STS was established in 2005 in Banjaluka in cooperation with the Italian partner STP. The main idea was to produce high quality aluminum ladders and scaffoldings for professional use. STP Company, who is also co-owner of STS have over 30 year long experience in this field and is the leader in the construction ladders in Italy.
All our products are tested by Polytechnic Institute in Milan according to the European norm EN 131.
Our products are safe and simple to use (fast folding and unfolding), and lightweight which allows easy transport. Ladders and scaffoldings are made of high quality aluminum alloy - duralumin. Profile width differ depending on the type and size of the ladder and it can be from 67 to 100mm. Horizontal profiles – non slip rungs are fixed on to the frame with square reverting and non-slip stoppers. End caps prevent slipping and damage of the base.
We have different range of ladders: straight, extended, telescopic, fruit picking and double ladders.
