Circular Covers

 
  
 
Circular cover units are intended primarily for use on circular pits where the use of a circular cover simplifies forming the pit top.
 
A range of units are available with prefilled covers and frames encased on concrete surrounds;
these units are used on pits made from precast concrete pipes, or where on-site filling or pit rebate forming presents difficulties.
The concrete surrounds of encased frames can also be modified for use over square or rectangular openings.
 
A circular cover, when placed on edge, cannot pass through its frame opening and accidentally drop inside the pit.
This eliminates the danger of dropping the cover down the hole when servicing.
This makes circular covers invaluable for use on single openings over valves, machinery or deep pits where a
dropped cover could cause damage.
 
The design of GATIC circular covers utilises metal more effectively than can be achieved with the design of a square cover.
 
STANDARD CIRCULAR COVER UNIT FEATURES
 
The range of one-part circular units are available in Class B, D and E ratings in accordance with
Australian Standard AS3996:2006 and with the following distinctive features:
  •  Covers (Infilled): ribbed, dished casting design.
  • Covers (Solid Top): Non skid pattern top surface.
  • Frames: Three T-bar sections for bolted and leaded joints. 
Advantages of Circular Design:
  •  Covers cannot accidentally drop through frame openings.
  • Compared with square units, circular units require less metal for the same strength and are, therefore, lighter.
  • Modular cover and frame design allows full interchangeability between various covers within the same class rating.
