Ultra-Narrow Series

Comprehensive architectural solutions encompassing sliding doors, swing doors, and French doors engineered on a unified narrow profile system by Meric Window Systems Co., Ltd.

System Architecture

Unified Narrow Sightlines Across Sliding and Swing Configurations

In conventional architectural projects, purchasing sliding doors and swing doors from separate manufacturers often results in mismatched frame profiles and inconsistent sightlines. The Ultra-Narrow Series from Meric Window Systems Co., Ltd. solves this problem by using synchronized profile engineering—enabling sliding and swinging leaves within the same room to maintain identical visual profiles.

Single Visual Sightline

The Perfect push-pull and Perfect flat-open lines, alongside the 4010, 4016, 4007, and 40 Golden Triangle families, share identical profile geometries for a uniform appearance.

Concealed & Surface Mounting

Frames can be embedded into the wall reveal before plastering for a frameless effect, or surface-mounted directly onto finished walls during renovation.

Engineered Sight Deductions

Pre-calculated formulas ensure precise glass cutting: opening height minus 25 mm gives sight height; opening width minus 50 mm gives sight width.

Porcelain Electrophoretic Finish

Available in Porcelain Black, Brushed Bronze, and Brushed Silver finishes, engineered over 6063-T5 aluminium for maximum scratch and corrosion resistance.

Product Classification

Three Door Configurations, One Profile Line

Factory Direct Quality Assurance

Every project manufactured by Meric Window Systems Co., Ltd. follows an audited 6-step export fulfillment protocol designed for international trade peace of mind.

1. Shop Drawing Verification

Elevation CAD drawings, section details, and structural deductions are issued for formal approval prior to extrusion cutting.

2. Precision CNC Fabrication

Extrusions are processed on high-precision CNC machining centers for exact lock mortising and corner crimping accuracy.

3. Pre-Shipment Assembly

100% of door sashes are test-fitted into frames to verify roller smoothness, lock alignment, and gasket compression.

4. Sea-Worthy Export Crating

Finished units receive surface protection film, corner buffers, and are packed into solid reinforced wooden crates for container transit.

Frequently Asked Questions

Technical & Procurement FAQ

Key information for architects, developers, and trade importers specifying the Ultra-Narrow Series.

Yes. Meric Window Systems Co., Ltd. specifically engineered the Ultra-Narrow Series so that push-pull sliding doors and flat-open swing doors utilize matching extrusion profiles. This allows adjacent sliding and hinged doors to share identical visible sightlines across a single elevation.

Under standard installation guidelines, visible sight height equals structural opening height minus 25 mm, and visible sight width equals structural opening width minus 50 mm. Our technical team verifies these dimensions on the shop drawings before production.

The Ultra-Narrow Series is primarily engineered around single glazing for interior partitions, luxury villa interior doors, and covered loggias. For exterior building envelopes requiring thermal breaks and double glazing, we recommend our FW142 Curtain Wall Window or JW157 Panoramic Sliding Door systems.

Concealed mounting buries the outer frame profile into the wall reveal before wall plastering is applied, creating a frameless look where wall finishes flush against the glass line. Surface mounting secures the outer frame onto finished wall reveals, ideal for renovation projects.

Our standard architectural finishes include Porcelain Black, Brushed Bronze, and Brushed Silver produced via premium porcelain electrophoretic technology. Custom RAL powder coating can also be accommodated for qualified commercial volumes.
