Our factory door designs aim for absolute perfection

The value of our door designs lies in their extraordinary adaptability. Your factory’s unique qualities (which include the number of staff, traffic levels, location and weather, safety factors, and the purpose of the doorway) place equally unique demands on the personal access doors you need.

Our heavy-duty Sentry™ factory door designs boast extreme durability and come in wind and cyclone-rated designs. We offer hard-wearing finishes, including Colorbond®, galvanised and Zincanneal® steel, and corrosion-resistant MetaPrep™. And if you don’t find the perfect factory door? We’ll design and manufacture a one-off custom to your exact specifications.

The industry-leading versatility of Sentry™ factory doors

Our world-class designs are suitable for all factories, regardless of size, foot traffic levels or regulatory requirements.
