Strength begins at the corners
One of Prowler Proof’s strongest points of difference is the way the frame is built. Diamond frames are welded before powder coating, helping create a cleaner finish and a stronger, more durable security screen.
Toughened Welded Corners
Unlike conventional mitred frames secured with screws or rivets, Prowler Proof frames are welded into a seamless structure before powder coating. The result is a stronger, cleaner-looking frame designed for lasting performance.
- Welded rather than assembled with screws or rivets.
- Joined into one continuous frame structure.
- Powder coated after welding for a seamless finish.
- Fewer potential weak points and corrosion risks.
- Cleaner appearance across hinged and sliding door openings.
