The supports have full-surface floor seals. The seals are not simple hose seals, but are made of EPDM/foam rubber and are not glued. They have a long service life and are insensitive to dirt and vandalism. If necessary, they can be replaced by hand.
Our stop logs are subject to surface treatment: the lowest beams are powder-coated blue. The others are anodised. This is not primarily decorative, but rather functional. On the one hand it makes assembly easier, on the other hand the surface protection prevents any cold welding of the aluminium logs during storage.
