Tailored Ventilation & Architectural FabricationWe collaborate directly with E&M contractors, architects, and developers to engineer and manufacture non-standard air diffusers, oversized vents, and custom site equipment.
Powder-Coated Finishes: Exact color matching (BS 4800 standard) to seamlessly blend into complex architectural ceilings.
Non-Standard Deflection: Custom fixed-angle diffusers (e.g., 60-degree airflow deflection) designed for specific acoustic and throw requirements.
High-Grade Materials: Fabrication available in powder-coated aluminum, stainless steel, and heavy-duty galvanized steel.
Cityplaza Mall (2/F & Atrium): Participated in the air distribution redesign alongside main contractors. Fabricated and installed over 150 custom powder-coated diffusers with 60-degree deflection and curved atrium vents. (Expansion for 3/F and 4/F underway, ~80–100 additional units).
Designed specifically for Hong Kong’s low false ceiling voids and tight window clearances, Wo Lee's extendable duct series replaces bulky pipes with an ultra-slim, field-adjustable profile.
Key Features & On-Site Advantages:
① Dual-Axis Telescoping: Adjusts smoothly in both height and depth to fit low false ceilings and tight wall clearances.
② Fully Customizable: Tailored to match your specific site dimensions, pipe diameters, and powder-coated finishes.
③Built-in Protection: Features an integrated backflow damper and insect mesh to block unwanted odors, drafts, and pests.

Faster Installations: Slide to fit, seal with silicone sealant, and secure—reducing labor hours per site.
Preserves Ceiling Height: Leaves maximum living space below without compromising exhaust airflow efficiency.
Leak-Free Fit: Precision-engineered overlap joints ensure airtight airflow for kitchen hoods and high-capacity bathroom heaters.
Built in strict accordance with BS 1710:1984, BS 4800 color standards, and the Architectural Services Department (ArchSD) General Specification for Building, our ID-Bands and ID-Labels streamline site inspection and long-term facility management.
ID-BAND (Pipeline Color Bands):
Supplied in 400mm X 25M rolls with high tack Nitto 5000NS double sided adhesive for rapid application on plumbing, HVAC, gas and other conduit systems
ID-LABEL (Ductwork Identification):
150mm self adhesive triangular labels indicating air service types ( Conditioner, Fresh, Foul, Exhaust) and airflow direction.
Designed for Hong Kong’s fast-paced construction and commercial fit-out sector, our industrial-grade galvanized slotted channel system delivers a rapid, bolt-together solution for heavy-duty MIMEP supports, vertical risers, and plant room framing. Fully aligned with MiMEP (Modular Integrated MEP) standards, this system eliminates on-site hot work while drastically lowering labor costs and installation time.
No Hot Work Permits: 100% bolt-assembled. Bypass Fire Services Department (FSD) welding permits, fire-watch expenses, and live-building downtime.
MiMEP Compliant: Designed for off-site pre-fabrication and rapid on-site installation—cuts labor time by up to 50%.
HK Weather Resistant: Heavy-duty Hot-Dip Galvanized (HDG) and ZMA coatings resist high humidity and coastal corrosion.
Fully Adjustable: Continuous slotted channels allow instant field levelling and expansion with standard hand tools.
