Optimisation of manoeuvring and storage space
HINGE DOORS IN STAINLESS STEEL -Bifold door without bottom guide railsSafety, cleanliness, hygiene are fundamental characteristics of the working environment, especially in the food and chemical sectors.
Moreschi stainless steel doors with double wrap without bottom guide are the ideal answer to these needs.
Designed, produced and installed by Moreschi professionals, they ensure a high level of quality, help to optimise manoeuvring and storage space, and thanks to the absence of a lower drive, reduce maintenance costs.
TECHNICAL PRODUCT INFORMATION
The bifold door is made up of 52 mm thick Leaves with respective internal perimeter frames in 20/10 thick galvanised steel profile; the Leaves are completely covered with smooth stainless steel sheets; the external surface is completely smooth with a satin effect . The insulation is guaranteed by the injection of self-extinguishing polyurethane foam according to DIN 4102 class B2, with a density of not less than 43/45 kg/m³, obtained by means of an expansion process under press which ensures a high degree of thermal insulation. We prevent scratches by applying adhesive film to be removed after installation.
The upper guide with the relative fixing brackets is in stainless steel made to our design and is press-folded (Monorail type) with thickness. In this way the door is already prepared for possible motorizations. The guide is equipped with stainless steel trolleys with four bearings that guarantee easy manoeuvring. This type of door does not need a lower guide because the two lateral posts, in stainless steel section and the upper guide give rigidity to the structure. It is anchored to the wall, thus forming a real frame for the door itself, guaranteeing a high degree of stability.
On the ground, and in the centre of the wall compartment, there is a slipper in aluminium or stainless steel alloy where the pins with the relative stainless steel olives are inserted when closing; this gives a guarantee of closure and safety.
The hinges, with frontal fixing, are in stainless steel. The insertion of self-lubricating bushings and thrust bearings allows maintenance to be reduced to a minimum. Stainless steel pin with anti-fall and milling system to ensure internal fixing. This system prevents it from slipping off, with the consequent opening of the door.
On the internal side, at man height, there are 4 fixing points stainless steel pins, as well as a central clutch to adjust the handle. The opening and closing of the door is facilitated by stainless steel handles.
Stainless steel rods with two closing points, slide in the passages where Teflon supports are inserted to guarantee precision, remarkable sliding and silent movement.
The sealing gaskets between sash and door, with crossed double leaf, are in EPDM (anti-aging) natural rubber to guarantee maximum closure; moreover the space between the sashes is 50 mm (anti-crushing) on all versions: manual, motorised or motorised as per current regulations. In the upper and lower part the closure is guaranteed by a double needle gasket with pre-cut parts to guarantee the possibility of adjustment on non-planar floors. Finally, the vertical and horizontal gaskets are thermally welded together to create a single profile that guarantees tightness and thermal insulation. Prepared for motorisation on request with special upper guide.
