KiNG TRELLiS started out as an engineering company but soon realised the need for a more robust door after a robbery at our premises had intruders compromise a "competitors barrier". This lead us to develop the KiNG TRELLiS RETRACTABLE BARRIER range, which we have been promoting since 1999. With our extensive knowledge and grounding in the Mechanical Engineering and Tool & Die Making fields, we are constantly striving to improve the quality of our products. Our dedicated team delivers swift service, resolves after-sales queries and repairs in the event of a forced entry. Your home is you castle, so choose KiNG TRELLis to protect your kingdom.
