Headwalls with Orifice Plates

Althon have recently supplied several SFA headwalls (headwalls that are compliant with Sewerage Sector Guidance) factory fitted with bespoke orifice plates. Orifice plates can be manufactured in either galvanized or stainless steel and they are designed to restrict and regulate the flow of water. We can manufacture the orifice plates to suit multiple openings or one opening in any position required on the plate. 

In this instance the customer was using a 1200mm ID pipe coming into the back of the headwall and wanted 3No. 73mm, 87mm and 103mm holes in the orifice plate to restrict the flow. We also then added stitch welds to strengthen the plate.

For more information on orifice plates please visit Orifice Plates, email us sales@althon.co.uk or call us on 01603 488700.

Welded and Powder Coated Handrail  

We can factory fit Handrail to any of our precast concrete headwalls and our standard is Galvanised Kee Klamp ® size 8 fittings which complies with Civil Engineering Specification for the Water Industry (CESWI) 7th Edition Clause 2.60 Handrails & Balusters & The Engineering Equipment and Materials Users' Association (EEMUA) Publication 105 7th Edition Factory Stairways, Ladders and Handrails.

However on request we can also make welded handrail which can then be powder coated in any RAL colour that is required. For more information on using a different handrail please email sales@althon.co.uk

Bespoke Headwall and Grating 

The headwall and grating shown are a bespoke design based on a clients sketch for a project in Downderry, Cornwall. The headwall only required 1 wingwall due to the customer wanting a concrete footpath on the right hand side that the headwall would then butt up against. The trash screen required a working platform for maintenance purposes and is manufactured to BS EN 1090 standards.

For more information on the types of headwalls we offer please visit our headwalls section or if you cannot find the headwall you are looking for use our design form or email us sales@althon.co.uk
