Careful consideration to the following factors determine the channels design:
 

PROFILE

The channel edge details will depend on the floor finish, examples being tile, resin, or vinyl. Channels can be designed to provide vinyl one side and resin or tile the other if required.
 

WIDTH

Widths of channels will depend on the splash area below discharging equipment of appliances and should be a minimum 200mm wide overall for wash down installations. Widths are available in 50mm increments from the minimum 200mm overall width.
 

FALL

The excellent smooth surface finish of stainless steel provides a self-cleansing velocity of liquids at very shallow gradients, this being 0.75 m/s). Velocities below this figure require manual flushing. Typical gradients are 1% (1:100) for liquid waste, 2% (1:50) for water-borne solids. Please note that discharge capacities of both channel and gully will be reduced when conveying water-borne solids and the discharge of the drainage channel is relative to the flow rate capacity of the outlet.
 

GRATING

See 4000 series gratings section.
 

OUTLET

Options include connecting to a 5000 series gully, a trapped (plug-in trap) or untrapped Ø110mm/Ø160mm outlet spigot.
 

MATERIAL GRADE

See stainless steel information.
 

ACCESSORIES

For applications where heavy loads and/or thermal shock are anticipated, an expansion frame around the perimeter is recommended. The expansion frame is supplied factory tack welded to all profiles, except the Vinoseal 3051, by specifying the channel profile and adding the suffix letters EF eg, 3010EF. The expansion frame offers a true square strong edge for dressing-in resin and allows the floor finish to be separated from the channel, thus reducing the possibility of cracking under vibration or expansion.
