How to build a better cylinder.

Using a highly automated manufacturing process, every batch undergoes rigorous hydrostatic and leakage testing.

STEP 1
The Seamless Liner

A High-Density Polyethylene (HDPE) inner shell is created using a blow molding process to ensure it is completely gas-tight.

STEP 2

The Valve Boss

A metal or composite fitting is installed at the top to allow for precise valve stem installation later.

Robotic arms wind epoxy-impregnated fiberglass or carbon fiber around the liner. This multi-axis pattern maximizes structural strength with incredible precision.

STEP 3
Robotic Multi-Axis Winding
STEP 4
The Heat Cure

The cylinder is cured in an oven to solidify the resin, creating a durable and inseparable composite structure.

An injection-molded, durable plastic outer casing is added to shield the tank from UV damage and heavy impacts.

STEP 5

Impact Protection

Safety you can see.

Safety isn't just about meeting codes; it's about how the tank behaves in the real world.

Internal integrity

There is no risk of hidden internal rust weakening the structure over time.

Non-fragmenting design

In the event of a failure, composite cylinders tend to vent gas rather than exploding violently.

Explosion-proof by design

Unlike steel, the composite structure will not explode of fragment. It is engineered to remain intact under extreme heat or high pressure.

Frequently Asked Questions

Are composite cylinders safe?

Yes, composite cylinders are designed to be non-explodable, corrosion-resistant, and safer than traditional propane tanks.

What materials are used?

Our cylinders use advanced composite materials that make them lightweight, durable, and resistant to corrosion for long-lasting use.

How portable are they?

Composite cylinders are significantly lighter than metal tanks, making them easy to carry and ideal for outdoor activities and travel.

Where are cylinders made?

All composite cylinders are manufactured with trusted overseas partners and certified in the U.S., ensuring high quality and compliance with safety standards.

Can I refill them?

Yes, composite cylinders are refillable at authorized propane suppliers across the country.

What about environmental impact?

Our composite cylinders reduce waste by lasting longer and resisting corrosion, contributing to a safer and more sustainable propane solution.
