Industrial facilities, aquaculture farms and sewage treatment plants face consistent material failure issues when lining storage vessels and outdoor basins. Steel rusts under acidic wastewater, PVC degrades from long-term chemical contact and low-density plastic cracks under heavy liquid pressure.
Industrial Grey HDPE Sheet delivers a cost-effective, long-lasting alternative built to withstand corrosive fluids, continuous water immersion and outdoor UV exposure. As a reliable High Density Polyethylene material, standard HDPE Plastic sheets outperform many common lining panels with low water absorption and exceptional impact resistance.
AHD, a 32-year professional producer of Polyethylene Sheet and full engineering plastic profiles, supplies factory-direct grey HDPE liner panels that are specifically designed for wastewater treatment, chemical tank linings, aquaculture ponds, and more.
Key Physical & Chemical Performance of Grey HDPE Sheet
Grey HDPE Sheet stands out among lining materials due to stable physical indicators compliant with international plastic industry standards.
Density range of AHD HDPE Sheet: 0.950–0.965 g/cm³, far denser than LDPE’s 0.910–0.925 g/cm³.
Water absorption rate below 0.01%, eliminating swelling risks for long-term liquid storage.
Operating temperature range: -40°C to +80°C, suitable for hot acidic sewage and ambient aquaculture water.
Outstanding acid & alkali resistance: inert to hydrochloric acid, sulfuric acid, sodium hydroxide and common industrial wastewater mixtures.
This Chemical Resistant HDPE Sheet avoids rust, oxidation and chemical erosion. Most municipal sewage plants replace steel liners every 3–5 years, while UV stabilized grey HDPE liner for outdoor wastewater tanks from AHD maintains full performance for over years with minimal surface aging.
Every batch of our High Density Polyethylene Sheet passes third-party SGS testing before shipment, with a product performance pass rate above 99.8%. We produce Thick grey HDPE sheet for acidic wastewater storage tank ranging from 3mm to 50mm, matching small lab chemical containers and large 40-foot sewage lagoons.
Three Main Application Scenarios for Fabricable Industrial Grey HDPE Board
1. Wastewater Containment & Sewage Lagoon Lining
Leak-proof HDPE sheet for wastewater containment basins serves as the primary barrier for municipal sewage lagoons, factory wastewater sedimentation tanks and rainwater waste storage pits.
Sewage facilities frequently encounter fluctuating liquid levels and abrasive suspended particles in wastewater. Non-corrosive grey HDPE plastic sheet for chemical plant lining resists friction from sediment and corrosive mixed waste liquids without developing pinhole leaks.
Field installation teams confirm Fabricable industrial grey HDPE board for chemical vessel liner can be hot-welded seamlessly on-site. Welded seams form a fully impermeable layer to stop wastewater seepage into soil, complying with environmental containment regulations in Europe, Southeast Asia and Africa.
Custom size grey HDPE sheet for chemical containment lining is cut and welding per client’s tank dimensions, removing material waste and lowering overall lining construction costs by 18–25% compared to generic fixed-size panels.
2. Chemical Plant Vessel & Reactor Internal Lining
Chemical processing workshops store, mix and transport strong corrosive media that quickly degrade conventional lining materials. Low maintenance HDPE sheet for corrosive chemical media cuts routine upkeep costs for chemical manufacturers significantly.
Chemical resistant grey HDPE panel for sewage lagoon and industrial chemical tanks requires no regular anti-corrosion coating reapplication. AHD’s factory production line adds anti-oxidant additives during extrusion, removing the need for quarterly surface maintenance work.
3. Aquaculture HDPE Basin Liner for Fish & Shrimp Farming
Aquaculture HDPE Basin Liner solves two core farming challenges: water leakage and algae adhesion. Grey pigment integrated into the HDPE plastic raw material blocks sunlight penetration, slowing algae growth and reducing water cleaning frequency.
Outdoor aquaculture pools rely on UV stabilized grey HDPE liner for outdoor wastewater tanks to resist intense sun radiation in tropical regions. Thin plastic liners turn brittle after one year of outdoor use, yet AHD’s grey HDPE aquaculture panels retain flexibility even under year-round direct sunlight.

Volume purchase preferential pricing for wastewater treatment contractors, chemical manufacturers and large aquaculture enterprises. Our sales team creates exclusive quotation plans for bulk orders.
Where to buy industrial grey HDPE sheet for tank lining without middleman markup? Direct cooperation with AHD eliminates intermediate distributors, cutting overall procurement costs while guaranteeing consistent product quality for long-term project orders.
Q1: What thickness of grey HDPE sheet do I require for a waste water tank liner?
3-6mm Thickness grey HDPE sheet for acidic wastewater storage tank for indoor small wastewater tanks below 10m³ are good. For large sewage lagoons and outdoor chemical storage vessels, panels of 10-30mm are needed to resist impact, UV rays and heavy liquid pressure. Get in touch with our team today and we will recommend the right HDPE sheet thickness for you.
Q2: Can you weld industrial grey HDPE plastic sheet to make a leak proof chemical lining?
Hot Wedge and extrusion welding supports Fabricable industrial grey HDPE board for chemical vessel liner Yes The seams are an integral waterproof barrier, fully meeting environmental containment standards. AHD can supply matching HDPE welding strips with orders of liner sheet upon request.
Q3. How long will the UV stabilized grey HDPE liner last in an outdoor aquaculture pond?
Grey HDPE liner for outdoor wastewater tanks with imported anti-UV additives, UV stabilized. Under full-sun in the tropics, the panels retain full structural integrity for 12-18 years, substantially more than cheap unmodified HDPE liners that degrade within 2-4 years.
Industrial Grey HDPE Sheet continues to be the most balanced lining material for wastewater containment, chemical plant vessels and aquaculture farming basins in terms of service life, corrosion resistance and total ownership cost.
