English to Italian Tech/Engineering Construction / Civil Engineering descrizione aziendale - t

The company offers a wide range of products, such as cut and bent reinforcement (couplers, tailor made and trailing end fabric); reinforcing mesh; concrete accessories (reinforcement spacers, slab accessories, bolts boxes, joint filler boards, crack inducers and void formers); concrete repair products; waterproofing products; fixings; formwork products (formwork tie system, formwork accessories, screed chairs and screed rails); brickwork products; geotechnical products; concrete finishing tools; diamond blades; drill bits; hand and power tools; and light construction equipment (mixers, compaction plates, screed equipment).

"Screed rails" dovrebbero essere "binari per massetti", ma non saprei proprio come tradurre "screed chairs". Ho trovato delle immagini per capire cosa sono, ma non so come renderlo in italiano.

Grazie per i vostri suggerimenti.
