Replacement Shower Drain Part Factories & Factory for the Melbourne Market

In Melbourne high-rises, screw-down floor grates frequently fail because the brass or plastic threads embedded in the lower puddle flange become stripped, clogged with calcium efflorescence, or cross-threaded over years of service. A snap-in strainer grid utilizes high-tensile austenitic stainless steel side tension prongs that grip the inner smooth bore of the waste outlet through frictional radial force. This eliminates screws entirely, allowing maintenance teams to pop the strainer out in 2 seconds for snake access or hair cleaning, and press it back flush without risking screw shearing or thread damage.

Efflorescence in Victorian bathrooms occurs when shower water penetrates the grout joints, travels across the bedding screed, and cannot quickly discharge down the waste riser, depositing white calcium salts as it dries. JANA’s replacement trim assemblies and strainer collars feature precision-beveled edges and calibrated drainage slots that align precisely with the screed level, providing clear weep-hole evacuation paths into the 100mm or 80mm PVC waste riser in full compliance with AS 3958.1.

We prioritize heavy-duty, lead-safe, and dezincification-resistant (DZR) forged brass conforming to CW602N/AS 2345, alongside premium SUS304 and marine-grade SUS316 stainless steel. These alloys eliminate zinc leaching when exposed to aggressive chlorinated municipal water, domestic cleaning acids, and coastal marine air common along Victoria’s coastline, ensuring the drain will not become brittle or suffer stress corrosion cracking.

Yes. We currently produce standard imperial and metric outer diameters: 3-1/4", 3-3/8", 4", 4-1/4", 4-1/2", and 4-5/8". If your Australian wholesale brand requires a proprietary diameter (such as 86mm, 92mm, or 115mm) or custom flange depth to fit a legacy brand’s puddle ring, our in-house toolroom can build progressive stamping dies and produce test sample runs in our Yuhuan headquarters within 20 to 25 days.

For standard catalog items (such as the JN-6320 through JN-6330 series), our minimum order quantity (MOQ) typically ranges from 500 to 1,000 units per SKU depending on surface finish (Chrome, PVD Matte Black, Brushed Brass). Production lead times generally stand at 30 to 40 days from factory release. Maritime transit from Ningbo or Laem Chabang port directly to Melbourne takes roughly 14 to 20 days on major shipping lines (COSCO, Maersk, ANL).

Our dual-base footprint (China HQ founded in 1998, plus our new 14,400 m² automated facility in Kabinburi, Thailand operational since December 2023) gives Australian importers maximum security. Importers can pivot production origin smoothly to navigate evolving trade policies, take advantage of ASEAN-Australia-New Zealand Free Trade Area (AANZFTA) provisions, and prevent supply chain single-point failures.
