What is the difference between Vertical and Horizontal water tanks, and how do I choose?

Vertical Tanks (PT-Series, 200L to 50 Tons): Ideal for space-saving ground or rooftop installations where vertical clearance is available.

Horizontal Tanks (W-Series, 500L to 20 Tons): Feature a lower center of gravity, making them perfect for mobile transport on trucks, agricultural trailers, or height-restricted spaces.

Are these tanks pre-drilled for pipe connections, or do they ship solid?

By default, our tanks ship with a solid, unperforated surface to ensure complete integrity during transport. However, we offer full pre-drilling and custom fitting integration—including threaded joints, double-ended studs, and welded PE flanges for inlets and outlets—based on your specific piping requirements.

What is the expected service life and outdoor weather resistance of these tanks?

Built with anti-aging, UV-stabilized PE material and reinforced horizontal ribs, our tanks have a designed service life of 8+ years. They withstand outdoor temperatures ranging from -10°C to 40°C, resisting sun degradation, impact, and extreme weather without cracking or warping.

Do you support custom wall thickness, color options, or company logo branding (OEM/ODM)?

Yes! As a source manufacturer, we provide comprehensive OEM/ODM services. We can adjust wall thickness for high-density liquid storage, offer custom colors (White, Blue, Black, Yellow), and apply personalized company logos for bulk wholesale and engineering projects.
