Build stair with steps of solid single blocks of porphyry and create a stunning effect!

The more expensive laying costs and cost of the product discourage designers and the use of this product. But a close analysis shows that, if one considers the great appearance and their almost unlimited durability the solid steps are a competitive option.

For exteriors, the natural and flamed surfaces represent a tread surface which is one of the most non slip and safe.

The working of the sides is particularly important, as it determines the whole appearance of the flight of steps. So it is necessary to choose the most suitable finish carefully for the architectural setting and the other materials present.

The thickness varies from 6 to 20 cm. There is no difficulty in supplying, on request, steps with fan or curved or with other special shapes.

Build stair with solid steps: the treads

The horizontal part (the tread) of solid steps may be:

Build stair with solid steps: the visible sides

You can build stair with the following effects for the visible sides of the steps:

  • Natural surface: the natural surface must be regular with 0.5 cm tolerances: the visible sides stanclardised at least 5 cm, the others sawn. The parts not standardised may not be more than 3 cm more than the stanclardised side.
  • Flamed: flamed steps are usually obtained from grinding compact blocks with diamond disks. They will therefore have the uniform thickness required.
  • Sand textured: the ground surface is sand textured.

Build stair with solid steps: the visible sides

You can build stair with the following effects for the visible sides of the steps:

Split: this results from an ashlar finish using mallets and heavy hewing tools. The side has a continuous bulge up to 3 cm and you get a very rustic effect if you build stair with it.

Coarse points: from the split surface, by hand with mallets and large chisels of steel the bulges are altered and “points” are highlighted every 2/3 cm.

 Fine points: the same process as above, but with finer chiselling.

Bush hammer (bocciardata): this effect may be produced by hand using the special tool, after having finished the above processes. However, nowadays it is carried out by machines which work on the disk ground surface. The edges, which can’t be treated by machine are left sawn, or worked with a chisel or polished. The edges should never be left sharp.

Ground: the surface of the side is left after disk grinding, the edges are chamfered, at least enough to take off the sharpness.

Flamed: the ground surface is flame textured. The edges must be chamfered to at least 5 mm, but it is even better if they are rounded and flamed. The surface of the side looks similar to the natural surface and the whole step has a continuity between its horizontal and vertical sides which is particularly pleasant.

Sand textured: the side is sand textured in a uniform way, the edges are chamfered.
