Special joints - Import export

One of the winning features of the Hercules grate is the special PATENTED JOINT which allows for easy and fluid opening of both the internal and external doors, allowing for easy movement of the external shutters. HERCULES 2 – 4 consists of: 4-sided telescopic FRAME, made with 40x30mm galvanized steel vertical profiles, available in 18 variants to best adapt to every construction requirement. GRATED DOOR made with sturdy galvanized steel profiles measuring 60x30mm, while the crosspieces are made of 40x30mm tubing; and as a filler chosen from our aesthetic models. JOINT obtained through mechanical processing of solid steel and carefully welded to the tubulars/crosspieces. The upper joint has a steel nut applied as standard which, in the closed position, embraces the 16mm steel pin inserted on the frame/upper crosspiece. PIVOT HINGES Composed of a die-cast mortise structure within which the cut-resistant solid steel rotation pin, diameter 16 mm, is controlled

These joints are obtained by opposing two finger-shaped metal elements: each is fixed to its head, thus ensuring, thanks to a suitable interpenetration, continuity of the carriageway in case of expansion/shrinkage. Their static layout can act as a beam on two bearings when the finger rests on both heads or as a shelf when it overhangs a head. A specific device is needed, usually a gutter, to ensure the gap watertightness. Special attention should be paid to the alignment during the installation phase and to the head anchoring, especially in the case of shelf layout. Except for special arrangements, this type of joint permits limited transverse displacements. TIPOLOGIE: SFE 90/65 GP FE C
