Quality Control Standards

Precision B2B Fabrication & Delivery Workflow

Every sliding door project manufactured at our Al Sajaa, Sharjah works follows a strict 4-phase quality assurance protocol prior to export container loading.

1. Shop Drawing & Engineering

Detailed CAD/BIM section drawings, wind load calculations (ASTM E330), and thermal simulations are generated and submitted for consultant sign-off.

2. CNC Machining & Crimping

Extrusions are precision-cut, CNC-milled for locks and drainage slots, and hydraulically corner-crimped with structural epoxy sealants for rigid corner strength.

3. Glazing & Pressure Testing

Double/triple glazed units are installed using structural silicone and EPDM gaskets, followed by factory air permeability and water chamber leak tests.

4. Craters & Export Shipping

Finished door modules are wrapped in protective PE film, corner-shielded, and packaged into custom ISPM-15 heat-treated wooden crates for secure global freighting.

Aluminium Sliding Doors — Frequently Asked Procurement Questions

Technical, financial, and logistical insights curated by our senior facade designers and export engineering team to assist global purchasing managers.

Standard sliding doors rely on continuous brush seals that remain in contact with the track at all times, creating friction during operation and gradual seal wear over time. In contrast, Lift & Slide systems utilize specialized gear mechanisms. Turning the handle 180 degrees physically lifts the sash 5mm off the frame track, disengaging the continuous compression gaskets. This allows sashes weighing up to 400kg to glide effortlessly. When closed, lowering the door locks it down against continuous EPDM rubber seals, delivering vastly superior water tightness (Class E900), air tightness (Class 4), and acoustic isolation.

Aluminium is an excellent thermal conductor. Unbroken aluminum extrusions allow outdoor heat to transfer directly indoors, driving up air conditioning energy consumption. Thermal break profiles introduce a low-conductive structural polyamide barrier (PA66 GF25 reinforced with 25% glass fiber) between the inner and outer aluminium extrusions. This thermal bridge halts conductive heat transfer, lowering total frame U-values from over 5.0 W/m²K down to 1.1 - 1.5 W/m²K, which typically reduces indoor HVAC cooling loads by 25% to 35% in high-ambient heat environments.

For large-panel sliding sashes exceeding 2.5 meters in height, structural glass calculation is mandatory to prevent wind-induced deflection and thermal stress cracking. We specify fully tempered (toughened) safety glass, often combined with laminated safety glass (e.g., 6mm Low-E Tempered + 12A/16A Argon Spacer + 6mm Clear Tempered, or 8mm + 1.52mm PVB + 8mm Laminated). Low-Emissivity (Low-E) coatings applied to surface #2 or #3 reflect far-infrared heat while allowing visible light transmittance (VLT), keeping interior spaces bright and cool.

For project sites within 5 kilometers of ocean coastlines or high-salinity marine air, standard powder coatings are susceptible to filiform corrosion. We recommend either Qualicoat Class 2 / Class 3 Super-Durable architectural powder coating (minimum 60-80 microns depth) or Marine-Grade Hard Anodizing (20-25 microns conforming to BS EN ISO 7599). Both options withstand 2,000+ hours of continuous neutral salt spray (NSS) chamber testing without blistering, peeling, or fading.

Yes. From our Al Sajaa, Sharjah manufacturing plant, we regularly fabricate, package, and ship containerized volume packages for real estate developers, contractors, and building supply distributors globally. Bulk orders receive unified extrusion batching, precision pre-drilled assembly channels, labeled component lists, and custom ISPM-15 export crate packaging to ensure seamless jobsite assembly.

Zero-threshold or flush sliding doors utilize concealed sub-floor stainless steel drainage troughs situated beneath the tracks. Rainwater running down the exterior glass faces flows directly into linear slots, passing through one-way rubber flap check valves into an integrated drainage channel connected to building storm pipes. This prevents back-siphoning during heavy wind-driven rain while maintaining step-free accessibility.

Standard profile extrusions in stock finishes (Matt Black, Anthracite Grey, White) generally require 2 to 3 weeks for CAD approval, precision cutting, glass tempering, and assembly. Customized powder coat colors, specialized anodizing, or custom-extruded dies require 4 to 6 weeks. Phased factory dispatches are coordinated directly against main contractor site master schedules.

Aluminium sliding doors require minimal maintenance. Track channels should be vacuumed every 3 to 6 months to remove sand, dust, and debris that accelerate roller wear. EPDM weather seals should be wiped clean with mild soapy water annually, and stainless steel multi-point locking gear should receive light silicone spray lubrication every 12 months. Track rollers require no repacking as they feature sealed, self-lubricating stainless steel ball bearings.
