Mastcraft historia

In the beginning there were work gloves, a smith hammer and a forge

MastCraft Oy was originally founded as Keskipohjanmaan Konekorjaamo in 1948.Thus, the company has nearly 70 years of experience in metal building.It was founded in the growth centre of Ylivieska in northern Ostrobothnia to respond to the need for metal products in the developing city.As a new family took over the ownership of MastCraft in the 1970s, its core competence became the production and installation of steel structures.Timo Pälli and Olli Seppälä are third-generation entrepreneurs in the company and continue MastCraft's tradition as an expert in steel and network building.Since the dawn of the company, the smith hammer has been joined by modern metal technology to further strengthen our traditional skills in metal crafting.MastCraft Oy is the third oldest functioning company in Ylivieska.

Olli is a thinker with a strong backbone, efficient, enthusiastic, determined, an ordinary Finnish and Ylivieskan man who appreciates a job well done in all its forms.And especially when it’s done with great expertise.Olli also appreciates an easygoing atmosphere and a twinkle in the eye.
