Asec
ASEC is a trade-focused security hardware brand built around the “everyday kit” locksmiths and installers reach for, with a big emphasis on breadth, availability, and value rather than boutique-only spec pieces. The brand was established in 2003 and was created specifically to support independent retailers and security professionals with products that “would never become available through the large multiple retailers.”
Where ASEC gets especially interesting (and why it tends to become a “default stock brand”) is the scale of the range:
-
ASEC positions itself as having a portfolio of 2,000+ individual products, described as one of the largest ranges under a single security brand name in the industry.
-
Coverage is intentionally broad across the core trade categories: Access Control, Architectural Hardware, Key Cutting, Locking Products, UPVC, Tools & Accessories.
ASEC is exclusive to Aldridge Security (whom we distribute) in the UK trade ecosystem (Aldridge explicitly calls itself the exclusive distributor of ASEC Security Products worldwide). That exclusivity is a big part of the brand’s identity: it keeps the range aimed at the trade channel rather than getting diluted into mass retail.
Bullet & Shutter Locks
Secure your commercial premises with our robust range of bullet and shutter locks, specifically designed for industrial steel doors and roller shutters. This specialist security collection includes heavy-duty bullet locks, which feature removable cylindrical pins that fit into side housings to physically block the guide rails, alongside central shutter locks equipped with double-throw bolts that extend securely into the side guides. Ideal for shopfronts, warehouses, and industrial units, these high-security locking solutions provide reliable protection against forced entry. View all Bullet & Shutter Locks products
