The Australian Trellis Door CompanySecurity Doors

The Australian Trellis Door Company™ Pty Ltd (“A.T.D.C.”) commenced operations in 1985 when it introduced the expanding trellis security door concept to Australia & New Zealand. Since that time A.T.D.C. has remained the market leader in this field, having developed arguably the world’s most extensive and diverse range of expanding trellis security doors suitable for securing most residential, commercial and industrial applications. Our engineers have pioneered world first innovative security features such as the unique triple point slam-lock and the heavy duty track locking bottom track facility. Furthermore the S02-1™ / S05-1™ ultra deluxe model doors are the only fully framed square steel tubular trellis doors currently available on the Australian market. In recognition of our product quality, our customer service and our company’s technological advancements, we have been invited to participate on many prestigious projects such as the Australian National Maritime Museum, The Bovis Lend Lease / Telstra national contract, the Woolworths Plus Petrol national contract and the Dick Smith Electronics national contract. A sample customer list appears on clients for easy reference. In addition, our products are now sold world-wide including the USA, North America, UK, Europe & New Zealand. Whilst continually seeking to further develop our trellis security door range as new technologies come to hand, our engineers have also focused on developing other quality security products in an effort to provide the customer with what is now the most diverse range of barrier security systems on the market. All products are manufactured and assembled in our factory in St Peters, Sydney. They include steel security doors and window grilles, key lockable removable window bars, driveway gates and aluminium roller shutters and folding closures.
