Custom made

BPS manufactures custom-made stairs. The cus-

tomer is completely free in his choice of riser and

tread, width of the steps,...

Straight stairs as well as winding staircases are

possible. We use a large number of standard

forms but are also able to make special formwork

for specific staircases.

If desired, we can also manufacture the landings

and integrate them in the staircase. In addition,

we provide different solutions for the bottom and

top connection (see drawings). Our state-of-the-

art concrete plant, our own laboratory and our

internal inspection system guarantee impeccable

quality. We deliver high-quality products, both

where appearance and concrete strength are

concerned.

Our efficient and customer-friendly approach ena-

bles us to deliver in accordance with the agreed

terms and at competitive prices. This has earned

us a growing number of loyal customers, at buil-

ding sites in Belgium and abroad (England,

France and Netherlands).

We are always prepared to answer your questions

and help you find the best solution, both from an

economic and from a technical point of view.

The advantages of prefabricated stairs are nume-

rous: high quality, no loss of time at the building

site, no forms at the building site, a competitive

price agreed upon in advance, ...

The stairs of BPS meet the applicable Belgian fire

prevention standards, which is an additional asset

these days, as the appointment of a safety coor-

dinator has become obligatory. We offer stairs

with or without anti-skid nosing, with or without

closed string, in grey concrete as well as in archi-

tectural concrete.
