Anti-jimmy hinge bolts
Anti-jimmy hinge bolts are security features designed to prevent forced entry by reinforcing door hinges. Installed on outward-opening doors, these steel bolts keep the door securely in place even if the hinges are removed. Ideal for commercial and residential properties, they enhance overall door security.
Anti-jimmy lips
Anti-jimmy lips are protective door-edge reinforcements that prevent intruders from prying a security door open with crowbars or tools. Commonly found on security doors, these metal lips act as a physical barrier, increasing resistance to forced entry.
Aperture
In door and window manufacturing, an aperture refers to an opening in a door or wall, typically designed for glazing panels, letterboxes, or ventilation grilles. Custom apertures allow for better functionality, visibility, and design flexibility in both residential and commercial security doors.
Closer panel
A closer panel is an additional panel installed alongside a door to provide better closure, structural support, or aesthetic uniformity. It is commonly used in wider doorways or partitioned areas to enhance security and insulation.
Crash Bar
A crash bar, also known as a panic bar, is a horizontal push-bar mechanism installed on emergency exit doors. Designed for quick and easy egress, it allows users to exit a building swiftly by applying pressure, making it a crucial safety feature in commercial and public buildings.
Deadbolts
Deadbolts are high-security locking mechanisms that require a key or thumb turn to operate. Unlike spring locks, they offer enhanced resistance to forced entry by extending a solid metal bolt into the door frame, making them a popular choice.
Door Slab
A door slab is the main, solid part of a door without hinges, hardware, or a frame. It serves as the core structure, allowing for customization with different materials, finishes, and additional security features like reinforced cores or fire-rated designs.
Expandable frame
An expandable frame is a flexible door frame system that adjusts to fit varying wall thicknesses, simplifying installation and ensuring a secure fit. Ideal for retrofit projects and modular construction, these frames provide durability and adaptability.
Fiberglass
A durable, lightweight composite material made from fine glass fibers embedded in a resin matrix. It provides strength, insulation, and resistance to warping, rotting, and moisture damage, making it an excellent choice for long-lasting, low-maintenance doors.
Galvanized steel
Galvanized steel doors and frames are coated with a protective zinc layer to prevent rust and corrosion. Ideal for high-security and industrial applications, galvanized steel doors provide exceptional strength, weather resistance, and longevity.
Key cylinder
A key cylinder is the core component of a lock that houses the pins and tumbler mechanism. Available in various security grades, key cylinders determine how a lock functions, whether through a single-key system, master keying, or advanced security options like anti-pick technology.
Lever handles
Lever handles are door handles designed for ease of use, featuring a horizontal lever that operates the latch mechanism. Common in both residential and commercial settings, they provide better accessibility compared to traditional doorknobs, making them an excellent choice for ADA-compliant installations.
Lift off hinges
Lift-off hinges allow doors to be easily removed without unscrewing the hinges, making them ideal for areas requiring frequent access or maintenance. Commonly used in hospitals, commercial kitchens, and industrial settings, they enhance convenience and efficiency.
Mineral wool
Mineral wool is a fire-resistant and soundproof insulation material commonly used in fire-rated doors. It enhances thermal efficiency, reduces noise transmission, and improves fire safety, making it a key component in commercial and high-security doors.
Multi-point locking system
A multi-point locking system secures a door at multiple points along the frame using a single locking mechanism. Found in high-security residential and commercial doors, these systems offer superior protection against forced entry, improving security and energy efficiency.
Panic bolt bar
A panic bolt bar, similar to a crash bar, is a horizontal exit device used in emergency doors. It allows for fast, keyless egress by activating a latching mechanism when pushed, ensuring safety compliance in public buildings, schools, and commercial spaces.
Reinforced Friction Stay Panel
A reinforced friction stay panel provides additional structural support to doors and windows, allowing controlled opening while preventing accidental slamming. Commonly used in security and fire-rated doors, these panels improve durability and operational stability.
