As Chichester Free School prepared to welcome students to its new campus, it wanted a top-class perimeter protection solution to keep its pupils and its property safe. Working with Heras, the school installed a bespoke solution that combines Tangorail safety railings and gates with Heras welded mesh fencing. Read the full story here. How to install, service and maintain metal railing fences Mechanically-cleaned bar screens have smaller opening sizes of 0.25 to 1.5 inches (6 mm to 36 mm). The bars can be steeper at 0 to 30 degrees as employees don’t have to rake the debris. For a smooth and continuous operation, it’s important to prevent clogging. The flow of water must remain steady at all times, which is why we have different types of bar screens today. They differ on the cleaning system.

These railings are hard to climb over and effectively restrict people from climbing through the railing gaps. The railing bars are also positioned so that you can still have a clear view through the system without obstruction. Tangorail’s bow-topped design meets the British Standards Institute’s BS EN 1176 standards for playground fencing, with protections against entrapment and rounded edges to protect against injuries. RoSPA guidance for playground railings Our experts’ deep understanding of the features and specifications of our inlet works equipment means we can guarantee that each item will meet or beat customer requirements over its anticipated design life. We also aim to deliver on time, every time, thanks to our investment in standardisation. Chain-driven screens use screens for cleaning. The rake can go up or down, depending on if the flow of water is from upstream or downstream. A small advantage is that the equipment requires little maintenance at all. Small plants with only a few screenings can also make manual bar screens work for them. Mechanical Bar ScreenThe horizontal slot, normally the mortar bed, can be cut using a twin diamond blade chaser with vacuum attachment, an angle grinder or a mortar chisel. Insert a further bead of HeliBondover the exposed HeliBar, finishing 12mm from the face, and ‘iron’ firmly into the slot using the HeliBar Insertion Tool. Manual bar screens need frequent raking to remove the accumulated waste. As you would expect, this method is labor-extensive.

Before you start, be aware of outside lighting – in many cases, the wiring from fixtures is hidden within the joints of your wall, so make sure you isolate the circuit before chipping away.If you are repointing around window or door frames, work carefully when clearing these joints as being heavy handed could affect the way that fixtures open or close. New facilities almost always have mechanical screen cleaning systems as their primary device. They have more advantages than disadvantages. For this reason, manual bar screens are disappearing from industrial settings. These types of bar screens have a much larger area submerged in water. This allows for less frequent rakings, but it’s still time-consuming. They shouldn’t be larger than 3 meters, though, for convenient raking.

As the preliminary or first step in the wastewater treatment process, bar screens serve a crucial role. The other equipment depends on them to do their job well. As such, you need the right wastewater bar screen for your facility.

Marking your perimeter with metal railings

They have four principal types: chain-driven screens, reciprocating rake, catenary screen, and continuous belt screen. Pro tip: Make sure all the excess mortar is removed. This way, you’ll avoid air or water in the space behind it and will prolong the life of your wall. Your railing system will be provided with the necessary fixings and posts ready for construction. If each end of your railing structure does not join together you will need to use an additional post. Railing bays possess a 2.75m. The railings are also supplied with a polyester powder coated finish which makes them more striking, as well as more resilient to vandalism damage, weathering and general wear. Don’t worry about excess at this point. Work on a few rows at a time, beginning by filling the bed joints and then the head (vertical) joints.
