Sliding Window Flush Lock HC-FM-200: Builder & Wholesale Sourcing Guide

Executive Summary: Sliding Window Flush Lock Selection

  • Flush Means Secured: A sliding window flush lock sits into the frame line, removes the snag risk of a surface latch and keeps the sash sealed against weather and forced entry.
  • Finish Decides Approval: Matte black, silver and colour zinc options cover most US and EU schedules, while 72 to 96+ hour salt spray data supports coastal projects.
  • Distributor Ready: Minimum order quantity starts at 500 pieces, buffer inventory supports 7 to 14 day dispatch and OEM/ODM runs include private label packaging.

1. Why Specifiers Choose a Sliding Window Flush Lock

Sliding window flush lock hardware solves two problems at the same time: it secures the sash and it keeps the window line clean. Specifically, a flush body sits inside the frame rather than on top of it, which eliminates the snag point that surface latches create on curtains, blinds and cleaning equipment.

Commercial and multi-family projects increasingly specify flush hardware for that reason. Furthermore, a concealed mechanism is harder to defeat with leverage than an exposed latch, and it collects less dirt on a building facade. Consequently, the component is now standard on many aluminium sliding window systems. Related hardware families are listed in the Huachuang product catalogue.

2. HC-FM-200 Assembly Details and Finish Options

The HC-FM-200 combines a zinc alloy body with a slim faceplate and a keyed cylinder, which keeps the lock unobtrusive when the window is closed. Specifically, the mechanism is designed for aluminium sliding window profiles with a milled edge recess, and the cylinder can be supplied keyed alike across a project. Technical details are published on the HC-FM-200 product page.

Finish choice usually decides approval on facade-critical work. Practically, matte black suits contemporary aluminium joinery, silver matches mill-finish frames and colour zinc is used where a warmer tone is required. Because the same plating line supports our door lock and roller families, colours remain consistent when a project mixes window and door hardware from us.

4. Corrosion and Cycle Evidence for Coastal Projects

Coastal and high-humidity openings punish thin plating within a single season, so evidence matters more than appearance. Concretely, our finishes are validated for 72 to 96+ hours of neutral salt spray under ASTM B117, and assemblies are fatigue-tested beyond 100,000 continuous cycles. Reports are filed in the certified test report library.

Coatings use heavy-metal-free trivalent chromium chemistry supported by SGS RoHS documentation, and structural benchmark language follows published FGIA testing guidance for US fenestration work.

5. Distributor Supply, OEM/ODM and Lead Times

Huachuang Hardware manufactures in Zhongshan, Guangdong as a source factory rather than a trading company. Specifically, we operate more than 1,000 proprietary die-casting and stamping molds, LT-40 CNC lathes, progressive die stamping and automated pneumatic assembly, all governed by an ISO 9001 quality system. Production depth, including tooling and machining, is documented on the factory capabilities and tour page.

For OEM and ODM programmes we handle custom faceplate lengths, bespoke finishes, private label cartons and customer part numbers. Additionally, minimum order quantity starts at 500 pieces per SKU, stock configurations dispatch in 7 to 14 days from buffer inventory, and mixed container loading with door locks or rollers keeps freight per unit low.

6. Frequently Asked Questions

Q1: Which window profiles does the HC-FM-200 suit?

It is designed for aluminium sliding window profiles with a milled edge recess. Send your profile section or a photo of the existing lock and we will confirm the compatible body and faceplate length.

Q2: Can finishes be matched across window and door hardware?

Yes. Matte black, silver and colour zinc finishes are produced on the same plating line used for our door locks and rollers, so a mixed hardware schedule keeps a consistent appearance.

Q3: What is the minimum order for private label supply?

Stock finishes start at 500 pieces per SKU. Custom finish or printed cartons typically start at 1,000 pieces with artwork approval before production.

Q4: How do I request a quotation?

Email sales@zshuachuang.com with the profile details, finish, keying requirement and quantity. Our team replies with a drawing, OEM or ODM options and lead times.
