Buying Used Scaffold Decks: Which Material Suits Your Project?
The deck is your team's working platform. But the choice between timber, steel and aluminium is not just a question of price – it is a question of load class and weather exposure.
Buying scaffold decks – steel, aluminium or timber?
The scaffold deck is far more than just a walking surface; it is the safety-critical foundation for efficient work at height. When choosing the right deck, load-bearing capacity, weather resistance and dead weight must be weighed against each other. In this guide you will learn how to assess used decks professionally.
Steel decks: the indestructible workhorses
Steel decks are the first choice for heavy work and high load classes (usually load class 4 to 6). With a current stock of almost 100,000 units in various categories, we offer maximum flexibility here.
- Advantages: Extremely durable, fireproof and resistant to mechanical damage.
- What to check when buying used:
- Hook-on claws: These must not be bent or cracked, to guarantee a secure fit on the U-profile or O-ledger.
- Perforation: The anti-slip surface should not be so clogged with concrete residue or paint that slip resistance suffers.
- Corrosion: Pay attention to the galvanisation. Superficial discolouration is normal, but rust-through on the profile edges is an exclusion criterion.
Aluminium access decks & combi decks: lightweight with function
When it comes to quick access within the scaffold, aluminium access decks with an integrated ladder are indispensable.
- Advantages: Low weight saves the fitters' strength and speeds up assembly and dismantling.
- Maintenance note: On combi decks with a plywood insert, the timber panel must be checked regularly for rot or cracks.
- Condition of the ladder: The hinges and the locking mechanism of the integrated ladder must move freely and work properly.
Timber decks: the cost-effective alternative
Timber decks are the most affordable solution compared to steel and aluminium, but are subject to the highest wear.
- Important: Pay attention to the marking. Only scaffold boards with building authority approval and the corresponding stamp guarantee the required load-bearing capacity.
- Wear: Splintering edges or deep notches massively reduce the structural values.
CETRAC check: when must a deck be taken out of service?
A deck must be replaced immediately if:
- Permanent deformation: a deflection remains visible even when no load is on the deck.
- Cracks: cracks are visible in weld seams on the claws or in the aluminium profile.
- Missing lock: the anti-lift lock no longer engages properly.
FAQ on used scaffold decks
Yes, provided they have been inspected by a specialist company like CETRAC. We check every one of the more than 98,000 decks in our stock for structural relevance and mechanical integrity before they go on sale.
That depends on the work. For painting work, load class 2 or 3 (150–200 kg/m²) is often sufficient, while for masonry work or material storage, steel decks of load class 4 to 6 (300–600 kg/m²) are recommended. You can find out more about load classes here.
As a rule, no. Decks must exactly match the frame system (e.g. Layher-compatible or Plettac-compatible), as the hook-on systems (U-profile vs. tube support) vary. We are happy to advise you on the compatibility of our current stock.
Look out for severe deformation of the longitudinal profiles and check the condition of the hook-on claws. If the deck no longer lies flat or “rocks” on the ledger, it should be replaced.
