Water tank manufacturer FAQ
01What kind of water tank manufacturer is LVJIA?
We are a water tank manufacturer, not an agent. The moulds, the hydraulic presses, the shearing and welding lines and the galvanizing are all inside our 11,000 m² plant in Dezhou, Shandong, and the company has run since 2015. Buying from a direct water tank manufacturer means the price you see is the factory price and the lead time you are quoted is our own schedule, not someone else’s. That is the difference a direct water tank manufacturer makes.
02Which water tanks do you manufacture?
Five systems: GRP/FRP/SMC sectional, stainless steel SUS 304/316/316L, hot-dip galvanized, enamel glass-fused-to-steel and BDF underground. Using one water tank manufacturer for all five keeps the panel sizes, bolt pattern and sealing strip consistent, so a site that mixes a rooftop SMC tank with a buried BDF reserve gets parts that behave the same way, all from one water tank manufacturer.
03What is the smallest and the largest tank you build?
From 0.125 m³ up to 5,000 m³ in a single tank, with panels 6–22 mm thick and heights to about 5 m. Everything between is cut to size by the water tank manufacturer. Anything in between is made to order against your footprint, so you are not forced into a standard size. Few water tank manufacturer catalogues span that whole range from one factory.
04Are the tanks safe for drinking water?
Yes. Our SMC panel passed all 20 test items of GB/T 17219-2025, report SP2630502, May 2026, and we use non-toxic rubber seals. Ask any water tank manufacturer for the report number rather than a claim — we will send the full certificate with the quotation. Every batch from this water tank manufacturer is traceable to its own report.
05Do you accept OEM and ODM orders?
We do. Partitions, insulation, internal and external ladders, manholes, pipe connections, colour and your own branding are all available from the water tank manufacturer. Working with a factory that owns its tooling is what makes a genuine OEM run possible instead of a relabelled stock item.
06How are the tanks packed and shipped?
Flat-packed by the container at the water tank manufacturer and bolted together on your site, which is how a water tank manufacturer keeps freight sensible on a 1,000 m³ order. We ship FOB, CFR, CIF or EXW through Tianjin or Qingdao and regularly serve the Middle East, Africa, North America, Southeast Asia and mainland China. The container loading plan is prepared by the water tank manufacturer before despatch.
07What certificates does the factory hold?
WRAS certification. ISO 9001 for quality management, ISO 14001 for environment, ISO 45001 for occupational health and safety, plus CE. We have also passed an SGS supplier assessment with an on-site check. Those four are the baseline a water tank manufacturer should be able to show before you shortlist it. Copies are issued with every quotation.
08How long does production take?
Send the capacity, the footprint you have and the destination port, and you will get a drawing, a bill of materials and a firm price. Quotations come from the water tank manufacturer itself, never a reseller. Once the drawing is approved a typical sectional order leaves our water tank manufacturer site in Dezhou within a few weeks; your water tank manufacturer should always confirm the exact date in writing with the proforma invoice.
Still comparing suppliers? Tell this water tank manufacturer the capacity and the destination and we will price it. A water tank manufacturer with its own plant answers in hours, not days.
