What DL Plastics does

DL Plastics B.V. (formerly De Lange Plastic Linings) is a Dutch family-owned B2B manufacturer and installer of flexible plastic foils, headquartered in Sint Annaparochie, Netherlands, with approximately 20 employees and a 5,500 m² production facility. Founded in 1960 by Mr. De Lange Sr. and restructured under its current name in 2009, the company supplies custom-fabricated liners, covers, and complete steel silo systems across four verticals: horticulture water storage (tankliners, steel silos, anti-algae and floating covers); agricultural manure storage (manure bags, closed liners, floating covers, air-inflated covers); concrete protection in wastewater treatment, sewage, biogas, and chemical storage facilities (T-linings, renovation linings, spray-applied DLPHS Lining, anchor plates); and petrochemical/industrial liquid-tight bottom sealing (HDPE foil for tank farms).

The company's technical platform revolves around proprietary materials (notably DelafleX, used in 90% of tankliners and backed by a 15-year warranty along with Food-Grade and Drinking Water certifications from a German testing institute) and certified welding capabilities (KIWA BRL-K, SCC*/VCA*, and Normec QS DIV.499.1130 welder qualifications) applied on-site by in-house specialists. Production spans custom plastic sheets, foil tarpaulins, floating polyolefin covers, spray lining systems, and CE-marked corrugated galvanized steel silos with storage capacity up to 4,000,000 liters.

DL Plastics monetizes through one-time hardware sales (tankliners, silos up to 4,000,000 liters, manure bags, HDPE bottom sealing systems), professional installation services performed by certified specialists, and a rental stream on the DL-Flex-Bag for temporary storage of manure, drinking water, and extinguishing water. Distribution combines direct enterprise field sales for large national and international projects with a regional dealer network (Hendic and Habo Drechtstede for silos; Wetcomb for India), supported by a heavy trade show calendar (GreenTech Amsterdam, AquaTech, WETEX Dubai, HortEx Vietnam, Horti Asia) and downloadable multilingual product brochures. The company claims project execution across the Netherlands, Europe, the Middle East, Asia, Africa, and Central and South America.

Direct peers

• Solmax International: One of the largest geomembrane and industrial liner manufacturers, supplying HDPE, LLDPE and PVC liners and floating covers for water basins, mining, environmental and agricultural containment. Closely comparable to DL Plastics on basin liners, manure covers, and floating cover technology, but at much larger scale.
• Layfield Group: North-American manufacturer of flexible geomembranes, floating covers and fabricated liners for water storage, agricultural and environmental applications. Closely comparable technology and product set to DL Plastics, particularly on floating covers and custom-fabricated containment liners.
• HUESKER Synthetic GmbH: German producer of geosynthetics and technical textiles including protection liners, sealing systems and reinforcement products for hydraulic, environmental and infrastructure applications. Overlaps with DL Plastics on industrial concrete protection, basin sealing and environmental containment solutions.

Broad incumbents

• SIMONA AG: German producer of plastic sheets, rods, pipes and welded fabrications (PE, PP, PVC, PVDF, E-CTFE) for industrial, chemical and water applications. Overlaps with DL Plastics on HDPE/PVC sheets used in tank liners, concrete protection and chemical-resistant construction, but with a far broader catalog and global distribution.
• CST Industries: Global manufacturer of bolted steel storage tanks (Aquastore, Peabody TecTank) for water, wastewater, fire protection, and dry bulk. Compares to the steel silo side of DL Plastics (Hendic partnership) on large-capacity water storage tanks, but at much larger scale and broader product line.
• AGRU Kunststofftechnik: Austrian manufacturer of industrial HDPE/PP sheets, liners and concrete protection products used in water, wastewater, mining and chemical applications.
