Replacement Pergola Louvers: How to Order Blades for an Existing Pergola

t370-43

Replacement pergola louvers can usually be made to match an existing pergola if you provide the blade profile, length, spacing and mounting details. The safest route is to measure the old blades, photograph the pergola, and have a manufacturer check fit on site before production. Techno Kol Uzi produces made-to-measure iron and aluminum louver blades in its Tel Aviv factory.

Why You May Need Replacement Louvers

Pergola louvers rarely fail all at once. A blade may bend after a storm, a motor-driven system may stop turning evenly, or a section may corrode where water has collected for years. In many cases, only one or two blades need replacing, and the rest of the pergola is still sound.

Replacing only the damaged parts saves money and keeps the structure looking consistent. The challenge is matching the new blades exactly to the old ones, because even small differences in width or angle show clearly once the louvers are closed or open.

What to Measure Before You Order

Good measurements make the difference between a perfect fit and a return trip. Take the following details from the existing pergola:

Blade length and blade width
Blade thickness and profile shape
Spacing between blades and the axle or pivot position
Type of end connection, bracket or bearing
Material and finish, such as hot-dip galvanized iron or aluminum

If you cannot measure accurately, bring a damaged blade to the factory so the profile can be checked directly.

Photos and Details to Send Us

Clear photos help us understand the system before we measure on site. Send a wide shot of the whole pergola, a close-up of one blade end, a photo of the mounting bracket, and any visible marks or model numbers on the frame.

Also tell us how many blades you need, the approximate age of the pergola, and whether it is manual or motorized. A short written description together with the photos is usually enough to start the inquiry.

On-Site Check and Written Specification

After reviewing your inquiry, our team can visit the site to measure the existing louvers and check how the blades connect to the frame. This step confirms that the new parts will work with the current structure, not just look right on paper.

You will then receive a written specification and drawing describing the blade dimensions, material, finish and fittings. Please read it carefully and approve it before production starts, so that both sides agree on exactly what will be made.

Production and Finishing in the Factory

Once the specification is approved, the blades are manufactured in our factory at 37 Rival Street, Tel Aviv. Iron and aluminum parts are cut, formed and assembled to the measured dimensions. Where durability matters, finishing such as hot-dip galvanizing or powder coating is applied to protect against weather and corrosion.

Matching the color and surface finish of the existing pergola is an important part of the work. We will discuss this with you during the approval stage so that the new blades blend in with the rest of the structure.

Installation and Practical Tips

Replacement blades are installed by fitting the new pieces into the existing brackets or pivots and checking that they open and close smoothly. Before installation, clean the pivot points and check for wear, since a worn bearing can cause a new blade to stick or misalign.

Test the full range of movement after installation
Check that all blades sit at the same angle when closed
Keep a note of the specification for future orders

Frequently asked questions

Can you match louvers from an old pergola that is no longer sold?

In most cases yes, because the blades are made to measure in our factory rather than taken from a standard catalog. Providing the measurements and a damaged blade makes matching much easier.

Do I need to order all the blades at once?

It is best to order the full set if the existing blades are of different ages, since differences in finish can show. If only one or two are damaged and the rest are in good condition, we can discuss matching only the missing pieces.

Do you visit the site before production?

Yes, an on-site visit is part of the process so that measurements and fittings are checked against the actual pergola before anything is manufactured.

Can the new blades be powder coated to match the existing color?

Powder coating is one of the finishing options we offer. We will discuss color and finish during the approval stage so the new blades match the existing structure.

Common mistakes to avoid

The most common mistake is ordering from a rough measurement of length alone, without checking the blade profile and pivot details. Waiting until the old blades are badly damaged also makes matching harder, since the original dimensions may be difficult to recover.

Our recommendation

Bring one damaged blade or a clear photo of the end connection to the first conversation, and ask for a written specification before approving production. This single step prevents most fitting problems.

Summary

Replacement pergola louvers can be made to match your existing structure when the blade profile, dimensions and fittings are measured carefully and confirmed on site. Techno Kol Uzi makes them to measure in Tel Aviv.
