Large 6m x 3m Heavy Duty Polytunnel with Reinforced Metal Hinged Door

If you’ve owned a standard polytunnel before, you’ll know the weakest point is almost always the door. Zips split, fabric tears, and access becomes frustrating — often after just one tough season.

This large 6m x 3m polytunnel is built differently.

Instead of a traditional zipped entrance, it features a strong metal hinged door — giving you reliable access, stronger structure, and long-term peace of mind, even on a larger tunnel.

The Upgrade That Makes the Biggest Difference: Metal Hinged Door

This isn’t just a small improvement — it’s a major durability upgrade.

• Exclusive opening metal hinged door (not a cheap roll-up zip door)
• No broken or stuck zips
• No tearing around the doorway
• Smooth, easy opening every time
• Stronger, more secure entrance
• Performs better in wind and bad weather

Heavy Duty Construction You Can Rely On

• Fully galvanised frame throughout for long-term rust protection
• 25mm diameter steel tubing (0.9mm thick) with strong frame bracing for added strength and stability
• Heavy duty polytunnel cover designed to resist ripping, rotting and UV damage

Designed for Real Growing Conditions

• Large roll-up side window for adjustable ventilation and airflow control
• Exclusive built-in rain collectors on each side to help manage rainwater runoff

Extend the Life of Your Cover

For maximum durability, we recommend insulating the metal frame using our Hot Spot Tape. This helps reduce friction and heat transfer, helping extend the life of your cover.

More Growing Space, Same Trusted Strength

The larger 6m x 3m size gives you significantly more room for plants, staging, or crop rows, while maintaining the same heavy duty frame, reinforced cover, and metal door reliability.

A Smarter Long-Term Choice

Choosing a stronger door, frame, and cover means fewer repairs, fewer replacements, and more time focused on growing — not fixing.
