What Pronal does

Pronal is a privately held French industrial company founded in 1961 and headquartered in Leers (near Roubaix), specializing in the design, manufacture, and installation of flexible structures built from elastomers, plastomers, and composite materials. The company's core manufacturing competence is vulcanization of elastomers (SBR, NPVC, EPDM, neoprene, polyurethane, PVC), supported by an in-house materials laboratory for expiry, chemical compatibility, and bespoke quality testing. Its product portfolio spans flexible storage tanks (citerne souple) for water, fuel, hydrocarbons, and dielectric oil; inflatable pipe plugs (obturateurs) including the OPAP anti-pollution, OHP high-pressure (up to 35 bar), OVO oval, and RGV steam-generator-replacement variants; air lifting cushions; volume compensators; flexible gas holders; pneumatic bottle grippers for bottling lines; worker safety systems such as the CE-certified Smartshore trench shield; and modular add-ons like the MPFM pumping/filtration/metering unit and the METEOR test bench developed with Velan SAS for nuclear valve testing.

The business operates a quote-driven (devis) enterprise field sales model with direct sales teams in France and wholly-owned subsidiaries in the USA, Malaysia, China, Hong Kong, and Portugal, supplemented by the SOFRAD HSE services subsidiary and the Strucflex by Pronal brand in Iberia. Revenue is generated through one-time sales of standard catalog products and custom-engineered bespoke solutions, alongside a growing professional services stream covering on-site pre-visits, installation, commissioning, operator training, and preventive/corrective maintenance. Customers are concentrated in regulated and mission-critical verticals including Oil & Gas, nuclear power, offshore platforms, aerospace ground operations, industrial safety (DECI, SEVESO), and specialized segments such as viniculture and rescue services. Pronal holds ISO 9001, 14001, and 45001 certifications, CE marking for Smartshore, PMUC material certification for nuclear use, and compliance with French fire tank and oval pipeline standards.
