Uşor şi multifuncţional

AluStar este cofrajul cu rame din aluminiu versatil şi uşor, reprezentând completarea de sistem independentă de macara din familia StarTec/AluStar. Sistemul asigură o execuţie rapidă chiar şi fără macara. Cel mai mare panou 270/90 cântăreşte numai 65 kg. Acest lucru este apreciat atât de întreprinderile mici şi mijlocii, cât şi de cele mari, cu următoarele domenii de utilizare:

  • construcţii de locuinţe
  • construcţii industriale
  • şantiere fără spaţiu de amplasarea macaralei
  • lucrări de consolidare şi renovare
  • puţuri, canale, silozuri, rezervoare şi subzidiri
  • partiuri complexe
