Why use the LPS 1175 Issue 7 SR3 Steel Security Doors?

Choosing LPS1175 Level 3 Security Rated Steel Doors from Security Direct is a strategic investment in superior protection for your property. Our SR3 doors are designed to meet the highest standards set by the Loss Prevention Certification Board (LPCB), achieving certification to LPS 1175 SR3. This level of security ensures that these doors provide formidable resistance against forced entry, making them ideal for high-risk areas such as retail outlets, cash rooms, warehouses, and utility substations.

The construction of our LPS1175 Level 3 Security Rated Steel Doors is engineered for maximum security and durability. Each door leaf is 51mm thick, crafted from 1.5mm galvanized steel on both the attack and inner faces, with a composite structure designed to withstand significant impact. The door leaves also feature an astragal lip on the closing edge for added security, and the entire structure weighs approximately 80kg per square meter. The welded frames are reinforced at critical points, including hinges and lock keeps, to enhance their robustness against tampering.

Customisation and flexibility are key features of our SR3 Steel Security doors. These doors can be outfitted with a range of high-security hardware options, including Hooply Cefiro multipoint locks, Mico Tindall push pads, and lever handles. Heavy-duty tower bolts on the passive leaf further enhance security, and keys and cylinders can be registered to prevent unauthorided copying. Additionally, these doors are available with louvre panels, subject to hardware compatibility, offering ventilation options without compromising security.
