Stira wraparound hinge1/7/2024 ![]() We manufacture most of the the metal parts of our stairs in our factory, we make them out of real steel, we don?t use cheap alloys. This is another strong reliable construction grade timber. The inner and outer frame of the Stira stairs is made from White Deal sourced from managed forests in Northern Europe. The metal step will gradually distort more and more over time which will go on to affect other joints in the ladder. While the timber is very strong it remains flexible, and unlike with metal ladders when the timber steps bend under weight they will return to their natural state. Using a strong timber has many benefits over a metal ladder. We use SAPS grade timber which is a hard wearing timber which feature minimal knots or defects. That’s almost half the requirement for a passive house.

The hinge on the first fold of the ladder is under the most pressure, over time the hinge can slowly be pulled out of the timber by the weight that is put through it. This hinge on the bottom fold on the ladder. As we don?t attach the ladder directly to the trapdoor this allows the standard lid of the Stira to be replaced with an alternative lid of the customers choice. The inner frame of the Stira that attaches the ladder to the outer frame is unique to Stira, this rigid frame allows us to vary the opening size of the Stira making it much bigger or smaller without affecting the mechanics of the stairs. The outer frames importance is often overlooked but it is essential as this frame will be carrying the weight of the stairs through the hinges and linkage arms, which are the main load baring parts of any folding stairs or loft ladder. The Stira folding attic stairs features a substantial outer frame which is 108mm x 32mm, this deep frame gives the Stira a solid attachment to the joists in the attic. This item can be added at a reduced rate with your loft ladder purchase. This gives you added security when getting towards the top of the loft ladder. ![]() The deluxe loft handrail for the Stira Loft Ladder sits in the loft and is secured to the loft floor.
