Sanitary Finishes, Ductwork Metallurgy & Construction Hardware
To ensure complete elimination of bacterial niches, dead pockets, and stagnant air zones, BTI cleanrooms integrate verified materials:
AISI 304/316L Return Air Risers
Low-level return air grilles and vertical extraction risers fabricated from AISI 304/316L with perforated micro-screens and cleanable pre-filter retainers.
R50 Extruded Aluminum Coving
All wall-to-wall, wall-to-ceiling, and wall-to-floor intersections sealed with radius 50mm anodized or powder-coated aluminum concave covings.
Airtight Doors & Interlocks
50mm flush cleanroom swing doors with automatic EPDM bottom drop seals, electromagnetic interlocks for personnel airlocks (PAL) and material airlocks (MAL).
Epoxy & PU Self-Leveling Floors
High-chemical-resistance, anti-static solvent-free epoxy flooring (3mm thickness) seamless with cleanroom cove bases preventing chemical and solvent erosion.
BTI Direct Factory Indenting vs. Traditional Local Stockists
Comparing BTI's direct cleanroom engineering indenting model against local Pakistani fabricators and distributors.
| Evaluation Parameter | BTI Factory Direct Indenting | Traditional Local Stockists |
|---|---|---|
| 1. Capital Expenditure (Capex) | Direct Ex-Works (EXW) OEM price eliminating middleman markups (30%–50% savings) | Heavily marked-up local retail pricing with local workshop overhead added |
| 2. Custom Engineering & Tooling | Custom manufactured to precise architectural layout, exact ceiling heights & riser cutouts | Manual field cutting with exposed raw sheet edges and poor joint seals |
| 3. Metallurgy & Sanitary Finish | Certified antimicrobial PVDF coated GI or SS 304 skins, certified Class A1 non-combustible | Low-density uncertified EPS cores prone to mold, warping, and severe fire risk |
| 4. Pre-Shipment Inspection (FAT) | AHU factory test logs (EN 1886 leakage & thermal deflection), panel flatness inspection | Zero pre-shipment tests; AHUs assembled with mismatched uncertified fans |
| 5. Regulatory Compliance (DRAP / cGMP) | Full qualification dossiers: DQ, IQ, OQ, PQ, DOP filter testing & smoke pattern mapping | No qualification documentation; fails DRAP cleanroom validation audits |
| 6. Local SAT & Engineering Accountability | Turnkey installation and on-site SAT by certified HVAC engineers and cleanroom specialists | Supply-only delivery; buyer forced to coordinate independent third-party duct installers |
