About us


STS d.o.o. is located in Banja Luka, in the northern part of Bosnia and Herzegovina and we operate within the company Maxmara Ltd. one of the largest manufacturers of windows, doors and facades in the country.

The company was founded with the idea to begin production of aluminum ladders with Italian partner, STP from Milan. STS produces three lines of ladders in several models; Professional ladders for daily intensive and professional use; Hobby ladders intended for individual and occasional use and household ladders intended for domestic use.

All our products are made of high class aluminum and are in accordance with European standard EN 131 and for most models we have GS TUV certificate. Today our products are sold in most European countries and beyond, and we issue EUR 1 (statement of origin) for those products.
