For fixed working widths to be laid over long distances the SB30 is the ideal choice. At a basic width of 3,00 m this screed allows to be widened up to 13,50 m and at least 16,00 m using hard boxes of different sizes available. A tamper together with a dual vibration, which can be used separately or in combination, is the guarantee for best results in compaction. Hydraulically extendable end parts can be used for matching different working widths when laying. On special demand the SB30 is also available with electrical screed heating.
