Harmer are well known for manufacturing the marketing leading range of rainwater handling and building drainage products. Now Rainclear offer the added convenience of buying them on a mobile responsive ecommerce website wherever you are and whenever you are ready.

The Cast Iron Range of roof drainage outlets are, as you would expect from Harmer, a high quality range suitable for most types of drainage application. The range features medium sump and large sump bodies, available with a variety of flow rate capacity to discharge the requirements of your building design, and an extensive range of loadbearing grates (load rating up to 12.5 tonnes). 

The crystallised nature of cast iron gives this material very high strength and robustness. It has a proven track record for its longevity and 100% recyclable-ability. Once installed these components resist impact damage even in exposed areas like heavy vehicle trafficked areas and at end of life can be returned to the furnace to make new iron products.

Cast Iron is not only inherently durable but can also be safely used with copper and lead clad roofs with less risk of bi-metallic corrosion. Harmer cast iron clamps and grates are also treated with a sherardizing zinc coating that provides an extremely hard wearing anti-corrosive finish.

The Harmer range, and the selection on the Rainclear website, offers a wide choice of standard drain body variations with spigot and threaded outlet connection and fully secured grating options. While the domical grates, made from UV stable polypropylene to ensure a long life, are designed to permit free flow of rainwater while preventing loose chippings and debris from entering the outlet, the flat circular and square grates are designed for differing levels and weights of vehicular traffic. 

Some of the options:

• Medium Sump: Vertical (spigot or threaded) & horizontal (threaded only) variations for connection to 50, 75 and 10mm pipework
  
  • The variety of circular and square grates are suitable for areas with vehicular access.
• Large Sump: deep sump for 100mmm & 150mmm vertical pipe
  
  • Threaded to 4” and 6” BSP
  • Use Harmer adaptors for connection to Cast Iron, HDPE, PVCu & stainless steel pipework
  • Range of grates including heavy duty ductile circular & Square grates suitable for areas with vehicular access.
• Flat grate: suitable for pedestrian or light vehicle traffic (excluding forklifts) – also designed for use with Modulock raised floor supports (also on the website) where concealed rainwater outlets are used.
• Square flat Grate: made of ductile iron for use in areas with vehicular access like care parks, factories and workshops.
• Double flange variable height: For use in loadbearing warn roof applications – allows fine adjustment for use with insulation thicknesses between 80-100mm.
• Extension pieces with adjustable height grates: For use in inverted roof and screed areas with pedestrian and vehicular traffic – waterproofing is achieved at the outlet body flange with the extension piece allowing permeable drainage into the outlet and use with varying thicknesses of insulation and roof finish.

“Harmer offer a range of accessories such as extension pipes, pipe adaptors and various grates to suit most types of roof construction. The range also includes two-way outlets.
