The Rockdoor composite doors boast of 60% greater density core and the 25mm sintered steel hooks reinforce the outer room.

The inner frame is impermeable to moisture while its aluminium reinforcement makes it super strong. At Rockdoor, each door is customised according to measure. 

Key Features of Rockdoor

The best in the industry, Rockdoor prices/costs are affordable and worth the investment.

The 3-star lock cylinders have secured the highest rating; the SS312 Sold Secure Diamond status, the ultimate in burglar-proof locks. Rockford as a brand values quality and does not compromise in any way. 

What makes our doors stand out is the way that they are designed and produced. Rockdoor installers ensure that each door is reinforced, and can withstand almost anything. The main feature is definitely the Steel Security Mesh which is impossible to cut through but at the same time will not change the look of the door you require. The inner aluminium frame protects the door from temperature fluctuations, enables the locking mechanisms and hinges to be fixed, and elevates the door’s performance. 

Each door is Secured by Design, and the steel hooks at multiple points ensure that the locks hook on to the entire length of the outer frame, making it impossible for any forced entry. The steel hooks also secure the door sash and hold it in place with a deadbolt that doubles the door’s strength.

Another key feature of our doors is the unseen gearbox that plays a vital role in making sure the locks function smoothly.
