Retaining system - ST boxes

The Edilmatic retaining system ST Boxes is a simple and effective solution for the connection of façade panels to the structural frame of the building.

The system is made of:

There are four sizes of ST Boxes:

The Ultimate Limit State resistance of the insert is equal to 26,6 kN for all the types 

The system has the CE mark according to EN 1090. The boxes are labelled with the identification of the manufacturer and of the production batch.

The performances of the system are guaranteed only if the accessories and the presctiptions of the catalogue are fulfilled.

The ST boxes are coated with electrolytic galvanizing according to EN ISO 2081.

The ST Boxes are supplied complete with polystyrene pocket former, already inserted on the boxes. At the end of the casting procedures, by removing the polystyrene, recesses are created for the insertion of the anchoring accessories.

The system allows the connection of an element to a structure as soon as the crane approaches the element in its final location, as indicated in the mounting drawings.

To complete the connection, insert the bolt in the rear recess of the box, insert it into the anchor channel and lock with nut and washer.

The polystyrene recess former ensures that the ST Boxes remain below the top level of the panel, so the system is completely hidden.

The slotted hole on the ST Boxes allows a wide possibility of adjustment, even in case of positioning errors of the profile.

Thanks to the compact dimensions and to the special shape of the anchors, the performances of the ST Boxes are guaranteed at any point of attachment along the axis of the slotted hole.
