Our Covers

Our Glass Reinforced Plastic covers are specialized for the purpose, and we design and manufacture a wide range of GRP covers. Have a look around our navigation menu to the right, and decide what cover is best for you. Of course, all of our covers are specially designed and manufactured; whatever you see can be adapted for its use in your project. 

For any inquiries regarding our GRP Covers, get in touch through our phoneline on our About page, and we can provide a quote for you- the time that the quote will take is dependant on the complexity of your requirements, so please keep that in mind. 

Inlets

No two inlet works are the same- each one needs to have covers specifically designed for it. Whether the covers are to fit a newly built inlet works or are to be retrofitted to an existing structure, Corporate Engineering can develop a design concept to suit.
 

For new works, we are happy to offer advice on the inlet work’s design to enable efficient covering to minimize odor escape. By following some simple guidelines, the efficiency of the covers can be increased dramatically while keeping costs to a minimum.
 

Even the most complex inlet works can be retro-fitted with odour containment covers. Corporate Engineering can visit the site and lead you through the preparation work that is required to allow GRP covers to be installed.

Where access for operations personnel is required, cover panels can be designed to support imposed loads of up to 5kN/m2. Slip deterrent surfaces and handrailing are normally supplied in these areas.

 

Corporate Engineering can provide examples of covers to:

  • Inlet wet wells

  • Screw pumping stations

  • Inlet screens

  • Distribution, by-pass and flume channels

  • Grit removal lanes

  • Fat Oil Grease and Grit (FOGG) lanes

  • Distribution Chambers

Beam and Infill

The beam and infill system offers a flexible solution to covering any shape of tank or chamber. The BI system pans up to 22 meters and is totally self-supporting. The system allows for covers to be fitted without the need for emptying or cleaning the tank as no access into the structure is required. As this is a modular system, covers can be built directly onto the structure, unlike other covers that need to be built on the ground and then lifted into position. An advantage on sites where space is at a premium. Corporate Engineering offers a full range of access manways, inspection and mixer hatches to suit your requirements. Flat areas for walkways can be included around hatches and equipment (if required). Different access loadings can be defined by contrasting colours. Covers can be manufactured to any British Standard or RAL colour. Beam and infill covers are supplied as a kit of smaller components making them easy to transport and install. Covers can be containerised for export.

Chamber

Pump chambers and wet wells can be quite complicated and difficult to cover effectively. Corporate Engineering can design covers that provide access for the safe operation and removal of pumps and other equipment while accommodating pipework penetrations and guide-rails etc.

Conical

Corporate Engineering can also supply conical covers. Where simple odour containment covers are required and access onto it is not required, conical covers can be an economical option. Corporate Engineering are currently redesigning their range of conical covers and we hope to be able to offer covers to suit tanks from 5 to 16.22m diameter in the near future. Conical covers are now available up to 11.1m diameter, and covers up to 15m diameter are coming soon. Should you need more details regarding this, please do not hesitate to contact us.

 

Our Conical covers are designed in accordance with WIMES 8.05 and the relevant utility specifications. These also include standard duty (0.75kN/m2) to BS EN-1991-1-1:2002. Our structural design is verified using the latest FEA software, and any colour from the RAL or BS4800 ranges. This includes robust cover segments that are easy to handle and assemble. We can provide efficient stacking for economical transport, and access manways - hinged and lockable c/w removable stainless steel safety grille. The conical covers feature mixer and aerator hatches, and flanged upstands for odour extraction instruments. Air inlets c/w bird or insect mesh.

Sliding

For some applications, inspection hatches sometimes do not provide sufficient access to the contents or equipment below. Corporate Engineering have supplied many sliding covers to such areas. Sliding covers can solve some operational problems but can create several others. Odour tightness and safe operation are just two issues that need to be considered. Corporate Engineering can advise the best solution for each application. 

 

CEL only use components that can survive the demanding conditions found on all sewage treatment works. Any steelwork is stainless steel (Grade 316) and all running gear is similarly corrosion resistant.

Hybrid

Corporate Engineering’s standard GRP covers can be modified to incorporate fabric covers.

Fabric covers have been developed to meet the needs of operations personnel where large areas of a cover need to be opened for inspection and to give the operators a clear view of the process.

The operation of the fabric section is designed to be a one-person procedure and to require minimal effort. With only 3 moving parts, maintenance is kept to a minimum.

When closed, the fabric is tensioned to prevent ponding and ice formation.
