Retractable security door SILEA
SILEA construction
Internal vertical reinforced bars made entirely of stainless steel.
Guide made of aluminium profile on top side.
Vertical aluminium bars which cover the stainless steel and the spigots of leve.
Lock made of stainless steel with locks on 3 different points (a central hook and two spigots which lock on the upper and bottom guide).
Sliding rollers technoplastics, made of self lubricating material, with low friction factor, high resistance to wear and tear, to deformation and to high or low temperatures.
Leve, made of high durable steel galvanized and painted. The special shape of their parts makes them particularly resistant to cutting.
Profile for alignment of wall imperfections.
The bottom guide facilitates the noiseless movement of the vertical bars, while the perfect design prevents the removal of the bars.
The connecting angles for the profiles, the points of contact of the leve and the points of friction on the upper and bottom points of the bars are made of durable self lubricating material (epoxy resin).
The points which hold the Leve on the bars are not visible.
