GRP/FRP Modular Water Tank Catalog and Sizes in the Philippines

JOHOB's GRP/FRP water tank catalog is built around modular bolted panel construction: individual FRP/GRP panels bolt together on site to form a tank, so capacity scales by adding panels rather than by picking a single fixed-size unit off a shelf. This modular approach falls under JOHOB's Water Storage product category, which also covers HDG and stainless steel modular tanks, and is supplied for turnkey installation under JOHOB's sister brand, TankSmith. Because each installation is engineered to the specific building load profile, water-supply pressure, and available footprint, this catalog does not publish a fixed dimension or price table. Buyers instead submit a request for quote describing the intended use, whether for domestic water storage, fire reserve, or industrial process water, and receive confirmed capacity, panel configuration, and pricing specific to that site. JOHOB commits to responding to RFQs within 1 business day so buyers can move from inquiry to confirmed specification quickly. For buyers who need a reference point before submitting an RFQ, the related FRP tank product and pricing pages linked below outline the general configuration options and cost factors in more detail.

Every GRP/FRP tank in this catalog is built from panels carrying WRAS certification, confirming the materials are safe for contact with potable water. The partner factories producing these panels operate under ISO 9001 quality management systems, and panels are TUV SUD tested before they ship. Where a project also requires electrical equipment, such as pump and VFD panels feeding the tank, that equipment carries CE marking. On projects where the tank or an associated pressure vessel component falls under ASME scope, JOHOB sources components that meet that standard as well. These certifications are carried by the equipment itself, not by JOHOB as a local manufacturer: JOHOB sources GRP/FRP tank panels from a vetted overseas manufacturer and delivers them in the Philippines with local warranty and after-sales support, rather than fabricating the panels locally. For procurement teams that need certification documentation for a bid package, JOHOB provides the relevant certificates for the specific panel and equipment configuration quoted, since certification scope can vary by tank size and site requirement.

JOHOB's Water Storage category includes three modular tank materials: FRP/GRP, hot-dip galvanized (HDG) steel, and stainless steel, and the right choice depends on water use, site exposure, and budget rather than one material being universally best. FRP/GRP panel tanks are the most common choice in this catalog for potable water and process water storage because the WRAS-certified panel lining is corrosion-resistant and does not require the periodic recoating that steel tanks need. HDG steel tanks are typically specified where a project needs a lower upfront cost and the water use does not require potable-grade lining. Stainless steel tanks carry the highest material cost in the range and are typically specified for food-grade, pharmaceutical, or other applications where the stored liquid requires a non-reactive, easily sanitized surface. JOHOB's guides comparing FRP against stainless steel walk through lifespan and cost tradeoffs for buyers deciding between the two, and the RFQ process confirms which material fits a specific site once JOHOB has the load profile and intended use. Buyers do not need to resolve the material choice before requesting a quote.

JOHOB quotes two lead-time bands for GRP/FRP tanks depending on configuration: 21 to 35 days for ex-stock panel configurations, and 45 to 90 days for made-to-order configurations that require custom panel sizing or non-standard fittings. Delivery covers the Philippines nationwide, including NCR, Luzon, Visayas, and Mindanao, plus PEZA, SBMA, and Clark zones for buyers operating inside those economic zones. JOHOB responds to RFQs within 1 business day, so a buyer submitting a request on a weekday gets a confirmed specification and lead-time estimate back the next business day rather than waiting through a multi-day sales cycle. Because lead time depends on whether a configuration is ex-stock or made-to-order, the fastest way to get an accurate delivery date for a specific project is to submit the site details (location, intended use, required capacity range) through the RFQ form rather than assuming a single catalog-wide lead time applies to every tank.

JOHOB does not publish fixed prices for GRP/FRP tanks in this catalog; pricing is quote-based because each tank is sized to a specific site, and publishing a flat price list would misrepresent that cost before the actual configuration is confirmed. For VAT-registered buyers, standard 12% VAT applies to the quoted price. Buyers operating as PEZA or SBMA locators, or as exporters, qualify for zero-VAT treatment on the same equipment. Supply of the GRP/FRP tank itself runs through JOHOB as the industrial equipment supplier, while turnkey installation, meaning the full on-site assembly and commissioning of the modular tank, runs through JOHOB's sister brand TankSmith. Buyers who only need the tank panels delivered can work with JOHOB directly; buyers who need the tank installed and commissioned on site typically work with TankSmith for that portion of the project while sourcing through the same RFQ process. Either path starts with the same 1-business-day RFQ response.

This GRP/FRP water tank catalog is built for commercial, industrial, and institutional buyers across the Philippines rather than individual homeowners: procurement teams at manufacturing plants, facility managers at hotels and hospitals, operators of food processing and cold chain facilities, and developers building out PEZA, SBMA, or Clark zone sites. JOHOB's broader product range, which includes pumping and pressure systems, electrical panels, and fire protection tanks, means a buyer sourcing a GRP/FRP tank for a new building can also source the booster pump, VFD panel, and fire reserve tank that typically accompany it from the same RFQ. JOHOB's moat in this category is deep vertical content written for specific buyer types, commercial laundry, hotel, hospital, food processing, and SBMA/PEZA facilities, plus technical buying guides written to Philippine plumbing code (NSPC and NBC) rather than generic marketing copy. Buyers evaluating this catalog against other suppliers should look for that depth, technical guides tied to the actual code requirements their project needs to meet, not just a capacity list.
