How do you recognise a ‘heavy duty loft ladder’?

Anyone can say they offer a heavy duty loft ladder, but what does it really mean? Well, the first thing to look for is whether or not the loft ladder was constructed and tested in accordance with EN 14975. This European standard makes sure that the loft ladder meets a minimum load capacity of 150kg, as well as a variety of dynamic and static load tests. EN 14975 also defines the loft ladder geometry to ensure the safety of its users.

Conformance to EN 14975 is a great start, but it defines the minimum requirements. When choosing a heavy duty loft ladder, you want a product that exceeds these standards. Look for high strength loft ladders that are designed to meet a higher load capacity. Such as our Supreme and Elite loft ladders, which have a load rating of 200kg per tread and an overall capacity of 500kg/m2. Also check that they come with a warranty. In addition, wide steps are often beneficial – read our Wide Loft Ladders article for more information and advice on this subject. Finally, choose a heavy duty loft ladder that is rigid and does not flex during use.

There are several styles of heavy duty loft ladders, including sliding aluminium ladders, folding wooden loft ladders or retractable loft ladders. Each have merits and cater for various budgets. For ease of operation and minimal protrusion into the space above the hatch, we recommend either retractable aluminium loft ladders or folding wooden loft ladders.
