Frequently Asked Questions

Meric Window Systems Co., Ltd. is a project-focused manufacturer specializing in customized architectural envelopes. For standard mixed export shipments, our standard starting threshold is one 20ft container. However, for specialized commercial projects, custom villa developments, or mock-up verification prior to bulk production, single sample units and architectural profile sections can be ordered upon technical review.

Yes. Every window and door unit is built strictly to order. Our technical department reviews your elevation plans, architectural CAD files, BIM models, and window schedules. Before fabrication commences, we generate complete shop drawings detailing profile structural depth, drainage channels, glazing thickness, and hardware installation points for formal engineering sign-off.

We provide full OEM and ODM manufacturing capabilities. We can engrave custom branding, generate tailored protective film wraps, and construct specific export crating. If your project demands matching an existing architectural profile or developing a new thermal break extrusion die, our tooling engineers analyze the cross-section geometry to provide precise feasibility assessments and die cost estimates.

All profiles manufactured by Meric Window Systems Co., Ltd. are extruded from high-purity 6063-T5 aluminium alloy, delivering superior mechanical strength and structural stability. Structural wall thicknesses range from 2.0 mm as baseline standard up to 3.0 mm for heavy-duty sliding interlocks, curtain wall mullions, and high-wind zone applications.

Sightline width represents the visible aluminium profile width observed from the interior aspect. We base all published figures on precise production extrusion measurements. Our minimal sliding door interlocks feature visible face widths as narrow as 20 mm to 22 mm, while casement and tilt-turn systems range between 30 mm and 47 mm to accommodate multi-point locking gear and perimeter EPDM weather seals.

For ultra-narrow manual sliding systems, individual sashes are typically designed up to 1,200 mm in width and 2,700 mm in height to ensure smooth manual operation. For oversized architectural openings, our Lift & Slide systems allow single panels reaching up to 6,000 mm in width and sash weights exceeding 1,000 kg, supported by heavy-duty stainless steel carriages and precision roller tracks.

Our thermal break systems utilize high-grade PA66 polyamide insulating strips reinforced with 25% glass fiber. This mechanical barrier prevents thermal conduction across the aluminium frame, significantly reducing overall U-values, eliminating interior frame condensation, and satisfying energy codes for both freezing northern regions and extreme tropical heat zones.

We supply a broad range of certified double and triple Insulated Glass Units (IGU), including toughened safety glass, laminated security glass, Low-E solar control glass, tinted float glass, and acoustic PVB interlayers. Standard build-ups range from 5mm+12A+5mm to triple 6mm+16A+6mm+16A+6mm units with argon gas fill and warm-edge spacer bars.

Yes. By adjusting profile thermal break width, glass thickness, gas cavity dimensions, and triple-gasket perimeter seals, Meric Window Systems Co., Ltd. configures units to fulfill project-specific thermal transmittance (U-value) targets down to 1.1 W/m²K and sound transmission class (STC) ratings exceeding 42 dB.

For installations near salt air, coastal shorelines, or areas of aggressive atmospheric corrosion, we apply high-performance PVDF fluorocarbon coatings or Qualicoat-certified architectural powder coatings. Hardware components are upgraded to 304 or marine-grade 316 stainless steel to eliminate surface oxidation and galvanic corrosion over extended service lifespans.

Structural mullion moments of inertia (Ix/Iy values) are calculated by our engineering team according to local wind load pressure figures provided for your site. Additional steel internal profile stiffeners and heavy-duty anchor brackets are integrated for high-rise commercial structures and coastal hurricane zones.

Standard fabrication takes 20 to 35 business days from the formal confirmation of technical shop drawings and deposit receipt. Orders requiring specialized custom glass build-ups, non-standard RAL color finishes, or specialized hardware imported from Europe may require adjusted lead times, which are clearly noted in the final proforma documentation.

Every frame and sash is encased in scratch-resistant protective film, corner edge guards, and multi-layer shock-absorbing foam. Fully assembled or knock-down units are fixed inside fully enclosed, fumigated wooden cases or reinforced steel frame crates designed for crane and forklift handling during container loading.

We provide FOB, CIF, CFR, and DDP shipping terms. Our export logistics team prepares detailed packing lists with matching unit tags, commercial invoices, bill of lading documentation, mill test reports, and certificates of origin to simplify port customs clearance for importers globally.

Standard contract terms consist of a 30% to 50% deposit paid via Telegraphic Transfer (T/T) upon shop drawing sign-off, with the remaining balance settled prior to container dispatch or against the presentation of original shipping documentation. Irrevocable Letters of Credit (L/C at sight) may also be processed for large-scale enterprise contracts.

We provide a 10-year structural warranty on primary aluminium extrusions and PA66 thermal break bonds. Surface coatings carry 10 to 20-year non-fading guarantees depending on whether architectural powder or PVDF finishes are selected. Hardware mechanisms and sealed insulated glass units carry a standard 5-year replacement warranty.
