Where we manufacture
Our production is based in Hong Kong, with tight quality control across the full range: cold-rolled steel stamping, cast-iron casting, aluminum extrusion, powder-coating, and anodizing all happen under one quality system. Because we control the line end-to-end, we can deliver consistency across repeat container orders and respond quickly to custom-size and private-label requests.
What we make
- Floor registers — cold-rolled steel and cast-iron, adjustable opposed-blade dampers, baked enamel and powder-coat finishes. Sizes 2"×10" through 8"×14".
- Ceiling diffusers — 4-way square, round step-down cone, louvered face, and 2×2 lay-in models for commercial and residential supply-air applications.
- Return air grilles — stamped, fixed-blade, filter-back, and eggcrate patterns in aluminum and steel, for residential and commercial return-air installations.
- Linear slot diffusers — 1, 2, 3 and 4-slot configurations in extruded anodized aluminum. Custom lengths up to 240 inches for modern architectural applications.
