How We Began

The company entered the sliding door manufacturing business in 1996, to cater to the growing market for the popular door system. What began as a supplier with a stock of only 50 cavity doors now serves thousands of clients.

For two decades, we have produced door systems that are backed by research and manufactured to the highest standards in the trade. During that time, we have expanded our company and facilities to serve more clients and to meet the growing demand.

Why Sliding Doors

Interior sliding doors are popular because of their aesthetic appeal and function. Light and versatile, they provide a sleek look to both homes and workplaces. Bi-fold door systems are ideal for high-end properties. The symmetrical design gives a neat and modern appearance that our clients love.

In addition to being a stylish fixture, sliding doors are easy to open and close, can cover various sizes of openings and come in a variety of designs. Property owners who want a rustic and cosy look may opt for wooden doors with glass centres, while others may prefer a solid-coloured version for a more professional look.
