About 300 companies are participating in the 2013 spring edition of Bulgaria's largest construction expo "Stroyko 2000".

Stroyko is opening formally for the 40th time on Wednesday, and will last until April 2, taking place in the National Palace of Culture in Sofia.

Stroyko has been held for the last 20 years every spring (March) and fall (October).

The week-long event will display products of companies from the sector, covering the whole spectrum of construction services - equipment, machinery, tools and supplies, building chemicals, concrete, ceramics, coatings and finishes, energy-saving technology, furniture and accessories.

Decorative elements - railings, grilles, shutters, curtain walls, winter gardens, as well as locking and heating systems will be the highlight in the thirty-ninth edition of the expo.

Despite the economic stagnation, leading to a smaller number of companies participating, customers will still be able to enjoy the traditional 10% discount on everything.
