SR3 Doors (C5)

PS3 Stainless Steel Security Doorsets

Built on over 30 years of “fit and forget” manufacturing expertise, the PS3 has been engineered to deliver enhanced protection while maintaining exceptional durability and low maintenance. When we entered the steel security door market, our aim was not simply to produce another steel door, but to create a long-lasting security solution that avoids the corrosion issues often associated with conventional steel doors.

To achieve this, our entire product range is tested and certified in stainless steel, using 304 or 316 grade materials. Each doorset is mounted on full-length stainless steel continuous hinges and fitted with stainless steel locking furniture, ensuring outstanding strength, reliability, and resistance to rust. The result is a high-performance security doorset designed to be as close to maintenance-free as possible.

Certified Security Performance

The PS3 doorset is certified to LPS 1175 Issue 8, achieving:

• PS3 Security Rated SR3 (C5)
• Listed on Red Book Live

This certification verifies the doorset’s ability to withstand more determined attacks using a wider range of tools, making it suitable for higher-risk environments such as commercial premises, infrastructure sites, public buildings, and critical facilities.
