Welcome to Trellis Gates Durban – Coastal Trellis:

Coastal Trellis was formed in 2010 through the merger of Ultrador and Robodoor(kzn), both of which had manufactured security gates (Robodoor since 1995) The factory is situated in Pinetown where we still manufacture affordable yet durable window and door barriers. Although we market and install our products throughout the Durban region, we also make use of distributors in other areas.We are looking to expand our distribution network and interested parties are invited to contact us in this regard. We have been manufacturing security barriers for almost 20years and are continuously doing research and product development in order to supply our clients with the right product at the right price.

What Trellis Gates Durban has to Offer:

In 2010 Coastal Trellis in conjunction with a major aluminium supplier, made the change from steel to aluminium which afforded us the opportunity to make changes/improvements to the products, some of which are:

High Strength structural grade aluminium alloy.
The extrusion process allowed Coastal Trellis to design the gate for smoother and quieter slide movement and improved strength.
The rollers are manufactured from a high quality grade plastic designed to improve durability and reduce noise levels.
A plastic handle was also incorporated to enhance the aesthetics of the finished product.

The standard colours available are Bronze, White, Charcoal, New Silver and Sand, but other colours are available on request.
