Buy spacers for reinforcement – secure standard-compliant concrete cover
Reinforcement spacerare prescribed tools in reinforced concrete construction. You carryreinforcing steelandstructural steel matsExactly at the required distance to the formwork – and thus secure the concrete cover according to DIN EN 1992-1-1 (Eurocode 2).

Why spacers are indispensable for reinforcement
Theconcrete cover– The distance between the reinforcement surface and the outermost concrete surface – is one of the most critical quality variables in reinforced concrete construction. She protects thereinforcing steelBefore corrosion, secures the bond between concrete and steel and guarantees structural fire protection according to Eurocode 2.
If the concrete cover is not correct, there is a risk:
- Early reinforcement corrosion by chloride or carbonation attack
- Concrete cover spacing (concrete blasts)
- Understanding the minimum fire protection requirements
- Structural damage with considerable costs in stock
Spacers take on this safety-relevant task mechanically, reliably and cost-effectively. In the design standard DIN EN 1992-1-1, they areprescribed toolsrequired.
Types of spacers – plastic, concrete and steel
Depending on the exposure class, component geometry and formwork, the right material is chosen.
plastic spacer
The most used type. Suitable for exposure classes XC1-XC4. Available as a wheel spacer, clamp spacer, ring spacer and surface spacer (chair). Heights: 10-80 mm, grid 5 mm.
Concrete Spacer
Made of cement mortar, same W/Z value as ambient concrete. Ideal for exposure classes XD and XS (chloride attack), tunnel construction and waterproof concrete (WU concrete). Heights: 15-80mm.
Steel Spacer
Galvanized wire spacers (snails, stars, U-brackets) for ceiling reinforcement and wall formwork. Not suitable for exterior components with high exposure class. Heights: 10-50mm.
| Type | Material | heights (mm) | Typical application | exposure class |
|---|---|---|---|---|
| wheel spacer | Plastic | 10/15/20/25/30/40/50 | Foundations, walls, ceilings | XC1–XC4 |
| spacer (chair) | Plastic | 30/40/50/60/70/80 | Floor slabs, upper mat layer | XC1–XC4 |
| clamping spacer | Plastic | 15-50 | Walls, supports (clamps on rod) | XC1–XC4 |
| concrete block | cement mortar | 20-80 | Aggressive milieu, Wu concrete | XC–XS–XD |
| Wire spacer (screw) | galvanized steel | 10-40 | ceilings, interior components | XC1–XC2 |
Applications in civil engineering and civil engineering
- Foundation plates and strip foundations:Plastic wheel spacer under the lowest layer of the mat, concrete chairs for the upper layer on thick panels.
- Walls and Supports:Clamp spacer on vertical bars, fuse on both sides on formwork and reinforcement basket.
- Reinforced concrete ceilings:Surface chairs (plastic or steel) for the upper reinforcement layer, wheel spacers for the lower position on the formwork.
- Civil engineering and bridge construction:Concrete spacer for chloride exposure (XS/XD), special tunnel components with high minimum coverages ≥ 50 mm.
- Precast production:Precise plastic spacers for consistent quality in time.
when combined with machine-made reinforcement elements – for example after theBending and CuttingIn the factory – spacers can already be installed on the bending list at the factory, which greatly simplifies construction site logistics.
