Trellis posts fail. Your harvest pays for it.
Wood rots underground.
CCA-treated posts break down in the soil. Fungal growth, insect infestation, structural failure. You're replanting into a system that's already decaying.
Steel rusts and corrodes.
Moisture eats through coatings over times. Posts weaken under the tension your trellis demands. Replacement disrupts your growing cycle.
You replace them.
Over 20 to 30 years, most growers rebuild their trellis system 3 to 5 times. The posts, the labor, the downtime. Every cycle costs you a season.
Proven overseas. Now made in America.
Prestressed concrete trellis posts have been the standard in European agriculture since the 1960's. Italian manufacturers have been producing tens of thousands of concrete posts per day for vineyards and orchards across Europe for over 60 years. In Italy, wood posts are the exception, not the rule. This isn't new technology. It's established, field-tested, and proven on millions of acres overseas. Jensen brought that same approach to the U.S. with Harvest Pillar, manufacturing prestressed concrete trellis posts at our facility in Kingsburg, California using European-made equipment and methods. The same material used in bridges, water systems, and utility structures. Now sized for trellis work on your land.
Applications
Built for Long rows
Recurring maintenance and labor costs from replacing and repairing trellis systems add up fast. Harvest Pillar resists the pests, diseases, rust, and toxins that destroy wood and steel setups. Holds wire tension across long runs without leaning or shifting. Set your trellis once and focus on growing.
Designed with Sustainability in Mind
Propping up orchards takes a toll on your trellis system. Harvest Pillar will last as long as the tree it's supporting, so all you need to worry about is taking care of your harvest.
Your Yard, Your Custom Posts
Hop Yards require taller posts than orchards or vineyards. Harvest Pillar allows posts with custom lengths up to 24' tall, ensuring your harvest is your main focus.

How Harvest Pillar is Made.
Prestressed, precast concrete. The same proven technology used in bridges and highway structures, sized for agriculture.
Steel Cables Stretched
Four strands of braided high-carbon steel cable are stretched 18 inches beyond the 240-foot casting beds.
Concrete Poured
Portland cement, natural gravel, and sand are poured around the tensioned cables and allowed to cure.
Cables Released
When the cables are cut, they recoil and compress the concrete. This prestressing gives each post its strength and flexibility.
Cut to Length
Posts are cut to your specified height. Custom lengths available. Every post is inspected before shipping.

Why growers are switching to concrete.
No Rot. No Rust.
Wood fails underground. Steel corrodes above it. Concrete doesn't have either problem. It handles moisture, pests, and time.
Organic Compatible.
Qualifies for organic production immediately. No three year transition period required like CCA-treated wood posts.
Lifetime Warranty
Every post. No exceptions. Built to outlast the vineyard or orchard it supports. You buy it once, you install it once.
Lower Lifetime Cost.
Higher upfront. But over 20 to 30 years, wood gets replaced 3 to 5 times. The posts, the labor, the time. Every cycle.
Reusable and Moveable
Pull them and move them. Replant a block and take your posts with you. Try that with rotted wood.
Uniform and Interchangeable.
Consistent dimensions mean brackets and accessories work across your entire operation. No post-to-post variation.
What Growers are Saying
We went through wood options, we went through steel options. We ended up going with concrete because nothing is going to bring them down.
Sciabica Family Farms, Modesto, CA
Prestressed concrete posts offer a reliable solution for growers looking to maximize longevity, repeatability, and strength. With a committed domestic producer, availability is now unquestioned.
TrellX, Prasser, WA
It's better than having treated wood that's going to bust and break over time. I'm excited that somebody is making them here in the U.S.

The Math on Trellis Posts.
A wood trellis costs less up front. But most vineyards and orchards outlast their posts by decades. You end up replacing them 3 to 5 times.
Wood Posts
Lifetime: 5 to 15 years
Replacements: 3 to 5 times over 50 years
Lowest upfront. Highest lifetime.
Steel Posts
Lifespan: 15 to 25 years
Replacements: 1 to 3 times over 50 years
Moderate upfront. High lifetime.
Harvest Pillar
Lifespan: Lifetime. Guaranteed.
Replacements: Once. That's it.
Higher upfront. Lowest lifetime.
