Load-bearing structures for interior and exterior stairs, with treads prepared for timber, stone or plate.
Stairs cannot be corrected afterwards — the rise has to be identical on every step, or people will trip in that house for the rest of its life. So we measure the finished floor, not the screed, and ask for the thickness of the covering before any steel is cut.
Load-bearing structures for interior and exterior stairs: straight, with a landing, spiral and cantilevered. Treads are left prepared for timber, stone or chequer plate.
A central beam with treads on cantilevers. It looks light, but needs a heavier structure and precise fitting.
The classic and most economical solution, with beams on both sides. It carries the greatest load.
Around a central column, where there is no room for a straight flight. From 1.2 m diameter up, below that they become unusable.
External stairs with a stainless handrail, galvanised and powder coated. After two winters by the sea there is no sign of corrosion.
By the sea it is the protection that decides, not the thickness of the steel. Before we quote, we ask where the structure will stand and how far it is from the water.
The strongest and cheapest option, but only with galvanising and powder coating. Left unprotected on the coast it rusts within a single season.
For handrails and railings by the sea. AISI 316 where there is salt and spray, 304 for interiors and the inland areas.
Light and it does not rust, so we choose it for balcony railings on tall buildings and wherever nobody will be maintaining the structure.
Immersion in molten zinc protects the inside of the profile as well. Powder coating in your RAL colour goes on top.
