Fire rated gates (hinged on vertical axis, named also MAGNUM) called hinged to differentiate them from the sliding ones, generally close large openings in the fire partition walls of factories, industrial warehouses, public car parks, shopping centers, trade fair pavilions and similar buildings through which equipment, forklifts or bulky means of transport must pass.
It must be said that fire rated hinged gates are heavy and not suitable for being opened several times a day. In case of frequent traffic it is advisable to keep them normally open, held in position by electromagnets controlled by smoke and heat detectors. In the event of fire electromagnets will release the leaf/leaves which will close on their own as they are equipped with overhead doorclosers.
Fire rated hinged gates kept normally open can be installed coupled with rapid opening gates to avoid air drafts or create a thermal barrier or with other shutters for different desired performances
The fire rated hinged gates are available EI 60 and EI 120 , single or double leaf, with a choice of a metallic tubular frame section 90 x 90 mm. or a “Z” corner frame. To see which type can be suitable on a specific wall opening, it must be checked if the leaves of the gate once installed con be opened completely, considering for the choice of the frame if it should stay within the wall opening dimension or partially or completely beyond it, see detailed drawings of proposed frames following in this section
The overall dimensions of the gates are specified in the forms in the DOWNLOAD area.
Due to their manufacture to one-piece leaf and their weights for installation, hinged gates reach a higher unit price per square meter and a larger opening encumbrance if compared to sliding gates, for this reason they are necessarily used only when the specific situation in the construction site does not allow the installation of sliding gates.
Metal fire rated hinged gates compliant with EN 16034 and EN 13241 standards, CE marked, to be kept normally open or closed, to be placed on masonry walls or on partitions having a metallic structure covered with fire rated plasterboard slabs or on partitions composed of fire rated sandwich panels reinforced externally with an insulated tubular supporting structure.
Tubular frame section 90 x 90 mm. or press-bent steel profile high-rersistance “Z” shaped on 3 sides with holes for fixing with expansion bolts or screws (not included).
Panels made of double sheet metal casing with special fire rated core, total thickness of 75 or 100 mm. with 2 extra strong hinges per leaf or 3 if the dimensions require it.
For automatic reclosing, 1 large hydraulic overhead doorcloser per leaf with adjustment of opening force, closing speed, final stroke. For very large dimensions, additional return spring or booster spring depending on the case. Self closing so guaranteed with doors open at 150°, for wider opening if necessary helped by additional push devices for the self-closing.
Thermo expanding gaskets placed on the vertical sides of the frame and on the lower and upper sides of the leaves and in the central rebate in case of double leaf gate.
Lock and cylinder both sides cylinder with keys, pair of handles with steel core covered in black nylon or stainless steel with plates. The double leaf gate also includes the closing regulator and in the secondary leaf a mortise counterlock with self-locking device for the closing in the frame at the top and in the floor socket at the bottom.
Gates made without floor thresholds (unless differently requested or offered) within the dimensions in the fields of direct application of standard EN 1634-1 up to single leaf cm 333 x 333 H and double leaf 594 x 423 H and in larger formats in extended application according to standard EN 15269.
Finish with thermo hardened epoxy-polyester powders, color RAL 7035. Other shades available to extra cost. On request, manufacturing of frames and leaves in AISI 304 or 316 stainless steel.
Metal plate with identification data and CE marking affixed to the gate in compliance with legal requirements. Accompanying documentation: installation, use and maintenance instructions, DoP declaration of performance.
Approximate weight 55 kg/square meters.
Packaging on disposable stands.
Doors to be installed on a plumb and square fire rated wall.
Indoors use in environments without strong air drafts and low traffic.
Assembly to be carried out by specialized personnel.
The 2 types of frame available are illustrated in detail below. When asking for offers of hinged gates it is necessary to indicate whether the dimensions given are those of clear passage LN x HN or external frame LT x HT.
It is also better to indicate the preferred installation between “within the wall opening” or “beyond the wall opening”, as the remaining net passage changes, see the following drawings.
In the case of fixing within the wall opening, it will be necessary for the purchaser, after installing the door, to cover the frame on the side opposite the hinges with an insulating material, for example brickwork or fire rated plasterboard or calcium silicate boards fixed on an insulated metal substructure.
Furthermore in case of fixing within the wall opening: it is advisable to consider sufficient air space between wall and frame based on the verticality, horizontality, straightness of walls and ceiling, squarness of corners. It is to check also that the floor is not inclined and that there are no obstacles in the entire area affected by the leaves while opening. Carry out the survey with the laser. Also take into consideration that as the dimensions of the gates vary, the dimensions of the doorclosers or other self-closing devices may vary, therefore in walls adjacent perpendicular to the gate it may be necessary to create recesses to house the accessories in order to open the leaves at 90°. To avoid creating recesses in the walls, it is possible to reduce the size of the gate by increasing the air. If in doubt, let us have complete information before ordering gates so to check your specific case
