Sourcing sash locks for windows that meet North American safety standards, withstand environmental exposure, and arrive on time is a common challenge for import managers and brand owners. Shijiazhuang TJJ TRADE CO., LTD. (TJJ) offers a direct line to a Chinese foundry with over 20 years of experience in metal window hardware. Our sash locks for windows are manufactured under ISO 9001 quality systems, available in OEM/ODM designs, and shipped with lead times as short as 20 days. This page provides the technical data, compliance info, and customization options you need to evaluate TJJ as your supply partner.
Common Sourcing Pain Points & How TJJ Solves Them
Pain point 1: Inconsistent quality and dimensional accuracy
Many importers report that cheap sash locks from unverified suppliers fail during US-style lifecycle tests or corrode quickly in coastal climates. TJJ operates a dedicated casting facility with in-house mold design, CNC machining, and statistical process control. Each batch of sash locks for windows is checked for latch alignment, spring tension, and finish adhesion. Our warranty rate has remained below 0.3% over the last three years.
Pain point 2: Long lead times and communication gaps
Our factory is located in Shijiazhuang, Hebei Province – a major hardware manufacturing hub. Average production time for standard orders of 5,000–20,000 units is 25 days. OEM/ODM prototypes can be turned around in 10 business days. Account managers respond in English within 4 hours during working days.
Pain point 3: Hidden costs in compliance and logistics
We deliver FOB Tianjin or CIF to major US ports. All sash locks for windows are tested to meet ANSI/BHMA A156.20 (American National Standard for Cabinet Hardware) and ASTM B117 salt spray resistance (minimum 120 hours for zinc alloy). Certificates are provided with each shipment.
