- Most High Tunnel systems ship via Partial Truck Load (PTL) via Seneca Logistics group; this means that half of a standard 18 wheeler is rented out for the transport of the structure. The reason we use this mode of shipping is outlined more below
More on Partial Truck Load Shipping (PTL)
- The reason we ship via Partial Truck Load shipping is that it allows us to send larger steel components and hoop sections to our customers.
- Larger individual steel components and hoop sections means you will have less connection points to make with screws and bolts (easier installation)
- Larger individual steel components and hoop sections means stronger steel components and hoop sections; the less connections you need to make the stronger your structure
- Minimum Length for this structure is 20 ft. and the maximum length is up to 144 ft. long or more (depending on your needs)
- As length of greenhouse structure increases it will become more and more important to incorporate additional ventilation features into your structure
