintenance, and industrial environments. The catalog details standardized accessories that interface with tubular steel scaffolding systems, enabling engineers and procurement teams to specify compatible parts without guesswork.
The catalog serves as a technical selection guide for scaffolding auxiliaries such as base plates, couplers, toe boards, brackets, and safety nets. It excludes primary vertical and horizontal tubes, focusing instead on functional add-ons that enhance stability, load distribution, worker protection, and adaptability to uneven terrain or complex geometries. Each item is documented with dimensional tolerances, material grades, and connection methodologies to ensure interoperability with EN 74 and BS 1139 compliant systems.
All accessories are manufactured from structural carbon steel conforming to S235JR or equivalent, with hot-dip galvanization per ISO 1461 providing a minimum zinc coating of 55 µm. Alternative materials such as stainless steel (Grade 304/316) or aluminum alloys are available upon request for corrosive environments or weight-sensitive installations. Mechanical properties including yield strength (≥235 MPa) and elongation (≥25%) are maintained across batches to ensure ductility under overload scenarios.
| Accessory Type | Standard Dimension Range | Tolerance Class |
|---|---|---|
| Base Plate (for 48.3mm tube) | 150x150mm to 250x250mm | ±2mm |
| Right-Angle Coupler | Internal diameter 48.3mm | ±0.5mm |
| Toe Board | Height 150mm; Length 1.0m–3.0m | ±3mm |
| Screw Jack Extension | Adjustable range 300–600mm | ±1.5mm |
Each accessory is rated for specific load cases defined in TG20:13 and NASC Guidance Note 4. For example, a standard right-angle coupler must resist a characteristic slip load of 6.2 kN before deformation, with a design resistance of 4.1 kN applying a partial factor of 1.5. Base plates distribute point loads over a minimum bearing area of 0.0225 m² to prevent soil punch-through on compacted gravel (allowable bearing pressure ≥150 kN/m²). These values are derived from finite element analysis validated by physical testing per EN 12811-1.
While standard dimensions cover 90% of applications, modifications are possible for project-specific constraints. Custom options include altered base plate thicknesses (6mm–12mm), extended screw jack lengths up to 1000mm, or perforated toe boards for improved wind flow. Non-standard coupler angles (e.g., 45° or 60°) require engineering review to verify load paths and connection integrity. All variants retain full traceability via material batch numbers and production timestamps.
Every production lot undergoes dimensional verification using calibrated CMMs and mechanical testing on 5% sample size. Galvanization thickness is measured via magnetic induction per ISO 1460. Test reports, material certificates, and CE declarations of conformity are available upon request. The PDF catalog includes revision control metadata to ensure users reference the latest version, with updates issued when standards evolve or new geometries are introduced.
Selecting the correct accessory depends on site conditions: adjustable base plates are essential for sloped foundations; swivel couplers enable diagonal bracing in irregular grids; toe board height must exceed 150mm to prevent tool drop hazards per OSHA 1926.502(j)(2). In petrochemical facilities, stainless steel variants mitigate chloride-induced stress corrosion cracking. For suspended scaffolds, specialized stirrup adapters replace ground-based supports, requiring verification of anchor point capacity.
