As we see it, the best long-term solution is therefore to replace aluminium with fibreglass composite which is resistant to gases like hydrogen sulphide,” says Kenn Overgaard.įiberline is currently experiencing a surge of interest in its composite planks. In no time at all, hinges and fittings also become heavily corroded. But not only aluminium planks are affected. “The impact of Lynetten’s harsh environment on aluminium and galvanized structures is visible everywhere at the plant. Lynetten’s project manager Kenn Overgaard has no regrets: Right solutionĪ decision was therefore taken to replace 1200 m² of heavily corroded aluminium planking with new HD Planks from Fiberline. The air inside the tanks is filled with hydrogen sulphide and other aggressive gases, and conventional materials buckle under the strain, with considerable risk to safety. The covers for the aeration tanks at Copenhagen’s Lynetten sewage treatment plant have to meet very tough requirements. The existing planks were worn out with corrosion – the new ones will last the course. This is the opinion of Yakka Gear, and hopes it will be helpful to shoppers make better informed decisions.One of northern Europe’s largest sewage treatment plants – Lynetten in Copenhagen - replaced aluminium planks with composite planks from Fiberline. Planks are one of the first things on a worksite to go missing, and you would hate for that to happen after spending your hard-earned money.ĭisclaimer: Yakka Gear does not offer legal advice and is not responsible.

Yakka Gear recommends looking for aluminium fixed length planks, with aluminium and rubber treads on both sizes, rated to 3m max span over 250kg, and removable end caps. Extendable planks may not be suitable for ramps either as this requires running the plank on an angle. #5 Fixed length plank vs extendable (telescopic) plank?įixed planks provide a solid stability whereas an extendable plank tends to wobble. Too heavy, if not galvanised it will be prone to rusting in the weather, short life. Lacks grip, too heavy to carry, absorbs moisture, can be brittle and prone to snapping or breaking down in the weather, splinters, short life. Lightweight and sturdy construction, long life, weather resistant protection. Here is a quick breakdown of the pros and cons of different materials. Yakka Gear recommends favouring the max span length first so you require less gear, and then consider the kg ratings to ensure it meets your requirements. Pro-tip: Using the right plank clamp may help evenly distribute the weight across both planks and reduce the flex on the planks. Note: Reducing the span may help increase the strength of the planks. Weight ratings may vary based on the max span length.
This means you will not have to run so many planks or supports if it is 3m vs 2m. Max span refers to how long you run the plank before it needs support again. It is important not to leave the newly cut ends exposed without endcaps, because it does a few important things: prevents rubbish from filling inside the plank, prevents sharp exposed ends, and provides a visually easier object to see so you do not hit or walk into it.įor aluminum planks, generally speaking ratings range from 1.8m up to 3m max span. This way you can cut the plank to the required size for the job at any time. Welded end caps are not designed to be removable and for this reason Yakka Gear recommends you will want to select screw or pop rivet end caps. The end caps can either be attached via pop riveted, welded, or screws. To answer this question you need to consider how the plank endcaps are attached to the aluminium extrusion. #2: Can the length be customised or cut to size? Yakka Gearrecommends choosing a plank with all of the above, meaning a plank with both aluminum pressed treads and rubber treads, and making sure the grip is on both the top and bottom of the plank. Some planks offer a completely smooth surface some planks offer a pressed tread into the aluminium extrusion and some planks offer rubber treads (either on the top side, or on both sides). It is important to note that having grip is important to both your stability while standing on top of the aluminium plank, and also under the plank for the surface the plank is touching. #1: Does the plank have grip and to what extent? Here are 5 short must-know tips you should consider before committing to your purchase.
