Steel hoppers are manufactured from different materials as selected by the customer:

A)  All stainless steel.
B)  Stainless steel doors and chutes, with mild steel frames and hoods.
C)  All mild steel.

All of these hoppers are normally supplied with cast aluminium handles, and all mild steel components are hot-dipped galvanised after manufacture.  Hoppers have double-skinned doors, incorporating a layer of calcium silicate board for greater fire resistance, and anti-vandal hinges.

Ealing Hopper

The Ealing is the largest hopper which can be installed in a 600mm i.d. chute, or it can be used as a direct feed hopper.  The large capacity of the Ealing allows residents to use large rubbish bags.

Argyle Hopper

The Argyle is intermediate in size between the Ealing and the Code Mk11/64. It is also suitable for use with 600mm i.d. chutes, or as a direct feed hopper.

Other Hoppers

Hoppers can be specially made in other sizes, to fit non-standard openings or old refuse chutes.

For situations where height constraints make hoppers impracticable, side-hung, self-closing doors can be supplied.

Appearance and Finish

Stainless steel hopper doors are normally supplied with a dull polished finish.  Mild steel hopper doors are normally powder-coated silver grey, but other paint finishes are available on request.

Installation

After removal of the door from the frame using a special screwdriver, a steel hopper is normally fixed by means of bolts in the side of the frame, into inserts in a concrete unit or brick wall.  Bolts used for fixing in concrete units are 10mm in diameter, and those used for fixing in walls must be at least 10mm diameter.

Accessories

1)  Face plates in either stainless steel or mild steel can be supplied for front fixing of hoppers.

2)  Locks can fitted to hoppers.

3)For hoppers fitted into brickwork openings, galvanised mild steel hopper extensions can be supplied, where needed.  Extensions are available in any length from 150mm to 600mm.  The foot of the extension should not be less than 75mm above the top of the bin.

For fixing to True-Crete concrete units  remove vandal-resistant hinge pins using special screwdriver and take off the door. Place the frame and hood into position and fix by means of bolts through the holes in the frame and into the inserts in the concrete.replace the door.
For fixing into brickwork, proceed as above, but inserts must be provided in the brickwork for this purpose.  An alternative method is by using building lugs, which can be supplied with this hopper, and fixing in the normal way.
The brickwork opening required is 455mm wide x 290mm high.  Where the thickness of the bin room wall exceeds 100mm, any Code hopper requires an extension.
