HPDE Membrane: Superior Engineering Quality for Improving Your Project Performance
How to choose high-quality HPDE geomembrane？
Choosing high-quality HPDE geomembranes is the key to ensuring the success of engineering projects. Here are a few suggestions:
Select well-known brands: Selecting suppliers with well-known brands and good reputation can ensure product quality and after-sales service. Shandong Haoyang Environmental Protection Co., Ltd. has high-tech comprehensive service capabilities in the field of environmental protection, including environmental protection engineering consulting, design, construction, environmental protection engineering material research and development and manufacturing, environmental pollution control, hazardous waste treatment and disposal investment and operation. It has a number of inventions, utility model patents and provincial-level scientific and technological achievements appraisal. Its products are widely used in many environmental protection fields such as water conservancy, transportation, urban domestic waste disposal, industrial tailings pond, environmental pollution control and hazardous waste treatment and disposal.
In addition, we have passed ISO9001 Quality Management System, ISO14001 Environmental Management System, OHSAS 18001 Occupational Health and Safety Management System Certification and CQC Environmental Protection Product Certification. We are a "high-tech enterprise", "national quality and integrity enterprise", "enterprise technology center in Shandong Province", "enterprise that abides by contracts and respects credit", and our products have won the titles of "stable and qualified products in national quality inspection" and "Shandong Trademark".
Check product quality: When purchasing, pay attention to checking the quality of the product, including tensile strength, tear strength, corrosion resistance, and other indicators to ensure compliance with requirements. Each batch of our products is randomly sampled in groups and tested in the laboratory before being packaged and shipped.
