Rack Shutter


Rack shutters are a very widely used system for intercepting bulk material under discharge hoppers and conveyors. They are characterised by their intrinsic simplicity that has promoted their widespread diffusion. Metalmont shutters are suitable for the transport of cereals, seeds and their derivatives.

In designing these products, Metalmont has scrupulously applied the latest and most stringent standards with regard to operator safety, reliability in the most arduous working conditions and construction quality, with the aim of reducing energy consumption and maintenance costs.

Metalmont shutters are also available on request with ATEX 22 certification. The standard operating temperature range is 0 to 40 °C.

Information on our past installations and customer portfolio is available on request.



The range of Metalmont shutters consists of 4 models:
Model Width Length
SCM 040 170 500
SCM 060 240 500
SCM 120 340 700
SCM 200 430 800
The shutter consists of a robust body in 3 mm thick construction steel sheet with galvanised Z275 coating. Inside it features a wear- resistant, galvanised steel closure blade of thickness 6 mm, which is operated by means of a M2 Z18 rack-and-pinion drive.

The shutter can be operated with manual, chain or motorised drive, and can be equipped with mechanical or inductive limit switches according to the customer’s requirements.


Various types of discharge hopper are available on request.

Metal joinery components: in addition to specific accessories for the correct installation of its machines, Metalmont is also a long-standing supplier of more general but equally useful plant access and structural solutions such as staircases, rest platforms, inspection platforms, walkways, frameworks and bracketing of all kinds, from simple brackets to backstays for supporting long sections of piping, shelves and stands.
