Why Choose Boomster?

• Solid Forged Alloy Construction for Maximum Structural Integrity: Unlike zinc or brass die-cast handles prone to internal porosity, shearing, and fatigue failure, our levers are produced via hot/closed-die forging in brass, stainless steel, or aluminum. This process guarantees dense grain flow alignment, superior impact resistance, and high torsional strength required for heavy-duty architectural and commercial hardware.
• Precision CNC Machined Spindle Hubs & Spring Retainers: Featuring multi-axis CNC machining on internal spindle bores, spring retaining slots, and set-screw threads. Tight dimensional tolerances ±0.005mm guarantee seamless integration with mortise locks, tubular latches, and rose mechanisms without handle sag or lateral play.
• Advanced Architectural Surface Finishes (PVD, Electroplating): Solid forged substrates provide a flawless surface foundation for architectural finishing. We offer PVD (Physical Vapor Deposition), brushed brass, antique bronze, electroplating, and powder coating, passing hour Salt Spray Tests for long-term corrosion resistance.
• Guaranteed 3-Year Quality Report Traceability: Every shipped batch includes a complete quality documentation package—including Material Composition Certificates, Salt Spray Test reports, and CMM dimensional check sheets. Boomster archives all Inspection Reports (IR) and raw material heat records for at least 3 years from the shipping date.
• Overseas Shipment Consolidation & Turnkey Logistics: To help global hardware brand owners streamline supply chain logistics and lower landed costs, Boomster offers overseas shipment consolidation. We enable clients to combine forged door levers, escutcheon plates, and lock hardware into single, cost-effective container shipments.
