{"product_id":"flat-oval-spiral-seamed-duct-with-flanges","title":"Flat Oval Spiral Seamed Duct with Flanges","description":"\u003cp\u003eA flat oval duct features a cross-section with flat, opposed sides and semicircular ends. Our Flat Oval Spiral Seamed Duct with Flanges combines the aerodynamic efficiency of circular spiral ductwork with a low-profile, space-saving oval design. It is ideal for areas with limited ceiling height, such as tight risers, restricted voids, or complex structural partitions. This elegant design supports high-capacity airflow while minimising pressure loss, noise, and turbulence commonly associated with rectangular ducting.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3 metre standard length \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe standard jointing method is with an oval coupling\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFits into shallow ceiling voids where round ducting is too tall, maintaining the high-volume capacity required for efficient HVAC performance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEngineered with a continuous spiral lockseam to reduce internal friction and minimise pressure loss compared to standard rectangular systems\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFabricated from premium hot-dip galvanised steel for great structural rigidity and long-term corrosion resistance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFittings supplied small end as standard to fit into straight duct\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eApart from stiffening requirements, flat oval ducts follow the same construction standards across all pressure ranges defined in DW144\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIn some cases, additional stiffening is required in the form of tie bars which are fitted in line with DW144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ducting Direct","offers":[{"title":"Default Title","offer_id":53962585964886,"sku":"FOSSDF","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0895\/0946\/2358\/files\/flat-oval-spiral-seamed-duct-with-flanges-830.webp?v=1779449288","url":"https:\/\/ductingdirect.co.uk\/products\/flat-oval-spiral-seamed-duct-with-flanges","provider":"Ducting Direct","version":"1.0","type":"link"}
