Lock Bodies

-- Steady & Reliable Manufacturer --

Introduction

The lock body is the unsung hero of door security, the engineered heart concealed within the door that determines its strength and reliability. At Xiangshan Victor Hardware, we manufacture lock bodies that are the product of precision tooling, rigorous material selection, and exhaustive testing. Since 1996, we have evolved our designs to meet not just the demand for security, but also for convenience, fire safety, and architectural integration.

Our expertise covers mortise, cylindrical, and tubular lock bodies, each serving different security levels and door types. We utilize a combination of stainless steel, brass, and reinforced zinc alloy for internal components to ensure smooth operation over hundreds of thousands of cycles while resisting forced entry. For us, a lock body is not just a commodity; it's a critical safety component. Therefore, every batch undergoes functional cycle testing, torque testing on the deadbolt, and dimensional accuracy checks.

We serve a global clientele that includes lock set assemblers, door manufacturers, and large security projects. Our ability to provide keyed-alike, master-keyed, and grand master-keyed systems across thousands of locks makes us a trusted partner for apartment complexes, office buildings, and hotel chains where coordinated access control is paramount.

Application

Our lock bodies are specified for scenarios where security and reliability cannot be compromised:

Multi-Family Residential (Apartment Complexes): We supply large volumes of mortise lock bodies configured in master-keyed systems. This allows individual tenant keys to work only on their unit, master keys for maintenance staff, and a grand master key for property management, providing layered and efficient access control.
Commercial Office Suites & Banking: High-security mortise lock bodies with anti-drill and anti-pick features are essential for protecting sensitive data and assets. Panic exit devices with mortise locks ensure safe and immediate egress in emergencies while maintaining security from the outside.
Hospitality Industry: For hotel room doors, we provide lock bodies engineered for integration with electronic RFID or card lock systems. The mechanical override cylinder is precision-machined to ensure smooth operation for emergency master key access.
Educational & Government Facilities: Durability and vandal-resistance are key. We offer lock bodies with reinforced bolts and cases that can withstand significant abuse. Fire-rated lock bodies are mandatory for corridor doors and stairwells in such buildings.
Industrial & Warehouse Security: Heavy-duty tubular deadbolts with 1.5" throws and reinforced strike plates are used on perimeter gates, storage rooms, and warehouses to deter forced entry.

Advantage

Precision Key Control Systems: Our in-house key machine department allows us to offer complex, audit-trailed master key systems. We can generate and manage thousands of unique key codes, providing a complete keying schedule for large projects, which many suppliers outsource.
R&D for Modern Threats: We continuously update our lock designs to counter evolving break-in techniques like lock picking, bumping, and drilling. Our collaboration with security consultants ensures our products meet contemporary threat profiles.
Vertical Manufacturing Integration: From stamping the steel case to machining the pins and assembling the springs, we control every step. This allows for unmatched quality consistency and the agility to implement custom modifications (like special bolt faces or extra mounting holes) without long lead times.
Comprehensive Technical Support: We provide more than just products. We offer detailed installation templates, CAD drawings (DWG/DXF), and cross-sectional diagrams. Our engineers are available to consult on specifying the correct lock body for specific door materials (wood, metal, glass) and fire rating requirements.
Global Compliance Knowledge: Our products are designed to meet a matrix of international standards, including ANSI (North America), DIN (Europe), and AS (Australia). This expertise helps our distributors confidently sell into diverse markets without compliance concerns.

Payment & Shipping

We structure our terms to support both small trial orders and large project commitments.

Payment Terms: Standard terms are 30% T/T deposit, 70% balance against copy of Bill of Lading. For established distributors, we offer open account terms with credit limits after a successful trading history. Letter of Credit (L/C) is accepted for all orders.

Shipping & Lead Time: Production lead time for standard lock bodies is 30-35 days. For master-keyed systems involving thousands of key codes, please allow an additional 7-10 days for programming and testing. We palletize all lock body shipments for safe sea freight transport. Each pallet is shrink-wrapped and clearly labeled with PO and item details. Air freight is viable for samples and urgent small orders.

Packaging: Lock bodies are individually packed in anti-rust oil paper and then placed in partitioned cartons to prevent damage during transit. All hardware (screws, bolts, strike plates) is included and bagged together.

FAQ

Q: Can you supply lock bodies to work with our existing key system or a specific key blank?
A: Yes, this is a core service. Please send us a sample of your current key (or the key blank number, e.g., KW1, Y1, SC1) and, if applicable, a lock cylinder. We can pin our lock bodies to match your existing key bitting or source/compatible cylinders. For master key systems, we need your current master key chart or can help you design a new one.

Q: What is the difference between a Spring Latch and a Deadlatch?
A: A Spring Latch is a simple beveled bolt held retracted by a spring; it closes when the door strikes the frame. A Deadlatch has an additional "deadlocking plunger" that, when the door is closed, prevents the latch from being pushed back with a credit card or tool (a technique called "loiding"), offering significantly more security. We recommend deadlatches for all exterior doors.

Q: Are your fire-rated lock bodies clearly identifiable?
A: Absolutely. Our fire-rated lock bodies have the model number stamped on the case and are shipped with a manufacturer's data sheet that states the fire test rating (e.g., 45-minute, 90-minute). They often include fusible links or other heat-activated components that automatically retract the latch in a fire to allow safe egress.

Q: How do I specify the correct backset?
A: The backset is the distance from the edge of the door to the center of the cylinder hole. The most common are 2-3/8" (60mm) and 2-3/4" (70mm). You can measure this on an existing door. If it's a new door, 2-3/4" (70mm) is often recommended as it provides a longer deadbolt throw and is generally more secure. When in doubt, consult our technical sheet.

Q: What is your policy on providing spare parts?
A: We maintain an inventory of common spare parts such as springs, screws, and latches. These can be ordered separately. For out-of-production models, we can often fabricate parts if we have the original drawings, subject to a minimum order charge.
