Panelized Water Storage Tanks for Philippine Commercial and Industrial Sites

A panelized water storage tank is assembled on site from factory-formed panels, bolted or clipped together, rather than poured as a single concrete structure or welded as one steel shell. JOHOB Hardware Trading supplies panelized tanks in FRP (fiberglass reinforced plastic), hot-dip galvanized (HDG) steel, and stainless steel, and each unit is sized and configured per project rather than sold off a fixed catalog. Panel construction means a tank can be built in sections small enough to move through tight site access, then assembled on a prepared foundation, which suits retrofit sites and upper-floor installations where a one-piece tank cannot be delivered intact. JOHOB sources panels through an ISO 9001 certified partner factory and supplies nationwide across NCR, Luzon, Visayas, Mindanao, and the PEZA, SBMA, and Clark zones. For projects that need the tank assembled and commissioned on site rather than delivered as a kit, our sister brand TankSmith handles turnkey panelized water tank installs, so the same panel system can be bought as supply-only or as a full install package depending on what the project needs.

FRP panels are lightweight and corrosion resistant, and are commonly specified where potable water storage needs WRAS-certified panels, since fiberglass does not rust or scale the way bare steel can. Hot-dip galvanized (HDG) steel panels carry a zinc coating that resists corrosion in general industrial and fire reserve applications, and tend to suit sites where impact resistance matters more than weight. Stainless steel panels cost more than FRP or HDG steel but are specified where a project's water quality standard or process requirement calls for a non-reactive, easy-to-clean surface, which is common in food and beverage, hospital, and hotel back-of-house installations. All three panel types are supplied through the same JOHOB quoting process: a buyer specifies the application (potable, fire reserve, process, graywater), the site constraints, and the required certification, and JOHOB matches that to FRP, HDG steel, or stainless steel panels sourced from an ISO 9001 certified, TUV SUD tested partner factory. None of the three materials is a universal default; the right choice depends on water use, site access, budget, and whether the buyer needs WRAS certification for potable storage.

Every panelized tank JOHOB supplies carries WRAS certification on the panel system used for potable water storage, which confirms the materials and design meet recognized requirements for contact with drinking water. Panels are produced through an ISO 9001 certified partner factory, meaning the factory's quality management system is independently certified, and are TUV SUD tested before they ship. These three certifications (WRAS, ISO 9001, TUV SUD) apply specifically to the tank panels themselves, separate from the CE marking JOHOB carries on electrical panels and material handling equipment elsewhere in its catalog. For procurement teams that need to document compliance before a purchase order is approved, JOHOB can provide certification references for the specific panel material and application requested, rather than a generic certificate that does not match the project's water-contact requirement.

JOHOB responds to RFQs for panelized water tanks within 1 business day. From there, lead time depends on whether the configuration is ex-stock or made-to-order: ex-stock panel configurations ship in 21 to 35 days, while made-to-order sizes, materials, or certifications take 45 to 90 days to produce. Philippine projects on a fixed turnover date should request a quote with the target delivery date stated up front, since panelized tanks are sized and configured per project rather than held as finished units in a fixed size range. Because the tank arrives as panels rather than one welded or poured piece, on-site assembly time is separate from the manufacturing lead time above; for projects that want the assembly timeline quoted alongside the supply timeline, JOHOB's sister brand TankSmith can quote a combined supply-and-install schedule so the project team is working from one date instead of two separate vendor timelines.

JOHOB supplies panelized water tanks nationwide, covering NCR, Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark economic zones. Standard 12% VAT applies to VAT-registered buyers on a panelized tank purchase. Buyers operating as PEZA or SBMA locators, or as exporters, qualify for zero-VAT treatment on the purchase, which procurement teams should flag at the RFQ stage so the quote is issued with the correct VAT treatment from the start rather than corrected after an order is placed. Pricing for panelized tanks is quote-based: JOHOB does not publish fixed prices for panel systems, since the final price depends on material (FRP, HDG steel, or stainless steel), size, certification requirements (such as WRAS for potable use), and site access for installation. A buyer in a PEZA or SBMA zone and a buyer in Metro Manila on standard VAT terms will see different final numbers on an otherwise identical panel specification.

To request a quote for a panelized water tank, a buyer specifies the application (potable, fire reserve, process water, or graywater), the required capacity, the site location, and whether the purchase qualifies for PEZA or SBMA zero-VAT treatment. JOHOB replies within 1 business day with a quote that states the panel material, lead time (21 to 35 days ex-stock or 45 to 90 days made-to-order), and applicable VAT treatment. Buyers who want the tank supplied and assembled on site as one package, rather than delivered as a panel kit for a separate installer, can request that JOHOB's sister brand TankSmith quote the turnkey install alongside the supply quote, so both numbers come from one point of contact instead of being coordinated across two vendors. This keeps responsibility for fit, certification, and delivery date with a single supplier rather than split between a tank seller and a separate contractor.
