Vibratory Screed Bars

Vibratory screed profile by Enar, Altrad Belle and Wacker Neuson — a replaceable working part

A vibratory screed profile (screed bar, working beam) is an aluminium or steel section that comes into direct contact with fresh concrete. A drive mounted on the profile, or connected by a flexible shaft, puts it into 80–150 Hz vibration (standard EN 12649), which strikes off excess mix to guide-rail level and de-airs the concrete to a depth of 3–5 cm. Typical length is 1.5–3.6 m, depending on the number of handles. This is a wear part — the edge grinds down with every pass, so it is bought separately as a replacement once the original part in your screed wears out, bends or corrodes.

At NORWIT.PL we stock profiles primarily from Enar, Altrad Belle and Wacker Neuson — you can also buy them on the brand pages Enar, Altrad Belle and Wacker Neuson. This category rounds out floating vibratory screeds, alongside drive units and complete sets. Below: how to choose the length and material, and how to spot wear and replace a profile.

Types of vibratory screed profiles — length and number of handles

Profiles differ mainly in length and number of handles — that determines how many people operate the screed and how much surface a single pass covers.

A profile that's too short increases the number of passes and the risk of visible joints between strips, so length is chosen slightly greater than the working width. See the full range in the parent category floating vibratory screeds.

Aluminium or steel profile for a vibratory screed

Material choice comes down to the scale of the work. Aluminium dominates in modern screeds because of its weight; steel matters more where edge resistance to damage under daily work counts.

How to choose a profile that fits your screed — brand and mounting

A replacement profile is matched to the brand and model of the drive you already own, because mounting points and the section's cross-section differ between manufacturers and series. An Enar profile won't usually connect directly to a Wacker Neuson or Altrad Belle drive without modification.

The range also includes profiles matched to other manufacturers' systems, for example a profile for a Betontrowel Euroscreed screed — choosing the right one depends on the specific drive system, not just the length of the part.

When to replace a profile — signs of wear and DIY installation

Wear shows up as a chipped or bent working edge, wear grooves on the underside, play in the drive mount, and streaks instead of an even finish after a pass. Under intensive daily work a profile may need replacing after a season or two; with occasional use it lasts several years. A steel profile should also be checked for corrosion.

Installation starts with disconnecting the fuel supply or power and unscrewing the bolts holding the worn profile — usually 2 to 6, depending on length. Fit the new profile in the same position, keep the working edge aligned parallel, and tighten the mounting bolts crosswise. Finish by checking it runs correctly at idle and that the profile doesn't touch the drive housing.
