Stainless Steel Glass Door Lock

Heavy-Duty Stainless Steel Frameless Glass Door Lock for Commercial & Architectural Applications 

Engineered for 8mm to 12mm tempered frameless glass doors, this stainless steel glass door lock provides secure mechanical latching and deadbolt operation for high-traffic commercial interiors. Precision CNC-machined from solid bar stock and investment-cast stainless steel, this lock eliminates structural looseness and delivers long-term corrosion resistance without relying on surface plating.

Selecting the correct lock configuration depends on door operation frequency, environmental exposure, and security requirements.

Material Grade Selection
• AISI 304 Stainless Steel: Standard specification for indoor commercial offices, retail partitions, and temperature-controlled environments. Offers dependable resistance against oxidation and standard cleaning agents.
• AISI 316 Stainless Steel: Recommended for coastal installations, high-humidity natatoriums, or exterior-facing glass entries. Contains molybdenum for enhanced resistance to chloride pitting and industrial fallout.

Cylinder & Locking Configuration
• Double Cylinder (Key/Key): Secures entry from both sides; required where strict access control is mandated.
• Single Cylinder with Thumbturn (Key/Turn): Standard for interior offices and conference rooms, allowing rapid egress from the interior without a key.
• Latch-Only (No Cylinder): Used with magnetic hold systems or push-pull handles where locking security is not required.

This lock is dimensioned for standard glass preparation cutouts, minimizing installation labor and preventing on-site modification errors.

Office Partitions: Integrates directly with 10mm and 12mm glass panels in aluminum or frameless office systems.

Retail Storefronts: Withstands heavy daily cycle rates in shopping malls and street-level boutiques.

Hospitality Entrances: Provides clean architectural lines matching stainless steel pull handles and floor springs.

Reliable hardware performance starts with raw material control and dimensional repeatability.

Material Traceability: Spectrometer material analysis reports are generated for every production heat to verify chemical composition (18Cr-8Ni for 304; 16Cr-10Ni-2Mo for 316).

Dimensional Accuracy: CNC machining centers maintain strict positional tolerances within +/- 0.05 mm, ensuring gasket alignment and preventing uneven clamping pressure on tempered glass.

Torque & Clamping Tests: Each batch undergoes torque verification on clamping bolts to ensure secure grip on glass without exceeding safe stress thresholds that cause micro-cracks.

Surface Finishing: Automated mechanical polishing followed by ultrasonic cleaning removes all machining oils, passivation residue, and particulate contaminants before packaging.

When qualifying suppliers for architectural glass hardware, verify the following baseline metrics:

In-House Testing Capability: Does the supplier maintain salt spray testing chambers, spring dynamometers, and optical profile projectors on-site?

Batch Consistency: Can the factory provide Mill Test Certificates (MTC) for raw stainless steel bars and castings?

Packaging Standards: Are components individually wrapped in foam and anti-corrosion polybags to prevent transit scratching on polished surfaces?

OEM Customization Support: Capability to laser-engrave client logos on lock bodies or supply non-standard Euro cylinder lengths for thicker acoustic glass assemblies.

Minimum Order Quantity (MOQ): 50 sets per finish/model for standard catalog items; 200 sets for custom laser branding or specialized cylinder keying.

Lead Time: 15 to 25 business days for standard production runs; 35 days for custom PVD color variants.

Sample Policy: Working samples available for evaluation; freight collect via DHL/FedEx.

Standard Packaging: 1 set per inner white box, 20 sets per master export carton reinforced with corner protectors.
