Ladder string, loop tape and lift tape for outdoor venetian blinds are uniquely exposed to wear and tear. Not only UV radiation and heat but also frost and moisture affect all components of external sun protection systems.

Julius Koch technical textiles for outdoor venetian blinds were developed precisely to withstand these challenges and guarantee the necessary durability to maximize the lifespan of your sun protection systems. This is proven by our quality testing procedures with regard to breaking strength, elongation and colour fastness .
